Influence of Live and Dry Diets on Growth and Survival of Goldfish (Carassius Auratus)

The effects of three different diets (dry pellets, pellets plus mosquito larvae and mosquito larvae) on specific growth rate, weight gain, food intake and survival of goldfish were investigated for 30 days. The average final weight of the goldfish feed on the mixed diet (pellets plus mosquito larvae) (16.95 ±1.18 g) was significantly larger than that of fish feed on the dry pellets (14.12 ±1.74 g) and mosquito larvae (12.48 ±3.27 g, p<0.01). The specific growth rate was the highest in the goldfish fed on pellets plus mosquito larvae (56.5%) and the lowest in the goldfish feed on mosquito larvae (41.6%). Food intake was higher in the mixed diet feed groups than in the fish feed on dry pellets and mosquito larvae. Survival rate was 100 % in all the three different feeding groups. The goldfish feed on dry pellets plus mosquito larvae shows significant weight gain, length, specific growth rate etc. No mortality oc- curred during the experiments in any group.
