Gross protein requirements for young catfish appear to be less than those for salmonids. Initially feeding fry require that about 50% of the digestible components of the ration be protein, and the requirement decreases with size. African catfish (Clarias gariepinus) fry were fed a purified diet. Those fed three times a day consumed 1.27±0.27% of biomass per day. The fish fed twice a day exhibited better growth and food conversion. Despite the use of purified diets, performance indices for the group fed twice per day were good. The specific growth rate was 1.24±0.08% per day, the weight gain was 38.51±2.96% during 30 days and the food conversion ratio was 0.72±0.13. (Panagiotis et al. 2003).
