摘　　要：在水温30℃条件下,研究了5.5%、6.5%、7.5%、8.5%的投饲率对体质量为0.73g的莫桑比克鳗鲡黑仔苗30d的生长影响。试验结果表明,投饲率对质量相对增加率、特定生长率、饲料系数有极显著性影响(P<0.01),莫桑比克鳗鲡黑仔苗在水温30℃时的适宜投饲率为7.5%。A growth experiment was conducted at weter temperature of 30 ℃ to determine the optimum feeding rate of eel Anguilla mossambica juveniles with body weight of 0.73 g. The juveniles were fed at five feeding rates from 5.5% to 8.5% （1% increments） for 30 days. The results showed that the relative weight gain rate, specific growth rate and food conversion efficiency were significantly （P〈0.01） affected by all feeding rates. It was found that 7.5 % was of the optimum feeding rate for the eel juveniles .
