Impact of stocking density on growth and production performance of walking catfish, clarias batrachus (linnaeus,1758) and pabo catfish, ompok pabo (hamilton,1822)

This study evaluated the production performance of two species of catfish - Pabo Catfish (Ompok pabda) and Walking Catfish (Clarias batrachus) in six months of semi-intensive rearing. A three-time replica of each stocking density of O. pabda and C. batrachus was conducted. Fingerlings of O. pabda and C. Batrachus were stocked 15000 numbers/ha in Treatments (T) 1 (1.5: 1), 2 (1: 1) and 3 (1: 1.5), respectively. In T1, T2 and T3, the fish production was 3876 ± 94, 3992 102 and 4538 ± 112 kg / ha/ 180 days, respectively. Similarly, all treatments employed the same feed twice a day of the initial stocking of fry. The initial weight of both O. pabda and C. batrachus were 5±0.00g and initial lengths were 7.0 cm and 4.0 cm respectively. The average highest final weight recorded was in T3 (32 ± 3.43) g in O. pabda and C. Batrachus respectively. The average highest final length was observed in T3 (22 ± 0.05 cm) and (21.30 ± 0.09 cm) in O. pabda and C. Batrachus respectively. The survival rate of the stocked O. pabda and C. Batrachus was recorded 64 and 88% in T1; 69 and 90% in T2; 72 and 93.00 % in T3.
