欧洲鳗鲡三类苗养殖技术初探

Preliminary Study on Culture Technology of Low-vigor Anguilla anguilla

本试验应用膨化饲料养殖欧洲鳗鲡(Anguilla anguilla)三类苗。经过110d的养殖,两个试验组的平均体重分别达到16.13g和15.39g,相对增重率分别为151.1%和142.4%。日均增重量分别为88.3mg和82.2mg。平行养殖试验结果显示存活率分别为97.7%和98.5%,饲料转化率分别为59.1%和58.4%。整个养殖过程基本不换水,完全不用任何药物。

In this experiment, the low -vigor Anguilla anguiUa were fed with expanded feed. After 110 days＇ of growth, the average weight and relative weight gained in each group were individually 15.39g, 16. 13g and 151.1%, 142. 4%. The average increments of body weight were 82. 2mg and 88.3mg. The results of the same two experiments show that survival rates were 97. 7% and 98.5%, the feed conversion rate were 59. 1% and 58.4%. In the whole process of feeding, no water was changed and no medicine was used.
