Observation of Water Quality Parameters on Induced Breeding of Bagrid Catfish in Bangladesh

Induced breeding of Bagrid catfish, Mystus tengara, is not widely practiced in Bangladesh, and seed readily available. The study was conducted to identify the optimum range water quality parameters best induced results a hatchery Pabna district, Bangladesh. Fish other related work have been done hatchery. (mean ± SD) temperature, dissolved oxygen, pH were ranged from 29.75±1.22oC 33.94±0.18oC; 4.40±0.57 5.35±1.06 mg/l; 7.10±0.14 7.40±0.28 brood pond 26.50±0.71oC 31.00±1.41oC; 3.80±0.14 5.50±0.42; 7.00±0.00 7.30±0.42 overhead tank, respectively. highest fertilization rate (80%) observed at 7th 8th weeks temperatures 33.94±0.18o C 32.00±1.07oC, as well oxygen concentrations 5.20±1.41 mg/l, 4.60±0.14 values 7.20±0.14, 7.20±0.00, In 9th week experiment, 28.00±1.41oC, 5.50±0.42 mg/l 7.00±0.00, respectively, shown hatching rates. A strong positive correlation found among rate, rate. Particularly, raising pond's showed with On hand, tank This will help technicians comprehending requirements for M. tengara species terms quality.
