- Effects of stocking density on growth performance, digestive enzyme activity, biochemical composition, and economic efficiency of a new strain of reared in cage culture system at Sindh Pakistan. Hassan, Habib Ul Ali, Amjad Wattoo, Junaid Sohail, Muhammad Raza, Muhammad Ahsan Hassan, Syed Adeel Kanwal, Roohi Kabir, Muhammad Rafiq, Naseem Manoharadas, Salim Khan, Mohammad Rizwan Arai, Takaomi The latest strain of is an altered ecological adaptation for sustainable aquaculture and is necessary to sustain stocking density and reduce physiological stress of the new strain. The present study aimed to determine the optimum stocking density, biological performance, and economic efficiency of the Nile tilapia. The 14,000 healthy seeds and uniform weight (40 ± 2.4 g) sex-reversed were stocked in four cages, which are cage (1) 20 fish/m, cage (2) 30 fish/m, cage (3) 40 fish/m, and cage (4) 50 fish/m. The fish were fed 30% dietary protein and feeding frequency three times per day and the feeding rate adjusted according to the fish body weight. Results showed a significantly higher growth, weight gain, and specific growth rate in Nile tilapia stocking density on cage (1), 20 fish/m and cage (2), 30 fish/m compared to cage (3), 40 fish/m and cage (4), 50 fish/m (
