Seasonal limnetic feeding regime of the “robalo” Eleginops maclovinus (Valenciennes 1830), in the Valdivia river, Chile
Provedor de dados: 72
Autores: Pequeño,Germán; Pavés,Héctor; Bertrán,Carlos; Vargas-Chacoff,Luis.
The “robalo” Eleginops maclovinus (Valenciennes 1830) is a common fsh in the littoral, estuaries and rivers (under tidal effects zone) of southern South América, including the Falkland islands. The feeding habits of this species is known mainly in the two frst mentioned habitats, where it consumes mostly animals from marine and estuarine origin. However, little is known about its seasonal feeding habits in limnetic environments. It is only assumed that it has to eat preys from freshwater origin. In the present study, 127 specimens of E. maclovinus were analysed, 119 of which had stomach contents. The zoophagic tendency of the species is corroborated, but also animáis from low salinities and limnetic salinities were found to be consumed inthe freshwater...

Diet of Hemigrammus marginatus (Characiformes: Characidae) in the Upper Contas River, Diamantina Plateau (Bahia, Brazil)
Provedor de dados: 76
Autores: Barreto,Silvia B.; Silva,André T.; Souza,Fabiane B.; Jucá-Chagas,Ricardo.
ABSTRACT Studies on the composition of fish diet and on how species exploit food resources are especially relevant in tropical freshwater systems, where dietary plasticity is a commonly used strategy. In this study, we analysed the food spectrum and the environmental, seasonal and ontogenetic variations in the diet of a characid species [Hemigrammus marginatus Ellis, 1911 (Characidae)] in the region of the Upper Contas River, in the Diamantina Plateau, Brazil. We verified an omnivorous/invertivorous and opportunistic food habit, with predominance of insects and microcrustaceans, followed by filamentous algae. Seasonality did not alter the food resources used by the species. However, differences were detected in the dominant categories when comparing the...

Análise comparativa entre tipos de alimentação de Micrurus corallinus (Serpentes, Elapidae) em cativeiro
Provedor de dados: 76
Autores: Serapicos,Eliana de Oliveira; Merusse,José Luiz Bernardino.
Micrurus corallinus (Merrem, 1820) kept in laboratory animal rooms swallow voluntarily various colubrid species. The most accepted species belong to the genera Sibynomorphus Fitzinger, 1843, Oxyrhopus Wagler, 1830 and Liophis Wagler, 1830. The voluntary feeding guaranteed resistance against pathogenic agents. The forced feeding was unsatisfactory due to stress resulting from handling, feeding frequency (30 days), susceptibility to pathogenic agents and high occurrence of pathologies.

Biologia alimentar de Steindachnerina brevipinna (Characiformes, Curimatidae) do rio Ibicuí-mirim, Rio Grande do Sul, Brasil
Provedor de dados: 76
Autores: Giora,Júlia; Fialho,Clarice B.
The feeding biology of Steindachnerina brevipinna (Eigenmann &amp;amp; Eigenmann, 1889) is described based on specimens collected in the Ibicuí-Mirim river, Rio Grande do Sul, Brazil, from April 2001 to March 2002. Diet description is based on the analysis of the frequency of occurrence and index of dietary importance of the ingested items. The monthly variation of stomach repletion, hepatosomatic and intestinal indexes was also analyzed. Major feeding activity occurred before (May, June and July 2001) the reproductive period, with the hepatosomatic index values showing similar variation along the year. Both the mean intestinal quotient and the analysis of the main ingested items (Bacillariophyta and Chlorophyta algae) indicate a detritivorous diet.

Variação de peso e sobrevida de Micrurus corallinus sob diferentes condições de alimentação em biotério (Serpentes, Elapidae)
Provedor de dados: 76
Autores: Serapicos,Eliana de Oliveira; Merusse,José Luiz Bernardino.
The weight variation in Micrurus corallinus (Merrem, 1820) during the first 60 days in laboratory animal rooms was very remarkable. This fact demonstrates the difficulty in adaptation of these animals to the captive environment. The weight loss was observed in animals under voluntary feeding as well as forced feeding. The survival rate was significantly higher in voluntarily fed animals. Sex differences were also observed with higher survival rates for males. Low survival rates were observed in both sexes under forced feeding.

Comportamento alimentar e dieta de serpentes, gêneros Boiruna e Clelia (Serpentes, Colubridae)
Provedor de dados: 76
Autores: Pinto,Carla da Costa; Lema,Thales de.
Boiruna maculata Boulenger, 1896 and Clelia rustica (Cope, 1878) were observed in captivity feeding snakes and rodents, respectively. Both species have shown a similar procedure in relation to the prey. Major behavior differences among the two species were: rodents killed before being swallowed, and snakes were mostly swallowed alive; both species are able to find the rodents head faster than the snake one; the coils formed during constriction were also used to hold the prey, specially the last coil, while swallowing rodents. Informations on stomach contents was gathered by dissection of preserved specimens of Clelia clelia (Daudin, 1803) and C. plumbea (Wied, 1820) were also included in the dietary study. The majority of preys consisted on snakes and...

Influence of quantities of brewer yeast on the performance of Anastrepha obliqua wild females (Diptera, Tephritidae)
Provedor de dados: 76
Autores: Cresoni-Pereira,Carla; Zucoloto,Fernando Sérgio.
Using artificial solid diets, experiments were performed with Anastrepha obliqua (Macquart, 1835) wild females in order to verify the influence of different quantities of brewer yeast on the performance and compensation behavior to unbalanced diets ingestion. The observed parameters were egg production, ingestion, diet efficiency and survival in the reproductive phase. Results indicated that there was no compensatory ingestion to different quantities of yeast and that the diet with 12.5g of yeast provided the best performance. The absence of compensatory ingestion is discussed based on the yeast phagostimulation and on the costs involved in solid diets ingestion. The relation between the analyzed parameters and the protein quantities in the diet were...

Provedor de dados: 14
Autores: ALMEIDA, I. M. de; RESENDE, E. K. de.
Foram analisadas as dietas dos peixes detritívoros da baía Tuiuiú, meandro abandonado do rio Paraguai, próximo a Corumbá, Mato Grosso do Sul. Os peixes detritívoros apresentam estratégias específicas para o consumo do detrito orgânico existente na baía, como o sairu-boi, Potamorhina squamoralevis, que possui os olhos voltados para baixo para consumo do detrito acumulado no fundo, e o cascudo, Liposarcus anisitsi, que se coloca de barriga para cima para raspar os detritos e algas acumuladas nas raízes das macrófitas aquáticas. Para L. anisitsi, que teve os conteúdos estomacais analisados em quase todos os períodos de amostragem, foi encontrada correlação entre índice alimentar e altura de inundação e transparência da água. Peixes detritívoros apresentam...

Autores: VOLPI, D.; ALVES, F. V.; SARAIVA, E. F.; VIGAS, V. P.; ARGUELHO, A. da S.; ZOPOLLATTO, M.; ALMEIDA, R. G. de.
A observação visual do comportamento ingestivo em ruminantes, principalmente naqueles mantidos em pastagens, apesar de comumente utilizada com diferentes finalidades de estudo, é trabalhosa, pouca precisa e empenha grande quantidade de mão-de-obra. Com o avanço da tecnologia em geral, outras metodologias, que fazem uso de sensores mecânicos, ópticos e sonoros, mostram grande potencial de uso em ruminantes. A bioacústica, em particular, adequa-se em experimentos que necessitam tanto de macro quanto de microatividades, otimizando mão-de-obra e com custo relativamente baixo em comparação à outras metodologias automatizadas. Entretanto, por ser um campo de estudo recente na produção animal, as operações de captura e análise dos sons ainda precisam ser...

Minimização do custo de produção como critério na formulação de dietas para bovinos de corte.
Provedor de dados: 14
Autores: BARIONI, L. G.; LANNA, D. P.; TEDESCHI, L. O.; VELOSO, R. F.
RESUMO: O critério de minimização do custo de matéria seca (MCMS) é frequentemente adotado para a formulação de dietas para animais. Esse critério, entretanto, possui limitações para bovinos, pois a solução aplica-se apenas a um nível de desempenho animal esperado, enquanto na prática, existem vários níveis de desempenho possíveis de serem implementados. Outro critério de formulação de dietas é o de minimização do custo direto de alimentação por quilo de carcaça (MCA). O uso desse critério possibilita ganhos econômicos, porém, apresenta limitações quanto à robustez da solução devido a sua natureza não linear, o que demanda uso de algoritmos menos eficientes e poucos robustos. Existe, portanto, demanda por métodos para a solução desse tipo de problema. Um...

Diel changes in acoustic and catch estimates of krill biomass
Provedor de dados: 5
Autores: Simard, Yvan; Sourisseau, Marc.
Krill-biomass estimates can be compromised by diel variabilities in acoustic backscatter and the catch efficiencies of various nets. This paper describes an effort to quantify these variabilities at fine temporal and spatial scales during a three-day experiment at a fixed location, using high-resolution, stratified Bioness samples and echo-integration, and assuming a fixed distribution of krill orientations. Night-time catches in the krill scattering layer (SL) were 15 times the acoustic estimates. The situation was reversed during daytime, when the acoustic estimates in the SL were 5 times larger than the catches. This collectively resulted in a ±10-dB gradual diel cycle in the difference of vertically integrated biomass from both sampling methods. Use of...

