江西省大型水库之一的江口水库,放牧式不投饵网箱养殖鲢鳙鱼种的生产规模,每年都在12000箱以上,年产大规格鲢鳙鱼种180万kg左右(鲢占95%),鲢鱼种冬片销价历年为每kg1.4—1.8元,因此网箱养殖鲢鳙鱼种虽然产量高,但效益低。为了改变这一现状,在池塘混(套)养鳜鱼技术模式的启发下, Jiangkou Reservoir, one of the large reservoirs in Jiangxi Province, has a production scale of breeding silver carp and bighead carp farms with annual output over 12,000 boxes. The annual output of large size silver carp and bighead carp is about 1.8 million kg (silver carp accounts for 95% ), Silver carp species winter sale price per kilogram of 1.4-1.8 yuan per kilogram, so cage farming silver carp and bighead carp species, high yield, but low efficiency. In order to change this status quo, under the inspiration of the pond mixed (set) nourishment technology model,
