The Feasibility of Monoculture and Polyculture of Striped Catfish and Nile Tilapia in Different Proportions and Their Effects on Growth Performance, Productivity, and Financial Revenue

Cultivation of species high growth rates is a key achievement sustainable aquaculture development, with the aim increasing animal protein per capita, maintaining food security and preserving freshwater usage. The present study was conducted to evaluate feasibility monoculture polyculture striped catfish, Pangasianodon hypophthalmus, Nile tilapia, Oreochromis niloticus, in different proportions their effect on performance, survival, productivity, feed utilization, body composition, financial revenue. Five experimental treatments were designed as follows: catfish (100%), tilapia (100%) (25%:75%; 50%:50%; 75%:25%, respectively), each three replicates. fish feeding regime consisted isonitrogenous (307.80 g kg?1) isocaloric (19.27 kJ g?1) diets for 14 weeks. results revealed that highest survival obtained monoculture, followed by (in low proportions) (75%:25%). total production m3 reached 5.41 kg m?3 this decreased 52%, 46% 23% 25%; 50%; 75% catfish. gross margin significantly increased, case farmed compared other proportions. While water 6, 0.5, 1 3 $ proportions, respectively. Moreover, cost kilogram gain treatments. performance showed no significant difference among In addition, proximate chemical composition did not differ respect studied Monoculture recommended achieve improve revenue unit (m?3), better development aquaculture.
