§1What this business is
The hatchery keeps brood fish in a 2 ha tank and breeds six species — catla, rohu, mrigal, silver carp, grass carp and common carp. Selected breeders are injected with pituitary gland extract and released into a circular cement spawning pool with flowing water. The fertilised eggs pass to hatching pools, where hatchlings stay for three days. Spawn is sold by the lakh to fish farmers; seed can also be reared in earthen ponds for two weeks to fry of 25–30 mm. The hatchery works for five months a year, with three months of preparation before and four months of pond care after.
Capacity: One spawning pool of 8 m diameter for 150–200 kg of brood fish and 3 hatching pools of 3 m diameter. The model sells 51.2 lakh major carp spawn and 12.8 lakh exotic carp spawn per run, 5 runs a month for 5 months.
§2Is it right for you?
Who it is for
A fisheries graduate or experienced fish farmer with a perennial tank and good water.
Who it is not for
Someone with no water source or no hands-on training in induced breeding.
Advantages
- Every fish farmer needs seed every year
- The same pools give 5 runs a month in the season
- Local seed saves farmers the losses of long transport
- Exotic carp spawn sells at ₹500 per lakh against ₹200 for major carps
Drawbacks
- Income comes in only five months of the year
- Brood stock of 5 tonnes must be fed and guarded all year
- Needs a steady flow of clean water and backup power
- Spawn prices in the model are old; local rates differ widely
Skills you need
- Selecting and maintaining brood fish
- Induced breeding — hormone dosage and injection
- Managing water flow, aeration and hatching
- Packing and transporting live spawn
Why difficulty 4/5: Induced breeding is skilled, time-critical work, and a single failure of water or power can kill a whole batch.
§3Market
Who buys
- Fish farmers and pond owners nearby
- Nursery pond operators who rear spawn to fry and fingerlings
- Fisheries departments and co-operatives

§6Schemes & subsidies
At about ₹6.04 lakh a Mudra loan can cover it. Fisheries departments also run their own hatchery subsidy schemes — ask the district fisheries office. The model was written for the Agri-Clinics and Agri-Business Centres scheme.
§7Money
How the investment is worked out: Capital cost ₹4,55,000 (renovation of a 2 ha tank, circular breeding pool and hatching pools ₹1,05,000; overhead tank of 5,000 gallons ₹50,000; shallow tube well, pumpset, generator and guard shed ₹1,20,000; 5 tonnes of brood stock ₹1,50,000; nets, hapas and equipment ₹30,000) + recurring cost for 3 preparatory months ₹43,800, 5 operating months ₹97,250 and 4 post-operating months ₹7,900. The page prints the total as ₹6,03,850; the printed lines add up to ₹100 more. The cost of the tank or land itself is not included.
Working capital: One full year's recurring cost (₹43,800 + ₹97,250 + ₹7,900) is built into the project cost; the largest items are feed for brood fish and wages. Margin 10% (₹0.60 lakh), bank loan ₹5.43 lakh at an assumed 15%, repaid in 5 years including 1 year's grace.

§9Risks — where people fail
- Breeding failure in a run
- Water shortage or power failure during hatching
- Disease or theft of brood stock
- Poor monsoon reducing farmers' demand for seed
