摘要
在３５０、４００、４５０、５００尾／ｍ２的放养密度下，研究了小网箱养鲤效果。结果表明，小网箱放养密度对净产量有极显著的影响，最佳放养密度为４７３尾／ｍ２，随密度增加，出箱鲤鱼的平均体重和生长比速下降。与大网箱相比，小网箱在饲料系数、效益指数等方面具有显著优越性。
The effectiveness of carp cultured under various densities(350,400,450,500 fish/m 2) in small cages were studied.The results showed that the rearing densities had significant effect on the net production. The optimum rearing density of carp in small cages was 473 fish/m 2.As the rearing density increased,the mean body weight and sepicific growth rate decreased.The feed coefficient and beneficial index of carp reared in small cages were significantly superior to those reared in large ones.
