摘 要：
在草、鲢、鳙夏花鱼种混养池中套养赣昌鲫,赣昌鲫投放密度分别为0.5、1.0、0.6、1.4尾/m2,常规养殖,当年赣昌鲫产量分别为0.175、0.225、0.185、0.216 kg/m2,赣昌鲫规格分别为380、280、340、180 g/尾,赣昌鲫的成活率分别为92.1%、80.4%、91.0%、85.7%,日绝对生长量分别为1.98、1.46、1.62、0.86 g。试验结果证明在草、鲢、鳙鱼鱼种培育池中套养赣昌鲫,其放养密度宜控制在0.5～1.0尾/m2,当年即可养成商品鱼规格应市。

摘 要：
Ganchang hybrid crucian carp fingerling was raised for commercial product in 4 polyculture ponds where the fry of grass carp,silver carp and bighead carp were stocked.The juveniles of the Ganchang hybrid crucian carp were kept at the densitie of 0.5,1.0,0.6,and 1.4 ind/m2;and the total harvest of each pond was 0.175,0.225,0.185,0.216 kg/m2,respectively.The average catching size of the Ganchang hybrid crucian carp was 380,280,340,180 g/ind;while the survival rate was 92.1%,80.4%,91.0%,85.7%,the absolute growth rate was 1.98,1.46,1.62,0.86 g/d,respectively.The results showed that the appropriate rearing density of breeding Ganchang hybrid crucian carp fingerling in the polyculture pond was 0.5～1.0 ind/m2,under which the fingerling could grow to the marketable size in the same year of releasing.
