Larval rearing and weaning of seabass, Lates calcarifer (Block), on experimental compounded diets
Provedor de dados: 5
Autores: Fuchs, Jacques; Nedelec, Georges.
Larval rearing trials of seabass larvae, either imported from Singapore or obtained from the captive broodstock of IFREMER/C.O.P. at Tahiti, were carried out since 1987, by testing different technologies originally used in South East Asia (green-water culture, sequential water changes) or developed by IFREMER for other species (clear water system, preys enrichment, continuous water renewal).

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.

Vitamin requirements of juvenile penaeid shrimp
Provedor de dados: 5
Autores: Conklin, D.
The results of supplementing crustacean feeds with vitamins are examined specifically from the standpoint of shrimp culture. Micro-nutrients selected for discussion include: water-soluble vitamins of the B-complex, choline and inositol, vitamin C and the fat-soluble group of vitamins: A, D, E and K. Ways in which utilization of vitamins and ultimately dietary demand are altered by physiological state, conditions of culture, as well as factors which impact on feed levels, are explored.

A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

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.

Production of live prey for marine fish larvae
Provedor de dados: 5
Autores: Kraul, S.
Tropical marine fish larvae vary in their requirements for live planktonic food. Selection of live prey species for culture depends on larval size and larval tolerance of water quality. This report describes some of the cultured prey species, and their uses and limits as effective food for fish larvae. Methods are presented for the culture of phytoplankton, rotifers, copepods, and other live feeds.

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.

Enrichment of live foods.
Provedor de dados: 5
Autores: Watanabe, T.
Live foods such rotifers and Artemia are still indispensable for mass propagation of larval fish. At present, more than 20 fish and crustacean species are mass produced in Japanese governmental fish farming centres and private hatcheries. Fry are either released into the coastal areas or used for commercial cultivation. This culture technology is rapidly developing with new species being introduced each year and larval rearing is increasingly identified as the number one constraint. Artemia is used most extensively, particularly for the mass production of Kuruma prawn, Penaeus japonicus .

Mineral requirement of Penaeids
Provedor de dados: 5
Autores: Piedad-pascual, F.
Marine shrimps absorb minerals from their aquatic environment aside from the minerals that come from the food they eat. Thus, the dietary requirement of shrimps for certain minerals will depend on the amounts and availability of these minerals in the aquatic environment. Dietary sources for growth may be necessary due to losses during moltings.

Protein requirements of Penaeid shrimp.
Provedor de dados: 5
Autores: Kanazawa, A.
Proteins are indispensable nutrients for growth and maintenance of live of all animals. The optimum protein levels in diets for shrimps are different among the various species. Squid meal is an effective protein source for many penaeids. The effects of dietary protein, lipid, and carbohydrate levels on the growth and survival of larvae of Penaeus japonicus were examined by feeding trials using purified diet with carrageenan as a binder. As a result, the effects of protein levels on growth and survival of P. japonicus larvae varied with dietary carbohydrate levels but not dietary lipid levels.

Nutrition of the seabass Lates calcarifer
Provedor de dados: 5
Autores: Cuzon, Gerard; Chou, R; Fuchs, Jacques.
The Primary Production Department of Singapore (PPD) studies covered the weaning of seabass from fingerlings stage onwards and the dietary protein requirement of early grow-out fish. Dietary protein requirement of early grow-out seabass was demonstrated to be between 40-50%, at dietary lipid level of 12%, using fishmeal protein. Nevertheless fish growth was significantly higher with trashfish feed, but apparent protein retention was significantly better with formulated feed.

Effects of microalgal diet on growth, survival, biochemical and fatty acid composition of Ruditapes decussatus larvae
Provedor de dados: 5
Autores: Andres Aranda-burgos, Jose; Da Costa Gonzalez, Fiz; Novoa, Susana; Ojea, Justa; Martinez-patino, Dorotea.
Successful bivalve larval growth and survival depend on stored reserves provided by diet. The aim of this study was to evaluate the effects of microalgal diet on growth, survival, together with biochemical and fatty acid composition during larval development in grooved carpet shell (Ruditapes decussatus). Four mono- and multi-species diets were tested: (1) Isochrysis galbana, Pavlova lutheri and Chaetoceros muelleri (1:1:1, IPC); (2) I. galbana, P. lutheri and C. muelleri (1:1:2, IP2C); (3) I. galbana and P. lutheri (1:1, IP); (4) C. muelleri (C). Our results showed that feeding regime greatly influenced larval growth and survival, as well as biochemical and fatty acid composition. Higher growth and survival rates were observed in the IPC, IP2C and C...

