Summary:This study was conducted to evaluate the effect of diets containing different levels of protein and energy on the growth of Clarias fingerlings. Clarias fingerlings with an average individual body weight of 1.5 g were stocked in fibre glass tanks each filled with 60 litre of water at a rate of 20 fish per tank. They were fed daily with diets containing 35, 40 and 45 protein and 3000, 3500 and 4000 kcal/kg feed at a rate of 5 of the total body weight for a period of 10 weeks. The feed was given in pellet form and daily feeding frequency was four times. The results showed that with the increasing protein level in the feed, the daily growth rate and lipid retentions also were increasing. Besides, the feed with higher protein content gave the better feed conversion. Only lipid retention was influenced by different energy levels in which the more energy level in the feed the more lipid retention was found. The maximum protein retention (9.23) and the maximum energy retention (8.12) were found for the feed which contains 41.06 and 42 protein, respectively.