Microparticulate feeds for Penaeid larvae
Provedor de dados: 5
Autores: Kanazawa, A.
The mass production of penaeid larvae still depends on live foods such as diatoms, Chlorella and Artemia . However, it requires much facilities, maintenance expenses, and labor to produce a desired amount of life foods safely and constantly. Also, the nutritive value of planktonic organisms is occasionally variable and this makes the use of live food for mass culture restrictive. Therefore, it is necessary to develop microparticulate diets as a substitute for live foods to further increase the productivity of seed for shrimp culture.

Ecophysiologie de la reproduction chez l'huître creuse, Crassostrea gigas
Provedor de dados: 5
Autores: Pouvreau, Stephane; Lepennec, M.
The reproductive cycle of Megathura crenulata was documented and quantification of oocyte lipid reserves with lipo-specific stains was explored in both this species and in Crassostrea gigas. The necessity of providing food to female broodstock C. gigas in spring was re-evaluated, because subsequent larval and post-larval rearing performance was not affected by broodstock starvation during conditioning. Developmental study of the organs responsible of particle processing in C. gigas allowed the identification of critical stages related to the ontogenesis of each organ, as well as a better understanding of the evolution of these organs, highly-modified in the Ostreidae. Ciliary type identification and mucocyte mapping from post-larval to adult stage showed...

Variablility of stable isotope signatures (delta C-13 and delta N-15) in two spider crab populations (Maja brachydactyla) in Western Europe
Provedor de dados: 5
Autores: Bodin, Nathalie; Le Loch, Francois; Hily, Christian; Caisey, Xavier; Latrouite, Daniel; Le Guellec, Anne-marie.
The ontogenic variations of nitrogen and carbon stable isotopic signatures (delta N-15 and delta C-13) were investigated in two spider crab (Maja brachydactyla) populations inhabiting in different biotopes of Western Europe. The Iroise Sea population is localized in Western Brittany and characterized by a seasonal migration occurring on a large bathymetric and habitat gradient while the Seine Bay population, in the Eastern English Channel, remains in a more homogeneous environment during its migration. In the Iroise Sea population, delta C-13 Values increased significantly both with body size and age, revealing a shift towards "benthic-component" prey with spider crab growth. On the contrary, neither body size nor ageing gave rise to a significant trophic...

Influence of diet assemblage on Ostrea edulis broodstock conditioning and subsequent larval development
Provedor de dados: 5
Autores: Gonzalez, Ricardo; Mingant, Christian; Petton, Bruno; Robert, Rene.
In contrast with the Japanese oyster Crassostrea gigas and the Manila clam Ruditapes philippinarum, Ostrea edulis seed production in the hatchery has been reported to be erratic, with sudden and unexplained larval and post-metamorphosis mortalities. Fecundity and initial larval quality have been related to broodstock conditioning, but effects on larval development and metamorphosis remain poorly understood. In addition, molluscan larval mortalities have been often associated with bacterial contamination and flow-through techniques may help to overcome this problem. Both aspects have been considered in the present work. O. edulis broodstock were conditioned at 19 °C and fed three different microalgal diets. Two were single-species diets: Rhodomonas salina...

High prey-predator size ratios and unselective feeding in copepods: A seasonal comparison of five species with contrasting feeding modes
Provedor de dados: 5
Autores: Djeghri, Nicolas; Atkinson, Angus; Fileman, Elaine S.; Harmer, Rachel A.; Widdicombe, Claire E.; Mcevoy, Andrea J.; Cornwell, Louise; Mayor, Daniel J.
There has been an upsurge of interest in trait-based approaches to zooplankton, modelling the seasonal changes in the feeding modes of zooplankton in relation to phytoplankton traits such as size or motility. We examined this link at two English Channel plankton monitoring sites south of Plymouth (L4 and El). At L4 there was a general transition from diatoms in spring to motile microplankton in summer and autumn, but this was not mirrored in the succession of copepod feeding traits; for example the ambushing Oithona similis dominated during the spring diatom bloom. At nearby El we measured seasonality of food and grazers, finding strong variation between 2014 and 2015 but overall low mesozooplankton biomass (median 4.5 mg C m(-3)). We also made a seasonal...

The nutritional requirements of the Japanese shrimp Penaeus japonicus
Provedor de dados: 5
Autores: Guillaume, Julien.
Penaeus japonicus is probably the best known species among penaeids or even among shrimps. In juveniles, the protein requirement was best studied and Japanese shrimp appears as the most demanding penaeid species. They may be related to several factors such as energy level of the diet, digestibility or biological value of protein or other nutritional factors. The essential amino acids are well known, however from a quantitative point of view the requirements in each of these amino acids remain to be determined.

Impact on non target organisms of anti-marine wood-borer treatments. Evaluation of stress imposed by treatments on organisms from test sites
Provedor de dados: 5
Autores: Goulletquer, Philippe; Geairon, Philippe; Faury, Nicole; Razet, Daniel; Soletchnik, Patrick; Gras, Paul; Adessi, L.
In European waters, significant economic damages to wooden structures are caused by bivalves molluscs and crustaceans. Treatments like copper-chrome-arsenic mixtures (CCA) were designed to prevent settlement of these wood borer species. However, limited and conflicting evidence regarding the toxicity to non-target organisms are available in the literature. This report aims to provide insights regarding the CCA leachates' toxicity to an important aquaculture species, the blue mussel Mytilus edulis for which much information on normal and stressed physiology is available for purposes of comparisons. The mussels are usually considered as a particularly suitable species for biological monitoring (Smaal and Widdows, 1994). To address the CCA leachate issue, two...

Short term variations in feeding and metabolism of Acartia tonsa (pelagic copepod) in the Berre lagoon (France)
Provedor de dados: 5
Autores: Gaudy, R; Pagano, M; Cervetto, G; Saintjean, L; Verriopoulos, G; Beker, B.
Feeding, respiration, and ammonia excretion of Acartia tonsa were studied in a brackish lagoon, near Marseilles (Southern France). The experiments were performed during the same season in two successive years, using naturally occurring particles as food. Strong variations in both quantity and quality of food particles were recorded between the two series of experiments. The ingestion of particles according to their size was studied by means of the Coulter Counter technique. Females ingested more food than males. In both sexes, there was a tendency to select median to large particles, regardless of the shape of the particles-size spectrum. In 1990, the specific production rate, deduced from the energy budget, was equivalent to or greater than the observed...

Autores: Sauriau, P; Baud, Jean-pierre.
Based on Coulter Counter data, a new method is proposed to study the influence of the polymorphous variability in size as well as in shape of the diatom species Skeletonema costatum on the physiological performances of the Manila clam Ruditapes philippinarum . Three conditions are required in order to convert volumetric data determined with the Coulter Counter into metric data, i.e. (1) stability of the pervalvar diameter of the diatom chains, (2) statistical independence between length and pervalvar diameter of the diatom chains, and (3) negligible level of coincident passages through the aperture orifice. Under these three conditions, the mean length (l) of a S. costatum chain can be related to the mean pervalvar diameter (d) of diatom chains and to the...

Energy-protein management by some warmwater finfishes.
Provedor de dados: 5
Autores: Luguet, P; Moreau, Y.
If warmwater finfish protein requirements as level in diet is low, absolute intake per day is similar to those of coldwater species. But relation of this requirement with specific growth rate differs for strictly warmwater fishes as Tilapias. Analysis of partition between protein and non-protein energy retention shows that these species with Clarias make a better use of non-protein energy provided and consequently improve their protein retention. Better carbohydrate digestibility and metabolism are propounded as part of the explanation.

Modeling Japanese oyster physiological processes under natural tidal variation in suspended particulate matter
Provedor de dados: 5
Autores: Barille, Laurent; Prou, Jean.
Feeding and growth of the Japanese oyster Crassostrea gigas is simulated by a deterministic model. However, physiological processes, estimated by statistical relationships, have not been tested under extreme environmental conditions such as high level of suspended particulate matter. Ecophysiological experiments were therefore conducted in situ in the Bay of Marennes-Oléron during a spring and neap tide cycle in May 1991, to get a better representation of 2 important components of the energy budget of the Japanese oyster: clearance rate and selection efficiency. The relationships previously established by Raillard et al. (1993) are re-evaluated by integrating the action of high seston load, typical of tidal effect within estuaries, on the physiological...

Trophic ecology of large gadiforms in the food web of a continental shelf ecosystem
Provedor de dados: 5
Autores: Day, Louise; Kopp, Dorothee; Robert, Marianne; Le Bris, Hervé.
Human activities affect continental shelves, especially due to the harvest of living marine resources. Understanding their functioning and dynamics has become a growing concern in recent decades, especially through use of trophic modelling approaches. Studying the feeding ecology of key component species also improves this understanding by providing accurate information on trophic processes, particularly the dependence on trophic pathways. This study focuses on the trophic ecology of four large gadiforms (cod, haddock, whiting and hake) found on the continental shelf of the Celtic Sea. The study combines information on recently ingested prey (gut content analysis) and a more integrated indicator of food sources (stable isotope analysis). Two size classes...

Role de Sprattus sprattus (Linne, 1758) dans l'utilisation du zooplancton des eaux Roumaines de la Mer Noire
Provedor de dados: 5
Autores: Porumb, Loan I.
Feeding of the S. sprattus was studied comparatively with the dynamics of the zooplanktonic trophic base. In April, the sprat consumed 1,459 t of zooplankton, especially Acartia clausi (84 per cent). Zooplanktonic productivity was 30 per cent due to Acartia clausi, and the sprat consumed 56 per cent of this copepod production. In April, the wt growth of the sprat was 115 t. In May, the sprat consumed 6.201 t of zooplankton, that resulted in a fish production of 492 t. A clausi contributed 36.41 per cent to the zooplankton production and the sprat fed on copepods at a level of 93 per cent. In June, only 1,094 t of zooplankton resulted in a fish production of 87 t. Zooplanktonic production was 60 per cent due to A. clausi, and only 12 per cent of this was...

