通过周年取样、种类鉴定和生物量统计分析,对黄海北部大连地区仿刺参养殖池塘浮游植物种类组成的季节演替和生物量周年变化进行了研究.结果表明:该地区仿刺参养殖池塘中浮游藻类组成依次为硅藻门、蓝藻门、绿藻门和甲藻门,硅藻门和绿藻门作为池塘主要优势种全年均有分布;实验池塘浮游藻类年平均生物量为20.91 mg/L,各池塘浮游植物生物量季节变化趋势相同,最大生物量出现于8月初,为46.18 mg/L,最小生物量出现在2月,为2.26 mg/L.分析表明,浮游植物生物量与水温、透明度成极显著的相关性,并受硝酸氮、磷酸盐、硅酸盐及硝酸氮与磷酸盐的交互作用影响.

@@@@Based on annual sampling, species identification and biomass analysis, the phytoplankton species composition and succession were studied in the sea cucumber aquaculture ponds in Dalian. It was found that the phytoplankton communities in the sea cucumber aquaculture ponds were mainly composed of Bacillariophyta, Cyanophyta, Chlorophyta and dinoflagellates. Bacillariophyta and Chlorophyta species dominated over the year. The biomass of phytoplankton was 20.91mg/L in three test ponds and the seasonal variation of phytoplankton biomass was same. The maximum biomass 46.18 mg / L occurred in early August, the minimum biomass 2.26 mg / L occurred in February. Statistical analysis showed that phytoplankton biomass was highly significantly correlated with the water temperature and transparency and it was affected by nitrate nitrogen, phosphate, silicate and the interaction of nitrate nitrogen and phosphate. The results could be used as the reference for the ecology of aquaculture ponds and manipulation on phytoplankton in the sea cucumber aquaculture ponds.
