Value Chain Analysis · Pillar 06

A kilogram of tilapia roughly doubles in price from the farm gate to the retail slab, and roughly triples for the same size of fish in a supermarket, at 2016 prices. Little of that markup reaches the farmer, who takes the production risk. Value leaves the farm in two directions: upstream to imported feed, and downstream to the traders who move the fish. Few businesses have yet built the processing and cold chain that could earn more of it. That thin middle, with little industrial processing of farmed fish and little organised cold chain, is the biggest opening in the sector.

Ghana’s tilapia chain is short and simple: seed and feed suppliers feed a set of farms, the farms sell to aggregators and traders, and the traders sell fresh whole fish to consumers. There is almost nothing in between. IFPRI researchers described the chain as relatively short and simple, like those in Egypt and Zambia.¹

A short chain gets fish to the plate quickly and cheaply. It also means little processing, portioning, freezing or branding happens, so few businesses earn the money that work would bring.

What this shows

The chain runs from seed and feed, through the farm, to a thin, informal middle of traders and smokers, and on to the plate. Value is lost in the gap in the middle.

🔍 WHAT THIS MEANS

Most of the money in the chain sits at its two ends. At the input end, feed takes most of the cost. At the downstream end, processing and cold chain would earn most of the value if someone built them. The farmer sits between the two ends, taking the biological risk and the thinnest margin. The best openings move a business from the farm toward feed at one end or toward processing and cold chain at the other.

🐟 Link by link: who operates each step 🐟

Link one: seed and feed

Most of the money is decided before a single fish is stocked. Feed is the biggest input, at about three-quarters of the cost of raising fish in cages,⁴ and one local mill has long dominated supply. In 2015 Raanan was the only specialised local aquafeed mill, producing about 25,000 tonnes a year for Ghana at full capacity;² by 2017 it produced about 30,000 tonnes and sold about 70 percent of that in Ghana.⁵ Imported brands and small local mills supply the rest. Imported feed, from the likes of Coppens, Aller Aqua and Skretting, runs about 30 percent dearer than local, and port taxes and fees add 20 to 30 percent to the cost of imported feed.¹ Feed price is therefore shaped by a few suppliers and by an exchange rate the farmer cannot control, and it is the main reason a kilogram of tilapia cost about US$1.51 to produce in Ghana against US$0.78 to 1.29 in Bangladesh, Egypt and China.⁶ Feed decides how competitive the sector is.

Seed is the second input, and its quality affects every later stage. Hatcheries produced about 382.8 million fingerlings in 2024,⁷ but disease can travel with the fingerlings. About 63 percent of farms sampled on the lake sourced broodstock or fingerlings from a farm that tested positive for ISKNV.⁸ Fingerlings are a small share of farm cost, 6.62 percent on small-scale cage farms in 2022, yet their quality decides survival and therefore whether the cage ever earns anything.⁴Cheap, unscreened seed can cost a whole batch. Pillar 1 covers the biology of seed. In business terms, feed and seed decide the farmer’s economics, few suppliers provide them, and both are business openings.

Feed is the sector's biggest cost and its most concentrated market.

🎯 OPPORTUNITY

An independent feed mill is the strongest entry point in the chain. Because feed is about three-quarters of a cage farmer’s cost and one local mill has long dominated supply, cheaper, reliable local feed improves the economics of every farm at once. In 2015 a business case costed a 30,000-tonne mill at about US$4.2 million, assuming a gross margin of about US$250 a tonne.²

A certified hatchery sells disease-screened seed into a market that produced 382.8 million fingerlings in 2024,⁷ while cutting the disease that unscreened seed spreads. Small on-farm feed milling is a smaller version of the feed-mill business. Local producers undersold Raanan by 10 to 35 percent in 2021 and 2022.⁹

The live-catfish trade

Whole catfish fetched about GH¢40 a kilogram at the farm gate in September 2026; sold live, it avoids the cold-chain problem.

