Dietary crude protein requirement of Tilapia nilotica fry
MetadataShow full item record
To determine growth and survival of Tilapia nilotica fry fed formulated practical dry diets with varying crude protein levels, fish were subjected to 3 seperate feeding trials. Isocaloric practical diets containing 20, 25, 30 and 35% crude protein were fed to fry at 15% fish biomass daily for 7 weeks in 2 trials and another set containing 20, 25, 30, 35, 40, 45 and 50% was given for 8 weeks. On the basis of growth, survival and feed conversion, T. nilotica fry required 35% crude protein in the practical diets given at 15% fish biomass.
