El Programa para el estudio y uso sustentable de la Biota Austral (Probiota), como un modesto homenaje, rescata a cuarenta y cinco años de su publicación la iconografía ictiológica de la obra Recursos Acuáticos Vivos incluída en la Serie Evaluación de los Recursos Naturales de la Argentina y editada por el Consejo Federal de Inversiones (CFI) en 1963. Para la ejecución de esta obra el CFI contrató a los doctores Tomás L. Marini y Rogelio B. López ; las ilustraciones de peces que se incluyen fueron preparadas por la Profesora Claudina Abella de López. Este es otro paso dirigido a la consolidación de nuestra disciplina, ya que manteniendo siempre el recuerdo vivo del pasado lograremos afianzar el presente, lo que nos permitirá planificar con fundamentos nuestro futuro.

The migratory population of striped bass (Morone saxatilis) (>400 mm total length[TL]) spends winter in the Atlantic Ocean off the Virginia and North Carolina coasts of the United States. Information on trophic dynamics for these large adults during winter is limited. Feeding habits and prey were described from stomach contents of 1154 striped bass ranging from 373 to 1250 mm TL, collected from trawls during winters of 1994-96, 2000, and 2002-03, and from the recreational fishery during 2005-07. Nineteen prey species were present in the diet. Overall, Atlantic menhaden (Brevoortia tyrannus) and bay anchovy (Anchoa mitchilli) dominated the diet by boimass (67.9%) and numerically (68.6%). The percent biomass of Atlantic menhaden during 1994-2003 to 87.0% during 2005-07. Demersal fish species such as Atlantic croaker (Micropogonias undulatus) and spot (Leiostomus xanthurus) represented <15% of the diet biomass, whereas alosines (Alosa spp.) were rarely observed. Invertebrates were least important, contributing <1.0% by biomass and numerically. Striped bass are capable of feeding on a wide range of prey sizes (2% to 43% of their total length). This study outlines the importance of clupeoid fishes to striped bass winter production and also shows that predation may be exerting pressure on one of their dominant prey, the Atlantic menhaden.
