Última Ecología trófica de la pescadilla de red, Cynoscion guatucupa (Pisces: Sciaenidae), en aguas del Atlántico sudoccidental. OceanDocs García, S.. Trophic spectrum of Cynoscion guatucupa (striped weakfish) was analyzed through stomach content of individuals coming from two areas of Buenos Aires coast (38° 30'S - 41° 30'S): Argentine - Uruguayan Fishing Common Zone (AUFCZ) and El Rincón area (Argentine Sea, SW Atlantic). The stomach contents of 3323 individual captured in research cruises carried out during 2004 and 2005 was determined. In the diet 39 prey items were identified corresponding to 4 Phyla. Trophic spectrum was determined with Index of Relative Importance (IRI), where fishes were the principal prey (72,53 percentage IRI), crustaceans were secondary prey (27,44 percentage IRI) and with minor values polychaetes and mollusk (0,2 percentageIRI) were found. Pelagic fish was the predominant...

Se evaluó la ecología trófica del Piquero de Nazca (Sula granti) en la Isla Malpelo (Pacífico colombiano), mediante el análisis de contenidos estomacales colectados entre septiembre de 2004 y julio de 2005 durante cinco salidas de campo. A partir de 110 regurgitos inducidos se analizó la dieta, utilizando las variables número, peso y frecuencia de ocurrencia de las diferentes categorías alimentarias y utilizando la distribución de las frecuencias de los tamaños de las presas a nivel general, intraespecífico y temporal. Oxyporrhamphus micropterus (peces mediospicos, familia Hemiramphidae) y peces de la familia Exocoetidae (voladores) fueron los principales componentes hallados en la dieta, seguidos por peces de las familias Carangidae y Escombridae.

Análisis de las capturas, esfuerzo nominal y estructura de los desembarques en 2011 OceanDocs García, S.. Red porgy (Pagrus pagrus) fishery. Analysis of catches, nominal effort and landings structure in 2011. A descriptive analysis of red porgy (Pagrus pagrus) fishery within the Buenos Aires Coastal Ecosystem (BCE) and the Argentine continental shelf, between 34° S and 42° S, during 2011 was performed. The catches landed, of a total of 3,627 t, performed in a direct and incidental way by an heterogeneous fleet of 149 vessels belonging to five strata (Ia, Ib, Ic, IIa and IIb) in 1,527 fishing trips represented a 36.7% decrease as regards 2010. The spatiotemporal analysis allowed to determine that the highest yields of the species were obtained close to 50 m depth, that coincides with the highest surface temperatures in the area, that decrease in a...
