利用排放的渔业污水先进行单胞藻的（栅列藻ＳｃｅｎｅｄｅｓｎｕｓｏｂｌｉｑｕａｓＴｕｒｐ）培养，再接种培养大型蚤，对栅列藻密度的经时变化，大型蚤种群增长及水体中氮、磷、钾在培养过程中的变动作了测定与分析．研究结果：①悬浮栅列藻在渔用污水中密度变动状态，开始时在充气、直接光照条件下以逻辑斯谛（Ｌｏｇｉｓｔｉｃ）曲线增长；在投放大型蚤并停止充气与直接光照后，则呈直线型下降．②大型蚤在接种进入含栅列藻的渔业污水后，在静态条件下其种群密度亦是按逻辑斯谛曲线增长．③以大型蚤间收式一次累加收获量作为种群总增长量（产出量），其累加数量及干湿重生物量数学模型均呈双对数曲线．④在间收式培养期间，大型蚤密度动态模型为一复合型指数函数．⑤渔用污水经栅列藻及大型蚤培养后再排放水体中氮、磷、钾含量分别下降了８５．５％，８１．１４％，７７．８９％．本研究结果既为枝角类集约化培养技术提供了生态学理论参数，也为污水调控及资源化提出一个良好的技术途径．
Using the discharged fishery wastewater, the culture of Monascus algae (Scenedes nus obliquas Turp) was carried out, then the Daphnia magna was inoculated to cultivate the fleas, the changes of the density of Phyllostachys pubescens, the growth of Daphnia magna and the nitrogen, phosphorus and potassium in the water The changes were measured and analyzed. Results: (1) The density of suspended algae in fishery sewerage fluctuated from logistic curve to inflated and direct sunlight at the beginning. After the daphnids were put on and the inflating and direct light were stopped, Straight decline. ② After flea inoculation into the fishery wastewater containing Prorocentrum, the population density of the flea also increased according to the logistic curve under static conditions. ③ According to the accumulative harvest of large-scale fleas, as the total population growth (output), the cumulated amount and the wet-dry biomass mathematical model showed a double logarithmic curve. ④ During the intercurrent culture, the dynamic model of flea density was a composite exponential function. (5) The contents of nitrogen, phosphorus and potassium in fishing wastewater after being drained by Phragmites australis and Daphnia magna were decreased by 85.5%, 81.14% and 77.89% respectively. The results of this study not only provided ecological theoretical parameters for the intensive culture of Cladocera, but also provided a good technical approach for wastewater regulation and resource recycling.
