Catfish Farming in Nigeria 2026: How to Start, Pond Setup, Costs and a Profit Worksheet

📌 Quick answer (checked 1 November 2026): Catfish (Clarias gariepinus) is Nigeria’s main farmed fish. FAO’s FISH4ACP programme puts national catfish output at about 1 million tonnes a year from roughly 300,000 grow-out farmers (June 2026). Feed is 78–85% of operating costs on most farms, so your profit depends mostly on your feed price, your feed conversion ratio (FCR) and how many fish survive. Input prices change from month to month and from state to state, so this guide has no fixed “₦ profit per cycle” figure. Instead it gives you a worksheet: fill in your own written quotes for fingerlings, feed and labour and it shows your break-even selling price per kilogram.

If you searched for how to start catfish farming in Nigeria, you want three things: whether the market is real, how to set up and run a pond, and whether the numbers work. The market is real. The Minister of Marine and Blue Economy said in October 2025 that domestic output meets only about 38.9% of the 3.6 million metric tonnes of fish Nigeria needs each year, which leaves a supply gap of more than 2.2 million tonnes. No honest guide can promise what you will earn, though. Earlier versions of this page included a fixed profit calculator built on unsourced prices. We have replaced it with a method you can run on your own figures.

The Nigerian catfish market in figures

FAO’s 2023 sector story also explains why so many farms struggle. Production grew by more than 20% a year between 2005 and 2015 and then declined from 2016, mainly because feed prices rose. Farmers name capital and access to finance as their main constraints. In 2026 FISH4ACP reported that a USD 550,000 programme of farm data and best-practice training for 500 farmers across five clusters roughly doubled farm value added. It raised production by 5%, cut costs by 10% and paid for itself in under eight months. The takeaway for a new farmer: record-keeping and feed efficiency affect profit more than pond size does.

Step 1: Decide your scale and pond type

For a first cycle, start small, learn the system and only then expand. The three common pond types each have trade-offs. Get construction quotes from at least two local builders or suppliers. Costs vary a great deal with location, soil, water source and materials.

Before you build, confirm three things. You need a reliable water source (borehole, well or stream) that you can change partly at short notice. You need a drainage route that will not flood neighbours. You need security against theft and predators. If you plan to grow beyond a backyard, register a business name with the Corporate Affairs Commission (see our CAC business name guide). Lenders and large buyers usually ask for one.

Step 2: Buy good fingerlings or juveniles

Poor seed is a frequent cause of a failed first cycle. FAO notes that Nigeria’s catfish boom began in the 1990s once government hatcheries made fingerlings widely available. Today most seed comes from private hatcheries. Practical checks:

• Visit the hatchery and look at its broodstock and holding tanks.
• Buy fish of one uniform size. Mixed sizes lead to cannibalism.
• Ask for the hatch date and average weight, and count a sample yourself.
• Your state Ministry of Agriculture fisheries unit or the ADP extension office can usually point you to established hatcheries.
• Quarantine new stock away from existing fish for a few days and watch for sores, abnormal swimming or heavy mucus.

Buying larger juveniles instead of small fingerlings costs more per fish. It shortens your grow-out period and exposes you to fewer of the fragile early weeks, which helps beginners.

Step 3: Run the grow-out cycle

The figures below come from FAO’s technical manual on African catfish production (2015). Parts of that manual describe intensive tank systems, so treat stocking numbers as an upper limit, not a target for a beginner’s pond.

Daily and weekly routine

1. Feed to appetite, at set times. Floating pellets let you see how much the fish actually eat. Remove uneaten feed, because it wastes money and fouls the water.
2. Weigh a sample every two weeks. Net 20–30 fish, weigh them together and divide by the number to get the average weight. Multiply by your estimated fish count to get total biomass. Adjust the daily ration to match.
3. Keep a farm record book. Note feed used, deaths, sample weights and water changes. You need these records to calculate your real FCR. FISH4ACP’s 2026 results came largely from this kind of data use.
4. Change water regularly. Change part of the water when it smells, turns dark or the fish gulp at the surface for long periods.
5. Plan the sale before the harvest month. Fish held past market size keep eating feed for little extra profit.

Step 4: Prevent disease rather than treat it

FAO’s manual lists bacterial infections (Aeromonas, Pseudomonas), parasites (Trichodina, gill and skin flukes) and fungus (Saprolegnia) as common problems. Prevention is mostly clean water, sensible stocking density, careful handling and quarantine of new fish. FAO describes short salt baths as one option for external parasites. Antibiotics and chemical treatments carry residue and resistance risks, and some chemicals are not permitted in food fish in many markets. Get a veterinarian or a state fisheries officer to diagnose the problem before you treat. Never sell fish still inside a drug withdrawal period.

