摘 要:利用3口池塘开展了主养黄颡鱼(Pseudobagrus fulvidraco)搭配中华鳖(Trionyx Sinensis)的高效健康养殖试验,池塘面积均为0.6hm2,分别放养平均规格为1.0g/尾的黄颡鱼夏花15.0、22.5、30.0万尾/hm2,同时搭配放养规格为0.5kg/尾的白鲢(Hypophthalmichthysmolitrix)鱼种6000尾/hm2,规格为0.25~0.50kg/尾的中华鳖2250只/hm2。采用一次放足、分批上市方式,经过319d的养殖试验,结果表明:3口试验塘黄颡鱼产量分别为9000、12800、14700kg,盈利分别为72300、92900、9630元,利润率分别为35.81%、36.11%、33.00%。Three ponds were used for the efficient,healthy cultivation model test of the Yellow catfish( Pseudobagrus fulvidraco)- soft shelled turtle( Trionyx sinensis) polyculture. 150000,225000,300000 / hm2 yellow catfish( weighed 1. 0g each),were put into the ponds respectively. Meanwhile,both 6000 / hm2 sliver carp( Hypophthalmichthysmolitrix)( weighed 0. 5kg each) and 2250 / hm2 soft shelled turtle( weighed 0. 25 ~ 0. 50 kg each) were added into the ponds. The experiment was in the way of enough pulling and partial fishing. After 319 d of cultivation,the test result showed that the output of the fish in the three ponds respectively were 9000,12800,14700 kg yellow catfish. The production of the three ponds were 72300,92900,96300 Yuan,the profit rate were 35. 81%,36. 11%,33. 00%,respectively.
