摘要
测定了 5种摄食水平下淡水白鲳的生长和饲料利用情况 ,结果表明 ,湿重特定生长率随摄食水平的增加呈线性增长 ;饲料转化效率在最低摄食水平 (1 % )时显著最低 ,在中间摄食水平 (3 % )时显著最高 ;蛋白质效率比和终重变异系数受摄食水平显著影响 ,但在 3 %。
A growth trial was carried out at ration levels(1%, 2%, 3%,4% and saturation) to investigate the effect of ration size on the growth rate in wet weight increased linearly. Food conversion efficiency was lowest in lowest rations(1%) and highest in middle(3%) significantly. Final body weight variation coefficients and protein efficiency ratio were effected by ration size significantly ,but each of them wasn’t different significantly between the 3%, 4% and saturation rations.
