摘要
盐碱地封闭式南美白对虾养殖池中,浮游植物生物量7.0233～66.9334mg/L,平均36.0076mg/L;浮游动物生物量3.127～26.3851 mg/L,平均10.2240mg/L。盐碱地混盐水体中常出现轮虫,而海水池塘较少。色球藻、蓝纤维藻、席藻、螺旋藻等蓝藻门的种类表现出较强的广盐性。并就浮游生物在对虾养殖中的重要作用进行了分析。
Biomass of the phytoplankton and the zooplankton in the brackish pond where the southern American white prawn was reared was 7.0233~66.9334 mg/l and 3.127~26.3861 mg/l, the average biomass was 36.0076mg/l and 10.2240 mg/l respectively. The rotifer was a usual species in the brackish pond, but seldom appeared in the seawater. The algal species of the Cyanophyta such as Chroococcus, Dactylococcopsis, Phormidium and Spirulina were all euryhaline algae.