Experiments were canied out to assess the copper-chrome-arsenic (CCA) trealment effeets on the Blue mussel Mytilus edulis physiology. Experimental design included two complementary approaches: 1) scope for growth esrimates based upon the energy balance between respiration energy loss and energy gained from feeding processes. 2) a biological early waming system for valve behavior monitoring under CCA exposures. Various temperature range (seasonal effeet). physiological status (mature &amp; immature mussels) as weil as CCA concentrations (from 0 to 48kg/m3) and rime exposure were tested. Significant monality rates for the experimental mussel populations were recorded in alI experimental modalities but the 2kg/m3 CCA treatment concentration. Overall results...

Alimentation expérimentale de l'huître Crassostrea gigas à l'aide de navicules bleus Haslea ostrearia (Simonsen) de différentes tailles
Provedor de dados: 5
Autores: Barille, Laurent; Bougrier, Serge; Geairon, Philippe; Robert, Jean-michel.
The influence on the feeding physiology (clearance, filtration, ingestion, absorption) of the Japanese oyster Crassostrea gigas of low concentrations of suspended particulate matter (SPM ranging from 2 to 20 mg.l-l) and high food quality (mean organic fraction =54 %) was studied in the laboratory. Experimental diets were made up with three strains of the "blue diatom" Haslea ostrearia, which is responsible of the greening of oyster-ponds. The strains were characterized by different sizes (48, 65 and 98 µm respectively) but possessed the same density and biochemical composition. Clearance rate was found constant at 2.2 1.h(-l).g-l dry weight and therefore was not influenced by increasing seston load. Pseudofaeces production was observed for SPM...

Influence de l'hydrodynamique des bassins sur la survie et la croissance des larves de turbot (Psetta maxima)
Provedor de dados: 5
Autores: Gaignon, Jean-louis; Petton, Bruno; Quemener, Loic.
During larval rearing phase of turbot, a substantial variability in survival and growth is frequently observed. In this paper, we studied the effects of hydrodynamics in larvae rearing tanks on the survival and the growth of fed and starved larvae, using the following conditions: water flows of 600 and 1200 ml.mn(-1), constant and progressive ones, air flows of 10 and 30 ml.mn(-1), downward and upward water circulation, with direction change during the rearing phase. We also studied the interactions between water circulation direction and feeding conditions by (1) shifting the first feeding day (4 occasions, at 8 hours intervals, from 52 to 76 hours after 95% of hatching) and (2) using 2 amounts of preys (which differ by a factor 3). The results show that...

Comparaison de cinq indices alimentaires utilises dans l'analyse des contenus stomacaux
Provedor de dados: 5
Autores: Rosecchi, E; Nouaze, Y.
Compound indices are often used in the analysis of fish stomach contents to characterize diet. Five of these indices, combining two or three measures of prey importance: weight, abundance and frequency of occurrence, are mathematically compared in this work. Data from a feeding study of sparid fish show that different indices can produce different results. Four classifications of food, in terms of preferences, are applied to Sparidae, compared and discussed. A new method of classifying the prey of fish into groups is proposed. It characterizes the main items in the diet, whatever feeding index is chosen for the analysis.

Potential feeding and spawning habitats of Atlantic bluefin tuna in the Mediterranean Sea
Provedor de dados: 5
Autores: Druon, Jean-noel; Fromentin, Jean-marc; Aulanier, Florian; Heikkonen, Jukka.
Atlantic bluefin tuna Thunnus thynnus (ABFT) is a fish of high market value which has recently become strongly overexploited, notably in the Mediterranean Sea. This area is an essential habitat for ABFT reproduction and growth. We present here an approach for deriving the daily mapping of potential ABFT feeding and spawning habitats based on satellite-derived sea surface temperature (SST) and chl a concentration. The feeding habitat was mainly derived from the simultaneous occurrence of oceanic fronts of temperature and chl a content while the spawning habitat was mostly inferred from the heating of surface waters. Generally, higher chl a contents were found to be preferred for the feeding habitat and a minimum SST value was found for the spawning habitat....

Review of grow-out techniques under tropical conditions: Experience of Thailand on seabass (Lates calcarifer ) and grouper (Epinephelus malabaricus)
Provedor de dados: 5
Autores: Tookwinas, S.
Seabass and grouper have been reared in cages in coastal waters in Thailand for 10 years. The fingerlings are nursed for a month in nylon nursing cages. Then, the juvenile fish are reared in culture cages which can be stationary or floating. The cage is usually 5 x 5 x 2 metres. The stocking density is around 500 to 2000 fish per cage. The survival rate is approximately 80%. The selling price at the culture site is 80 baht and 250 baht per kg for sea bass and grouper respectively. The culture method and economics of culture are explained.

Alimentation du merlan Merlangius merlangus L. en Mer Celtique
Provedor de dados: 5
Autores: Du Buit, Marie-henriette; Merlina, Frédéric.
The importance of predation by the whiting (Merlangius merlangus ) from the Celtic Sea has been studied by analysis of stomach contents. Eight hundred and thirteen whitings have been examined during 1984-1986 period. Fish food totalizes 97% of food. It is chiefly a swimming species: no cannibalism has been observed. The daily food index varies between 2 and 4% according to the length and the annual consumption on fishes of nominal catches (11230 t for 1983) would reach 135,000 t corresponding to species already fished for human consumption and the fish meal industry.

Bases biologiques de la production de deux Mollusques d'intérêt économique: reproduction chez Megathura crenulata, reproduction et développement chez Crassostrea gigas
Provedor de dados: 5
Autores: Cannuel, Rozenn.
The reproductive cycle of Megathura crenulata was documented and quantification of oocyte lipid reserves with lipo-specific stains was explored in both this species and in Crassostrea gigas.  The necessity of providing food to female broodstock C. gigas in spring was re-evaluated, because subsequent larval and post-larval rearing performance was not affected by broodstock starvation during conditioning.  Developmental study of the organs responsible of particle processing in C. gigas allowed the identification of critical stages related to the ontogenesis of each organ, as well as a better understanding of the evolution of these organs, highly-modified in the Ostreidae. Ciliary type identification and mucocyte mapping from post-larval to adult stage showed...

Growth, feeding and distribution of the solenette Buglossidium luteum with particular reference to its habitat preference
Provedor de dados: 5
Autores: Amara, Rachid; Mahe, K; Le Pape, Olivier; Desroy, N.
Growth, condition, diet and spatial distribution of the solenette Buglossidium luteum (Risso, 1810) were investigated along the coasts of the French Atlantic, eastern English Channel and Southern Bight of the North Sea. Distribution and habitat preferences of solenette were analysed in relation to physical and biological features presumed to influence fish distribution. B. luteum was patchily distributed and concentrated in shallow muddy and muddy-sand bottoms moderately influenced by estuarine waters (euhaline waters). In the studied area, solenette seemed to find habitats suitable for growth. Food availability was not assumed to be a limiting factor for solenette distribution in contrast to abiotic factors such as salinity.

L'aquaculture des crevettes, role de la nutrition
Provedor de dados: 5
Autores: Guillaume, Julien.
Shrimp and prawn aquaculture is developing fast and amounts presently to 8% of world consumption. It concerns mainly various species of penaeids and is done with different techniques where feeding plays a variable role. This role is discussed both in the case of more or less extensive farming and in the case of intensive farming. The lack of knowledge in the field of nutrition itself is emphasized as well as the importance of feed technology both for juvenile foods and larval microcapsules or microparticles.

Interactions entre comportement et variations de la croissance des juvéniles de la sole (Solea solea) dans les nourriceries des pertuis Charentais
Provedor de dados: 5
Autores: Laffargue, Pascal.
This thesis aimed to identify and analyse processes involved in the functioning of sole Solea solea (L.) nurseries in the Pertuis Charentais, the most important oyster cultivation basin in Europe and a major nursery for the Bay of Biscay sole. Juveniles concentrate in coastal and estuarine habitats, which are essential in the biological cycle of this species but implies (i) adaptation to environmental variability and (ii), accessibility to habitat resources. Assuming that effective nurseries account for what fish must perform in response to habitat constraints, especially in selecting feeding, resting or refuge areas, we used both field works and mesocosm experiments to obtain integrative indicators of the nursery quality (growth rate, Fulton's condition...

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives
Provedor de dados: 5
Autores: Person, L.
Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

Variations of zooplankton metabolism and feeding in the frontal area of the Alboran Sea (western Mediterranean) in winter
Provedor de dados: 5
Autores: Gaudy, R; Youssara, F.
Respiration, excretion (NH4 and PO4) and feeding of zooplankton from the upper 200 m of the Almeria-Oran frontal region (western Mediterranean), were studied during winter 1997. Eight sites belonging to the three main hydrodynamic structures of the area (Mediterranean water, geostrophic Atlantic jet and associated anticyclonic gyre) were considered. Lowest values of respiration, PO4 excretion, O/P atomic ratio and particle ingestion were found in Mediterranean waters. At the frontal limit, respiration and ammonium excretion were enhanced compared to the adjacent structures (Mediterranean water and Atlantic jet). In the gyre water, lowest O/N and highest N/P values were observed and maximum faecal pellet production and reproduction activity (inferred from...

