We aimed to evaluate the effect of compost earthworm on the growth factors and survival rate of Guppy larvae in comparison with commercial Biomar food. Guppy larvae were divided into three groups with three different food rations including group 1 (control) with Biomar food, group two with dried compost earthworm diet and the third group was fed with Biomar as an equal mixture of dried compost earthworm. The larvae rearing lasted for five weeks and then, the data were analyzed statistically. The survival rate (SR) and growth factors such as specific growth rate (SGR), body weight index (BWI) and daily growth rate (GR), in the third group compared to the other groups, and the second group were better than the control group. Significant changes were observed between the groups too (P≤ 0. 05). Thus, the use of dried compost earthworm and Biomar food simultaneously improves the survival rate and growth factors. It is recommended for using in diet.