Autores: Leaute, Jean-pierre.
Stomach contents of juveniles of sea bass (Dicentrarchus labrax ) and common dab (Limanda limanda ) collected during September 1982 from Bay of Somme and the neighbor coast to Penly, were examined. The most part of the diet of young sea bass are the crustaceans, Sedentary polychaetes appear to be the major food item for common dab. For these two young predator species, food preferences tend to change early: cumaceans, then common edible shrimp, for sea bass, Tube worm tentacles, then part of whole individuals are preferred by common dab.

Adaptations biochimiques intestinales chez la truite: Influence de l'aliment et de la salinite sur quelques proprietes membranaires
Provedor de dados: 5
Autores: Leray, C.
The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

The role of astaxanthin in shrimp pigmentation
Provedor de dados: 5
Autores: Latscha, T.
Carotenoids are exogenously derived isoprenoid compounds which are responsible for pigmentation in crustaceans. While implants and bacteria are able to synthesize these carotenoids de novo, shrimps like other animals entirely depend on their dietary supply. The major carotenoid found in most crustacean tissues and responsible, e.g. for the typical colour of penaeids is astaxanthin. With increasing industrialization in shrimp farming there is a growing demand for synthetic, nature-identical carotenoids, not only for pigmentation, but also for the maintenance of growth and fertility.

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.

Reference diet for crustaceans: Principle of experimentation.
Provedor de dados: 5
Autores: Castell, J.
Feeding trials were conducted with over 22 different crustacean species to compare the potential use of two diets as Standard Reference Diets (SRD) in crustacean research. The two diets (BML 81 S, a casein/albumin based formula developed at the University of California, Bodega Marine Laboratory, and HFX CRD 84, a crab protein concentrate based diet formulated at the Canadian Department of Fisheries and Oceans Halifax Laboratory) were about equal in performance for most species tested. Though neither diet was an ideal SRD, the HFX CRD 84 formulation based upon a purified protein of marine origin was accepted as the interim SRD for use in aquatic crustacean studies.

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.

Status and potential of Australian Lates calcarifer culture.
Provedor de dados: 5
Autores: Mackinnon, M.
Lates calcarifer is distributed widely in northern Australia and is important to both commercial and recreational fisheries. There is the research on hatchery production of the species in 1984 and this work is continuing. Hatchery reared fish have been stocked to reservoirs in northern Queensland and have been used in experimental grow-out trials. Fish weaned onto formulated diets by the age of 25 days were reared to marketable size (&gt; 500 g) in freshwater tanks. Despite suboptimal water temperatures the fish reached market size by the age of twelve months. Taste panel analysis showed that the pellet fed fish were of good quality. The sensitivity of growth rates to water temperature was demonstrated in both grow-out trials and reservoir stockings.

Dawn chorus variation in East-Asian tropical montane forest birds and its ecological and morphological correlates
Provedor de dados: 16
Autores: Chen, W.-M.; Lee , Y.-F.; Tsai, C.-F.; Yao, C.-T.; Chen, Y.-H.; Li, S.-H.; Kuo, Y.-M.
Many birds in breeding seasons engage in vigorous dawn singing that often turns to a prominent chorus. We examined dawn chorus variation of avian assemblages in a tropical montane forest in Taiwan and tested the hypothesis that onset sequence is affected by eye sizes, foraging heights, and diet of birds. Chorus onset and duration varied between sampling months, but generally peaked in the prime breeding season. Overall dawn chorus length increased with, but mean duration per species was negatively correlated with, species richness. The inter-correlation among trait variables in phylogenetic independent contrasts was calculated and examined. Both foraging height and relative eye size were selected as positively explanatory factors, but no dietary effects...