Link two, production: two parallel chains, plus the live-catfish trade

Production is three overlapping businesses, and entrants who confuse them plan badly. The tilapia side runs on two parallel chains. At the top sit a few large integrated farms, then medium farms, then several hundred small-scale cage farms: around 2016 the Fisheries Commission counted ten large and eight medium tilapia farms,¹ and a 2022 survey drew on a list of 256 small-scale cage farms.⁴ A separate live-catfish trade runs alongside. The two largest farms are fully integrated: they own their hatcheries and their cold stores, they grade and gut before sale, and they reach the market through their own channels. Tropo Farms, the leading tilapia producer in West Africa, employs about 917 people and supplies through about 3,000 mostly women traders, and is scaling toward 30,000 tonnes on a US$10 million AgDevCo loan.¹⁰ It is an example of a large integrated anchor farm. Smallholders work differently. They buy seed and feed from others, sell fresh whole fish at or near the farm gate, and depend on traders to move it. They farm the same lake and the same fish, but run very different businesses.

Running alongside both is the live-catfish chain, which works very differently from tilapia. Catfish is sold live into the point-and-kill trade, bars and roadside spots where the customer picks a live fish and it is killed and grilled to order, at a farm-gate pool price of about GH¢40 a kilogram for whole catfish in September 2026.¹¹ Because it is sold live or smoked, it avoids the cold-chain problem that hurts fresh tilapia, and it earns a higher price from bars and restaurants. In European tank systems African catfish yields from about 300 kilograms (Hungarian flow-through) to 1,500 kilograms (Dutch recirculating systems) a cubic metre a year at a feed conversion of about 0.9 to 1.4, reaching 1.1 to 1.6 kilograms in 30 to 50 weeks,¹² so a live-catfish grow-out supplying urban bars is a separate business with its own market.

📡 MARKET SIGNAL: INTEGRATION IS WINNING

The sector is moving toward large integrated farms. Tropo already runs its own hatchery, grow-out, cold storage and a network of about 3,000 traders, and its 2024 loan is financing a modern processing facility.¹⁰ An entrant will rarely beat a large integrated farm on its own terms. Supplying it with seed, feed or out-grown fish, or copying its model at smaller scale, is a workable position.

Link three, aggregation: the traders who move the fish

Between the farm and the plate sits a layer of aggregators and traders, and it does much of the work in the chain while also drawing many farmer complaints. Aggregators pick fish up at the farm gate, and the degutting, descaling and icing is done by small traders and cold stores rather than by any organised processor.¹ The trade is large. Tropo alone reaches the market through about 3,000 traders, most of them women.¹⁰ These traders move a perishable product from scattered cages to scattered markets. They work informally, on ice and by road, and take a large share of the gap between farm and retail prices.

Farmers feel this as the cost of the middlemen. In the profitability survey, farmers named the high cost of middlemen, the distance from farm to market, and poor transport among their top constraints,⁴ and during the COVID-19 disruption 56 percent of pond farmers surveyed had difficulty selling their fish.⁶ The farmer has no alternative route to the buyer, no cold chain of their own, and no shelf-stable product, so they accept the farm-gate price and the trader keeps the difference. This lack of choice creates the opening for cold-chain aggregation.

🐟 The price ladder from farm gate to supermarket 🐟

The tilapia price ladder from farm gate to wholesale to retail to supermarket, per kilogram — Figure 17 The tilapia price ladder: farm gate to wholesale to retail to supermarket, per kilogram

Source: Ragasa et al., Table 3.2 (2016 prices).¹

A kilogram of tilapia roughly doubles in price from the farm gate to the retail slab, and roughly triples for the same size in a supermarket, at 2016 prices. Most of that markup is captured after the fish leaves the farm.

An IFPRI survey tracked a kilogram of regular and size-1 tilapia up the ladder at 2016 prices: about GH¢9 to 11 at the farm gate, GH¢11 to 13 wholesale, GH¢18 to 25 at cold stores, wet markets and roadside outlets, and about GH¢29 in a supermarket, where larger size-3 fish reached GH¢40.¹ Retail was roughly double the farm gate, and supermarkets charged about three times the farm gate for the same size of fish.

Prices are now about four to five times higher, allowing for the 2026 price being for gutted fish: the Chamber of Aquaculture Ghana’s farm-gate pool price for gutted 300 to 400 gram tilapia was GH¢50.55 a kilogram in September 2026, up about 16 percent since January,¹³¹¹ and four medium fresh tilapia cost GH¢100 in an Accra market in April 2026.¹⁴

🔍 WHAT THIS MEANS

The doubling from farm gate to retail pays for moving a perishable fish through an informal chain. Between the farm and the shelf the fish is only iced, transported and re-sold in small lots. Few operators fillet it, freeze it, smoke it to export grade or brand it, and as much as GH¢8 a kilogram went to transport and traders’ margins at 2016 prices.¹ A business that processes fish at that stage could earn a margin that today goes on handling.

