Culture Technique of Shing with Other High-Value Fish Species in the Semi-Arid Zone of Bangladesh

This study was conducted in farmer’s ponds within the northern region of Bangladesh to observe the growth and yield of Shing, Heteropneustes fossilis under a polyculture system. The highest total production of fish registered among the treatments in pattern-1 was 6,331 kg ha⁻¹ with a benefit-cost ratio of 1.52. The best combinations were chosen for multi-location testing (MLT) to verify the previous results. After five months of multi-location testing of the selected combinations with Shing as the main species, the significantly (P < 0.05) highest production of Shing (5,828 kg ha⁻¹), total production of fishes (7,352 kg ha⁻¹) and benefit-cost ratio (1.73) were found.
