网箱养殖团头鲂高产技术研究

Study on Techniqeces of High Yeild of Wuchang Fish in Cage

自１９８９年起，在城西水库中用规格５ｍ×５ｍ×２．５ｍ网箱养殖团头鲂，鱼种箱、成鱼箱配套，投喂颗粒饲料，单产３８ｋｇ／ｍ２，高产４４．３ｋｇ／ｍ２，增重倍数４～１０倍，成鱼上市规格３５０ｇ以上，饵料系数２．６７～３．９８，最高投入产出比达１∶１．６４。

The techniquces of breeding Wuchang fish have been implemented with 5×5×2 5 m cage for breeding,fingerling fed with granulated feeds in the reservior of Chuzhou since 1989.The yield of 38 kg/m 2,the highest 44 3 kg/m 2 was achieved,while the bodyweight of the fish increased 4～10 times.The fish ready for market reached more than 350 g/fish.The forage coefficient was 2 67～3 98.The input-output coefficient was 1∶1 3～1 64.
