合肥地区大规格团头鲂商品鱼池塘主养技术与经济可行性研究

Research on Culture Technical in Pond and Economical Feasibility of Large-sized Commercial Fish of Bluntnose Black Bream in Hefei Area

为了研究大规格团头鲂商品鱼池塘养技术与经济可行性,通过团头鲂浦江一号大规格商品鱼主养（80：20模式）试验,分析比较其生长性能及经济可行性,结果表明院2月初放养75 g以上规格的鱼种,当年可以生产规格1 000 g/尾以上的大规格商品鱼;使用粗蛋白含量28%~30%、脂肪含量3%、粗纤维含量6%的饲料养殖效果很好,平均饲料系数为1.82;商品鱼体型好,肉质厚,鳞片黑中透亮,群体间个体生长差异小,主养品种——团头鲂平均单产21 528.0 kg/hm2,产值284 169.4元/hm2,利润54 765.0元/hm2;养殖病害少。

To research the culture technology in pond and economic feasibility of large-sized commercial fish Bluntnose black bream,through main raised （80：20 mode）test of Pujiang River Nol ,we analyzed its growth performance and the economic feasibility.The results showed that the fish of more than 75 g bred in the early of February ,their average weight could reach 1 000 g/tail above which met the standards of large-sized commercial fish. The breeding effect was good with roughage that contained 28%-30% protein ,3% fat and 6% CF ,the FCR was 1.82. The commercial fish＇s size was good, meat thick, scaly black and translucent. Individual growth had little differences. The yield of Bluntnose black bream reached 21 528.0 kg/hm2, the output reached 284 169.4 yuan per hectare, and the profit was 54 765.0 yuan per hectare, and less quaculture disease.
