Effects of stocking density on production and economics of all-male tilapia (Oreochromis niloticus) culture in a rain fed rice-fish ecosystem
Abstract
- Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate of 4000, 5000, and 6000 ha-1 in treatments T1, T2, and T3, respectively. Water quality was suitable for fish culture. Significantly higher growth was observed in T1 as compared to other treatments. SGR ranged from 1.26 to 1.51. Survival varied between 79% and 88% with treatment T1 producing the highest survival. The highest benefit:cost ratio was obtained in T2 followed by T1 and T3. The best fish production (457.21 kg ha-1) and economic return for the culture period was obtained at 5000 fish ha-1.
