本试验在江西省水产引种育种中心的池塘中进行 ,选择标准池塘 2口 ,每口面积 3亩 ,分别用浮性和沉性配合颗粒饲料进行斑点叉尾主养。经过 7个月的养殖 ,采用浮性配合颗粒饲料起捕鲜鱼 172 0kg、饵料系数 1.6 ;而采用沉性配合颗粒饲料起捕鲜鱼 16 40kg、饵料系数 1.9。结果表明 ,采用浮性配合颗粒饲料无论产量还是饵料系数都要优于沉性配合颗粒饲料。
The experiment was carried out in the pond of introduction and breeding center of aquatic products in Jiangxi Province. Two ponds of standard ponds, each with an area of 3 mu, were chosen for the study. After 7 months of breeding, the floating pellets were used to catch 172 0kg of fresh fish and the feed coefficient was 1.6; while the pellets were used to catch 16 40kg of fresh fish with a pelleted feed, and the feed coefficient was 1.9. The results showed that the use of floating with pellet feed production or bait coefficient should be better than the sink with the pellet feed.
