Abstract

The present study has been conducted to observe the growth performance (with reference to length, weight, girth and depth) of two important Indian Major Carps, rohu (Labeo rohita) and mrigal (Cirrhinus mrigal). The experimental fishes were fed on pellets prepared from the combination of different vegetable waste for 60 days. The pelleted feed was given to the Indian Major Carps as a replacement of costly feeds. It was observed that the survival rate of experimental fishes was 100% during the experiment. The growth rate of fishes fed on the different feed (commercial feed(F-1), control feed(F-2) and the experimental feed(F-3)) was observed fortnightly. And the growth of length, weight, girth and depth was calculated with reference to SGR%. The SGR% for 60 days of experiment was 0.163%, 0.704%, 0.377% and 0.403% respectively in case of experimental fishes which was higher than the fishes fed on control feed as it was 0.085%, 0.219%, 0.173% and 0.107% respectively. It was also higher than the fishes fed on commercial feed as the SGR% of fishes with reference to length, weight, girth and depth was 0.064%, 0.184%, 0.187% and 0.129% respectively. This result shows the good impact of vegetable waste pellets on the growth of fishes.
