| The diet of two populations of Mimagoniates rheocharis, from two freshwater streams of the rio Tramandaí, northeastern Rio Grande do Sul, Brazil, are described and compared. The specimens were collected monthly from January 1998 to March 1999, with dip nets and seine nets and preserved in 10% formalin. In laboratory, the standard length of each specimen was measured. The stomachs were removed and dissected for identification of the alimentary items. The data were analyzed using the frequency of occurrence, percent composition and index of alimentary importance methods, being the last two compared among different classes of standard length. Three methods of analysis showed the highest values for allochthonous insects, regardless the locality of collection... |

| ABSTRACT Lophiosilurus alexandri is a carnivorous freshwater fish endemic of São Francisco basin and an endangered species. In this study, we analysed the chemical composition (moisture, protein, ash and lipid), fatty acid profile, and nutritional quality (atherogenic index, thrombogenecity index, ratio between hypocholesterolemic and hypercholesterolemic fatty acids and ω6/ω3 = ratio) of L. alexandri in lotic (river), lentic (hydroelectric dams) environments, under natural fed, and in laboratory controlled conditions fed with commercial diets. Cultured and lentic fish had significantly higher lipid levels (1.5 and 1.9- fold, respectively) than lotic fish. Lentic L. alexandri had significantly higher eicosapentaenoic acid (EPA) levels (4×) than cultured or... |

| 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. |

| 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... |

| Esta investigación se realizó en la camaronera CULTIZAZA, Sancti Spiritus, ante la necesidad de continuar profundizando sobre el comportamiento alimentario del camarón blanco del Pacífico Litopenaeus vannamei, como una vía más para mejorar las condiciones financieras y salud de la camaronicultura cubana. Los resultados indicaron que en época de invierno se requiere de mayor vigilancia en el manejo del alimento en los estanques de cultivo respecto al verano, para evitar suministros innecesarios de alimento que incrementarían la contaminación en los estanques, las situaciones de estrés y aparición de enfermedades que conspiran finalmente con la rentabilidad de la granja. |

| 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... |

| In order to establish the management methods in snook Centropomus undecimalis (Bloch, 1792) broodstock (initial average weight 960 g), during 18 month three phases were developed. Fishes were marked, measured, weighed and distributed in 5 m3 fiber glass tanks (stock density 1.3 kg/m3). In the first phase (3 month), different feeding schedules were applied: 1. feeding in alternate days; 2. feeding every day excluding weekends; 3. feeding twice a day. Before maturation phase and during three month, enriched semi humid food was supplied. Finally, during 12 month, artificial feed was supplied. The appetite dynamics in fishes was influenced by the feeding schedule applied. When food was offered in alternate days, higher consumption was observed. Females showed... |

| From July 1996 to June 1997, in Armação do Itapocoroy, Penha, Santa Catarina State, Brazil, monthly census were done in three areas of traditional fishery and Itacolomis islands. A total of 10021 seabirds were registered, belonging to eight species, five genus and four families. The average number of seabirds per dragging varied between 80,2 and 113,6. Sterna spp, appeared at first in 43,3% of the released by-catch, followed by Larus dominicanus Lichtenstein, 1823, Fregata magnificens Matheus, 1914, Phalacrocorax brasilianus (Humboldt, 1805) and Sula leucogaster Boddaert, 1783. The average size of the fish consumed by the seabirds oscillated from 8,3 cm (Sterna spp.) to 18,5 cm (F. magnificens), with an average time from 6,12 to 7,55 minutes per by-catch... |

| This study examined the diet and trophic structure of the fish fauna, over temporal and spatial scales, as affected by the impoundment of the Iguaçu River in the region of Salto Caxias, Paraná State, Brazil. Sampling was conducted before (March 1997 - February 1998) and after the impoundment (March 1999 - February 2000), at four sampling sites. The stomach contents were analyzed by the volumetric method. The species could be organized in 10 trophic guilds: algivores, carcinophages, detritivores, herbivores, aquatic insectivores, terrestrial insectivores, invertivores, omnivores, piscivores, and planktivores; the first and last guilds were represented only in the post-impoundment period. Similarity patterns and feeding changes were summarized by a... |

| Feeding behaviour of adult European anchovy (Engraulis encrasicolus) was studied in the Gulf of Lions (northwestern Mediterranean Sea) in relation to major abiotic and biotic factors. Observations were made during the main spawning period (summer) for two years, data were collected through hydrological pro-tiling, zooplankton hauls and fish trawling performed in areas of high anchovy density. Temperature, salinity and zooplankton biomass were stratified in the study areas, with cladocerans numerous above the thermocline whereas copepods were dominant below. Engraulis encrasicolus was strictly zooplanctivorous during the main spawning season with copepod and crustacean larvae dominating in stomach contents. Anchovy exhibited high trophic activity during the... |
