对水库鱼类种群的管理,有赖于对环境因素所能达到的控制程度,人为限制种群规模的那些环境因素,以达到水库渔业发展的目标。以下若干管理措施将对水库的持续增产,提高水库渔业生产效益有所参考。 一、有选择地减少低质鱼的种类 有选择地减少低质鱼的种类,已成为行之有效的水库管理技术。为了减少低质鱼和部分保留一些经济价质较高的种类,清除的办法是强化捕捞护养法。
The management of reservoir fish stocks depends on the degree of control over the environmental factors and the environmental factors that artificially limit the size of the stocks so as to achieve the goal of reservoir fisheries development. The following number of management measures will be on the reservoir continued to increase production, improve reservoir fishery production efficiency reference. First, the selective reduction of species of low-quality fish The selective reduction of low-quality fish species has become an effective reservoir management technology. In order to reduce the shortage of low-quality fish and to retain some of the more economically-high-quality species, the clear-cut approach is to strengthen the law of fishing and nurturing.
