A study on the landings of various species recorded randomly from December 2003 to June 2004 from fish landing and marketing centers on the Ken at Banda, on the Paisuni at Karwi and Tons at Chakghat and Sadiapur (Prayagraj), revealed that the average catch day-1 of the Ken river was dominated by Cyprinus carpio followed by Aorichthys spp. and miscellaneous fish. In contrast the Paisuni R. was dominated by Labeo calbasu followed by Hypophthalmichthys molitrix and miscellaneous while the latter group dominated over Aorichthys spp and L. calbasu in the Tons R. Among selected species Labeo rohita commands higher price (Rs 61.7), Tor tor moderate (Rs 52.5) and L. calbasu lower price (Rs 37.5).

Breeding Practices

This study was conducted on the 13 hatcheries of Rajshahi district from March to December 2013 to know about the fry production status, induced breeding practices and cost-profit status. Average fry production of Labeo rohita, 93.38±83.32 kg, Catla catla, 62.00±60.84 kg, Cirrhinus cirrhosus, 77.46±58.61 kg, L. calbasu, 14.20±14.60 kg, L. bata, 53.73±50.56 kg, L. gonia, 10.00±0 kg, Heteropneustes fossilis, 5.00±0 kg, Clarias batrachus, 20.00±0 kg, Hypophthalmichthys molitrix, 149.77±138.45 kg, Aristichthys nobilis, 104.54±148.11 kg, Ctenopharyngodon idella, 19.20±15.35 kg, Cyprinus carpio 108.08±77.39 kg and Barbonymus gonionotus, 23.10±14.04 kg were recorded in the surveyed hatcheries. Two types of hormone injections PG (pituitary gland) and HCG (Human chorionic gonadotropin) were used for induced breeding. The rate of 1st dose of injection of PG varied from 1 to 2 mg/kg and HCG from 100-150 IU/kg and the rate of 2nd dose of injection of PG varied between 5 and 8 mg/kg. The incubation period and hatching rate in different fish species varied from 10 to 72 hours and 55% to 80%, respectively. The average total cost, gross return and net profit of the hatcheries were 0.667±0.798, 1.152±1.636 and 0.485±0.846 million BDT respectively.