Autores: Pessanha,André Luiz Machado; Araújo,Francisco Gerson; Oliveira,Ronnie Enderson M. C. C.; Silva,Adna Ferreira da; Sales,Natalice Santos.
Eleven ecomorphological attributes and diet of seventeen juvenile fish species were examined to test the hypothesis that morphological patterns determine resource uses in estuarine habitats. Species were separated according to the apparatus to food capture and habitat use (benthic or pelagic) in three different groups: (1) a group with depressed fish body, strong caudal peduncle and enlarged pectoral fins; (2) a second group laterally flattened with a wide protruding mouth, and (3) a third group strongly flattened with small pectorals fins. The following six trophic groups were organized based on prey categories: Zooplanktivores, Benthivores, Omnivores, Detritivores, Macrocarnivores and Insectivores. Significant results (PERMANOVA) between ecomorphological...

As a general rule, sharks and rays play an important role in the energy exchanges among higher trophic levels of the marine food chain and some of them, with an important impact as piscivorous predators.  Squalus acanthias (Squalidae) and  Raja flavirostris (=Dipturus chilensis )(Rajidae), are two elasmobranchs with high apparition frequencies in the SW Atlantic, in the coastal and demersal fishing trawls, co-existing and predating on the principal stocks of bony fish there located, especially the Argentine hake (Merluccius hubbsi). Both species could be transformed into alternative fishing resources, even though they are not currently commercially developed as such. The knowledge on their biology, given in great detail, will provide information for a...

Effect of shrimp head meal inclusion level in litopenaeus schmitti juveniles diet.
Provedor de dados: 20
Autores: Jaime Ceballos, B. J.; Fraga Castro, I.; Galindo López, J.; Alvarez Capote, J.S.
This study determined the effect of different shrimp head meal (SHM) levels (0, 5, 15, 25 and 30%) in practical diets for Caribbean white shrimp juveniles Litopenaeus schmitti (0.29 ± 0.0025 g). A totally randomized experimental design was carried out under laboratory conditions during 54 days. There were no significant differences (p &gt; 0.05) in survival of shrimps in all treatments evaluated. This result indicated that SHM included at 5, 15 and 25% in diet promoted growth. The relation of SHM inclusion level in diet with final weight (FW), food conversion rate (FCR) and protein efficiency ratio (PER) were described by the following quadratic equation: FW = 0.8023 + 0.0604 S - 0.0018 S2, 2 =0.81; FCR = 8.0019 - 0.6081 S + 0.0164 S2, R2 =0.82 and PER =...

Panulirus argus postlarva performance fed with fresh squid
Provedor de dados: 20
Autores: Rodríguez-Viera, L.; Perera, E.
There is a great interest in the growout of spiny lobster postlarva captured in the wild. This activity has been developed  rapidly in Asia and especially in Vietnam. However, lack of appropriated formulated diets remains the main constrain to the  sustainable expansion of this activity worldwide. Until now,  best growth rates have been obtained with the use of high  inclusion of krill meal and/or krill hydrolysates which are expensive. However, squid is today avoided as food ingredient due  to low digestibility reported. Also, fresh squid has been demonstrated to produce poor growth performance in temperate  lobsters, but there is no report for P. argus fed exclusive on fresh squid. This work examines the effect of fresh squid on  growth of P. argus...

Dans le présent travail, les profils lipidiques des acides gras du pétoncle Flexopecten glaber récolté dans la lagune de Bizerte pendant le mois de mai 2007 ont été déterminés. Les pourcentages des différents groupes d’acides gras dans les organes (manteau, muscle adducteur, gonade, branchies et glande digestive) ont été calculés. Les résultats de la chromatographie en phase gazeuse ont révélé des pourcentages élevés en C20:5n-3 et en C14:0 et le rapport C22:6n-3/C20:5n-3 (DHA/EPA) est inférieur à 1, au niveau de la glande digestive du bivalve. Ceux-ci nous ont permis d’en déduire que le régime alimentaire de ce bivalve est essentiellement basé sur les diatomées. Les pourcentages les plus élevés des acides gras polyinsaturés de la série n-3 (EPA et DHA...

