A Ghanaian canoe owner can price the fuel going into the boat to the pesewa and cannot price most of the fish coming out. Catch and first-sale price swing by season and species, so the revenue side is where a canoe budget is least certain.
The most detailed breakdown of a Ghanaian canoe trip’s cost by gear comes from a 2016 survey of 70 motorised owners across the four coastal regions;1later studies confirm fuel as the largest cost, at 53 to 56 per cent of fishers’ costs in 2021.21The 2016 survey’s cedi amounts cannot carry forward, but its cost shares can. Across all gears, halving every non-fuel cost would raise the owner’s net by about 14 per cent and cutting fuel by a fifth by about 11 per cent; for a purse seine, where fuel is 73 per cent of the operating cost, the two are close, at about 9 and 10 per cent.
| Gear | Fuel | Maintenance | Supplies | Operating cost a trip, 2016 cedis | Owner net a trip, 2016 cedis |
|---|---|---|---|---|---|
| Purse seine (poli, watsa) | 73.4% | 14.4% | 12.2% | GH¢448.50 | GH¢339.50 |
| Ali net | 70.9% | 13.6% | 15.5% | GH¢499.92 | GH¢63.55 |
| Drifting net | 55.2% | 15.6% | 29.2% | GH¢1,866.67 | GH¢1,751.88 |
| Hook and line | 42.3% | 11.5% | 46.2% | GH¢938.67 | GH¢426.55 |
| Beach seine | 38.5% | 1.0% | 60.5% | GH¢39.25 | GH¢83.17 |
| Set net | 80.0% | 7.5% | 12.5% | GH¢177.50 | GH¢124.11 |
| All gears | 65.5% | 12.7% | 21.8% | GH¢613.17 | GH¢380.47 |
Source: Tobey et al., Figures 20 and 23 and Table 7, from 70 motorised canoe owner interviews. Cedi amounts are nominal 2016 and not comparable with any later year. Owner net is profit accruing to the boat owner after labour and operational costs.1
Labour takes 50 per cent of what is left after operating costs: a 2016 purse seine trip grossed about GH¢1,128, of which GH¢329 was fuel (29 per cent of catch value), and the owner kept 30 per cent. The crew share moves with the catch, not as a wage; the system is Pillar 4’s.
That GH¢329 bought between 26 and 44 gallons, depending on whether it is derived from fuel a trip or from the beach price. Supply was the problem: 62 per cent of owners got premix less than half the time they needed it, and fishers in some remote areas reported paying middlemen up to GH¢13.00 a gallon against the approved GH¢7.10 to GH¢7.80.1
What this means. Fuel is the largest running cost of a Ghanaian canoe trip, so most operating savings come from buying fuel more cheaply or burning less. Gear choice is a cost structure choice before a fishing choice: a set net operator carries four fifths of the cost base in a commodity whose price the state sets; a hook and line operator carries under half.
The fuel line has an official 2026 price. From May to August 2026 the administered rate was GH¢176.40 for the yellow gallon used to measure premix at the landing beach, capped at GH¢180 where making exact change was impractical.3
The National Petroleum Authority prices premix by the litre: GH¢5.3557 a litre in January 2025, cut by about 16 per cent from 1 January 2026.4 From 1 September 2026 the approved beach price is GH¢5.51 a litre, GH¢24.80 for a gallon of 4.5 litres and GH¢174 for the yellow gallon, the price of about seven gallons.5 At 35 gallons a trip, the middle of the 26 to 44 gallons a 2016 purse seine trip used, the fuel bill at the September 2026 price is about GH¢868, about 13.5 per cent of the value of a 330 kg catch.6
Two costs cannot yet be budgeted from the statute. The canoe licence fee is not yet known: the draft Fisheries and Aquaculture Regulations under Act 1146, which cover licensing and registration, went to stakeholder review in July 2026.7 A marine artisanal fishing vessel faces 250 to 500 penalty units under section 161(c), which Pillar 3 prices at roughly GH¢3,000 to GH¢6,000.7 The fine is small; forfeiture is the larger risk, since the same section allows catch and gear to be taken, and a net and a 40 hp outboard cost about GH¢125,000 new in 2026 (Table 13).
