多年来,大伙房水库凶猛鱼类数量大,种类多,严重危害花白鲢鱼种,使放养鱼种成活率较低。由于鱼池少,无论放养鱼种的规格还是数量都不能满足实际需要。从水库的具体条件来看,扩大鱼池也无可能。网箱养鱼技术的普及推广,为培育大水面放养所需鱼种提供了新的途径,但是,由于大伙房水库地处北方,结冰期较长,鱼种培育期短, Over the years, large number of ferocious fishes large number of large reservoirs, many species, a serious threat to the species of silver carp, so stocking fish species lower survival rate. Due to the small number of fish ponds, no matter the size or number of stocking species can not meet the actual needs. From the specific conditions of the reservoir point of view, to expand the pond is also impossible. The popularization and popularization of cage fish farming technology has provided a new way to cultivate the fish species required for large-scale stocking. However, due to the fact that the Dahuofang Reservoir is located in the north, the ice period is longer and the breeding period of species is short,
