RESUMEN

Supplementation of pelleted feeds (30% crude protein) consisting of practical ingredients with 250, 375 and 500 mg Cholymbi/kg diet resulted significantly improved the growth of common carp, Cyprinus carpio. Highest final average weight was recorded with diet containing 500 mg Cholymbi/kg. Feeding Cholymbi to fish showed increased carcass protein and fat. Gut protease and hepatopancreas amylase activity were the highest with 500 mg Cholymbi/kg incorporated diet (T3). The results of the present study suggest that Cholymbi, a non-hormonal growth promoter could be effectively used in the diet of common carp. Further investigations are required to work out the optimal dosage required in the diet of common carp.

RESUMEN

To study the growth response of African catfish (Clarias gariepinus) to the diets containing two protein (30 and 35%) and two lipid levels (12 and 18%) in a closed recirculatory system for 60 days, fish were fed to satiation twice daily. The experiment was carried out in triplicate groups. Fortnightly sampling of fish and water samples was carried out. The best result in terms of growth was obtained with the diet containing 34.62% protein and 12.12% lipid. The protein to lipid ratio was 18.57 in the diet that gave best percentage weight gain. However best survival, food conversion ratio and protein efficiency ratio were recorded in the diet containing 29.86% protein and 18.08% lipid.
