DIGESTIBILITY AND PERFORMANCE OF WATER HYACINTH MEAL IN THE DIETS OF Clarias gariepinus (BURCHELL, 1822).
Water hyacinth meal (WHM) as an alternative protein source was investigated in this study. Whole water hyacinth plant meal (WPM), water hyacinth leaf meal (WLM) and soya bean meal (SBM) were used to compound three isoproteic (40% crude protein) fish diets. Catfish of 11.2 ± 0.3g average weight were...