The trophic relations of two apex predators, yellowfin and bigeye tuna (Thunnus albacares and T. obesus), and their prey were investigated in the western tropical Indian Ocean. The contents of 173 non-empty stomachs were analysed from specimens caught with longlines and purse seine during scientific and fishing cruises. Diet data were processed by occurrence, by number, and by wet weight and a comparison of diets between surface and deep swimmers made. Crustaceans were the almost exclusive food source of surface-swimming bigeye tuna, with the stomatopod (Natosquilla investigatoris) being the sole prey item recorded in this category. The diet of deep-swimming yellowfin tuna was balanced between epipelagic fish, crustaceans and cephalopods. Bigeye tuna fed...

Régime alimentaire "d'eledone cirrhosa" (Cephalopoda, Octopoda) des côtes et est Tunisiennes
Provedor de dados: 20
Autores: Ezzeddine, S.; Rjeibi, M; Chemmam, B.
L’étude du régime alimentaire du poulpe Eledone cirrhosa est entreprise pour la première fois sur les côtes tunisiennes. Elle est basée sur des échantillons collectés durant la période comprise entre octobre 2005 et septembre 2006 dans les principaux points de débarquements Nord et Est des côtes Tunisiennes et au cours de la campagne de prospections expérimentales réalisée en mars 2005. L’évolution mensuelle du coefficient de vacuité et de l’indice de réplétion montre que ces deux indices varient en fonction du cycle sexuel. D’après l’analyse qualitative du contenu stomacal de l’ensemble des échantillons, les crustacés, représentés dans 84% des estomacs examinés, constituent la proie préférentielle, les poissons et les céphalopodes viennent en second ordre...

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...

Effect of Spirulina platensis meal as feed additive on growth, survival and development in Litopenaeus schmitti shimp larvae
Provedor de dados: 20
Autores: Jaime Ceballos, B.; Villareal, H.; Garcia, T.; Pérez Jar, L.; Alfonso, E.
To evaluate the effect of Spirulina platensis inclusion in microdiets for white shrimp Litopenaeus schmitti larvae, a completely randomized experimental design was developed with 4 treatments and three replicates. Diets with 3 inclusion levels (0, 2.5 and 5%) were prepared. A control was fed Artemia nauplii. Larvae were fed for 120 hours from mysis I to postlavae 1 every 4 h, and water quality parameters were measured daily. At the end of the experiment survival was determined, and the development index of the larvae was calculated. The chemical score of the diet was also determined, using the L. schmitti postlarvae amino-acid pattern as reference. Triptophan and hystidine were the first and second limiting amino acids in the diets. Survival was around 80%...

Provedor de dados: 20
Autores: Blé, M.C.; Alla, Y.L.; Kervarec, F.
Lors de l'introduction d'une espèce en élevage, outre la maîtrise de sa reproduction, il convient de déterminer ses besoins nutritionnels en vue de définir un aliment adapté. La connaissance préalable du régime alimentaire de l'espèce concernée dans son habitat naturel est alors indispensable. La nature même de ce régime est très variable et fonction du milieu, de la saison, de l'espèce et de son stade physiologique. Cette fiche technique a pour but de présenter succinctement trois espèces de poissons habituellement élevés en Côte d'Ivoire et la nature de leur régime alimentaire en milieu naturel. Il s'agit du Tilapia Oreochromis niloticus, du Mâchoiron Chrysichthys nigrodigitatus et du Silure Heterobranchus longifilis.

A research program was carried out to improve and facilitate rotifer (&lt;i&gt;Brachionus plicatilis&lt;/i&gt;) culturing as well as to assure their optimal nutritional quality as a prey, concentrating on the development of a dry and complete rotifer diet that does not require the use of algae and does result in a HUFA rich &lt;i&gt;Brachionus&lt;/i&gt;. The present poster provides results dealing with culture aspects and rotifer nutritional quality. Different diet compositions based on single cell proteins enriched with various nutritional additives were evaluated. Results obtained so far demonstrate that a selected formula of a combined culture and enrichment diet, that does not involve the use of microalgae at all, can be successfully used for growing...

