AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Tarpaulin ponds are the cheapest to set up, concrete ponds cost the most per fish but last longest, and earthen ponds cost least per fish where you have suitable land and water. In our labelled example, set-up cost per fish space is about ₦667 for tarpaulin, ₦2,833 for concrete and ₦400 for earthen, though feed and water management matter more to profit than the pond itself.
The three main options
Most Nigerian catfish farms use one of three pond types. Each suits a different situation: how much land you have, whether it holds water, how long you plan to farm and how much cash you have at the start.
- Tarpaulin (collapsible) pond
- A PVC liner on a metal or wooden frame, set on level ground. Quick to install and move.
- Concrete pond
- Block or concrete walls with a plastered, sealed floor and a drain. Permanent.
- Earthen pond
- A pond dug into the ground, best on clay soil near a water source. Larger and more natural, with algae and insects as extra food.
Cost compared (example)
The figures below are an example for comparison only. Prices depend on size, materials, labour and land. The stocking numbers are example planning figures; ask your hatchery or a fisheries extension officer what density suits your water supply.
| Tarpaulin | Concrete | Earthen | |
|---|---|---|---|
| Example size | 4m × 3m × 1.2m | 4m × 3m × 1.2m | 15m × 10m |
| Example set-up cost | ₦200,000 | ₦850,000 | ₦600,000 (excavation and drainage on suitable land) |
| Example fish per cycle | 300 | 300 | 1,500 |
| Set-up cost per fish space | ₦667 | ₦2,833 | ₦400 |
| Lifespan | A few years; shorter in direct sun | Many years with maintenance | Many years; banks need repair |
| Movable | Yes | No | No |
| Water changes | Frequent | Frequent | Less frequent; natural food |
| Harvesting | Easy: drain and net | Easy: drain | Harder: needs seine nets or draining |
Cost per fish space is set-up cost divided by fish per cycle: ₦200,000 ÷ 300 = ₦667; ₦850,000 ÷ 300 = ₦2,833; ₦600,000 ÷ 1,500 = ₦400. Spread over several cycles, each falls further. Lifespans are general descriptions, not tested figures; ask installers what warranty they give.
When each one makes sense
Tarpaulin
Best for beginners, renters and anyone testing the business. You can start in a compound, move if your lease ends, and add ponds as you grow. Keep it shaded, because sun weakens the liner, and set it on level ground free of sharp stones.
Concrete
Best for farmers who own the land and plan to farm for years. Concrete ponds are easy to drain, clean and harvest, and good for intensive feeding. Make sure the plaster is sealed and the pond is cured and flushed before stocking, since fresh concrete can harm fish.
Earthen
Best where you have clay soil, a stream or high water table, and space. Earthen ponds hold more fish per naira of set-up, and natural food in the pond can help growth. They need more land, are harder to secure against theft and predators, and are slower to harvest.
Hidden costs by pond type
- Tarpaulin: a shade structure, a level base, and a replacement liner when it wears out. Leaks can empty a pond overnight, so keep a repair kit.
- Concrete: plumbing for inlet and drain, curing and flushing time before stocking, and periodic replastering.
- Earthen: inlet and outlet structures, bank repairs after heavy rain, predator nets and stronger security.
- All types: pumping water, which costs power or fuel every week of the cycle.
Ask any installer to include plumbing, drainage and a base in the quote, since a pond price without them can be misleadingly low.
Pond type matters less than feed
Whatever pond you choose, feed will be your biggest running cost. A 2019 Nigerian feeding trial published by the GRÓ Fisheries Training Programme recorded feed conversion ratios from 1.35 to 2.81 depending on the feed, a range that changes cost per kg of fish far more than the difference between pond types. Farm-gate prices also move: a Nasarawa farmer told the News Agency of Nigeria in June 2025 that catfish sold for ₦2,800 to ₦3,500 per kg, down from ₦4,800 a year earlier.
So choose the cheapest pond that fits your land, water and plans, and spend the saving on good fingerlings and feed. See feed cost per kg of fish.
What to check first
- Does your land hold water? Dig a test hole and fill it.
- Where will clean water come from, and where will used water go?
- Do you own the land, or could you be asked to move?
- How will you guard the ponds at night?
- Can you drain and harvest easily?
Where Pryme fits
When you buy ponds or materials from installers, a Pryme Business Account keeps the farm's spending in one place, and a Savings Box can hold money for adding ponds later.

Questions people ask
Which fish pond is cheapest in Nigeria?
A tarpaulin pond is usually cheapest to set up. In our example it costs ₦200,000 for a 4m × 3m pond, against ₦850,000 for concrete of the same size.
Is concrete pond better than tarpaulin?
Concrete lasts longer and suits owned land; tarpaulin is cheaper and movable. Feed and water management affect profit more than pond type.
How many catfish can a tarpaulin pond hold?
It depends on size and water supply. Our example uses 300 fish in a 4m × 3m pond as a planning figure; confirm with your hatchery.
Is earthen pond good for catfish farming?
Yes, where the soil holds water and there is a good water source. It has the lowest set-up cost per fish in our example but needs more land and security.
