- Trophic levels of fish species of commercial importance in the Colombian Caribbean Camilo B. García Cristian Camilo Contreras Biología Colombia Nivel trófico talla de peces peces del Caribe Ecological studies on commercial important fish species are of great value to support resource management issues. This study calculated trophic levels of those Colombian Caribbean fish species whose diet has been locally described. Usable diet data of 119 species resulted in 164 trophic level estimates. An ordinary regression model relating trophic level and fish size was formulated. The regression slope was positive and significantly different from zero (p<0.05) suggesting a scaling of trophic level with fish size. Both the list of trophic levels and the regression model should be of help in the formulation of trophic indicators and models of neotropical ecosystems. 2011 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44922150021 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.3 Vol.59
