Abstract/ Executive Summary:

Carp hatcheries in Jessore region ranged from 0.20- 2.4 hectare. Most of the ponds of this area contained water round the year. Fifty per cent ponds have inlet system, 37.5% pond have outlet system and 12.5% have both system. About 70% hatchery owners dry their ponds before stocking after 2 to 3 years, 62.5% hatchery owners treated the water quality of the hatchery and pond in which 41.6% hatchery owners check the amount of dissolve oxygen and 37.5% check the pH value and 37.5% hatchery owners do not treat or test the amount of dissolve oxygen and pH value. A few numbers of hatchery owners have got the chance of training from BFRI, DOF and from other NGO's. 37.5% hatchery owners have training for 7-15 days from BFRI, DOF and NGO's. 50% hatchery owners have no training and only one percent hatchery owners have got the training opportunity from abroad.

Keywords: Brood stock management, Hatchery, Nursery

Location: Jessore, Mymensingh & Comilla

Start Date: 01-07-2001

End Date: 30-06-2002

Program Area: Seed Technology

Commodity: Fish

Objectives:

1. To survey the current brood management aspects, hatchery and nursery operation practices in Jessore area;

2. To study different parameters related to fish breeding in selected hatcheries;

3. To study different parameters related to fry production in selected nurseries; and

4. To identify the problems in brood stock management, hatchery and nursery operations and to suggest future studies/mitigating measures.

Methodology:

A survey was conducted on current brood management aspects, hatchery and nursery operation practices in Jessore area. Information was collected through personal interviews of the hatchery and nursery operators. Two hatcheries were selected at Chachra, Jessore to collect data on spawning of carp species. The variation of brood age, size, maturation, hormone application etc. and their effects on ovulation, fertilization were studied. Moreover, 3 nurseries from the same area were investigated to know the different aspects of nursery management of carps.

Funding Source:

1. Government

Budget: Fifty thousand

Total Budget (Tk.) : Fifty thousand

Achievement/Findings:

Jessore region, particularly Chachra area is pioneer in fish fry production of the country. With high intensification of both hatchery and nursery operations, about 60% of total national requirement of fish fry are met up from Jessore. However, with the increased production of fish fry, unexpected mass mortality during as well as in post hatchery operation, low quality of hatchery bred fry etc, have lately been reported. This might be due to negative selection of brood fish, mating of male and female from a close related population and unplanned hybridization, over stocking in nurseries, improper hatchery and nursery management etc. The findings of this study to the farmers will provide a better brood stock and nursery management which ultimately minimize the inbreeding problem in Jessore region.
