我国湖泊分布很广,面积很大,其中栖息繁衍的鱼类种类很多,有些大湖(如洞庭湖、太湖、鄱阳湖)均在100种以上。可以进行鱼类等经济水生生物增养殖的湖泊数量很多,总面积约2,800余万苗。湖泊是我国淡水渔业生产的重要水域,湖泊渔业生产历史上多是以捕捞自然鱼类为主,由于对水域生态效益的忽视,对水产生产的重视不够,并一度受“以粮为纲”的影响,围湖造田,水利、水工设施闸坝的阻隔,致水域面积缩小,
The lakes in China are widely distributed and large in size, of which there are many species of fish that breed habitually. Some large lakes (such as Dongting Lake, Taihu Lake and Poyang Lake) are all over 100 species. The number of lakes that can be economically hydrophytically cultured, such as fish, is large, with a total area of about 28 million seedlings. The lake is an important water area for the production of freshwater fishery in our country. Most of the history of the fishery production in the lake is mainly the fishing of natural fish. Due to the neglect of the ecological benefit of the water area, lakes pay little attention to aquatic products production and were once subject to “taking grain as the key link” Influence, lake enclosing fields, water conservancy, hydraulic facilities dam barrier, resulting in reduced water area,
