Labeo rohita (Rohu) is commercially high valued culturable fish species in Pakistan. In the present study, different feeding trials were conducted to determine the efficacy of varying dietary protein levels on the growth response of Labeo rohita fingerlings (average body weight and length; 10.94g, 9.70cm) reared under semi-intensive system. Four different diets having crude protein levels 25, 30, 35 and 40% were formulated using locally available feed ingredients (Rice polish, Maize gluten 30%, 60%, Fish meal, Soybean meal and Bypass fat) and tested for a period of three months. Fishes were fed twice a day at the rate of 3% of their wet body weights. Mean body length and weight gain, percentage weight gain, specific growth rate, average daily weight gain and survival rate were calculate at the end of this study to evaluate the growth performance of Rohu fingerlings under different treatments. Percentage weight gain and specific growth rate were found significantly higher for diet having 35% CP followed by 40%, 30% and 25% CP levels. The survival rate was 100% for all the treatments. Water quality parameters such as dissolved oxygen, temperature and pH were found approximately constant during the study period. The results of this study will be beneficial for researchers and fish farmers for rearing this fish under semi-intensive culture system fed with optimum dietary protein level.