🐟 Who earns what, and why the farmer earns least 🐟

The farmer carries the biology, the disease, the feed-price shock and the mortality risk, then sells a fresh whole fish at the bottom of the ladder and hands the rest of the value to others. Upstream, about 77 pesewas of every cedi a small-scale cage farmer spends goes on feed,⁴ part of it on imported brands and imported ingredients. Downstream, the roughly two-times farm-gate-to-retail markup is captured by traders and retailers who pay for ice, transport and small-lot selling. The farmer is squeezed between the two.

Farming itself is profitable: the average small-scale Lake Volta cage farm surveyed in 2022, with one to ten cages, returned about GH¢127,261 a cycle on revenue of about GH¢395,231, a benefit-cost ratio of about 1.47 and a return on investment of about 47 percent,⁴ and an earlier survey of 97 farms found an average return on cost of about 36 percent per six-month cycle.¹⁵The farmer’s profit is real, but it swings with feed and disease. Safer and larger margins sit at the two ends of the chain, where the farmer has no part. An entrant who wants a lasting margin should consider owning part of feed, seed, cold chain or processing, where most of the value sits, before adding another grow-out cage.

📡 MARKET SIGNAL: BACK THE RESILIENT NODE

Because grow-out looks profitable on paper, pooled investment schemes in this sector promised backers well above 80 percent a year and went insolvent.¹⁵ For value-chain investors, the safer choices are feed, seed, cold chain and processing. A borrowed-money bet on grow-out, the riskiest link, is the weaker choice.

A layer of the chain that is only now being built

Ghana produced about 121,809 tonnes of farmed fish in 2024, up from about 116,108 tonnes in 2023,⁷ and tilapia is close to 80 percent of it,¹⁶ yet little farmed fish is processed industrially, most is sold fresh on ice, and the government calls post-harvest losses a major challenge.¹¹⁷ Most processing of farmed fish is small-scale smoking, frying, salting and drying, much of it by women, and industrial capacity is only now being built: Tropo’s 2024 loan finances a modern processing facility.¹⁰ This thin processing and cold-chain layer is the missing middle.

The missing middle has three expensive consequences. First, loss: with little cold chain to hold a glut, fish that cannot be sold fresh is dumped cheaply or spoils. Second, import vulnerability: because there is no shelf-stable, portioned local product, cheap frozen imports hold the low-income, no-fridge market that fresh local fish cannot reach, with about 254,800 tonnes of frozen fish worth about US$171.9 million in 2024, most of Ghana’s fish imports by value, with no frozen tilapia recorded.¹⁸ Third, lost value: few producers reach the high-value markets. Women smokers who met EU safety standards could earn around GH¢100 a kilogram of smoked fish in 2022, roughly ten times the price in local markets,¹⁹ while farmed tilapia is mostly sold fresh, at about GH¢50.55 a kilogram gutted at the farm gate in September 2026.¹¹

🎯 OPPORTUNITY

Investors have started to fill the missing middle. Tropo’s 2024 loan is financing a modern processing facility,¹⁰ a sign that investors expect returns from processing and cold chain.

A processing and cold-chain business turns a fresh commodity that fetched about GH¢50.55 a kilogram gutted at the farm gate in September 2026¹¹ into shelf-stable, portioned, branded product: fillets, vacuum packs and export-grade smoked fish. It cuts post-harvest loss and lets a local brand hold the shelf-stable market that frozen imports own today.

Cold-chain aggregation needs less capital: branded refrigerated vans and cold stores that capture part of the farm-gate-to-retail spread while cutting loss, the model Tropo already runs.

🎯 OPPORTUNITY: THE DIGITAL MISSING MIDDLE

The missing middle is also a digital opening. A cold-chain aggregation platform that matches farmers to buyers, schedules refrigerated pick-up and tracks the fish from cage to shelf can earn part of the two-times spread and cut loss, using software as well as equipment.

Export sales depend on traceability. Because export buyers, the EU above all, take fish only from approved and traceable establishments, digital batch traceability and cold-chain records are a low-cost first step for a processor that wants to reach the export-grade smoked and fillet markets. Pillar 8 lists the tools available now.

