Marine fish feeding ecology and food web:progress and perspectives

This paper firstly summarized the experimental methods on marine fish feeding ecology and food web,mainly including stomach contents analysis,stable isotope analysis,compound-specific stable isotope analysis and behavior methods,their development and current applications.Secondly,the progress and achievement of fish diet composition,foraging types,food consumption and distribution in body were introduced.The strategies of marine food web research based on traditional stomach contents analysis,focusing on simplified food web,developing in stable isotope analysis techniques and ecosystem modeling were also presented.Finally,the trends of marine fish feeding ecology and food web research were predicted; furthermore,the problems and deficiency of the development and research in this field in China were discussed.
