Fish Farming in India 2026 - Pond Setup, Cost & Profit

Freshwater carp farming in a pond is a steady, low-margin business that rewards good management: on our assumptions an acre of pond nets roughly ₹30,000 to ₹1.5 lakh a year on running costs alone, before counting the cost of building the pond. The national average yield has risen from 3 to 4.7 tonnes per hectare (about 1.9 tonnes per acre), and well-run ponds with feed and aeration reach 7 to 10 tonnes per hectare or more.

The government's PM Matsya Sampada Yojana (PMMSY) pays 40% of the unit cost (60% for women and SC/ST) for a new pond and for first-year inputs, but you still need land you own or a registered lease, a perennial water source and working capital for feed. This guide covers site, pond preparation, species and stocking, feeding, a cost-and-return table with stated assumptions, and the scheme amounts. For the wider picture see our fish farming page.

Will it work for you? Site checklist

• Water: a perennial source. TNAU says any pond retaining about 2 m of water can be used, and the level should not fall below 1 m. The PMMSY condition for new carp ponds is a minimum depth of 1.5 m.
• Soil: water-retentive clay or clay loam. Sandy or porous soils leak; polythene lining can be supported (see below).
• Flood safety: avoid flood-prone sites or build bunds above the highest flood mark.
• Land papers: PMMSY needs proof of ownership or, for a lease, a registered lease (the PIB note for the scheme refers to at least 7 years for this), free of encumbrance.
• Market and seed: know where fish will be sold and where good fingerlings come from before you dig.

Preparing the pond (TNAU / NABARD method)

1. Dry and clear. Dry the bed, remove weeds and unwanted or predatory fish by repeated netting, drying, or mahua oil cake at 2,500 kg per hectare-metre of water (toxic to fish, so stock only after it detoxifies).
2. Lime according to soil pH:

3. Manure. After 3 days, apply cow dung at 5,000 kg per hectare (about 2,000 kg per acre). After 15 days begin inorganic fertiliser (urea or ammonium sulphate and single super phosphate) in monthly doses decided by soil fertility; TNAU gives 30 to 60 kg urea and 40 to 70 kg single super phosphate per hectare per month depending on soil fertility (lower for richer soils). Avoid over-fertilising, which causes oxygen crashes.
4. Fill and wait about 15 days for natural fish food to grow (green or brown water), then stock.

Species and stocking

Composite (polyculture) carp farming puts species with different feeding zones in one pond: catla (surface feeder), rohu (column feeder) and mrigal (bottom feeder), sometimes with silver carp, grass carp and common carp. Catla and rohu sell best in most Indian markets, and TNAU's bankable model uses only Indian major carps.

• Stocking rate: TNAU/NABARD models use 5,000 advanced fingerlings (50 to 100 g each) per hectare, which is about 2,000 per acre. Reported intensive practice in Andhra Pradesh stocks 8,000 to 10,000 per hectare with feeding and aeration and gets 10 to 13 tonnes per hectare.
• Seed quality decides the crop. Buy from a government or reliable hatchery, check that fingerlings are active and uniform, transport in oxygenated bags during the cool hours and acclimatise to pond water before release.
• Tilapia and pangasius are covered by PMMSY inputs for freshwater aquaculture, but exotic species need state permission and strict compliance, so check with the fisheries department before choosing them.

Feeding and daily management

• Feed: rice bran and oil cake in a 4:1 ratio as supplementary feed (TNAU), or cotton seed cake and groundnut cake mixes; commercial pellets if you can afford them. Place feed in trays or bags lowered to the bottom or at fixed corners so fish learn to come and waste falls.
• Rate: 5 to 6% of body weight a day until fish reach about 500 g, then about 3.5% (TNAU). Reduce on cloudy days and when water is poor.
• Manuring: organic manure at about 1,000 kg per hectare monthly, alternating with inorganic fertiliser.
• Oxygen: the main cause of sudden fish death is low dissolved oxygen before dawn when algae are thick. If fish gasp at the surface early morning, stop feeding, change or add water, and run an aerator. An aerator and a standby power source are worth having for dense stocking.
• Check the growth of a sample by netting every 2 to 4 weeks, and watch for fish lice, gill problems and ulcers; consult the district fisheries officer or ICAR-CIFA for correct treatments rather than using random medicines.

Harvest

Fish grow to about 800 g to 1.25 kg in 10 to 12 months (TNAU). Many farmers do partial harvests once fish pass about 500 g, then restock. Harvest with repeated netting or partial draining; sell the same day or keep in clean holding water.

Cost and return per acre (illustrative)

TNAU's NABARD model dates from 2013 (costs ₹1.1 lakh per hectare running, 4 to 5 tonnes yield), so prices are out of date. The table below is our own arithmetic for one acre, for running costs only, excluding land and pond construction. Assumptions: fingerlings ₹8 each; feed ₹32 to ₹34 per kg with a feed conversion of 1.5 to 1.6 kg per kg of fish; farm-gate price ₹110 to ₹130 per kg (varies by region, size and species); replace with your own quotes.

Feed is about 50 to 60% of the cost, so feed price and conversion matter most. Working capital needed in the first year is roughly ₹1.4 to ₹3.7 lakh per acre. If you must dig a new pond, PMMSY's unit cost of ₹7 lakh per hectare is about ₹2.8 lakh per acre; after 40% assistance you pay about ₹1.7 lakh per acre, which takes a couple of good years of net income to recover. See the Kisan Credit Card scheme for working capital; KCC is available to fish farmers too.

PMMSY subsidy: what the official sheets say

PMMSY was launched in 2020 for an investment of ₹20,050 crore and the Finance Ministry extended it up to 2025-26 on the existing design (PIB, September 2025). We could not find an official notification on its structure beyond March 2026, so confirm current availability with your District Fisheries Office.

Hill states with higher costs may set higher ceilings (J&K lists up to ₹8.40 lakh per hectare for new ponds). Women and SC/ST applicants can get up to 60% of the project cost. To apply, prepare a detailed project report (species, capital and recurring costs, land proof, timeline), and submit it to your District Fisheries Office; register on the National Fisheries Digital Platform launched in September 2024 for scheme access, credit and insurance. PM-MKSSY (2023-24 to 2026-27) also promotes aquaculture insurance. Because the subsidy is usually back-ended or released in instalments, you will need to arrange the beneficiary share in advance.

Biofloc and RAS: only with training and reliable power

PMMSY has supported more than 22,000 RAS, biofloc and raceway units. Biofloc fits small plots and uses little water, but it needs constant aeration, electricity backup and close monitoring; a power cut of a few hours can kill a full tank. Try it only after training at a fisheries college or KVK, and make sure feed supply and market are fixed.
