不同投饵率对暗纹东方鲀幼鱼生长的影响OA
Effects of feeding rates on growth of juvenile Takifugu obscurus Abe
比较投饵率水平分别为3%、4%、5%、6%时,对暗纹东方鲀幼鱼生长、饲料效率的影响,以确定暗纹东方鲀幼鱼阶段的适宜投饵率。在23℃下,对规格为3.45～3.56g的暗纹东方鲀幼鱼进行30d的生长实验,结果表明：不同投饵率对暗纹东方鲀幼鱼的特定生长率、质量相对增加率、饲料效率、存活率均有显著影响（p〈0.05）;暗纹东方鲀幼鱼的适宜投饵率为4%,在投饵率为4℅时,质量相对增加率为116.04±0.04%,饲料效率达83.70±0.02%,特定生长率…查看全部>>
A growth experiment was conducted to determine the optimum feeding rate and the effects of different feeding rates on the growth performance of juvenil Takifugu obscurus Abe.Four daily feeding rates were designed at 3%,4%,5% and 6% of the total body weight.Under the water temperature of 23℃,we made 30d of growth experiment on the fish that the average weight was 3.45~3.56g.The results showed that the relative weight gain,specific growth rate,food conversion …查看全部>>
