rohita), Mrigal (Cirrhinus mrigala) Silver carp (Hypothalmichthys
molitrix), Grass carp (Ctenopharyngodon idella) and Common

-
To facilitate quality production of
fish seed of culturable varieties.
-
To produce fish seed in those areas
where natural collection of fish seed is not possible and
arrange for distribution/marketing.

five operative months @ 5 runs per Rs. 4,16,000 month (1
run=sale of 51.2 lakhs of major carp @ Rs. 200/lakh + sale
of 12.8 lakhs of exotic carp spawn @ Rs. 500/lakh) i.e.,
(10,240 + 6400)*5*5
10. Economics of the Projects :
• Net Present Worth - Rs. 2.32 lakhs
• Benefit Cost Ratio - 1.24 : 1
• Internal Rate of Return - 40%
11. Other Information :
Process :
By resorting to induced breeding by
administering piruitary gland extract injection.
Steps :
i. Collection and storage of pituitary
glands :
Pituitary glands are collected from ripe
fish and preserved in absolute alcohol/acetone or by quick
freezing.
ii. Selection of breeders :
Breeders are identified and selected
based on their external characteristics such as weight,
quality, etc.,.
iii. Maintenance of breeders :
Breeders are maintained and stocked sex
wise in separate ponds one to two months prior to breeding.
iv. Dosage and administration of
injection :
Breeders are injected with different
doses of pituitary gland extract depending on body weight.
v. Spawning :
In cement ponds diagonally fitted with
water inlet pipes females and males are released for
spawning and fertilising the eggs.
vi. Incubation :
The fertilised eggs are led to incubation
pools for hatching and the hatchlings remain in the
incubation pond for three days.
vii. Rearing of Seeds :
Seeds are reared in earthen ponds and
feed of finely powdered groundnut/mustard cake is
administered.
viii. Harvesting :
Fries grow reasonably big (25-30 mm) in
two weeks and are harvested with drag net.
ix. Feed Requirement :
Mixture of finely powdered
groundnut/mustard oil cake/rice bran in equal proportion by
weight as under :
• 1 - 5 days - feeding four times the
total weight of the spawns
• 6 - 12 days - feeding eight times the
total weight of the spawns
• 13 - 14 days - no feeding
x. Few tips :
-
The location of a Hatchery should
ideally be on a sloping high land for economical
construction. If sloping land is available the floor level
of the spawn collection tank should be adjusted to the
ground level for draining out water by gravity.
-
The level of eggs transfer outlet
located at the centre of spawning tank should be about 10
cm. above the level of central overflow pipe at the top of
the hatching tank. This will enable complete transfer of
eggs from the spawning tank to use outside the tanks.
-
Overflowing water from the hatching
tank should not be passed on to the spawn collection tanks
but should be put to use outside the tanks.
-
Separate fresh-water supply lines
should be installed from the overheads water to
k to each tank i.e. spawning tank, hatching tanks and
spawn collection tanks in order to ensure independent
working of each.
-
Water spraying arrangements should be
provided for aeration and oxygenation in the three tanks.
-
Eggs transfer pipe should discharge the
water along with eggs into the hatching tank in between
the two walls of the hatching tank to avoid damage of
eggs.
-
The walls of the spawning tanks should
be provided with water inlet pipes installed in a diagonal
position to create a circular water flow during the
spawning period.
-
Where water flow is insufficient for
circulation, multiple-chambered hatching pools with paddle
wheels for circulation may be constructed.
Note :
• Margin of 10% is assumed, but the
actual margin will be as per the discretion of the banks.
• Interest rate of 15% is assumed for
both investment and working capital. However, the actual
rate will be as per banks' discretion.
• Similarly, the other economic /
financial parameters such as the repayment period, DSCR,
IRR, etc., may also vary depending upon the margin,
interest rate etc., taken into account by the bank