The objective of this study was to identify a possible effect of food on the acceleration of decontamination in blue mussels, Mytilus edulis, containing diarrhetic toxins belonging to the okadaic acid (OA) structural group. An experimental protocol was designed to describe and compare the decontamination kinetics and detoxification rates of naturally OA-contaminated mussels that had either received or not received food for three weeks. The protocol was applied in two trials (in June 2006 and June 2007, called Ker06 and Ker07), conducted one year apart on samples of mussels collected in the same area, at the same season. Okadaic acid (OA), the main lipophilic toxin produced by the toxic alga Dinophysis acuminata, was analysed over the course of the...

Bivalve genomics
Provedor de dados: 5
Autores: Saavedra, Carlos; Bachere, Evelyne.
Interest in bivalve genomics has emerged during the last decade, owing to the importance of these organisms in aquaculture and fisheries and to their role in marine environmental science. Knowledge of bivalve genome structure, function and evolution resulting from 20th century "single gene" approaches is limited, but genomic technologies are called to dramatically increase it. Research based on linkage maps, transcriptomics and proteomics is being carried out to study the genetic and molecular bases of traits of interest in bivalve farming industry, mainly disease susceptibility, tolerance to environmental stress, and growth. The Pacific oyster (Crassostrea gigas) is now the focus of an international genome-sequencing consortium. The use of bivalves in...

Effects of nutritional requirement of live food organisms on growth and survival of barramundi/seabass Lates calcarifer (Bloch) larvae.
Provedor de dados: 5
Autores: Rimmer, M; Reed, A.
Larvae of barramundi (Lates calcarifer ) reared intensively in some Australian hatcheries have suffered periodic high mortalities which have been ascribed to nutritional deficiencies in the live food organisms used, particularly deficiencies of polyunsaturated fatty acids. Barramundi larvae reared in an experimental system and fed on four diets, representing combinations of supplemented and unsupplemented rotifers (Brachionus plicatilis ) and supplemented and unsupplemented brine shrimp (Artemia salina ). Supplementation of rotifers and brine shrimp with a commercially available microencapsulated diet increased the levels of several polyunsaturated fatty acids in the food organisms.

Effects of temperature on growth and metabolism in a Mediterranean population of European sea bass, Dicentrarchus labrax
Provedor de dados: 5
Autores: Person, Jeannine; Mahe, Kelig; Le Bayon, Nicolas; Le Delliou, Herve.
Growth and metabolism of juvenile European sea bass of a Western Mediterranean population were assessed at six constant temperatures (13, 16, 19, 22, 25 or 29 degreesC) in an 84-day trial. Duplicated groups of 84 fish (initial weight 80 I g) were held under O-2-concentrations close to saturation (87 mg l(-1)) and were fed to satiation. Mass gain increased as temperature increased from 13 to 25 degreesC. At 25 and 29 degreesC, growth was similar up to day 72, but a 6% decrease was observed by day 84 at 29 degreesC. Days 0-84 specific growth rates (SGR) were 0.45%,1.29% and 1.21% day(-1) at 13, 25 and 29 degreesC, respectively.

Within the framework of an investigation into the carrying capacity of the Bay of Marennes-Oléron (France) for bivalve culture, the in situ uptake of suspended particulate material by oysters (Crassostrea gigas) and mussels (Mytilus edulis) was determined in experiments with benthic ecosystem tunnels. Very high fluctuations in seston quantity and quality were observed within and between tidal cycles. The percentage of organic carbon was inversely related to seston quantity at low concentrations. Organic carbon was diluted by resuspension of material rich in inorganic matter. At high seston concentrations a constant level of about 2% organic carbon was found. The CIN ratio was relatively constant throughout the seasons and fairly low (6.5 to 8.4). Owing to...

Autores: Cherubini,A. L.; Barrella,T. H.; Silva,R. J. da.
The objective of this paper is to report the death of a Boa constrictor amarali after ingestion of a tree porcupine. The animal was donated to the Center for the Study of Venoms and Venomous Animals (CEVAP/UNESP) - and died in captivity. At necropsy, spine-like structures were observed in the stomach serosa and vicinity, and the stomach mucosa showed an intense reddish area, suggesting inflammation. The analysis of the spine-like structure revealed that they were tree porcupine spines. The feeding habits and inexperience of this Boa constrictor amarali in selecting its prey may have been be responsible for its death.

A new short-rostrum odontocete (Mammalia: Cetacea) from the middle Miocene of the Eastern Netherlands
Provedor de dados: 16
Autores: Bianucci, G.; Landini, W.
An incomplete odontocete (Mammalia, Cetacea) skull from Middle Miocene Miste Bed (near Winterswijk in the eastern part of The Netherlands) is described as Vanbreenia trigonia, a new genus and species. The skull exhibits a short rostrum with only two maxillary teeth for each toothrow and with narrow and toothless apical portion exclusively formed by the premaxilla. Considering this last character, the specimen could belong to the Eurhinodelphinidae even if a certain attribution is not possible because of the incompleteness of the specimen. Vanbreenia n. gen. could represent a specialized adaptation to bottom suction feeding among the eurhinodelphinids.

The snake-eyed skink Ablepharus kitaibelii is one of the smallest European lizards, but despite its minute size it is able to feed on comparatively large prey. Here we investigate the diet of A. kitaibelii and the mechanisms that allow the skink to overpower relatively large and even noxious prey. High-speed cinematography showed that A. kitaibelii uses a series of shaking and battering movements to immobilise and kill prey prior to swallowing. During this process, the skinks rises up on the hind limbs and then whacks the prey sidewise on the substrate by twisting the trunk, neck and head laterally. Our analysis showed that the shaking kinematics is very uniform among the investigated specimens. The morphological investigation of the cranio-cervical system...

Autores: Hartog, J.C. den; Ocaña, O.; Brito, A.
Species of Corallimorpharia collected during the CANCAP expeditions in the south-eastern part of the North Atlantic are described and discussed, altogether five species belonging to three genera of Corallimorphidae: the shallow water forms Corynactis viridis Allman, 1846, Pseudocorynactis caribbeorum den Hartog, 1980, and P. caboverdensis spec. nov., and the deep-sea forms Corallimorphus cf. atlanticus Carlgren, 1934, and C. ingens Gravier, 1918. The taxonomic status of the representatives of the genus Corynactis Allman, 1846, is discussed. All temperate to subtropical species described so far belong to a group of closely related allopatric taxa forming the Corynactis viridis-complex, possibly representing a single species only. The colours of Corynactis...

Cassiopea frondosa and C. xamachana are carnivorous. Prey are filtered from the water by the pumping activity of the umbrella. Prey, predominantly small epibenthic crustaceans (0.2- 10 mm in length) are caught mostly by interception. However, some prey may impact on the oral surface through turbulence or by their own locomotion. Prey capture was essentially the same for both species, except that the vesicles take an active part in prey capture only in C. frondosa. Ingestion occurred after the digitate-fringed lips of the funnel-shaped oral ostia opened. The digitata...

Autores: Medeiros,Lenice; Megier,Gabriela A.
The Neotropical brown stink bug Euschistus heros (F.) can reach high densities in some soybean areas in Brazil. Besides soybean, it also feeds on other plants, but little is known on the alternative hosts of E. heros in Rio Grande do Sul state. In this study, wild non-cultivated hosts of E. heros at Norwest of Rio Grande do Sul state were determined, and the E. heros performance was compared when fed on soybean and on wild hosts. Bugs were sought in plants located inside and on the edge of soybean fields during 2004/2005 and 2005/2006 seasons. Adults were recorded feeding on seeds of Amaranthus retroflexus (Amaranthaceae), and on fruits of three Solanaceae, mainly Vassobia breviflora. Immature survivorship on soybean (86.7%) and on V. breviflora (81.8%)...

ABSTRACT The main goal of this research was to investigate the differences in diet composition among three species of the genus Lutjanus inhabiting a coastal lagoon as juveniles. The working hypothesis was that these species feed on a common base of food resources and therefore, some niche overlap is present in terms of general diet composition. However, changes in the trophic niche with size and differences in some morphological traits among species explain observed differences in diet. Fish were collected during 42 sampling trips conducted regularly from February 2011 to January 2012 using several types of fishing gear. Total number of analyzed stomachs was 288 for Lutjanus argentiventris from 2.3 to 19.9 cm total length (TL); 178 for Lutjanus colorado...

Autores: Soares,Bruno E.; Rosa,Daniela C. O.; Silva,Nathália C. S.; Albrecht,Miriam P.; Caramaschi,Érica P.
ABSTRACT Fishes of the order Gymnotiformes have high diversity of oral and head morphology, which suggests trophic specializations within each clade. The aim of this study was to describe resource use patterns by two fish species (Gymnorhamphichthys rondoni and Gymnotus coropinae) in the National Forest Saracá-Taquera, Oriximiná - Pará, analyzing microhabitat use, diet composition, feeding strategies, niche breadth and niche overlap. Stomach contents of 101 individuals (41 G. rondoni and 60 G. coropinae), sampled in 23 headwater streams were analyzed and volume of food items was quantified to characterize their feeding ecology. Gymnorhamphichthys rondoni was captured mainly on sandy bottoms, whereas G. coropinae in crevices. Both species had a...