Manipulated yeast diets as a partial algal substitute for the nursery culture of the hard clam &lt;i&gt;Mercenaria mercenaria&lt;/i&gt;
Provedor de dados: 27
Autores: Coutteau, P.; Hadley, N.H.; Manzi, J.; Sorgeloos, P.
Rearing bivalve molluscs in commercial hatchery and nursery systems has so far relied on the production of live algae, which is costly and often unpredictable. Therefore the development of satisfactory artificial diet would greatly reduce the operating costs of bivalve operations. The development of techniques to improve the nutritional composition and digestibility of yeasts resulted in a product with great potential as a substitute for unicellular algae. Previous work on the Manila clam &lt;i&gt;Tapes semidecussata&lt;/i&gt; showed that replacing 80% of the algae by these manipulated yeasts resulted in growth rates of 64 to 93% in comparison with the growth rate obtained for the algal control. In the present study a standard culture test for evaluating...

Effect of dietary essential fatty acids on egg quality and larviculture success of the greasy grouper (&lt;i&gt;Epinephelus tauvina&lt;/i&gt; F.): preliminary results
Provedor de dados: 27
Autores: Dhert, P.; Lim, L.C.; Lavens, P.; Chao, T.M.; Chou, R.; Sorgeloos, P.
In spite of its aquaculture potential, the larval rearing of greasy grouper (&lt;i&gt;Epinephelus tauvina&lt;/i&gt;) remains problematic and is not yet commercially feasible. The low and unpredictable larval survival is due to difficulties encountered in spawning the broodstock, the small size of the larvae at first feeding, and the high sensitivity of the larvae until day 45. The nutritional requirements for the broodstock as well as for the young larvae are still enigmatical. In this presentation the impact of supplementing the highly unsaturated fatty acids (HUFA), eicosapentaenoic (EPA), and docosahexaenoic acid (DHA) to the broodstock and larval diets is illustrated.

Autores: Lim, L.C.; Soh, A.; Dhert, P.; Sorgeloos, P.
This paper describes a pilot culture system for the production of on-grown &lt;i&gt;Artemia&lt;/i&gt; in freshwater ornamental fish farms. The system had 21 culture units, each consisting essentially of three components: an oval-shaped raceway, an air-water lift system and two waste collectors. Using artificial seawater at 20 ppt for culture and at a mean production rate of 3 kg/m&lt;sup&gt;3&lt;/sup&gt; of water in a 12-day cycle, the system had a production capacity of 8 metric tons of on- grown &lt;i&gt;Artemia&lt;/i&gt; a year. Biochemical analyses were preformed to evaluate the nutritional value of the on-grown &lt;i&gt;Artemia&lt;/i&gt; against three conventional live feeds, viz. live &lt;i&gt;Artemia&lt;/i&gt; nauplii, live &lt;i&gt;Moina&lt;/i&gt;...

The importance of highly unsaturated fatty acids (HUFA) such as 20:5omega3 and 22:6omega3 has been investigated for the larvae of the blue shrimp &lt;i&gt;Penaeus stylirostris&lt;/i&gt;. HUFA-rich or HUFA-enriched &lt;i&gt;Artemia&lt;/i&gt; nauplii yielded higher production results in the hatchery than HUFA-poor &lt;i&gt;Artemia&lt;/i&gt; especially when yeast was used as a substitute for algae during the early larval stages. Best results were obtained when a HUFA-rich formulated diet was used as a supplement to the yeast and as an enrichment for the &lt;i&gt;Artemia&lt;/i&gt; nauplii. Differences in production results could be attributed to the HUFA content in living and non-living larval diets.

The effects of increasing levels of dietary phospholipids (PL) on the reproductive performance, egg and larval quality, and lipid composition of females of the freshwater prawn &lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt; were investigated. Three isolipidic diets containing similar amounts of highly unsaturated fatty acids but varying levels of PL (0.8, 2.4 and 4.6%) were fed during 180 days to three groups of eight females originating from Thai ponds. No significant differences were observed for fecundity, egg size and hatchability, starved larvae size, and size, survival and tolerance to stress of 8 day-old larvae. Similarly, no major differences in the lipid composition of the midgut gland, ovaries and muscle tissue of females could be detected. Results...

