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.
