SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development CenterTo 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.
Effect of varying crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders CB Santiago, M Bañes-Aldaba & MA Laron -
SEAFDEC Aquaculture Department Quarterly Research Report, 1981 - Aquaculture Department, Southeast Asian Fisheries Development CenterFour-month-old S. niloticus breeders were fed with dry pellets containing 20-50% crude protein and the frequency of spawning involving removal of egg from the mouthbrooding females and growth were determined. When the diets contain high quality proteins from fish meal and soybean oil meal and the amounts of daily food allowance are at satiation level, the influence of increasing dietary crude protein on spawning frequency involving egg removal from the brooder and growth may not be significant.
