本研究分析黄海以鳀鱼为基础食物网中主要生物的碳、氮和磷元素组成以及脂肪酸在组成，包括处于第一营养级的浮游植物、第二营养级浮游动物、鳀鱼以及蓝点马鲛、小黄鱼等鱼类。

One hundred and fifteen species were identified, among which coastal eurythermic species were predominant, showing obvious characteristics of subtropical population fauna. The results showed that the average abundance of phytoplankton in Shacheng Harbour was 3113.24 ind·L-1. The abundance was higher in the inner bay than that in the outer bay in horizontal distribution. The surface abundance was a little higher, but there was no significant gradient in different water layers in vertical distribution. Shannon-Wiener diversity index, Margalef richness index, Pielou evenness index and Simpson dominance index were 2.390, 2.650, 0.726 and 0.306, respectively.

结果表明，该次调查共出现浮游植物115种，种类以沿岸广温广盐性种为主，并呈现较为明显的亚热带海湾种群区系特征，浮游植物的平均丰度为3 113.24 ind·L-1；水平分布上，呈内湾高于外湾的格局；垂直分布上，表层丰度略高，不同水层的分布梯度不明显；Shannon-Wiener多样性指数、Margalef丰富度指数、Pielou均匀度指数和Simpson优势度指数分别为2.390、2.650、0.726、0.306。
