Effects of some selective supplemental feeds on the survival and growth of catfish (Clarias batrachus Lin.) fry
Feeding experiments were conducted for 21 days to study the effect of live food (Tubifex sp.) and three prepared supplemental feeds on the growth and survival of 13 day old magur (C. batrachus) fry. It was observed that the growth of fry varied significantly (p<0.05) with different diets. The best growth was shown by the fry fed with Tubifex sp. followed by those fed with the diet containing yeast (30%), milk powder (30%) and chicken eggs (30%). The poorest growth rate was given by the fry fed on yeast (45%) and fish meal (45%). There was no significant difference in survival rates and condition factors among the fry fed with live food and prepared feeds.