Step 5: Work out your own cost and profit (worksheet)

This section is illustrative arithmetic, not a price guide. It uses example quantities to show the method. Every naira figure must come from your own written quotes, collected in the same month you stock.

A. Estimate what you will harvest

B. Estimate the feed you will need

Feed needed ≈ weight gained × FCR. Starting weight is small, so for a rough plan use the harvest weight. At an assumed FCR of 1.5, the example needs 1,020 × 1.5 = 1,530 kg of feed, about 102 bags of 15 kg. At FCR 2.0 it needs 2,040 kg, one-third more. That one assumption changes your largest cost more than anything else.

C. Price it with your quotes

Sanity check: FAO says feed is 78–85% of operating cost on most Nigerian farms. If feed comes to well under 70% of your T, you have probably left something out. If it is above 90%, check the feed price or your FCR assumption.

D. Find your break-even and margin

• Break-even price per kg = T ÷ harvest weight. In the example, divide T by 1,020 kg.
• Gross profit = (harvest weight × the price your buyer has actually agreed) − T.
• Add a share of pond construction (build cost ÷ the number of cycles you expect the pond to last) to see the true profit per cycle.

Then run the sheet again with survival at 70% and FCR at 2.0. If the business only works under the best-case assumptions, reduce your stocking number or improve your setup before you buy fish.

Where to benchmark selling prices

The National Bureau of Statistics publishes a monthly Selected Food Price Watch with average retail prices per kg of fresh, dried and smoked catfish. The latest edition listed on the NBS microdata portal when we checked covers May 2026. These are retail prices, so your farm-gate price will be lower. Use them as a ceiling, not a forecast, and get buyer quotes in writing.

Step 6: Choose how to sell

FAO’s 2023 case study of the Eriwe fish farm village near Ijebu-Ode shows the cooperative route. Nearly 600 farmers produced about 2,000 tonnes in 2022, moved into processing and cut out intermediaries so they could negotiate prices directly. If you are farming near others, consider joining or forming a cluster.

Selling abroad: the rules, not a promise

Earlier versions of this page made specific claims about diaspora export margins that we could not verify, and we have removed them. The verified part is the paperwork. The Nigerian Export Promotion Council lists the Federal Department of Fisheries as the competent authority that issues health certificates for exports of fish and fishery products. NAFDAC issues health certificates and certificates of manufacture and free sale for processed and semi-processed foods. The importing country also has its own rules on residues, labelling and approved establishments. Before you invest in export, contact both agencies and the buyer’s import authority in writing. Export is a stage for an established, consistent processor, not a first-cycle plan.

Funding a start

Most beginners fund the first cycle themselves. In 2025 FAO’s FISH4ACP launched an input-finance initiative for catfish farmer clusters (the launch was held at a cluster in Ijebu-Ode). Credit runs through partner lenders including the Bank of Industry and FCMB, and FAO reported that about 40 farmers had accessed roughly USD 105,000 at launch. FAO did not publish eligibility rules, so ask the participating banks or your cluster or cooperative directly. For other options, see our guides to business loans without collateral and starting an agribusiness with low capital. If you are comparing species, read our tilapia farming guide.

Frequently Asked Questions

How much does it cost to start catfish farming in Nigeria?

There is no single honest figure, because pond, fingerling and feed prices differ by state and change monthly. Use the worksheet above with written quotes. Feed will be most of your operating cost: FAO puts it at 78–85% on most farms (June 2026).

How long does catfish take to reach market size?

FAO’s manual gives roughly 34–46 weeks from hatching to about 1 kg under good conditions. If you buy fingerlings or juveniles, your own grow-out is shorter. Ask the hatchery the age and weight of the fish you are buying.

How much profit can I make from 1,000 catfish?

That depends on survival, harvest weight, FCR, your feed price and the price your buyer pays. Work out your break-even price per kg (total operating cost ÷ kg harvested). Compare it with written buyer quotes and the NBS food-price benchmark before you stock.

What FCR should I aim for?

FAO reports 0.9–1.4 in well-run intensive systems. Many small farms record higher figures. Track feed used and weight gained in a record book, and improve your FCR by feeding to appetite, grading fish by size and keeping water clean.

Do I need a licence to farm catfish?

Requirements vary by state. Check with your state Ministry of Agriculture fisheries unit and local government. To sell processed fish abroad you need certificates from the Federal Department of Fisheries and/or NAFDAC, plus whatever the importing country requires.