Comparison of phosphatidylcholine purified from soybean and marine fish roe in the diet of postlarval &lt;i&gt;Penaeus vannamei&lt;/i&gt; Boone
Provedor de dados: 27
Autores: Coutteau, P.; Kontara, E.K.M.; Sorgeloos, P.
The effects of adding two different types of phosphatidylcholine (PC) (purified from soybean lecithin, SPC, or marine fish roe, MPC) on growth, survival and osmotic stress resistance as well as lipid and fatty acid composition of postlarval &lt;i&gt;Penaeus vannamei&lt;/i&gt; was determined. PC was added at a level of 1.5% in a semi-purified diet containing similar levels of essential fatty acids (EFA). A PC-free diet served as the control treatment. The supplementation of 1.5% SPC significantly improved growth and reduced sensitivity to osmotic stress. &lt;i&gt;P. vannamei&lt;/i&gt;-fed MPC showed inferior growth compared to those fed SPC, but yielded better growth and survival than the PC-deprived shrimp. The addition of any of the PC types resulted in a...

New aspects of the use of inert diets for high density culturing of brine shrimp
Provedor de dados: 27
Autores: Dobbeleir, J.; Adam, N.; Bossuyt, E.; Bruggeman, E.; Sorgeloos, P.
Brine shrimp being non-selective filter-feeders, cheap agricultural waste products should be evaluated as potential food sources for their controlled mass culturing. Preliminary results of screening tests performed with wheat bran, soybean meal , rice bran and whey powder in culturing systems of various size are reported. Wheat bran appears to be unsuitable as monodiet for brine shrimp. The other products tested support good growth although specific precautions have to be taken with some foods to avoid problems of water quality during culturing. Processing techniques for the manual or mechanical preparation of inert feeds for &lt;i&gt;Artemia&lt;/i&gt; are indicated. The possibility of influencing the fatty acid pattern of cultured brine shrimp by varying...

Autores: Lavens, P.; Sorgeloos, P.
This paper gives an overview of own experiences with respect to the impact of dietary conditions on the quality of postlarval penaeid shirmp. Direct nutrient-specific effects are documented for highly unsaturated fatty acid (HUFA), phosphatidyl choline (PC) and ascorbic acid (AA). Specific immunostimulants may also contribute to an improved stress resistance of the shrimp fry. Last, but not least, some emphasis is placed on the role of the microflora during the hatchery rearing, the possible reduction of bacteria in the live food adminstered, and the use of probionts through the diet.

Baker's yeast as a potential substitute for live algae in aquaculture diets: &lt;i&gt;Artemia&lt;/i&gt; as a case study
Provedor de dados: 27
Autores: Coutteau, P.; Lavens, P.; Sorgeloos, P.
In this study baker's yeast was evaluated as a substitute for live &lt;i&gt;Dunaliella tertiolecta&lt;/i&gt; algae in the culture of the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; . Consumption of fresh baker's yeast resulted in poor growth and survival of brine shrimp. However, the nutritional value of the yeast significantly improved after complete removal of the yeast cell wall by enzymatic treatment. Baker's yeast was also made digestible for &lt;i&gt;Artemia&lt;/i&gt; by simple chemical treatment which did not reduce rigidity of the yeast cell. The external mannoprotein layer of the yeast cell wall is probably the major barrier to digestion by &lt;i&gt;Artemia&lt;/i&gt; . Chemically treated baker's yeast offers promising possibilities as a substitute for...

The results are presented of preliminary trials conducted with &lt;i&gt;Tapes semiducussata&lt;/i&gt; spat using manipulated yeast products as substitutes for unicellular algae in their diets. Findings showed that spat growth increased with increasing amounts of algae in the artificial diet; growth was very poor when no algae were offered at all. It is concluded that manipulated yeasts may replace a substantial part of the algae in clam diets, but complete replacement is not possible, yet.

L-ascorbyl-2-polyphosphate (ApP) was used as a vitamin C source to study the ascorbic acid (AA) requirements for the early postlarval stages of white shrimp (&lt;i&gt;Penaeus vannamei&lt;/i&gt;). First the stability of ApP in the diets was determined: ApP losses after pelletizing and 10 min immersion in seawater were 25-35% and 30%, respectively. Semipurified diets with five levels of ApP (0, 20, 40, 100 and 200 mg kg&lt;sup&gt;-1&lt;/sup&gt; expressed as active AA were fed &lt;i&gt;ad libitum&lt;/i&gt; to &lt;i&gt;P. vannamei&lt;/i&gt; (PL-14 stage, mean dry weight 0.73 mg) for 26 days.

