摘要
[目的]为人工规模化泥鳅幼苗培育提供借鉴。[方法]选择蛋黄、豆浆、奶粉和商品开口料作为试验对象,研究不同开口料对泥鳅幼苗的存活率及活性系数的影响。[结果]96 h后,蛋黄培育泥鳅幼苗的存活率较低,仅有4.5%;豆浆、奶粉、商品开口料培育泥鳅幼苗的存活率较高,分别为41.0%、44.5%和50.0%。蛋黄、豆浆、奶粉、商品开口料培育的泥鳅幼苗活性系数分别为10.40、23.45、24.38和44.13。[结论]在开口初期,泥鳅幼苗应以豆浆、奶粉和商品开口料为主要开口料,其中以商品开口料最好。
[Objective] The research aimed to provide references for large-scale artificial cultivation of loach.[Method] The egg yolks,soybean milk,milk powder and commercial mouth-open feed were taken as test objects to study the effects of different kinds of mouth-open feed on the survival rate and activity coefficient of loach seedlings.[Result] After 96 hours,the survival rate of loach seedlings fed with egg yolk was lower,only 4.5％.The survival rate of loach seedlings fed with soybean milk,milk powder and commercial mouth-open feed were higher,being 41.0％,44.5％ and 50.0％ respectively.The activity coefficients of loach seedlings fed with egg folk,soybean milk,milk powder and commercial mouth-open feed were 10.40,23.45,24.38 and 44.13 respectively.[Conclusion] In the early opening stage,soybean milk,milk powder and commercial mouth-open feed should be used as the mouth-open feed of loach seedlings,and the effect of commercial mouth-open feed was the best.
