2. Fish is the cheapest and digestible animal protein and was obtained from natural sources from time
immemorial for consumption by human beings . Fish farming in controlled or under artificial conditions
has become the easier way of increasing the fish production and availability for consumption.
The marine fish landing in India during 2002 – 2003 was estimated at 2.64 million tonne , which is
.314 million tonne(13.5%) higher than that of previous year.
The technology developed for fish culture in which more than one type of compatible fishes are
cultured simultaneous .
This technology is known as composite fish culture..
Any perennial fresh water pond/tank retaining water depth of 2 meter can be used for fish culture and
the minimum level should not fall below one meter
Seasonal ponds utilized for short duration fish culture.

5. 2.POTENTIAL- The area under tanks and ponds available for warm fresh water
aquaculture is estimated to be 2.85million ha. The average productivity from ponds at
present is to the tonne of 2160kg/ha/year.
3.SUBSIDY- Subsidy is available for various items like pond development ,construction of
new ponds. Subsidy scheme implemented by the State Governments through FFDA’S
for different categories of farmers, details of may be obtained from concerned Fisheries
Departments.
4.ELIGIBLE BORROWERS- The following category of borrower are eligible to credit.
(a)An Individual (b)A Company (c)A Partnership farm (d)A Co-operative Society
(e)A Group of fish farmers
Training in fish farming is provided by the FFDA’S to the eligible borrowers.
5.RATE OF REFINANCE- NABARD provides refinance assistance for fish culture to
commercial banks, cooperative s and Regional Rural Banks.

6. Technical parameter that needs for composite fish culture
1 SELECTION OF POND- Selecting the pond is that the soil should be water
retentive, adequate supply of water is assured and that the pond is not in a
flood prone area.
2.POND MANAGEMENT - measures are required –
(a)Prestocking : In case of new ponds ,prestocking operation start with liming
and filling of the pond with water.
->Removal of weeds by manual/mechanical.
->Removal of unwanted and predatory fishes and other animals by sun drying
the pond bed , mahua oil cake@2500kg/ha meter
->Liming- The tanks are acidic in nature are less productive than alkaline
ponds . The following effects-
(a)Increases the pH .
(b)It increases the resistance of soil to parasites.
(c)Its toxic effect kills the parasites.
The normal doses of the lime ranges from 200 to250kg/ha . Actual dose based
on pH of the soil and water-

7.6-8.5 200
8.6-9.5 nil
SOIL (pH) LIME (kg/ha)
4.5-5.0 2,000

8.  Fertilization of the pond is intensifying fish culture by increasing
the natural productivity of the pond. A combination of both organic
and inorganic fertilizers may be used for best results.
(a) Organic Organic manure applied after a gap
of 3 days from the date of liming.
(b) Inorganic Inorganic fertilizer to be undertaken
after 15 days of organic manuring .
Requirement of nitrogenous and
phosphate fertilizers vary as per the
nature of soil fertility indicated.

10. STOCKING: The pond ready for stocking after 15 days of application of
fertilizer . Fish fingerlings 10 cm size (approx) used for
stocking@5000nos./ha.
Depending on availability of seed and market condition , stocking can be of 3
,4,or 6 species combination in the following ratio.

11.  (A) Supplementary feeding : Fishes need more food than available naturally
in the pond . Fishes can be fed with a mixture of bran and oilcake in equal
quantities daily . The feed should be placed on a bamboo tray and lowered
to the pond bottom or sprayed at the corners . The recommended feeding
rate is as under:
CULTURE PERIOD QUANTITY PER DAY (kg)
1. QUARTER 1.5-3
2. QUARTER 3 -6
3.QUARTER 6 - 9
4.QUARTER 9 - 12
TOTAL(for the year) 1,655 - 2700

12. ->Harvesting end of the 1st year ,when the fishes average weight of 750gmto
1.25kg. A production of 4 to 5 tons/ha can be obtained in a year.
