Grass carp requires high dissolved oxygen on aquaculture water, breeding grass carp, requires a certain culture technology. We use the fresh water quality of the reservoir clean, rich in dissolved oxygen characteristics of cage fish culture grass carp, the incidence is low, fast growth, high survival rate, higher market prices, substantial economic benefits. Cages cultured grass carp, green pollution-free, well received by the market, is a suitable cage culture of high-quality fish. 1 Cage Setting Geographical and Natural Conditions 1.1 Setting the natural conditions of the cage The cage is set at Jinzhuang Reservoir in Wolong District of Nanyang City.
