我国作为发展中国家,放养渔业是内陆渔业的主要方式,如何操纵鱼类实现渔业和水环境保护的协调发展,是实现水库、湖泊渔业健康发展的关键问题。总结了放养渔业与富营养化关系的研究成果,分析了上、下行影响之间的关系,认为放养渔业能够抑制水体的富营养化,但其抑制的程度和范围是有限的。为发挥放养渔业在富营养化抑制方面的更大作用,需要结合不同营养状态和水文特征对放养组合、放养规模以及水草的合理存在空间进行更深入的研究。
As a developing country, stocking fishery is the main way of inland fishery in our country. How to manipulate fish to realize the coordinated development of fishery and water environment protection is the key issue to realize the healthy development of reservoir and lake fishery. The research results on the relationship between stocking fisheries and eutrophication are summarized. The relationship between the upper and lower reaches is analyzed. It is concluded that the stocking fishery can restrain the eutrophication of water bodies, but the extent and scope of its inhibition are limited. In order to make full use of the greater role of stocking fisheries in eutrophication inhibition, we need to conduct a more in-depth study on stocking combinations, stocking scales and reasonable space for aquatic plants based on different nutritional status and hydrological characteristics.