Autores: Fráguas,Patrícia Santos; Pompeu,Paulo Santos.
ABSTRACT Dams often cause drastic changes in freshwater environments and can compromise the quality and availability of food resources in rivers. This study aims to analyze the influence of a dam on the trophic structure of fish assemblages in lotic areas located both upstream and downstream of the Irapé Hydroelectric Power Plant. Fish sampling occurred before (2003 to 2005) and after (2011 to 2017) the impoundment, which began in 2006. The trophic structure and species composition before dam construction were similar upstream of the reservoir and downstream of the dam. After the building of the dam, both aspects of the assemblages changed along the lotic stretches - the upstream incurred an increase in biomass of detritivores and a decrease of piscivores...

Diet of two serrasalmin species, Pygocentrus piraya and Serrasalmus brandtii (Teleostei: Characidae), along a stretch of the rio de Contas, Bahia, Brazil
Provedor de dados: 83
Autores: Trindade,Márcia Emília de Jesus; Jucá-Chagas,Ricardo.
Serrasalmus brandtii and Pygocentrus piraya are two common piranha species in the Barragem da Pedra Reservoir, rio de Contas. In order to identify the diet composition of the two species, monthly collections were performed at three sites between May 2001 and April 2003, using two gill nets of different mesh sizes cast at the beginning of the day and visited after 6, 12 and 24 h. The qualitative composition of the diet was analyzed by determining the frequency of occurrence. Comparison of the two species showed a higher relative abundance of S. brandtii (151) compared to P. piraya (55). The food items most frequently found in the stomachs of the two species were fins, fish and shrimp. Serrasalmus brandtii showed a greater feeding plasticity than P. piraya.

Early morphological variation and induction of phenotypic plasticity in Patagonian pejerrey
Provedor de dados: 83
Autores: Crichigno,Sonia A.; Battini,Miguel A.; Cussac,Víctor E.
The aim of this work was to study two aspects of phenotypic plasticity in the Patagonian pejerrey Odontesthes hatcheri (Teleostei: Atherinopsidae) the dependence of the early morphology on developmental time and temperature, and the induction of morphological changes by controlled feeding in juveniles. Newly hatched free embryos, incubated at two different temperatures (13 and 18oC), and juveniles were used for the study and induction of phenotypic plasticity. Body and head shapes were analyzed with geometric morphometrics and linear measurements. Our results showed that shape variation at hatching was related to the bending of the embryo head on the yolk sac, increasing the head-trunk angle due to progressive straightening of the embryo. The head-trunk...

Provedor de dados: 83
Autores: Benone,Naraiana Loureiro; Lobato,Cleonice Maria Cardoso; Soares,Bruno Eleres; Montag,Luciano Fogaça de Assis.
ABSTRACT Spatial and temporal variations in streams promote large fluctuations of resource availability, thus affecting the diet of fishes. We evaluated the effects of hydrological periods and stream order within periods on the diet of the flag tetra Hyphessobrycon heterorhabdus. We analyzed 160 stomachs in eight streams ranging from 1st to 3rd order between dry and flood period. Sampled streams belonged to a well-preserved area in the Eastern Amazon. The flag tetra is omnivorous, with a tendency towards insectivory. During the dry period, the species exhibited a higher amount of autochthonous than allochthonous items. Fish consumed more allochthonous items in 1st and 2nd order streams in the dry period and in 1st and 3rd order streams in the flood period....

Provedor de dados: 83
Autores: Novakowski,Gisele C.; Cassemiro,Fernanda A. S.; Hahn,Norma S.
ABSTRACT Relationship between diet and morphology of cichlid were analyzed considering that the trophic apparatus determines differential food use among species. Cichlasoma dimerus and Satanoperca pappaterra showed a generalist diet, while Chaetobranchopsis australis and Crenicichla vittata consumed zooplankton and fish, respectively. Significant correlation between morphology and diet was not found, but C. australis differed from the others species in the upper mouth and longer gill rakers. The morphology data and food size segregated the cichlids into three groups. The first was comprised by C. australis, which has many and longer gill rakers and a more protractile mouth, the second by C. vittata, which have a larger and more-protruded mouth and the...

ABSTRACT We tested whether interindividual variations in diet composition within a population of Deuterodon stigmaturus can be explained by morphological differences between individuals, and whether diet-morphology relationships are dependent on the ontogenetic development. We analyzed diet of 75 specimens sampled in a coastal stream of Southern Brazil. Variation in stomach content was summarized with a Principal Coordinate Analysis (PCoA). The retained PCoA axes were tested as response to standard length (SL), and to values of intestine length (IL) and mouth length (ML) independent of body size, using linear mixed-effects models (LMM). The most consumed food items by D. stigmaturus were filamentous algae (41%), terrestrial plants (20.3%), detritus (12%),...

Comparison of growth and exploratory behavior in mice fed an exclusively milk formula diet and mice fed a food-pellet diet post weaning
Provedor de dados: 19
Autores: Ishii, Toshiaki; Ito, Takuya; Nishimura, Masakazu; 石井, 利明.
An exclusively milk formula diet stunted the growth of mice immediately following weaning. Milk-fed mice displayed a low-frequency profile of exploratory behavior, while pellet-fed mice showed high-frequency exploration. In contrast to exploratory behavior, feeding behavior did not differ significantly between milk- and pellet-fed mice. Despite showing low-frequency exploratory behavior, mice on an exclusively milk formula diet showed no difference in behavioral activities analyzed by an automatic hole-board apparatus compared to pellet-fed mice. These results suggest that the growth stunt caused by an exclusively milk formula diet retards the acquisition of active exploratory behavior without affecting the emotional state of mice.

Autores: Ishii, Toshiaki; Furuoka, Hidefumi; Ito, Takuya; Kitamura, Nobuo; Nishimura, Masakazu.
The mesencephalic trigeminal nucleus (Me5), which receives input from oral proprioceptors and projects to higher brain regions, is involved in mastication-induced modulation of satiation. To investigate how the Me5 is involved in the control of feeding and exploratory behavior, we examined the effect of bilateral electrolytic lesions of the Me5 on feeding and exploratory behavior in mice. Mouse feeding and exploratory behaviors were analyzed using a food- search-compulsion-apparatus (FSCA), which was designed to distinguish between the two behaviors under standard living conditions. To assess anxiety in mice in an unfamiliar environment, exploratory activity was analyzed in an automated hole-board apparatus. Mice with bilateral Me5 lesions had unique...

Exploitation et optimisation de la production des cystes du crustacé "Artemia tunisiana" (bowen et sterling, 1978) dans la saline de Sfax
Provedor de dados: 20
Autores: Aloui, N.; Amorri, M.
La saline de Sfax constitue le meilleur site pour l’exploitation et la production d’Artemia en Tunisie. La production de cystes est exploitée chaque année pour être utilisée dans l’alimentation des larves de poissons. Cette production est estimée à 30 kg de cystes poids sec. Toutefois, lors de nos campagnes de récolte, nous avons enregistré de grandes pertes de cystes occasionnées par les vents emportant les cystes qui seront mélangés avec le sable.    Afin de minimiser les pertes et optimiser la production naturelle de la saline, nous avons jugé utile, d’installer des barrages dans les coins des bassins à Artemia pour s’opposer à l’action du vent. Par ailleurs, nous avons fait un suivi mensuel de l’abondance des cystes récoltés et de quelques paramètres...

The objective of this study was to evaluate five half-moist diets with graded levels of chemical fish silage (40, 50, 60, 70 and 80 %) prepared with 2 % sulfuric acid 98 % (weigth/volumen), as a unique animal protein source. They were compared with a commercial food (20 % of fish meal), Clarias gariepinus feeding during 60 days. The experimental design was completely randomized and the statistical analysis of the results was done through analysis of variance and the results were compared through the Duncan test at 5 %. The results showed that indicators such as: growth, feed utilization and survival rate did not differ significantly (p &gt; 0,05) between experiment diets, representing between $188,00 and 302, 00 USD/t saving at fingerling.

Consideraciones sobre la alimentación de la caballa con especial enfasis en la depredación de huevos y larvas de peces
Provedor de dados: 20
Autores: Pájaro, M.
Adult and juvenile fish inter and intraspecific predation may be an important source on these first development stages. In this work, adult and juvenile mackerel samples from two areas of Buenos Aires province, one south of Cape San Antonio and the other near Mar del Plata city were analyzed. An important anchovy postlarvae ingestion in both regions considered was observed. A high number of mackerel eggs in the stomach contents from adults was identified. This evidence of cannibalistic behaviour in the argentine mackerel is the first of its kind made in this species and allows to suggest that embryo mortality due to cannibalism might constitute and important percentage of the total embryonic mortality.

Autores: Sánchez, M.F.; Prenski, L.B.
This work is a first approach in the study of the trophic ecology from a multispecific fishery in San Jorge Gulf (45°-47°S), Argentina. Stomach contents from 28 demersal fish species were analyzed. Taxonomic and trophic spectrum were obtained. Using weight percentage of each prey, trophic spectrum variations for size classes were analized for each of the 12 considered "dominant" species. Overlaping in the diet among these predators was estimate using cluster analysis. There was an interespecific diet overlap between juveniles belonging to demersal-benthic fish species, because all of them prey upon Stomatopoda and Munida. Adults from those species and hake prefered young and adult hake as preys, while Macruronus magellanicus and juvelines Merluccius hubbsi...

