Effect of adding worm meal on the growth of carp in aquaculture in Antsirabe Vakinankaratra Madagascar

Abstract

This study, conducted in Antsirabe, examined the effect of incorporating worm meal into carp diets on their growth performance. Fish in group AC1, which received worm meal, showed a mean final average weight (FAW) of 131.64 ± 1.38 g, compared with 131.05 ± 1.40 g for the control group AC0. Weight gain (WG) reached 122.31 ± 1.32 g in AC1, slightly higher than the 121.37 ± 1.29 g observed in AC0. The specific growth rate (SGR) was also marginally improved in AC1 (5.14 ± 0.35%/day) compared with AC0 (5.05 ± 0.34%/day). Both groups recorded a survival rate of 100%, and the condition index (CI) remained stable at 1.17. Overall, the findings indicate that the inclusion of worm meal modestly enhances carp growth without compromising fish health or physical condition. Integrating worm meal into carp feed formulations in Antsirabe appears to be a promising approach for promoting faster and more sustainable aquaculture production.
