Background and Objective: To maintain the current production rate with a consistent acceleration, more research on farming procedures, survival rate, feed conversion capability and growth performance of Cirrhinus mrigala in a confined cultural environment is needed. Therefore, this research aimed to determine the optimal feeding rate at which Cirrhinus mrigala, can develop at its best, with the highest survivability and feeding conversion capability in cages. Materials and Methods: A nine-week research was carried out to assess the growth and survivability of Cirrhinus mrigala in two separate cage treatments. The cages were all the same size and shape and the stocking density in each treatment was 280 per decimal. T1 and T2 received formulated feed and were fed 10 and 7% of their body weight, respectively. Results: The initial mean weight of fish was 25.4±1.63 g in each treatment. Net weight gain in T1 and T2 were found 44.4 and 35.4 g while mean weight gain in percentage was found 74.80 and 39.37% in T1 and T2 , respectively. The mean final length attained at the time of harvesting in T1 and T2 were 17.9±0.26 and 17.5±0.44 cm where the initial length was 9.6±0.83 cm for both treatments. The FCR was found to be lower in T2 than in T1, with values of 5.78 and 4.62 in T1 and T2, respectively, in this study. Temperature, pH and DO were all between 30-32.5°C, 7.3-7.85 and 4.7-6.6 mg L–1, respectively. In T1 and T2, survival rates were found to be 90 and 85%, respectively. Conclusion: Cirrhinus mrigala showed better growth and survival rates when fed 10% of their body weight (T1) compared to 7% (T2) in this experiment, indicating that a 10% feeding rate can be beneficial for cage culture.
