Introduction to Fisheries and Aquaculture Technologies
1. Carp Breeding and Hatchery Management
01. Contact division/person/unit Freshwater Station, Bangladesh Fisheries Research
Institute (BFRI), Mymensingh.
02. Location of application Hatchery and freshwater pond complex all over the
country.
03. Key characteristics of the a. Facilitate quality mass seed production.
technology b. Facilitate selective breeding & line crossing technique
for better traits of progeny.
c. Reduce the risk of inbreeding & genetic deterioration.
d. Provide opportunities to develop carp hatchery
industry.
04. Production guidelines a. April-July is the right time for induced breeding offish.
b. Stocking of brood fish @ 1600-1800 kg/ha.
c. Supplementary feed @ 2 to 3% of body weight of fish
is essential 2 to 3 months prior to breeding.
d. Collection and selection of matured brood fish on the
basis of secondary sexual character & injection with
recommended hormone dose.
e. Fertilization, hatching and rearing of spawn in the
indoor hatchery facilities.
05. Risk involvement and a. Possibility of inbreeding to be avoided by changing
management in adopting the the brood population periodically.
technology b. Vigil is needed to protect against theft of brood stock.
c. Water quality is to be maintained to avoid disease
problem.
06. Impact of environment No adverse effect on environment.
07. Procedure of transfer Training of hatchery operators and managers.
08. Expected outcome a. Quality mass seed production can be ensured.
b. Create employment opportunity and making seed
production as rural industry.
Benefit and cost involvement For a private or public hatchery with a capacity of 100
kg spawn.
Totalcost: Tk. 80,000
Total revenue: Tk. 200,000
Net Profit: Tk. 120,000
09. Recommendations a. Proper hormone dose should be followed by hatchery
operators.
b. Hatchery operators should not use closely related
spawners.
c. Unplanned hybridization should be avoided.
d. Proper breeding plan and mass selection protocol
should be followed for better stock improvement.
