黄河水质污染与渔业开发研究

Investigation on Yellow River water pollution and further fishery development

分析了黄河水质污染类型和形成的污染带，对黄河鱼类区系组成及鱼类生长、繁殖、发育、索饵的影响进行研究，提出了水体污染的预防措施和治理办法；认为沿黄两岸低洼易涝盐碱荒滩地的开发应以渔为主，综合经营．利用现有湖、库、河流进行鱼类增殖、养殖和引进适合本水域生长的其它经济鱼类，提高单产和养殖效益，使黄河水域鱼类资源和种群数量得以恢复．

The water pollution type in Yellow River and the corresponding contaminated areas are analysed in this paper. The regional fish construction and the growth, reproduction, development and feeding of fishes are directly affected, the fish migration is blocked, and thus the ecological balance in Yellow River valley is damaged by the water pollution with explicit water pollution effect in the drainage area. The precautionary measures and governing rules against the water pollution in Yellow River are put forward in view of the above existing problems. The lowlying, waterlogged, salinizated and uncultivated land in the Yellow River drainage area should be mainly developed with the fishery in the focal point of the comprehensive exploitment. In order to reinstate the fish resources and increase the culturing benefit and especially the per unit area yield in Yellow River, it is necessary to use now available reservoires, lakes and rivers for the fish culture and multiplication and especially important to introduce other economical fishes suitable to grow in the local water areas.