Results of the inclusion of GICABU and torula yeast in the diet for the Caribbean white shrimp (Litopenaeus schmitti) juveniles and cachaza oil in postlarvae diet are presented. Three completely randomised experimental designs were carried out to evaluate practical and semipurified diets, in juveniles and postlarvae respectively, with different by-products inclusion levels. Food was accepted and consumed in all the experiments. Shrimps reached a significantly higher growth (P&lt;0.05) when torula yeast was included at 15, 20 and 25 % in diet, thus demonstrating the feasibility of the partial fish meal substitution. No significant differences were found (P&gt;0.05) when GICABU was included up to 10 % in juvenile diet. Total replacement of sunflower oil by...

Autores: Rincón-Díaz, M.P.; Rodríguez-Zárate, C.J.
The San Bernardo Archipelago, in the Colombian Caribbean zone, is well recognized for being a sporadic nesting and feeding area for the green, hawksbill and loggerhead turtles. Due to the fact that the San Bernardo Archipelago has outstanding coral areas, marine grasses and sandy beaches and their environmental offers for the marine turtles have not been described yet, it was opportune to carry out this study between July and October of 2002. Thus, this research tends to fill this gap by describing the nesting beaches and feeding areas according to their geomorphologic and biotic aspects and, for the later areas, some oceanographic aspects too. Seven potential nesting beaches and 20 stations on feeding areas were evaluated to identify natural and...

Autores: Sánchez, R.P.; de Ciechomski, J.D.; Lasta, C.A.; Guerrero, R.A.
Lagrangian changes in distribution and survival within an anchovy egg and larvae patch were studied by means of multiple opening/closing sampling following a free drifting buoy. The buoy was equipped with a radar reflector and flashing light, and it was connected to a current cross drogue floating at 15 m depth, which corresponded to the main egg and larvae concentration within the patch. The drifter was launched on the Buenos Aires continental shelf, off Necochea during the spring spawning peak of 1983. Three discrete depths (within, below and above the thermocline)were repeatedly sampled close to the drogue with a Motoda sampler. Egg and larval abundances in the vicinity of the drogue were monitored at 3/4 hour intervals for a period of three days. Each...

Autores: Aristizabal, E.O.; Suárez, J.
The red porgy (Pagrus pagrus)is an important commercial and recreational species with very good prospect for aquaculture. Because significant mortalities, the mass production of this species is limited. This paper describes three weaning strategies to investigate their effects on the survival and growth of red porgy larvae reared in laboratory: A)traditional three-step weaning (rotifers - Artemia - diet)(control); B)one-step early weaning by co-feeding (rotifers - Artemia + diet), and C)one-step direct early weaning (rotifers - diet). Sigificative differences were recorded among treatments (P0.05). Best survival rate (45.6 ± 7.6 percent)and growth (7.4 ± 0.5 mm)were found in treatment B. Results indicate that co-feeding red porgy larvae with inert and live...

On the base of samples of congrid eels captured in the South Western Atlantic Ocean, between 34 degree S to 40 degree S and 30m to 400m depth, from research cruises, commercial fleet (low scale and coastal fishing) and specimens preserved in ichthyological collections, four species were determined: Ariosoma opistophthalmum, Conger orbignyanus, Bassanago albescens and Bassanago nielseni. The latter is the first record in the region. Diagnosis of taxa from Family Congridae to species is given. Morphology, reproduction, feeding and distribution of the fish species found from the region are compared and discussed, as well as those from other parts of the world. On the other hand, numerous samples of ichthyoplankton were obtained from research cruises carried...

Autores: Koen Alonso, M.
The comparative analysis of the food habits between top predator allows the evaluation of how these species use the trophic resources. They also make possible the study of potentially competitive relationships and the role of these predators in the regulation and structure of the community. The marine community of northern and central Patagonia is structured on the tri-trophic system composed by the Argentine anchovy (Engraulis anchoita), the Argentine shortfin squid (Illex argentinus), and Argentine hake (Merluccius hubbsi). Several marine mammals and elasmobranchs use these species as food resources. For this reason, the objective of this work was to analyze comparatively the diet of the South American sea lion (Otaria flavescens), the dusky dolphin...

An assessment survey on the austral fish was carried out during the summer 1997 on both the shelf and slope off southern Argentina. The cruise covered 101,508 nm2 between 45° and 54° 30'S and depths between 50 and 400 m. The survey did not include the area controlled by the United Kingdom. Considering the total area as an undivided stratum, a random sampling was used to estimate demersal fish biomass and a delta distribution-based model to evaluate mean densities. Out of the forty five species caught 28 were bony fish and 17 elasmobranch. Four cephalopod mollusc species were also identified. A biomass of 3.2 million tons (CI(95o/o): 1.90 - 6.06 millions) proved that longtail hake was the most abundant resource within the region followed by common hake...

The high cost of using live microalgae and the variations in nutritional value during larval culture constitute a problem for any operation relying on the massive culture of unicellular microalgae. The price of Artemia cysts in the international market and the increasing demand in Cuba, due to the development of the shrimp culture industry, has made the search of feeding alternatives that can of satisfactory diminish the live food consumption in shrimp larviculture, essential. Spirulina platensis meal (SPM), produced commercially in Cuba, has optimal nutritional characteristics to be used as a food ingredient in any aquatic animal culture.  For that reason in this thesis we set out to improve the efficiency in the production of Litopenaeus schmitti shrimp...

Studies of the life-history and energetics of marine and brackish-water nematodes: 2. Production, respiration and food uptake by &lt;i&gt;Monhystera disjuncta&lt;/i&gt;
Provedor de dados: 27
Autores: Herman, P.M.J.; Vranken, G.
An energy budget was constructed for the marine nematode &lt;i&gt;Monhystera disjuncta&lt;/i&gt;. Respiration was measured with a modified Cartesian diver technique, in which the nematodes were kept in agar inside the diver 'head'. The relationship between respiration and body weight was: R=1.53 W&lt;sup&gt;0.75&lt;/sup&gt;. Body growth was exponential during the juvenile phase, with a growth rate equal to 0.61 d&lt;sup&gt;-1&lt;/sup&gt;. After maturation the growth rate fell to 0,17 d&lt;sup&gt;-1&lt;/sup&gt;. Food uptake was measured in experiments with radiolabeled bacteria. In one series of experiments the accumulation of radiolabel in the nematodes was followed. In a second series the decrease in labeling was followed when pre-labeled nematodes fed on...

Studies of the life-history and energetics of marine and brackish-water nematodes: 1. Demography of &lt;i&gt;Monhystera disjuncta&lt;/i&gt; at different temperature and feeding conditions
Provedor de dados: 27
Autores: Vranken, G.; Herman, P.M.J.; Heip, C.H.R.
Aspects of the demography of &lt;i&gt;Monhystera disjuncta&lt;/i&gt; were investigated at different feeding conditions (monoxenic cultures with different bacterial strains, and different densities in the feeding suspension with one strain). Embryonic development time, minimum generation time, egg deposition rate and adult longevity depend on temperature, quality and quantity of food offered. Body mass at maturity is an allometric function of food density. It is shown that a previously inferred selectivity in food uptake is an artifact of culture conditions. pH buffering and addition of sterols permit culture of the species on a wide variety of bacterial strains. &lt;i&gt;M. disjuncta&lt;/i&gt; is less well adapted to take advantage of high food density...

Optimal Contracting for Cattle Feeding: An Assessment of Climatic Conditions
Provedor de dados: 31
Autores: Rahman,   Shaikh Mahfuzur.
A unique approach using a biophysical growth model from the animal science literature is used to examine optimal contract cattle feeding behavior under alternative climatic conditions. The examination of incentives and outcomes in an unusually comprehensive contract parameter and behavioral space is made possible by combining simulated feedlot and carcass performance of a large set of cattle with public price and weather data.  The model uniquely fits typical risk aversion levels and rationalizes existing contract types. The results show that optimal cattle feeding contract varies with climatic condition, but there is a tendency to replace cost-of-gain contracts with yardage-feed contracts as grid pricing has emerged.

Use of food resources and resource partitioning among five syntopic species of Hypostomus (Teleostei: Loricariidae) in an Atlantic Forest river in southern Brazil
Provedor de dados: 103
Autores: Abilhoa,Vinicius; Valduga,Marcos O.; Frehse,Fabricio de A.; Vitule,Jean R.S.
ABSTRACT We analyzed the diet and resource partitioning among five syntopic species of Hypostomus Lacépède, 1803 in the Corumbataí River in southeastern Brazil. The gut contents of 352 individuals were assessed and 21 food items were identified and quantified under an optical microscope. The food items found in the gut contents indicate that these suckermouth loricariids are bottom-dwelling detritivorous/periphytivorous catfishes. PERMANOVA and SIMPER analyses indicated variation in the consumption of some resources, and the contribution of periphytic algae was primarily responsible for such dissimilarity. ECOSIM analyses of dietary overlap showed evidence of resource sharing among all species in the dry and rainy periods. This is most likely the result of...

ABSTRACT Southwestern Amazonia has great bird diversity which includes birds specialized in bamboo forests. In this region, bamboo is considered a key element of the landscape. The objective of this study was to investigate and describe the foraging behavior of the Large-headed Flatbill, Ramphotrigon megacephalum (Swainson, 1835) and the Dusky-tailed Flatbill, Ramphotrigon fuscicauda Chapman, 1925, which occur sympatrically in the region and are considered bamboo specialists. This study was conducted between November 2013 and September 2014, within two fragments in the eastern portion of the state of Acre: Fazenda Experimental Catuaba, in the municipality of Senador Guiomard; and Reserva Florestal Humaitá, in Porto Acre. A total of 109 and 97 foraging...

