| 摘 要： | 本试验用水蚯蚓(A)、鸡蛋黄(B)、自制料(C)等3种开口饵料对虹鳟进行生长试验,试验时间为15d,测定其体长、体重、成活率等指标,比较不同开口饵料对虹鳟生长、成活率的影响。结果表明,不同开口饵料可影响虹鳟生长,但各饵料组间虹鳟仔鱼的全长生长差异不显著,体增重差异不显著;A组成活率最高达62.0%,B组成活率为51.5%,C组成活率为51.0%。

| Abstract: | In this paper Limnodeilu （A）, egg yolk （B） and homemade diet （C） were used to fed rainbow trout fry for 15 days to study the effects of the three initial feeds on growth, and to survival rate of rainbow trout fry. Results indicated that no significant differences were found in the length growth and weight gain between the three groups. The survival rates of group A, B and C were 62.0%, 51.5% and 51.0% respectively. |
