Nutritive value and utilization of water hyacinth (Eichhornia crassipes) meal as plant protein supplement in the diet of Clarias gariepinus (Burchell, 1822) (Pisces: Clariidae) fingerlings
120 fingerlings of Clarias gariepinus were fed five different experimental 35% isoproteic diets, a control (0% water hyacinth) and four diets containing different levels of water hyacinth (10%, 20%, 30% and 40%) in place of fish meal as protein source at %% of the body weight for 70 days under laboratory condition. The study revealed a decrease in the growth performance indices as the level of water hyacinth increases.
