解放后,我国修建了数百座大、中型水库。为了充分利用水体,发展水产事业,有关单位在库内放养了各种经济鱼类。例如从1960年开始,四川长寿湖、浙江新安江、安徽响洪甸、辽宁大伙房等水库,都进行了家鱼的人工繁殖,每库每年生产商品鱼在100～500万斤以上(生产潜力还很大)。一些中型水库发展渔业以后,效益更为显著,不少水库的鱼产达100斤/亩一年以上,
After liberation, China built hundreds of large and medium-sized reservoirs. In order to make full use of water bodies and develop aquatic products, relevant agencies stocked various kinds of economic fish in the storehouse. For example, from 1960 onwards, the lakes of Sichuan Changshou Lake, Xin’anjiang of Zhejiang Province, Xianghongdian of Anhui Province and Dahuofang of Liaoning Province all carried out the artificial reproduction of domestic fish, and the annual production of fish in each store was over 100-500 million kg (production potential Still great). After the development of some medium-sized reservoirs, fisheries, the benefits are even more remarkable. In many reservoirs, the fish production reaches 100 kg / mu for more than one year,
