摘要
本文对俄罗斯鲟 (Acipensergaldenstadti)在规模化养殖生产中的幼鱼驯化方法进行比较研究。用活饵开口后 ,用三种不同方法进行配合饲料驯化试验 ,A组用配合饲料直接驯化 ,B组用饲料和活饵交替投喂 ,C组 (对照组 )用活饵投喂。实验结果 :A组成活率达到建 85 3% ,饵料系数为 1 5 9,平均日增重率 3% ;B组成活率达到 93 4 % ,饵料系数为 1 4 7,平均日增重率 3 4 1% ,结果表明 。
We did the comparison test of the taming method of Acipenser galdenstad ti. fry. After fed with live food, the fry were fed with three different diets i n the taming test. The fry of group A were fed with compound feed directly, thos e of group B with the alternative of diet and live feed and those of group C (co ntrol group) with live feed. The results : the survival rate of group A is 85. 3%, feed coefficient was 1.59, the daily growth rate was 3%; the survival ra te of B group was 93.4%, feed coefficient was 1.47, the growth rate was 3.41% ; The results showed that : the effect of the alternative method of group A was better than group B.
