摘要
利用山涧水开展流水养殖黑脊倒剌鲃,在128m2水泥池中放养规格为10-11尾/kg的鱼种1042kg(10560尾),养殖密度82尾/m2。经271d养殖,收获平均体重511g的倒剌鲃商品鱼5039kg,净产量3997kg;饵料系数2.58,养殖成活率93.34%,净单产31.24kg/m2,利润119.05元/m2,投入产出比为1∶1.78,取得较好的经济效益。
10, 560 black keel Spinibarbus Caldwelli fingerlings with the weight of 10-11ind/kg were cultured in 128m^2 cement pond. and the cultivation density was 82ind/m^2. After 271 days cultivation, 5039 kg fish were harvested. The average weight of individual was 511g, net production 3997 kg, food coefficient 2. 58, survival 93.34%. yield of per unit 31.24kg/m^2, profit 119. 05 Yuan/m^2 , ratio of input and output 1： 1.78. The experiment result showed better economic efficiency.
