于2007年11月-2008年3月,研究莆田花蛤生态养殖池浮游动物的种类组成和数量分布特征,并探讨了其与环境因子的关系。结果表明,在藻类池及花蛤养殖池中所采集的样品,浮游动物有34种,其中原生动物25种,占74%,桡足类5种,占15%,端足类1种,占2.9%,其它浮游动物3种,占8.8%,原生动物占比例最多。卡拉拟铃虫,丁丁急游虫、浮游幼虫和强额拟哲水蚤是主要优势种。不同月份浮游植物数量变化直接影响着浮游动物的数量,浮游动物的数量受海水温度、溶氧影响不大,不同月份浮游动物的分布存在差异。
From November 2007 to March 2008, zooplankton samples for the research of species composition and quantity change were collected monthly from the Ruditapes philippinarum high efficient eco - culture ponds in the high area of dam inning zone of Putian city of Fujian province. The relationship between zooplankton and environmental factors in the ponds were also discussed. The results showed that 34 species of zooplankton were identified, including 25 species of Protozoa, 5 species of Copepods, I species of Amphipoda and 3 species of other zooplankton. Protozoa, such as T. karajacensis Brandt, S. tintinnode Entz, nauplius, planktonic larvae and Paracalanus crassirostris were the dominant species. The zooplankton quantity, which changed obviously in different months, seemed directly affected by phytoplankton quantity, and has little relation to the temperature of seawater and dissolved oxygen.