What this shows

The low-capital openings with a wide gap are advisory, seed and cold chain; feed milling and processing fill a wide gap but need more capital.

The best positions sit at the two ends of the chain

The openings can be ranked by their effect and by how much capital they need. The best positions sit at the two ends of the chain: feed and seed upstream, processing and cold chain downstream. Another undercapitalised grow-out cage in the middle faces crowding and thin margins.

🐟 Opportunity: the value-capture openings, ranked 🐟

01

An independent or premium feed mill. It improves every farm's economics at once, and would cost about US$4.2m for a 30,000-tonne mill at 2015 costs.

02

A processing and cold-chain plant making fillets, vacuum packs and export-grade smoked fish, cutting post-harvest loss and holding the shelf-stable market from imports.

03

A certified improved-strain hatchery, selling disease-screened seed into a market of hundreds of millions of fingerlings a year while cutting the disease that unscreened seed spreads.

04

Cold-chain aggregation. Branded refrigerated distribution that captures the two-times farm-to-retail spread and cuts loss, at lighter capital than a full plant.

05

A dedicated live-catfish supply chain into point-and-kill bars, avoiding frozen-import competition entirely.

06

Import-substitution frozen or portioned tilapia, taking the shelf-stable segment that informal frozen imports hold today.

07

A contract-farming or out-grower model around a feed-and-processing anchor, locking in supply and stabilising smallholder margins, the Tropo network at smaller scale.

🐟 The risks that sit inside the value chain 🐟

Fresh Ghanaian tilapia laid out in the open sun with no ice at a lakeside landing, documentary photograph

Thin cold chain, heavy post-harvest loss

VERY HIGH

What it is

There is little organised cold chain for farmed fish, so a glut cannot be held and moved. Fish is iced and rushed to market or it is lost, which forces farmers to dump at low prices and wastes a large share of what they raise.

Evidence

Farmed tilapia is sold mostly fresh on ice, with little cold storage to hold a glut, and shelf-stable forms are small-scale smoked, salted and dried fish.¹³

Who it hits

Smallholders hardest, who have no storage of their own and must sell fresh whatever the day's price; also the wider sector, which loses fish in every glut.

How to manage it, and the opening

Build or buy into cold storage and refrigerated distribution. The matching opening is a cold-chain aggregation business that earns part of the farm-to-retail margin while cutting loss.

A Ghanaian fish farmer holding fresh whole tilapia, with little local capacity to fillet, freeze or export-smoke it, documentary photograph

Little industrial processing

HIGH

What it is

Because industrial filleting, freezing and export smoking of farmed fish is only now being built, the farmer is stuck selling fresh whole fish at the bottom of the price ladder and cannot reach the high-value forms that earn many times more.

Evidence

Little farmed fish is processed industrially and most is sold fresh on ice,¹ while smokers who met EU safety standards earned around GH¢100 a kilogram in 2022, roughly ten times the local market price.¹⁹

Who it hits

Every producer who wants a lasting margin above the fresh-fish price, and the sector's export plans.

How to manage it, and the opening

Add the processing the chain lacks. Tropo's 2024 modern-processing investment shows that lenders will now fund processing, and early entrants can set the standard.

Stacked sacks of aquafeed at a Ghanaian lakeside store, documentary photograph

The single-feed-supplier squeeze

HIGH

What it is

Feed is the largest cost in the chain and one local mill has long dominated supply, so feed price and availability often decide whether a farm survives. A price rise or supply gap upstream hits every farmer at once.

Evidence

Feed is about 77 percent of small-scale cage cost,⁴ Raanan was the only specialised local aquafeed mill in 2015,² imported feed costs about 30 percent more, and port taxes and fees add 20 to 30 percent to imported feed.¹

Who it hits

Every farmer, but hardest on smallholders with no buying power and no ability to hedge feed price.

How to manage it, and the opening

Lock feed supply and price where possible, buy through groups, and give priority to local feed. The opening is a feed mill. The pressure feed prices put on farmers is the business case for a new mill.

A newcomer adding another crowded grow-out cage on Lake Volta, documentary photograph

Undercapitalised entry at the wrong node

MEDIUM

What it is

Most newcomers start with a few grow-out cages. This is the most crowded and riskiest part of the chain, with thin margins, and undercapitalised newcomers often fail there. Value concentrates at feed, seed, cold chain and processing.

