调查结果表明:锦州湾生态监控区海域共鉴定出浮游动物36种,包括桡足类、水母类、毛颚类、磷虾、糠虾和各种浮游幼体以及一些原生动物。其中,小拟哲水蚤、强额拟哲水蚤、双毛纺锤水蚤为优势种,合计占浮游动物总个体数的56%。浮游动物的种类数和总个体数水平分布格局都表现为湾外大于湾内,浮游动物数量与叶绿素a的含量变化基本一致,但相关不显著。浮游动物多样性指数平均值为2.232,说明该海域水质和生物群落较稳定、成熟。
The survey results showed that 36 species of zooplankton were identified in Jinzhouwan Ecological Monitoring Area, including copepods, jellyfish, chinchillas, krill, shrimp and various planktonic lakes and some protozoa. Among them, the small foxtail Daphnia magna, a large amount of simulacrum daphnia, Daphnia magna was the dominant species, accounting for 56% of the total number of zooplankton. The number of species of zooplankton and the distribution pattern of the total number of individuals showed that the number of zooplankton was greater than that of chlorophyll a in the bay, but the correlation was not significant. The average value of zooplankton diversity was 2.232, indicating that the water quality and biome in this area are stable and mature.
