俄罗斯鲟（Acipenser galdenstadti）规模化养殖研究——Ⅱ.幼鱼驯化技术

本文对俄罗斯鲟（Acipenser galdenstadti)在规模化养殖生产中的幼鱼驯化方法进行比较研究。用活铒开口后，用三种不同方法进行配合饲料驯化度试验，A组用配合饲料直接驯化，B组用饲料和活铒交替投喂，C组（对照组）用活铒投喂。实验结果：A组成活率达到建85.3%，铒料系数为1.59，平均日增重率3%；B组成活率达到93.4%，铒料系数为1.47，平均日增重率3.41%，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。

THE STUDY ON INTENSIVE FARMING OF ACIPENSER GALDENSTADTI——Ⅱ.TAMING TECHNOLOGY OF FRY

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.
