报道了1991～1995年对面积为1693hm~2黑龙滩水库渔业利用优化模式研究的结果,主要内容有:水生生物种类组成和现存量调查、浮游植物初级生产力测定、渔获物统计和鱼产力估算;水体理化性状和水位变化对鱼产量和浮游生物群落结构的影响,网箱养殖鲤、草鱼的高产试验结果;多功能水库生态系统的渔业利用优化模式初步探讨。经三年努力,水库鱼产量由622t上升到1255.1t,平均单产750kg/hm~2。为了对水库的渔业功能有更深入的了解和合理的生态管理,总结提出了水库渔业功能与灌溉、防洪发电,大库鱼类增殖与网箱鱼类养殖、一般鱼类养殖与名优鱼类养殖、特别强调渔业发展必须兼顾环境的生态管理原则。
This paper reports the results of the study on the optimization of fishery utilization of Heilongtan Reservoir from 1693 hm2 to 2993 hm2 from 1991 to 1995. The main contents are as follows: species composition and stock of aquatic organisms, primary productivity of phytoplankton, catches statistics and fish productivity The results of high yield test of cage carp and grass carp and the optimization of fishery utilization of multi-purpose reservoir ecosystem are discussed. After three years of hard work, the output of reservoir fish increased from 622 tons to 1255.1 tons with an average yield of 750kg / hm 2. In order to have a deeper understanding of the fishery function and reasonable ecological management of the reservoir, this paper summarizes the functions of the reservoir fisheries and irrigation, flood control and power generation, the proliferation of fish stocks in large ponds and fish breeding in the cage, the general fish culture and the famous fish culture , With particular emphasis on the development of fisheries must take into account the principles of ecological management of the environment.
