摘　　要：本实验在池塘"零排放"圈养模式下利用4个圈养桶开展不同密度的花[鱼骨](Hemibarbus maculatus)养殖试验,圈养桶直径4.0 m,有效养殖水体20 m^3,分别放养平均规格为12.5 g/尾的花[鱼骨]苗种10 000、14 000、18 000、22 000尾,同时在圈养桶外池塘搭配放养规格为0.5 kg/尾的鳙鱼、白鲢鱼种共1500 kg。经过6个多月的养殖,结果表明:4个圈养桶商品花[鱼骨]产量分别为812 kg、970 kg、1036 kg、986 kg;利润分别为12 279.00元、13 985.00元、14 753.00元、10 517.00元,利润率分别为90%、82%、76%、50%。In this study,the cultivation experiments of H.maculatus with different densities were carried out in the four tanks under the“zero emission”captive culture mode of pond.The diameter of the tank was 4.0 m,the effective aquaculture water body was 20 m3.10000,14000,18000 and 22000 seedlings with an average specification of 12.5 g per fish were respectively raised in the four tanks.At the same time,the pond was equipped with the bighead and silver carp with a specification of 0.5kg per fish outside the tank,a total weight of 1500kg.After more than six months of cultivation,the results showed that the output of commercial H.maculatus in the four tanks were 812 kg,970 kg,1036 kg and 986 kg respectively;the profits were 12279.00 yuan,13985.00 yuan,14753.00 yuan and 10517.00 yuan,respectively,and the profit rates were 90%,82%,76%and 50%,respectively.