Evidence

The farmer captures the least of the roughly two-times farm-to-retail markup, carries the feed and disease risk, and past pooled investment schemes promising well above 80 percent a year went insolvent.¹⁵¹

Who it hits

First-time entrants and small investors who back a cage because it is the visible part of the business.

How to manage it, and the opening

Enter at a sturdier link in the chain, or enter grow-out only with a real edge (secured feed, contracted offtake, a cost advantage). Base the investment on the numbers.

🐟 Key takeaways 🐟

01

At 2016 prices a kilogram roughly doubled from farm gate to retail and about tripled in a supermarket, and the farmer earned the smallest margin.

02

Value leaks two ways: upstream to feed, about three-quarters of farm cost and partly imported, and downstream to traders, who add only ice and transport yet take much of the two-times markup.

03

The missing middle, little industrial processing and little cold chain, is the biggest opening in the sector.

04

Smoked fish that met EU standards sold for around GH¢100 a kilogram in 2022, about ten times the price in local markets.¹⁹

05

Enter at feed, seed, cold chain or processing, where margins are larger. Tropo's move into processing shows where investors are heading.

Written for each reader

🐟 Practitioner intelligence 🐟

Hover any card to pause and lift it.

For students

Think of fish farming as a chain and ask who earns the margin at each step. Trace one kilogram of tilapia from a Volta cage to a supermarket shelf and write down who earns what at each rung; you will see the farmer earns least and takes the most risk. Then study the two ends where margins are larger, feed upstream and processing downstream, and build skills for one of them. An internship or small job with an aggregator, a cold store, a smoker or a feed producer shows you more about where money is made than working a grow-out cage.

For entrepreneurs

Think twice before starting with grow-out cages, the most crowded and riskiest part of the chain, with thin margins. Consider a feed mill, a hatchery, cold-chain aggregation, live-catfish supply, or a small processing and smoking operation. Many newcomers fail because they enter the most visible part of the business, the cage, while the lasting margin sits at feed, seed, cold chain and processing. If you do enter grow-out, do it only with a real edge: secured feed, contracted offtake or a clear cost advantage, and plan to add feed, seed, cold chain or processing as you grow.

For investors

Choose the link in the chain with care, because the farmer carries the risk and captures the least of the farm-to-retail markup, and pooled grow-out schemes have already gone insolvent chasing returns the farms could not pay. Back feed, seed, cold chain and processing, where margins are larger and where Tropo's processing investment shows the missing middle starting to fill. Diligence should ask where feed comes from, whether cold chain exists, and whether the venture owns one of these stronger links or is another cage exposed to feed and disease.

For ecosystem actors

Public support does most good when it helps build the missing middle: processing, cold chain and competitive feed. Each tonne processed locally keeps value in Ghana that now goes abroad, and each cold store cuts post-harvest loss. Tie public support and the Fisheries and Aquaculture Development Fund created by the Fisheries and Aquaculture Act, 2025 (Act 1146), to processing, cold-chain and feed capacity ahead of more grow-out cages, and measure success as the share of farmed fish that is processed, cold-stored and sold as a durable local product. Avoid subsidising more production into a chain that cannot store, process or move it.

Back feed, seed, cold chain and processing, where margins are larger and where Tropo's processing investment shows the missing middle starting to fill. Diligence should ask where feed comes from, whether cold chain exists, and whether the venture owns one of these stronger links or is another cage exposed to feed and disease.

For ecosystem actors

Public support does most good when it helps build the missing middle: processing, cold chain and competitive feed. Each tonne processed locally keeps value in Ghana that now goes abroad, and each cold store cuts post-harvest loss. Tie public support and the Fisheries and Aquaculture Development Fund created by the Fisheries and Aquaculture Act, 2025 (Act 1146), to processing, cold-chain and feed capacity ahead of more grow-out cages, and measure success as the share of farmed fish that is processed, cold-stored and sold as a durable local product. Avoid subsidising more production into a chain that cannot store, process or move it.

Where this connects. Pillar 1 sets out the biology behind the feed and seed openings. Pillar 5 examines the same farm margin in its cost-and-returns model, where feed at three-quarters of cost is the leak to the input end seen from the farm. Pillar 7 covers the financing, policy and investment that aim to bring processing, cold chain and anchor investments into the missing middle.
