A drift study of vertical distribution and mortality of Engraulis anchoita eggs and larvae. OceanDocs
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...

A new short-rostrum odontocete (Mammalia: Cetacea) from the middle Miocene of the Eastern Netherlands Naturalis
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.

Alimentação dos peixes detritívoros da Baía Tuiuiú, rio Paraguai, Pantanal de Mato Grosso do Sul, Brasil. Infoteca-e
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...

Alimentación de la vieira patagónica Zygochlamys patagonica (King y Broderip, 1832) en el banco Reclutas (39ºS-55ºW) durante un período anual OceanDocs
Schejter, L..
Zygochlamys patagonica is distributed in the Atlantic Ocean from 35 degree S to Tierra del Fuego (Argentina), and in the Pacific Ocean, up to 42 degree S, between 40 and 200 m depth. There are 9 beds in the Argentinian Sea. Scallops are suspensivore organisms, feeding on detritus and phytoplankton. The aims of this thesis are to make a quali-quantitative study of the diet of the Patagonian scallop, to detect seasonal changes in diet and to link these results with oceanographic conditions and with the growth pattern. Gut contents of 180 scallops were analyzed from samples (n=30) taken in June, August, October and November 1996, and February and March 1997. This procedure was tested statistically. Twelve species of diatoms and resting stages, five species of...

Alimentación de Merluccius hubbsi e impacto del canibalismo en la región comprendida entre 34°50'-47°s del Atlántico Sudoccidental. OceanDocs
Sánchez, M.F.; Garcia de la Rosa, S.B..
Feeding of Argentine hake during winter 1994, between 50 and 370 m of depth, in the studied area (34°50'-47°S), is based on the consumption of zooplanktonic crustaceans, fishes and cephalopods. Maximum feeding incidence is found at 36°-40°S (51. ), in sea layer of 80-130 m deep (62. ) and between 8:00-10:00 hours (36,6. ). Cluster analysis shows five spatial groups, with similar length distributions and characteristic principal prey items combination. The males of all sizes show a trend to feed on euphausids and hiperiids amphipods. The females eat more quantities of hake, short fin squid and other fishes. There is a change in diet related with predator size, from 47 cm TL onwards for males, and from 53 cm TL for females. This change consists in a decrease...

Alimentation du merlan Merlangius merlangus L. en Mer Celtique ArchiMer
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.

Alimentation expérimentale de l'huître Crassostrea gigas à l'aide de navicules bleus Haslea ostrearia (Simonsen) de différentes tailles ArchiMer
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...

Análise comparativa entre tipos de alimentação de Micrurus corallinus (Serpentes, Elapidae) em cativeiro Iheringia, Sér. Zool.
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.

Aspectos biológico-pesqueros del abadejo (Genypterus blacodes) OceanDocs
Renzi, M.A..
The kingklip is one of the species that has been traditionally exploited in the Argentine Sea. Although captures were not very important, they have been increased in the last years. In this paper, the structure of the concentration areas of summer, spring and winter distribution and other biological aspects were analyzed, on the basis of the data collected during cruises carried out by R/V"Walther Herwig" and R/V"Shinkai Maru" in Argentine waters during 1978/79. The trophic spectrum of the kingklip comprises mainly food species of the Classes Pisces and Crustacea as well as other complementary groups like Mollusca, Brachiopoda and haliacea.

Astyanax paranae Eigenmann, 1914 (Characiformes: Characidae) in the Alagados Reservoir, Paraná, Brazil: diet composition and variation Neotropical Ichthyology
Abelha,Milza Celi Fedatto; Goulart,Erivelto; Kashiwaqui,Elaine Antoniassi Luiz; Silva,Marlene Rodrigues da.
Aspects of the feeding ecology of a small characin, Astyanax paranae, were studied during 1996/1997 and 1998/1999 in the Alagados Reservoir, Paraná, Brazil (25º01'50.0'' S; 050º03'41.9'' W). Fishes were quarterly captured from the reservoir's riverine and lacustrine zones and stomachs contents of 711 adult individuals were analyzed by volumetric method. Species' feeding spectrum and spatial, temporal and sexual variations on diet were evaluated. Data matrix was summarized by detrented correspondence analysis (DCA) and the axes scores from DCA were used as variables in one-way ANOVA of null models to test diet variations. Astyanax paranae fed on detritus/sediment, plant matter, algae and aquatic and terrestrial invertebrates. The time-space prevalence of...

GUIMARAES FILHO, C.; SOARES, J. G. G..
O estudo teve como objetivo avaliar um modelo fisico do sistema de cria de bovinos para as areas mais secas do semi-arido brasileiro, associando a pastagem natural com pastos cultivados tolerantes a seca. A caatinga foi pastejada no periodo verde, e o capim buffel no restante do ano. A suplementacao com leucena ocorreu no periodo seco, sob pastejo direto e feno no cocho. Parametros de desempenho, monitorados de novembro de 1991 a outubro de 1995, mostraram uma taxa media de paricao da ordem de 72,8% ao ano e taxas de mortalidade praticamente nulas. O peso vivo medio dos bezerros aos 205 dias de idade foi de 153,4 kg e a producao de bezerros desmamados foi de 109,5 kg/matriz exposta/ano e de 25,5 kg/hectare/ano. Os resultados sao considerados bastante...

Bases biologiques de la production de deux Mollusques d'intérêt économique: reproduction chez Megathura crenulata, reproduction et développement chez Crassostrea gigas ArchiMer
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...

Biologia alimentar de Steindachnerina brevipinna (Characiformes, Curimatidae) do rio Ibicuí-mirim, Rio Grande do Sul, Brasil Iheringia, Sér. Zool.
Giora,Júlia; Fialho,Clarice B..
The feeding biology of Steindachnerina brevipinna (Eigenmann & 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.
