This document discusses the economics of fish hatcheries and grow-out facilities. Key factors to consider when constructing a hatchery include the layout, type of fish to breed, and water supply and quality. Hatcheries produce juvenile fish to support aquaculture by transferring them to grow-out systems on farms. Grow-out facilities allow hatchery fish to reach harvest size. Hatcheries can help ensure consistent fish supply, support genetic improvement, and provide healthy, uniform fish seeds for farming when sited properly and run effectively.

3. INTRODUCTION
A 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.

4. 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.

6. Selection of site for Hatchery
• Topography
• Soil Quality
• Water supply & Quality
• Electricity
• Marketing
• Transportation of fish
Seeds.

7. Purpose
• 1. Out of season production
Supply can be further guaranteed by sourcing from hatcheries
in the opposite hemisphere i.e. with opposite seasons.
• 2. Genetic improvement
Genetic improvement can be mediated by selective breeding,
via hybridization, or other genetic
manipulation techniques.

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

16. 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.
