| Abstract | Stable isotope technique has been widely applied for identification of animal food sources and reconstruction of food chains and food webs in marine ecosystems, but it has been sparingly used in the research on feeding habits of marine mammals. Compared to the traditional stomach content analysis, which is lengthy, requires a large number of samples, and can only reflect the present state of the sampled organism, the stable isotope technique can reveal its extended biological activity, accurately measure biological source of nutrition, and truthfully identify the biological relationship among populations and the energy flow of the entire ecosystem. Various studies have applied the stable isotope method to investigate feeding in marine mammals such as pinnipeds, polar bears, and others. At present, research of finless porpoise has focused on morphology, behavior, age identification, population dynamics, etc. The previous diet studies mainly use the traditional methods to examine stomach content, whereas feeding studies of the finless porpoise in Liaodong Bay using stable isotopes |
