在毛主席革命路线指引下,大中小型水库不断兴建,为水产养殖提供了新的水域。水库鱼类资源的培殖主要依靠人工放养鱼种。链、鳙、草、青等鱼类则是放养的主要对象。当水库中的鲢、鳙群体性腺成熟达到生殖年龄时,在繁殖季节,从捕捞的成鱼中选择亲鱼,就地拴养催产,孵化鱼苗。在生产过程中,既省去了亲鱼运输、培育等环节,节省了人力、物力,又不需催产池等专门设备。生产成本比在池塘繁殖鱼苗降低 Guided by Chairman Mao’s revolutionary line, the construction of large, medium and large reservoirs has continued to provide new waters for aquaculture. The breeding of reservoir fish resources depends mainly on artificial stocking fish species. Chain, 鳙, grass, green and other fish is the main stocking. When the population of silver carp and bighead gudgeon in the reservoir reaches the reproductive age, during the breeding season, the broodstock are selected from the adult fish caught and hatched and fry locally. In the production process, it not only eliminates the need for broodstock transport and nurturing, but also saves manpower and material resources as well as special facilities such as the production tank. The cost of production is lower than the breeding of fry in ponds
