摘要
2010年6—9月期间,对卡拉白鱼、泥鳅和鲢鱼混养池塘的水质及浮游生物组成进行检测.结果表明:(1)池塘水型为CMg1水质,属于高pH碱性水体,各项指标均符合水产养殖的水质标准;(2)浮游植物有5门11种,蓝藻门在数量上占优势,生物量则是硅藻门占优势;(3)浮游动物有4门10种,轮虫在数量上占优势,生物量则是桡足类占优势;(4)卡拉白鱼与泥鳅、鲢鱼鱼种混养的产量分别为46.5、52.7和9.2 kg/(100 m2),效益增值6.84元/m2;(5)水质和浮游植物指示物表明卡拉白鱼混养塘为重富营养化水体.
The water quality and plankton composition of polyculture pond of Chalcolburnus chalcoides aralensis with Misgurnus anguiliccautatus as well as Silver carp were investigated from June to September in 2010. The results were as followes ： （ 1 ） The water type was C1Ms with high pH, and each physical and chemical index was consistent with the aquiculture standard; （2） There were eleven species of phytoplankton belonging to five Phyla, among which Cyanophyta was numerical superior, and Bacillariophyta excelled in biomass ; （3） As for zooplankton, ten species of four Phyla were observed, among which Rotipera was numerical superior, and Copepoda excelled in biomass; （4） The yield of Chalcalburnus chalcoides aralensis, Misgurnus anguilicaudatus and Silver carp were 46.5, 52.7 and 9.2 kg/（ 100 m2） separately, and the value-added benefit was 6.84 yuan/m2; （5） The data both from water chemical parameters and the dynamics of phytoplankton showed that the polyculture pond belonged to severe eutrophicated water body.
