Carbon and nitrogen stable isotope analysis was carried out on pelagic fishery organisms caught in light traps and falling nets in the central and western South China Sea in the spring of 2018. The stable isotope values of the sampled individuals were used to elucidate the isotopic variations for the pelagic fishery organisms, to classify species into trophic functional groups, and to compare the differences of trophic structure among the classified trophic functional groups. The results showed that among 23 fishery species the mean δ根据2018年春季于南海中西部海域进行的灯光罩网渔业生物调查,本研究采用碳氮稳定同位素技术,分析了南海中西部海域中上层渔业生物的碳氮稳定同位素基本特征,构建了连续营养谱,划分了营养功能群,并比较了不同营养功能群间的营养结构特征。结果表明: 采集的23种渔业生物δ |