Great unexpected differences between two populations of the intertidal crab Neohelice granulata inhabiting close but contrasting habitats (Crustacea: Decapoda: Brachyura)
Provedor de dados: 103
Autores: Spivak,Eduardo D.; Bas,Claudia C.; Luppi,Tomás A.
ABSTRACT Two populations of the Southwestern Atlantic burrowing crab, Neohelice granulata (Dana, 1851), are separated by only 190 km. They inhabit bays that drain into a Patagonian gulf in the southernmost limit of the geographical distribution of the species: San Antonio Bay (SAO) and San José Gulf (RSJ). The population from SAO has been extensively studied, whereas that of RSJ has not. The main goal of this study is to compare the ecological and habitat characteristics of the two populations, based on samples collected on successive days during the middle of the reproductive season of the crab. The substrate of SAO is composed of a high proportion of gravel and scarce organic matter, whereas the substrate of RSJ presents twice as much silt and clay, and...

Diet and potential feeding overlap between Trichiurus lepturus (Osteichthyes: Perciformes) and Pontoporia blainvillei (Mammalia: Cetacea) in Northern Rio de Janeiro, Brazil
Provedor de dados: 103
Autores: Bittar,Vanessa T.; Di Beneditto,Ana Paula M.
This study describes the diet and assesses potential overlap in the feeding habits of Trichiurus lepturus Linnaeus, 1758 and Pontoporia blainvilleiGervais &amp;amp; D'Orbigny, 1844 in northern Rio de Janeiro, southeastern Brazil. Fishes were numerically dominant in both diets, followed by cephalopods for P. blainvillei and crustaceans for T. lepturus. Both predators move along similar coastal feeding areas in northern Rio de Janeiro, but our results indicate differences in their resource exploitation, what allows for their coexistence.

In this article we research the influence of different sources of carbohydrates (corn, soybean hulls or wheat bran) upon the digestive behavior of 24 confined castrated steers with an initial average age and weight of 20 months and 330 kg born from the cross between Charolais and Nellore. The diet was composed of 40% sorghum silage and 60% concentrate. The time spent on total ruminating (an average of 454.6 min/day) was not influenced by the source of carbohydrate. The animals from the wheat bran treatment spent less time idle (718 min) in relation to those on the corn and soybean hulls treatments, which did not differ between themselves (an average of 792 min/day). The steers from the wheat bran treatment remained less time feeding (184 min/day) compared...

Autores: Costa,Roberto Germano; Ribeiro,Neila Lidiany; Nobre,Priscila Torres; Carvalho,Francisco Fernando Ramos de; Medeiros,Ariosvaldo Nunes de; Martins,Fabrício Ehm.
ABSTRACT The objective of this study was to analyze the effect of housing density on ingestive behavior of male Santa Inês sheep housed individually and in double. Forty non-castrated males were used with an average initial weight of 21.33±2.62 kg and an average age of 120 days. The males were housed in two types of covered stalls: double stalls (two males/stall) of 3.0 m2 and individual stalls of 1.50 m2. Animals housed in individual stalls spent more time ruminating and less time eating than those in double stalls. These animals also spent more time in idleness. Sheep idled approximately 11.43 hours/day (47% of the time), which can be explained by the shorter time spent in rumination, considering that the diet used in this experiment had adequate...

What mineral and vitamin levels to recommend in swine diets?
Provedor de dados: 96
Autores: Gaudré,Didier; Quiniou,Nathalie.
Minerals, including trace-elements, and vitamins are currently introduced into the pig diet in order to obtain suitable performances for the modern pig genotype bred in confinement. Most of the mineral and vitamin contents of cereals and usual protein compounds are characterized by their poor and variable availability. Supplemental diets are then usually needed. This paper, based on literature data, reviews the pig requirement for minerals and vitamins in order to ensure economic and profitable performance. Recent research has focused on phosphorus due to environmental considerations. The widespread use of microbial phytase has decreased the need for inorganic phosphates. Cereals are particularly deficient in calcium and sodium, consequently limestone and...

ABSTRACT The aim of this study was to evaluate the effect of different levels of cottonseed (0, 100, 200, 300 and 400 g Kg-1) on the physical and chemical parameters of the meat of finishing lambs. Forty-five uncastrated male lambs were distributed in a completely randomised design with five treatments of nine replications. The pH values were not influenced by the levels of cottonseed. The lipid and ash content showed significant differences, but were not adjusted by the linear or quadratic equations. Losses during thawing increased, as did cohesiveness, and water activity and water retention capacity decreased as the levels of cottonseed in the diet rose. Tocopherols, cooking loss, toughness and chewiness were adjusted using quadratic equations. In the...

Management and disease of Brazilian chelonians in urban captivity
Provedor de dados: 195
Autores: Flosi, Francis Magno; Garcia, Jerusa Martins; Pugliese, Claudete; Sanchez, Andrea Aranha; Klai, Aparecido.
Brazilian chelonians belong to the following families: Testudinidae (tortoises), Chelidae, Emydidae, Pelomedusidae, Kinostemidae (turtles and terrapins). Many species belonging to these families are kept in domestic captivity and need appropriate management, including nutrition provided by feed formulated to meet the nutritional requirements of each species. By doing so, one can prevent several diseases induced by inadequate management, such as the frequent shell deformities and vitamin deficiencies, especially those regarding vitamin A. The need to preserve these animals as well as their ecosystem is also stressed.

Autores: Tedeschi,Luís Orlindo; Fox,Danny Gene; Sainz,Roberto Daniel; Barioni,Luís Gustavo; Medeiros,Sérgio Raposo de; Boin,Celso.
Mathematical models can be used to improve performance, reduce cost of production, and reduce nutrient excretion by accounting for more of the variation in predicting requirements and feed utilization in each unique production situation. Mathematical models can be classified into five or more categories based on their nature and behavior. Determining the appropriate level of aggregation of equations is a major problem in formulating models. The most critical step is to describe the purpose of the model and then to determine the appropriate mix of empirical and mechanistic representations of physiological functions, given development and evaluation dataset availability, inputs typically available and the benefits versus the risks of use associated with...

Hoplosternum Uttorale (Hancock, 1828) is an abundant species in the lagoons of the upper Paraná river floodplain. This species was sampled in Patos and Guaraná lagoons in the flood period (November/92-May/93) and low water period (June-October/93). To analyse food contents in the diet were analysed stomach of 91 adults. Twenty seven food items were recorded, among them, Testaceae, Nematoda, microcrustaceans, quironomids and organic detritus were predominant. These items allows to characterize the species as bentivore. To study feeding activity were analized 565 adults stomach contents. Food intake was more intense during flooding. Considering diel variation, the species started to eat during dusk, increasing during night, stopping to eat during daytime.

Information on larval fish feeding is essential for understanding their trophic relations, including the management in conditions totally or partially controlled by humans. An experiment was designed to evaluate the larval diets of three commercially important species. Four varzea-lakes and the adjacent river were sampled with bongo and hand nets from January 1993 to November 1995. Larval diets were evaluated by length-classes and capture sites, and were tested by two factor ANOVA. The larvae were feeding in all habitats, except in the flooded forests. The three species had different diets, which varied with their length and lake. The rotifers were the main initial food item of the three species, replaced by fish larvae in Brycon cephalus, cladocerans in...

ABSTRACTResource partitioning is important for species coexistence. Species with similar ecomorphology are potential competitors, especially when phylogenetically close, due to niche conservatism. The aim of this study was to investigate the resource partitioning among populations of two species of lebiasinids (Copella nigrofasciata and Pyrrhulina aff. brevis) that co-occur in a first-order Amazonian stream, analyzing the trophic ecology, feeding strategies and ecomorphological attributes related to the use of food and space by these species. Fish were captured in May and September 2010. The stomach contents of 60 individuals were analyzed and quantified volumetrically to characterize the feeding ecology of both species. Eleven morphological attributes...

Provedor de dados: 37
Autores: GARCÍA-ROSALES,Aaron; ARRIAGA-NOGUΕ&amp;#918;,Alicia; RAMÍREZ-BAUTISTA,Aurelio.
ABSTRACT The genera Iguana and Ctenosaura belong to the Iguanidae family, and populations of most species of these genera have decreased due to anthropogenic effects. The natural history of most species of this family is poorly known, including Ctenosaura similis. Therefore, this study documents some ecological aspects of the species, such as its feeding habits, and habitat and microhabitat use in a population of Isla Contoy in Quintana Roo, Mexico. The data showed that even though C. similis is distributed throughout the island, individuals more commonly use human construction (buildings) of Parque Nacional Isla Contoy (PNIC) and mangrove areas. Microhabitats most used by all age classes and sexes were rocks and trees. The diet of the species is...

 In the Teles Pires River watershed, one of the most common techniques currently used by fishermen to catch fish is to provide a food supplement commonly known as “cevas”. The purpose of this study was to compare the chemical composition of fillets from Brycon falcatus that were caught in both the presence and absence of cevas. The fish were sampled monthly and captured in the following conditions: the Tapaiúna River without cevas, the Teles Pires River with one ceva/100 m, the Celeste River with one ceva/500 m, the Verde River with one ceva/1000 m and the Cristalino River (control area). Subsequent to capture, the fish were euthanized and preserved on ice to determine their water, ash, crude protein and fat contents. Fillets of fish from the control area...

