库水总盐量约为0.6mg/L,属一般淡水,平均总碱度、总硬度均有利于水生生物的生长发育。浮游植物平均数量474.23万个/L,生物量4.608mg/L,作为滤食性鱼类优质饵料的硅藻门在数量和生物量上占绝对优势。浮游动物平均生物量0.828mg/L,平均数量2498个/L,属一般营养水平。底栖动物生物量0.663g/m2,种类组成简单,数量较少,生物量较小,所能提供的鱼产力较低。针对该水库的渔业资源现状,提出了合理的利用方式。
The total salinity of the water in the reservoir is about 0.6mg / L, which belongs to the general fresh water. The average total alkalinity and the total hardness are all conducive to the growth and development of aquatic organisms. The average number of phytoplankton was 4,742,300 / L and the biomass was 4.608 mg / L. The diatom phytoplankton, as a high-quality feed for filter-feeding fish, was dominant in quantity and biomass. The average biomass of zooplankton 0.828mg / L, the average number of 2498 / L, is a general nutritional level. The amount of zoobenthos biomass is 0.663g / m2, the species composition is simple, the quantity is small, the biomass is small, and the fish productivity that can be provided is lower. According to the status quo of the fishery resources of the reservoir, put forward a reasonable way of utilization.
