INTRODUCTIONA fish hatchery is a "place for artificial breeding, hatching

and rearing through the early life stages of animals,fin fish and shell fish in particular“.

Hatcheries produce larval and juvenile fish primarily to support the aquaculture industry where they are transferred to on-growing systems i.e. fish farms to reach harvest size. Some species that are commonly raised in hatcheries include shrimp, Indian prawns, salmon, tilapia and IMC. The U.S. Fish and Wildlife Service have established a National Fish Hatchery System to support the conservation of native fish species.

Important factors

• Following factors should considered before the construction of a fish hatchery.

1. Construction and lay out of fish hatchery and tanks.

2. The number of fish tanks and selection of the type of fish breeding.

3. Selection of suitable fishes for breeding.4. Conditioning procedures of tank.

Selection of site for Hatchery

• Topography• Soil Quality• Water supply & Quality• Electricity• Marketing• Transportation of fish Seeds.

Purpose

• 1. Out of season productionSupply can be further guaranteed by sourcing from hatcheries

in the opposite hemisphere i.e. with opposite seasons.• 2. Genetic improvementGenetic improvement can be mediated by selective breeding,

via hybridization, or other genetic manipulation techniques.

Outline What is quality from the Hatchery?– Healthy fish– Weaned to Pelleted Feeds– No defects– Uniform Size– Physiologically appropriate

Conclusion

Hatcheries, nurseries, and grow-out of fish such as groupers provide potential sources for the diversification of rural livelihoods and poverty alleviation. These also provide a solution to the degradation of the environment attributed to destructive practices in the live food fish trade.
