Abstract/ Executive Summary:

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.

Location: 13 hatcheries of Rajshahi district, Bangladesh

Start Date: 00-03-2013

End Date: 00-12-2013

Program Area: Animal Health and Management

Commodity: Fish

Objectives:

To find out the way to standardize the fish hatchery sector.

Methodology:

Study area and duration: This study deals with 13 hatcheries of Rajshahi district, Bangladesh. The study was carried out over a period of 10 months from March to December 2013. Rajshahi district is situated in the southwestern part of Rajshahi division and lies between 24°6¢N and 25°13¢N latitudes and between 49°02¢ and 49°21¢E longitudes. Data collection: For data collection, a reasonable size of sample was considered. A survey schedule was prepared and the data on fry production, induced breeding and cost profit were collected by survey and interview; other relevant data were collected from district and Upazila fishery offices. Data analysis: All the collected data were checked, summarized and scrutinized carefully and analyzed by MS Excel.

Achievement/Findings:

The production quantity of fish fry and profit of government hatcheries was less than the private hatcheries in pursuance of production capacity. To get the maximum quantity and high quality fry, the proper doses of hormone injection and use of quality brood fishes should be maintained. Emphasis should be given on expansion of hatchery facilities to supply high quality and quantity of fish fry required to support aquaculture development. More future works are necessary on different aspects of fish fry production. The government and NGOs should provide all modern facilities in connection with the quality fish fry production in Bangladesh.
