Fishing is the most widespread human exploitation of marine resources, which has an annual cyclical influence on aquatic species in Chinese offshore waters. This study used carbon and nitrogen isotopic ratios as tracers to reveal the changes in trophic level and dietary composition of offshore organisms during four cruises in March, June, August and November 2014. The results indicated that the trophic...
Trophic relationships among common coastal species in the Bohai Strait, North China Sea, were investigated in this study using stable isotope ratios of carbon (13C/12C) and nitrogen (15N/14N) as tracers. During the research cruises of this study, 16 species of invertebrates and 18 species of fishes were collected, as were various food sources (phytoplankton, macroalgae, and sediment). The carbon and...
