Abstract:

Food resources are crucial for the survival and reproduction of marine animals. The trophic niche of marine organisms refers to the ecological roles and functions in marine ecosystem. It plays an important role in studying interspecific relationship, resource partitioning, community structure and function. In this study, by collecting the relevant research on trophic niche of marine animals, we review current research methods (stomach content analysis, bulk tissue stable isotope analysis, fatty acid profiles and compound-specific isotopic analysis) and their applications by focusing on their corresponding ecological models on quantitively evaluating the breadth and overlap of the trophic niche. Moreover, potential development and directions for further studies are presented, with the aim of providing supports for future research on feeding ecology of marine animals.

Key words: marine animal, trophic niche, stomach content analysis, stable isotope, fatty acid profile, compound-specific isotopic analysis
