Graded level inclusion of melon shell in the diet of hybrid catfish (Heteroclarias) as energy source

Abstract

Utilization of agricultural waste- melon shell by hybrid catfish heteroclarias species 3.92±0.05g was investigated in this research. Five isonitrogenous diets containing 40% crude protein with inclusion levels of melon shell meal (MSM) at 0%, 25%, 50%, 75% and 100% in replacement of maize meal was fed to heteroclarias species for 56 days. The results indicated significant differences (P<0.05) in the growth parameters and body compositions. Diet containing 50% melon shell meal gave a significantly high mean weight gain, specific growth rate, protein efficiency ratio, apparent net protein utilization and low feed conversion ratio respectively. The experiment supported the inclusion the inclusion of melon shell meal up to 50% without detrimental effects on the growth of the fish.
