摘要: 以金波子鱼(Papiliochromis ramirezi)为对象,研究3种药物制剂(复方五倍子煎剂、庆大霉素、呋喃西林)对金波子鱼受精卵孵化率的影响以及3种开口饵料(蛋黄粉、草履虫和人工超微粉料)对金波子稚苗存活率的影响。结果表明,添加复方五倍子组孵化率最高,达到了(81.22±6.52)%,显著高于其余两组(P<0.05),且未发现畸形稚苗。因此,在金波子受精卵孵化时添加复方五倍子可显著提高孵化率。使用人工超微粉料作开口饵料的小组稚苗7 d存活率最高,达到(91.33±3.06)%,显著高于其余两组(P<0.05)。因此,人工超微粉料较适合作为金波子稚苗的开口饵料。

Abstract: In the present study, the effects of three different medicine (compound gallnut, gentamicin and furacilin) on hatching rate of fertilized eggs and three initial diets (egg powder, paramecium and artificial ultrafine powder) on survival rate of larva of Papiliochromis ramirezi were investigated. The results showed that the compound gallnut group had the highest hatching rate with (81.22±6.52)%, which was significantly higher than others(P<0.05). Therefore, the hatching rate of fertilized eggs from Papiliochromis ramirezi could be improved remarkably by using the compound gallnut. In addition, the survival rate of larva in group of artificial ultrafine powder was significantly higher than others with (91.33±3.06)%(P<0.05). It indicated that artificial ultrafine powder is more suitable for Papiliochromis ramirezi as an initial diet.
