Abstract
GARCIA, Camilo B and CONTRERAS, Cristian Camilo. Trophic levels of fish species of commercial importance in the Colombian Caribbean. Rev. biol. trop [online]. 2011, vol.59, n.3, pp.1195-1203. ISSN 0034-7744.
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. Rev. Biol. Trop. 59 (3): 1195-1203.
