摘要

Background. Introduction of the common carp, Cyprinus carpio Linnaeus, 1758, may cause a cascade of alterations in trophic webs, among other negative effects, indirectly due to its feeding behaviour. A simplified model site, covenient for studying such interrelations is Lago de P??tzcuaro, M??xico, a shallow lake where carp was first introduced in 1974. The aim of our study was to characterize diet composition, diet breadth and trophic position of C. carpio and local fish fauna, and to assess diet overlap between fish fauna from sites with different habitat characteristics during the wet and the dry seasons.
