Summary: | Palabras claves: ecologa trfica, Bagre marinus, hbitos alimenticios, tems alimenticios, dieta Abstract Understanding the biology of fishing resources is a basic tool in order to define their adequate administration, and for that, trophic ecology studies gather important information about the spatio-temporal distribution of fish populations and their preys. Forty-one food items were identified and classified in different groups of which, fish remains, the fish Anchoa sp, peneid crustaceans, the fish Cathorops mapale, fish eggs and vegetal material were the most frequent ones. To the north, the peneid crustacean preys are dominant in the diets, apparently due to high salinities of this zone that favor their abundance, while the south zone, characterized by large extensions of mangroves, is apparently an adequate area for a wider spectrum of marine and estuarine preys, particularly fish. Key words: trophic ecology, Bagre marinus, feeding habits, food ítems, diet (ProQuest: ... denotes formulae omitted.) INTRODUCCIÓN El conocimiento de la biología de los recursos pesqueros y los efectos de su explotación en los ecosistemas son insumos básicos de los procesos que buscan establecer medidas eficientes para su adecuada administración (Agudelo et al. 2011, Csirke 1989). |
