| Del 9 al 21 de marzo de 2010, se realizó el Crucero T10/03/01 durante el cual se efectuaron 10 lances de pesca entre 01º21.39' N-03º 02.55' S y entre las longitudes 080º 32.20' W-082º 57.08' W, empleando un palangre de superficie doradero. En los lances realizados frente a Esmeraldas y Manabí, se registraron las mayores capturas, con especímenes con mayor talla y peso promedio, con una temperatura superficial promedio de 27 ºC y termoclina ubicada entre los 10 y 50 m de profundidad con la isoterma de 20 ºC, próxima a la profundidad de cala de la línea de pesca. Hacia el sur (lances 7 al 10), ubicados frente al sur de Manabí, Península de Santa Elena y Golfo de Guayaquil. Las capturas estuvieron representadas por especímenes con talla y peso promedio... |

| The diet composition and feeding habits of Zapteryx brevirostris were studied through stomach contents analysis. 158 specimens were collected from 7 research cruises carried out by Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP, Argentina)between 2001 to 2004, in the Buenos Aires Province (Argentina) and Uruguay coasts (34°-41° S), until 50 m depth. Of the total stomach analysis, 81percentage contained food. According to the alimentary index expressed as a percentage (IA percentage ), indicated that polychaetes, decapods and lancelets were more consumed prey, representing 44.37percentage , 19.94 percentage and 17.36 percentage of the diet, respectively. The amphipods (8.74 percentage ), cumaceans (4.11percentage ) and isopods (3.29... |

| The spiny dogfish, Squalus acanthias is an euribatic, euritermic and cosmopolitan specie. In the Argentine Sea it consumes diversity of preys, characteristic of a generalist and oportunist feeder, butits principal food items are ctenophores, fishes and cephalopods.Diet overlap between sexes was found between 34°-37°S and 101-150 m,where males principally feed on fishes, squid and polichaetes,sharing only ctenophores and hake consumption with the females. Near 62 cm TL there is a shift in the diet, due to an increment of argentine hake Merluccius hubbsi and squid Illex argentinus predation and a diminution in ctenophores Pleurobrachia pileus eating. Feeding shows an increment from north to south, its mode on 42°-43°S.Argentine hake is an important prey... |

| Sharks present strong intraspecific changes in feeding habits, which may vary according to size, geographic location and season. This study analyzed the stomach contents of 52 juvenile scalloped hammerhead sharks (25 females and 27 males) caught by artisanal vessels in the Gulf of Nicoya. Regarding the organisms found in the stomachs, 41.07 % were teleost fish, 30.36 % mollusks and 28.57 % crustaceans. Mollusks presented the highest Relative Importance Index (RII) (43.05 %), followed by teleost fish (41.37 %) and crustaceans (15.58 %). Squids (Loliginidae) were the items with the greatest RII (32.57 %). By means of the Pianka index, a relatively low overlap between sexes was identified, suggesting a spatial sexual segregation and, in consequence, an... |

| 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... |

| The yellowtail kingfish, Seriola lalandi, Carangidae (Valenciennes, in Cuvier y Valenciennes, 1833) is a pelagic, schooling fish, with gregarious behaviour. It is a circumglobal species from tropical and temperate waters. Adult S. lalandi migrate to Argentine waters (SW Atlantic) during summer months (January-April). They have been reported from Argentine waters in depths of 20-36 m between 36°S and 38° and, as reported elsewhere in the world, are often associated with rocky reefs. Samples of S. lalandi were caught using trolling lines during daytime around rocky reefs at 35° 52'-35° 58'S and 54° 45'-54° 48'W, on February 15-22, 2002. Sixty-six adult S. lalandi were analyzed, with specimens measured (LT) and weighted (WT). The length-weight relationship... |

| La comunidad circalitoral de Mytilus platensis presenta dos tipos de tramas tróficos; una que depende de la producción primaria fitoplanctónica y otraíde los detritos orgánicos en sedimentos. (Penchaszadeh,1971 a). Entre los organismos suspensívoros de la comunidad se destacan el propio mejillóm adulto y juvenil, otros Pelecipodos como Ostrea puelchana y Chlarnys tehuelcha , Gasterópodos (Crepidula un~uiformis) y otros organismos como Cirripedios y algunos pOliquetos. Si bien hasta el presente se ha tipificado la dieta de la mayoría de los organismos carnívoros de la comunidad (Penchaszadeh,inéd.1973) no se había analizado cuantitativamente la dieta de los suspensívoros filtradores fitoplanct6fagos. Los organismos filtradores son aquellos que se alimentan... |

| Juveniles y adultos del camarón titi Xiphopenaeus kroyerí (Heller) fueron colectados mensualmente en Costa Verde (Ciénaga), Caribe colombiano, entre septiembre 788 y junio /89. Se determinaron los Ítems alimentarios más importantes, siendo estos en orden descendente: detritus, fragmentos de conchas de bivalvos, poliquetos, foraminíferos y crustáceos. Se detectaron diferencias en la alimentación entre la época lluviosa (septiembre a diciembre) y la época seca (enero a junio), presentándose algunos ítems como rotíferos, esponjas y radiolarios sólo en la época seca. Se analizaron las frecuencias de aparición de los diferentes Ítems en camarones adultos y juveniles, encontrándose que ciertos grupos como rotíferos y briozoos son más frecuentes en juveniles. Se... |
