The effect of different feeding rates on growth of Tilapia hybrid fingerlings (Exotic Oreochromis niloticus x Exotic Oreochromis aureus) reared in Hapas (Cages)

Abstract

Tilapia hybrid fingerlings (exotic Oreochromis niloticus male x exotic Oreochromis aureus female) were fed 40% crude protein diets at 1%, 3%, 5%, 8% and 10% body weight in hapas in triplicate.  The variation in the growth rate was monitored for 8 weeks.

      Growth rate of the hybrid fingerlings increased with increasing feeding rate at 1%, 3%, 5%, 8% and 10% of the body weight.  The feed cost also increased with increasing feeding rate.  The recommended feeding rate for Tilapia hybrid fingerlings in hapas (cages) is 3% body weight to ensure cost effectiveness
