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 ,B组交替投喂的效果比A组直接驯化的效果为佳
In this paper, we compared the methods of domestication of Acipensergaldenstadti in large-scale aquaculture production in China. After the live bait was opened, the domesticated experiment of compound feed was conducted by three different methods. Group A was directly domesticated with compound feed. Group B was fed with live bait alternately and group C (control group) was fed with live bait. The experimental results showed that the survival rate of group A reached 85.3%, the feed coefficient was 159, the average daily gain rate was 3%, the survival rate of group B reached 93.4%, the feed coefficient was 147 and the average daily weight gain rate was 3 4 1%, the results show that the effect of alternating feeding group B than the direct domestication of group A effect is better
