Abstract

The effects of substituting tomato waste meal (crude protein 16%, crude fat 9.1%) with mango seed kernel meal (crude protein 7.2%, crude fat 12.8%) in the diets of Oreochromis niloticus fry at 0.34 g were investigated through a feeding trial. Five isonitrogenous (35% CP) and isolipidic (16% CL) diets were formulated where tomato waste meal was substituted with mango seed kernel meal at 0, 2.5, 5, 7.5 and 10%. The experiment was conducted for sixty (60) days. The stocking density was 10 fish per tank in an isolated system consisting of 10 plastic tanks (50cm x 25cm x 40cm) of 50 liters each. A decreasing trend of the final mean weight (FMW), absolute mean weight gain (aMWG), relative mean weight gain (rMWG) and specific growth rate (SGR) was generally observed as mango seed kernel meal incorporation increased in the diets. The aMWG, rMWG and SGR of fish fed on control diet had no significant differences (P>0.05) with fish fed diets 2.5% and 5%. The dry matter (DM) and lipid contents of the muscle of the fish fed on the control diet were slightly higher than fish fed on diets substituted with mango seed kernel meal. The protein content of the muscle of the fish fed on the control diet was lower than the protein contents of fish fed theother diets except for diet 2.5%. Mango seed kernel meal can substitute 2.5% of tomato waste meal in the diet of Oreochromis niloticus fry without affecting growth performance, feed conversion efficiency and survival.
