| 摘要 | The trophic ecology of the small yellow croaker (Larimichthys polyactis) was studied using stable isotope analyses. Samples were collected from July to September 2009 and 34 individuals from eight sites were examined for stable carbon and nitrogen isotopes. Stable carbon isotope ratios (delta (13)C) ranged from -20.67 to -15.43, while stable nitrogen isotope ratios (delta (15)N) ranged 9.18-12.23. The relationship between delta (13)C and delta (15)N suggested high resource partitioning in the sampling area. Significant differences in stable isotope values among the eight sampling sites may be linked to environmental diversities involving various physical processes (such as ocean current, wind and tide) and different carbon sources. Furthermore, the stable isotope ratios may also explain the ontogenetic variability in diet and feeding, because delta (13)C and delta (15)N varied significantly with increasing body size. The findings are consistent with other studies on diet analyses in small yellow croaker. It was also demonstrated that stable isotope analysis could be used to estimate the trophic characters of small yellow croaker in feeding patterns and migrating habits.; The trophic ecology of the small yellow croaker (Larimichthys polyactis) was studied using stable isotope analyses.
