2. Introduction……
Shrimp is a valuable aquatic food resources high In
protein and command good export markets. The tiger shrimp
P.indicus and p.merguiensis are important candidate or
aquafarming.The seed requirement presently meet from the wild
and insufficient to meet growing demand. Hence there is a good
potential for hatchery production of shrimp seed.
The success of a shrimp hatchery depend on:
1.The choice of suitable site
2.Effectiveness and efficiency of the hatchery design
3.Experience of hatchery technicians
4.Efficiency of operational management.

3. .
1.Sea water supply: The sea water used in
hatchery should be clean,clear,and free from silt.
Suitable sites for hatchery are sandy and rocky shore
ecosystem.
2.Availability of spawners: Presence of
spawners at the vicinity of the proposed site is a
considerable advantage. It reduce the transportation
cost.
3.Availability of power sources: Electricity is
essential to run equipment and run other live
support system in the hatchery

4. 4.Freshwater supply: Freshwater is essential for daily
hatchery operation such as salinity adjustment, equipment
maintenance and other domestic use.
5.Accessibility:A hatchery should be sited in areas where
there are active shrimp farming operation so that the shrimp
larvae can be easily transported and distributed to the grow out
pond.
Basically there are two hatchery system adopted
1.The large tank hatchery: Developed in Japan,
2.The small tank hatchery: Developed in USA.
Hatchery Design and
construction

5. There are three determinants in designing a hatchery-
1.Target species
2.Production target
3.Level of financial inputs
Hatchery Design is aimed at achieving the production
target which determine the size of hatchery
Size of hatchery:-Based on the level of operation ,production
output and financial investment hatchery practice grouped into-
1.Backward hatchery :The seed production capacity 20 million per yr
2.Medium scale hatchery: The seed production capacity 50 million per
yr
3.Large scale hatchery: The seed production capacity more than 50
million per yr

6. Hatchery Facilities
1.Maturation Tank: The shape of the tank either be circular,
Rectangular or oval. The tank capacity with 5-40tons with
depth of 1.2-2m.Maintaning ablated shrimp in maturation
tanks would ensure a constant supply of gravid females.
2.Spawning tanks: The shape of the tank circular with a flat
or conical shaped bottom. The tank capacity with 50 lit to
1.5 tons. The tanks are used to temporality hold the gravid
females until spawning.
3.Larval rearing tanks: Two types of rearing tanks used to
rear the newly hatched larvae-
1.Small tank system-in southeast Asia with 3
tons capacity.
2.Larger tank system –in Japan with more
than50 tons capacity.

7. Contd.
4.Live food culture tanks: In mass cultivation
of live food organism size of the tank ranges
from 1-2 tons.
5.Water storage and filtration tank: The
water storage tank are normally elevated to
effectively distribute water by gravity to the
hatchery. When the water is turbid then
filter chamber is necessary .
There are two types of filter
system-
1.Gravity filter
2.Reversing filter

8. 6.Aeration:Aeration is essential during the entire larval rearing
process in maintaining DO concentration. it also help in
reducening ammonia content in the water.
7.Sea water supply and piping system:
If the water is relatively clear then the water can be pumped
directly into overhead filter tank and stored in storage tank .The
turbid water pumped first into sedimentation tank and the clear
water on the top is pumped into the filter tank .
Depending 0n the size of hatchery and
daily water requirement:
1.Small hatchery –Submersible pump
2.Medium hatchery-Centrifugal pump
3.Large hatchery - Centrifugal pump
Marine pumps

9. Lay out and Construction: once the project site is selected and
production target defined as an aerial survey of the proposed site will help
to determine the perimeter of the area. An aerial view would show
topographic characteristic such as river, mountain, shoreline etc.Layout of
the hatchery should provide a schematic design of the location and
integration of the various facilities such as building, bloodstock tank ,larval
rearing tank, nursery tank ,spawning tank ,pump house, air supply ,pump
house staff house,piping for water supply and drainage canals. the lay out
plan should include exact dimension locality shape and size of the said
facility . From the technical drawing owner can roughly estimate the cost of
the estimate .However estimation of construction cost should be done item
by item ,In total estimation labour cost should be included.

10. Conclusion......
In recent years the developed of shrimp
farming from a low level traditional subsistence
activity into a commercial enterprise has seen
tremendous transformation in the brackish water
sector. as shrimp is a valuable as well as high in
protein and command good export markets. About
10000ha of brackish water area is under shrimp
culture in India.
