| 摘 要： | 实验设置1.0%,1.5%,2.0%,2.5%,3.0%五个不同投饵率水平,在水温30℃的条件下,选取同一种饲料,对规格为3.67±0.30g的花鳗鲡黑仔苗进行40d的生长实验。结果表明,投饵率对花鳗鲡黑仔苗的相对增重率、特定生长率、饲料转化率均有显著性影响（p〈0.05）,花鳗鲡黑仔苗生长的适宜投饵率是2.0%;在此投饵率下,花鳗鲡黑仔苗的饲料转化率为（47.39±1.17）%,特定生长速率为（1.08±0.03）%/d,相对增重率为（52.49±1.04）%,存活率为100%。

| Abstract: | A growth experiment was conducted under the conditions of temperature 30℃,to determine the optimum feeding rate and the effects of different feeding rates on the growth performance of the black fry（Anguilla marmorat）,size of 3.67±0.3g.Five feeding rates from 1.0% to 3.0%（at 0.5% increments） body weight per day were used in this test.An identical diet was given to the black fry for 40 d.The main result showed that the relative weight gain（RWG）,specific growth rate（SGR）,food conversion efficiency（FCE）,net weight increase and survival rate（SR） of the black fry were significantly（p〈0.05） affected by all feeding rates,and the optimum feeding rate of the black fry is 2.0%;At this feeding rate,the FCE was（47.39±1.17）%,the SGR was（1.08±0.03） %/d,the RWG was（52.49±1.04）%,SR was 100%. |