 This study aimed to assess the diet of Poecilia reticulata in rural (RS) and urban stream (US) and under seasonal influence. We hypothesized that rainfall have a strong negative impact on the diet of the species in the US, due to its abrupt effect on food resources; in RS this effect is less apparent. Both streams belong to Pirapó River sub-basin, Paraná River basin. Fishes were sampled bimonthly, between July 2007 and June 2008 in three sample sites along the longitudinal gradient of the streams, using electrofishing. According to the Feeding Index, in both streams the population consumed almost exclusively detritus associated with aquatic organisms (&gt;95%), regardless of the hydrological period. The main taxa explored by fish were Simuliidae in RS and...

Provedor de dados: 42
Autores: Abrunhosa,Fernando A.; Arruda,Danielle C.B.; Simith,Darlan J.B.; Palmeira,Carlos A.M.
The present study investigated whether the callianassid Callichirus major shows a lecithotrophic behaviour during larval development. Two experiments were carried out. In the first experiment, larvae were subjected to an initial period of feeding, while in the second they were subjected to an initial period of starvation. In Experiment 1, 80% of C. major larvae succeeded moulting to juvenile stage in treatment with larvae fed every day. In the treatments with larvae fed for 1, 2 and 3 days there was total mortality before they reached the megalopal stage. In Experiment 2, zoea larvae showed more resistance when subjected to an initial period of starvation in which larvae starved for 1, 2 and 3 days and had survival rates of 100, 60 and 80%, respectively....

Autores: Gugołek,A.; Zabockłi,W.; Kowalska,D.; Janiszewski,P.; Konstantynowicz,M.; Strychalski,J.
Three digestibility experiments on Arctic foxes were carried out. Control groups were fed standard diets (C1 and C2) composed of fresh or frozen animal by-products and steamed ground grain. Dry experimental diets (E1 and E2) contained animal meals, extracted meals and fat, were mixed with water prior to administration. In a preliminary experiment, the digestibility of dry diet E1 moistened with water for 15min and 24h was compared to determine the optimum moistening time during the experimental period proper. The preliminary experiment showed that moistening time had no significant effect on digestibility. In the main experiment, two independent digestibility trials were performed to compare the digestibility of diets fed to foxes during growth (C1 vs. E1)...

Autores: Seixas Filho,J.T.; Santana,A.C.; Martins,A.C.P.F.; Mesquita,E.F.M.; Mello,S.C.R.P.; Hipolito,M.
ABSTRACT Ascites is a pathology characterized by the extravasation of fluid from blood vessels and its accumulation in the abdominal cavity, caused by several associated factors. In this paper, we report the occurrence of this syndrome in breeding male and female Bullfrogs fed a commercial fish feed with 40% crude protein. Liver malformation was already observed due to lack of protein deposition in adult animals from the same spawning. The culture of ascitic fluid showed absence of bacterial growth. Kidney histopathology showed, in both sexes, a large number of tubular structures with strongly eosinophilic hyaline material suggesting colloid growth in both the cortical region and spinal cord. The analysis also revealed granulomas in various stages of...

Bird-termite interactions in Brazil: A review with perspectives for future studies
Provedor de dados: 49
Autores: de Vasconcelos,Marcelo Ferreira; Hoffmann,Diego; de Araújo,Mércia Caroline; Vasconcelos,Prinscila Neves.
We present a review on the principal interactions between birds and termites in Brazil. We found 218 bird species feeding on termites or using termitaria for nesting or perching. Termites were mentioned as food source for 179 bird species. Alates were the most consumed caste. Termitaria were mentioned as nest site for 45 bird species. Some bird species also perch on the top of termite mounds to search for their prey or to conduct territorial and/or courtship displays. Considering all interactions between both animal groups, little is known about the identification of termite genera or species. Therefore, we suggest more detailed studies to be conducted on the natural history and ecology of interactions between birds and termites in Brazil.

A search for predators and food selectivity of two native species of Hydra (Cnidaria: Hydrozoa) from Brazil
Provedor de dados: 49
Autores: Massaro,Fernanda Cristina; Negreiros,Natalia Felix; Rocha,Odete.
The Hydra is the most common representative of freshwater cnidarians. In general, it is found in freshwaters on every continent, with the exception of Antarctica. The aim of the present study is to gather biological and ecological data on aspects of two species of Hydra native to Brazil: Hydra viridissima and Hydra salmacidis. Predation and food selectivity experiments were performed to assess the possible predators and the prey preferences, respectively, of the two species. The results indicate that the two species of Hydra were not consumed by any of the predators that were tested, which are typical predators of invertebrates in freshwater: nymphs of Odonata Anisoptera and the phantom midge larvae of Chaoborus sp. (Insecta), adults of Copepoda Cyclopoida...

Catfishes as prey items of Potamotrygonid stingrays in the Solimões and Negro rivers, Brazilian Amazon
Provedor de dados: 49
Autores: Shibuya,Akemi; Zuanon,Jansen.
In spite of the fact that catfish have rarely been reported as food items in the diets of freshwater stingrays, they are commonly observed in the stomach contents of species inhabiting the Solimões and Negro rivers in the Brazilian Amazon. The stomach contents of six rays from the Solimões River and 64 from the Negro River were analyzed, and catfishes (distributed among the families Callichthyidae, Cetopsidae, Doradidae and Loricariidae) were found in the stomach contents of four and 10 of these rays, respectively, comprising a frequency of occurrence of 20%. These data indicate a relevant participation of catfishes in the diets of potamotrygonid rays in the Amazon, and may reflect the regional diversity and abundance of Siluriformes in the region.

Effect of ascorbic acid on food preference and consumption in captive capybaras (Hydrochoerus hydrochaeris)
Provedor de dados: 52
Autores: Alvarez,Martín Roberto; Kravetz,Fernando Osvaldo.
The aim of this work was to study the short and long term influences of ascorbic acid on Hydrochoerus hydrochaeris, if supplemented in their food. No differences regarding food intake were observed in the absence of vitamin C. On a daily basis, animals accustomed to food containing ascorbic acid prefered to continue eating the same food. Food preference in capybaras did not seem to depend on ascorbic acid availability; however, when accustomed to vitamin C, capybaras might recognize and select ascorbic acid in subsequent food. Mechanisms allowing capybaras to "evaluate" the nutritional quality of their food are discussed, as well as the adaptive value of this behavior in free ranging populations.

Food and the circadian activity of the hypothalamic-pituitary-adrenal axis
Provedor de dados: 56
Autores: Leal,A.M.O.; Moreira,A.C.
Temporal organization is an important feature of biological systems and its main function is to facilitate adaptation of the organism to the environment. The daily variation of biological variables arises from an internal time-keeping system. The major action of the environment is to synchronize the internal clock to a period of exactly 24 h. The light-dark cycle, food ingestion, barometric pressure, acoustic stimuli, scents and social cues have been mentioned as synchronizers or" zeitgebers". The circadian rhythmicity of plasma corticosteroids has been well characterized in man and in rats and evidence has been accumulated showing daily rhythmicity at every level of the hypothalamic-pituitary-adrenal (HPA) axis.

ABSTRACT:  Physical form effect of the pre-starter diet supplied during the post-weaning period from 21 to 41 days of age on diet digestibility and animal performance in terms of zootechnical performances of light-weight (5.82kg) and heavy-weight weaning piglets (6.32kg) was evaluated, as well as the residual effects of the treatments until slaughter. Forty-eight female pigs at 21 days of age were evaluated. The experimental design was completely randomized in a 2x2 factorial scheme (meal/pelleted diet vs. light-weight/heavy-weight piglets), with six replicates for the nursery phase and 12 replicates for the growing-finishing phases. Animals received the experimental diet from 21 to 41 days of age. Data were analyzed with ANOVA, setting the significance in...

ABSTRACT: This study aimed to evaluate the effects of the co-feeding period (C) on the survival and growth of larvae of nishikigoi Cyprinus carpio, during the weaning period from live to inert food. A total of 1680 larvae with initial weight of 1.33 ± 0.12mg and initial length of 6.0 ± 0.33mm were used. The inert diet used was a commercial ration with 55% crude protein and the live food was the newly hatched nauplii of Artemia franciscana. The experiment was conducted following a completely randomized design with six treatments and four replications. Treatments constituted of: a) LF = supply of live food throughout the experimental period; b) C4 = 6 days of live food + 4 days of co-feeding (inert diet and live food) + 16 days of inert diet; c) C8 = 6 days...

The objective of this study was to investigate if piglets that suck anterior teats differ from the others in the litter in birth weight, if they have higher growth rate during lactation, and if this affects behaviour and post-weaning weight gain, when piglets change to a solid diet. For this, the teat order of 24 litters was determined during suckling. Piglets were weaned on the 28thday of age, and 24 groups were formed, composed of one piglet that sucked on the first two pairs of teats (AT) and three piglets that sucked on the other teats (OT). Even though weight at birth did not vary according to teat order, weight gain at weaning differed between the groups (AT: 6.64, S.E. 0.20kg, OT: 5.73, S.E. 0.13kg; P&lt;0.001). After weaning, AT piglets spent more...

The experiment carried out at National Center for Research in Tropical Fish Pirassununga, SP, aiming to determine the effect of the ration processing on the apparent digestibility coefficients of the ingredients for the piau (L. elongatus). A total of 600 males of piau were utilized, allotted into six ponds of 300L. The applied treatments were: grinder processed ration, pelleting ration and extruded ration, utilizing rations with 32% crude protein and 3400 Kcal DE.Kg-1. The experiment was in a randomized blocks design with three treatments, three blocks and two replicates. The data were submitted to variance analysis by the SAEG computational package and the means of the treatments compared by SNK test (5% of significance). The results showed that there...