Autores: Merchie, G.; Lavens, P.; Sorgeloos, P.
HPLC techniques were adapted and standardized for quantification of ascorbic acid (AA) and its derivates in both diets and target organisms. To assess the dietary needs for AA at start of exogenous feeding, the AA content in the various live diets currently used in aquaculture (algae, rotifers, &lt;i&gt;Artemia&lt;/i&gt; ) was analyzed. Application of techniques for boosting vitamin C using ascorbyl palmitate as the source enabled the transfer of elevated levels (up to 2,500 µg AA/g DW) of bioactive vitamin C. Larvae of fish (&lt;i&gt;Clarias gariepinus, Dicentrarchus labrax, Scophthalmus maximus&lt;/i&gt;), white shrimp (&lt;i&gt;Penaeus vannamei&lt;/i&gt;) and prawn (&lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt;) were enriched via the live food chain....

Review on the dietary effects of phospholipids in fish and crustacean larviculture
Provedor de dados: 27
Autores: Coutteau, P.; Geurden, I.; Camara, M.R.; Bergot, P.; Sorgeloos, P.
A beneficial effect of dietary phospholipid (PL) supplementation in purified diets in terms of survival, growth, resistance to stress tests, and occurrence of deformities has been demonstrated in larval and juvenile stages of various species of fish and crustaceans. The exact determination of PL requirements in larvae is complicated due to the difficulty to bio-encapsulate PL in live prey. Furthermore, the great variety in purity and composition of the PL sources, and the experimental conditions (such as diet formulation and extent of co/prefeeding with live food) makes it difficult to compare requirements determined with artificial diets. Larval stages are extremely sensitive to a dietary PL deficiency and require higher levels of dietary PL than...

Fat Chance: Modelling the Socio-Economic Determinants of Dietary Fat Intake in China
Provedor de dados: 31
Autores: Shankar,   Bhavani.
Quantile Regression methods have much to offer the investigation of the determinants of dietary intake. Dietary inadequacy or excess occurs at the tails of nutrient and food intakes, and it seems intuitive that intake responses in these areas will differ from elsewhere along the intake distribution. We apply quantile regression to examine the drivers of a key aspect of dietary health, fat density of energy intake in China. The sample of 2612 individuals between the ages of 20 and 45 is derived from the China Health and Nutrition Survey. The following insights emerge: (i) Fat density increases with income, but worryingly the income effect is more pronounced at the upper conditional tail of fat intake (ii) While it is confirmed that an urban location...

Autores: Xavier,Suzany Aparecida Gomes; Stringhini,José Henrique; Brito,Alexandre Barbosa de; Andrade,Maria Auxiliadora; Café,Marcos Barcellos; Leandro,Nadja Susana Mogyca.
Two experiments were carried out (pre-starter and starter phases) to evaluate the effect of feather and blood meal on performance, organ development and digestibility and retention of nutrients in broilers. In the first experiment, it was used 280 birds and in experiment 2, it was used 240 birds. The experimental diets were formulated with four levels of feather and blood meal (0%, 2%, 4% and 6%) all of them isonutritive and isoenergetic. A metabolic assay was developed on the 4th and 7th days of age in experiment 1 and on the 14th and 17th days of age in experiment 2. In these periods, one bird per experimental unit was sacrificed for determination of morphometry of the digestive organs. In experiment 1, in which it was evaluated the pre-starter phase,...

Provedor de dados: 96
Autores: Mello,Heloisa Helena de Carvalho; Gomes,Paulo Cezar; Rostagno,Horacio Santiago; Albino,Luiz Fernando Teixeira; Rocha,Tatiana Cristina da; Almeida,Rodrigo Lopes de; Calderano,Arele Arlindo.
Four experiments were conducted to study the requirements of available phosphorus (aP) for commercial male broilers of 1-10 day of age (exp.1), 11-21 days of age (exp. 2), 22-33 day of age (exp. 3) and 34-46 days of age (exp. 4), at a constant calcium:aP ratio. A complete randomized design was used in each experiment. The experimental diets were fed ad libitum to 8 replicate groups of ten broilers in each. The increments in the levels of aP ranged from 2.0 to 5.5 g/kg (exp. 1), 1.9 to 5.4 g/kg (exp. 2), 1.8 to 5.3 g/kg (exp. 3) and 1.7 to 5.2 g/kg (exp. 4), in 0.7 g/kg. The parameters evaluated were body weight gain, feed intake, feed conversion ratio and bone parameters. The level of aP in the diet influenced the performance of broilers of 1-10 and 11-21...

Autores: Azevedo,Rafael Vieira de; Fosse Filho,João Carlos; Cardoso,Leonardo Demier; Mattos,Douglas da Cruz; Vidal Júnior,Manuel Vazquez; Andrade,Dalcio Ricardo de.
This study aimed to evaluate economically the inclusion of prebiotics, probiotics and symbiotics in diets of Nile tilapia (4.07 ± 0.30 g), at two stocking densities (0.6 and 1.2 kg m-3). A total of 288 fish were distributed over 32 tanks (40 L) in a completely randomised design, in a 2 x 4 factorial (stocking density x additives), with four replications, over six weeks. The following were evaluated: total feed consumption (FC), final biomass (FB), relative gain in biomass (RGB), apparent feed conversion (AFC), survival rate (SUR), average cost of feed per kg of live weight gain (ACF), total cost of feed (TCF), total cost of production (TCP), gross income (GI), operating profit (OP) and economic efficiency index (EEI). No effect was seen the evaluated...

Superovulatory response, production and embryo quality and the effects of seasonal changes on embryo production of Nellore cows fed on either linseed (n-3) or canola seeds (n-6) were evaluated. Sixteen Nellore cows (550 ± 48.0 kg) were fed on three diets: control diet (CON), diet with linseed (LIN) and diet with canola seed (CAN) during four seasons. There was no difference in superovulatory response and in total corpora lutea produced when diets are taken into consideration. The number of cows that responded to superovulatory treatment was higher in the winter (93.8%) than in the summer (62.5%). No difference with regard to the three diets existed on the average number of total structures (6.20, 4.96 and 6.50), unfertilized structures (2.53, 1.17 and...

The adequate diet of Nile tilapia in their growth early stages is fundamental to the success of culture subsequent stages. The goal of the present work was to evaluate the Nile tilapia growth fed with different diets, and to morphometrically characterized the gastrointestinal tract of this species. The treatments consisted of three diets: (D1) natural food, (D2), commercial feed and (D3) commercial feed + natural food. In the qualitative phytoplankton analysis, there was greater representation of the genus Chlorella, while zooplankton community analysis revealed greater number of Brachionus rotifer. Growth and survival in D2 and D3 did not reveal differences (p &amp;gt; 0.05), while in D1, the results were significantly lower (p &amp;lt; 0.05). The...

Provedor de dados: 62
Autores: Louvandini,Helder; Abdalla,Adibe Luis; Coop,Robert L.; Mc Manus,Concepta Margareth; Gennari,Solange Maria.
Twenty, 2-3-month-old worm free male Holstein calves, were assigned to two groups each containing ten animals. Each group was offered one of two diets: High (HP) and Low (LP) protein with 257 and 91 gkg-1 dry matter respectively, balanced for energy and minerals. After an initial period of 4 weeks on the diets, the calves from each group were subdivided into two groups of four and six calves. A trickle infection of 5,000 Haemonchus placei L3 was given twice a week for nine weeks to the sub group of six calves (I). The remaining four calves from each dietary group were used as non-infected control (C). Four weeks after the last infection, all calves were slaughtered and worm burdens counts. Carried out Biochemical determinations, faecal egg counts and body...

Mixing models and stable isotopes as tools for research on feeding aquatic organisms
Provedor de dados: 65
Autores: Moraes,Cyntia Rafaela Ferreira de; Henry-Silva,Gustavo Gonzaga.
ABSTRACT:  Implementation of mixture models in isotopic analysis has been increasing due to the need to analyze sources and understand their variations in relation to consumers, which requires an accurate determination of their discriminant rate and fractioning. In this context, we presented the main concepts related to the application of stable isotopes and mixing models, with the aim to analyze the benefits and problems of these tools in surveys on nutrition of aquatic organisms. The predominant methods identified included application of the models IsoSource, MixSIR, SIBER and SIAR, with the use of C and N isotopes in research with aquatic organisms. Studies in both freshwater and marine environments were evaluated to determine the relative contribution...