Ghana’s newest measured fish price covers three small pelagic species on two gear types around the 2023 closed season. On ali, poli and watsa (purse seine) gear, round sardinella landed at a mean GH¢16.91 a kilogram before the 2023 closed season and GH¢16.66 after it, and flat sardinella at GH¢16.66 rising to GH¢17.06; on set nets, flat sardinella fetched GH¢24.20 and GH¢22.82.8 Anchovy on the same gear carried a mean landing price of GH¢9.59 a kilogram before the 2023 closed season and GH¢11.27 after it, on ali, poli and watsa gear.8 Brought to 2026 by consumer price inflation of about 41 per cent since August 2023, the catch-weighted 2023 purse seine price of GH¢13.81 a kilogram becomes about GH¢19.50, the price the 2026 cost model uses.9
Dividing the Fisheries Commission’s 2023 artisanal landed value, GH¢4.61 billion, by its tonnage, 230,892.55 tonnes, gives an average of about GH¢20 a kilogram across all species in 2023.10 Spread across the 12,175 operational canoes that the 2022 frame survey counted, 2023 landings average about 19 tonnes and GH¢378,500 a canoe a year.10

A price series as a product. A credible monthly landing beach price series, by species and site, has several buyers and few sellers: processors to buy against, lenders to lend against, and a ministry that needs it to read its indicators, while aggregators already charge for a substitute that fails one methodological question. Two seasons of prices from three landing sites, by species and grade, would give processors and lenders a price record they can use.
Catch a trip, trips a year and the first sale price move the owner’s annual net most. Across the 2023 purse seine range of 182 to 485 kg a trip the net runs from about GH¢28,700 to GH¢200,000 on the 2026 base of GH¢112,359; between 40 and 100 trips a year it runs from about GH¢66,700 to GH¢218,900; and between anchovy’s and flat sardinella’s 2023 prices brought to 2026, GH¢13.50 to GH¢24.10 a kilogram, from about GH¢54,900 to GH¢156,400. The owner share comes fourth. Fuel matters less than it did in 2016: premix was 29 per cent of a purse seine trip’s catch value then and is about 13.5 per cent at 2026 prices, and removing the whole subsidy would cut the owner’s net by about a fifth, to about GH¢87,200.
Fixed costs move the answer least, so the financing question here is working capital.
What the sensitivity analysis means for an operator. The variables that decide whether a canoe pays are the catch it lands, the trips it makes and the price it gets, with the owner share and fuel after them. The Fisheries Commission publishes a national catch a trip, 454 kg in 2023 against 626 kg in 2022;10 the most recent published fuel use a trip by gear is from 2016.1 An operator who records both on their own boats for one season will know their break-even far better than any published average.
Costs and prices move with the wider economy, in both directions. Ghana’s inflation fell from 23.5 per cent in January 2025 to 3.2 per cent in March 2026, the lowest since the 2021 rebase, and stood at 5.0 per cent in August 2026, with food inflation at 3.0 per cent.14159 The Bank of Ghana held its policy rate at 14 per cent in July and September 2026, and the average bank lending rate was about 15.9 per cent in August.161718 The cedi, which strengthened through 2025, lost about 9.5 per cent against the US dollar in 2026 to mid-July.16
Several of a canoe’s costs follow the dollar. Premix is refined from imported crude and priced by the National Petroleum Authority, which reviews the subsidised price every quarter: it was cut by about 16 per cent from January 2026 and set at GH¢5.51 a litre from September.45 Outboard motors, nets and spare parts are imported, and a new 40 hp outboard listed at GH¢35,000 to 45,000 on Jiji in 2026, about three times its 2016 price.1311 Imported frozen fish, the cheapest competing protein, arrived at about US$0.66 a kilogram in 2025,19 so a stronger cedi makes imports cheaper and pulls local prices down, and a weaker one does the opposite.
These moves can reverse. Re-cost fuel, gear and fish before every season, keep a cash buffer against both a fall in the landing price and a rise in costs, and prefer supply and offtake agreements that fix the price or tie it to costs.
Move the inputs yourself. Set the catch a trip, the first-sale price, the trips a year, the owner’s share and the premix price to your own landing site’s figures, then swing them one at a time. Push the catch, the trips or the price and watch the owner’s net move fast; push the premix price to the subsidy removed and watch it fall by about a fifth. The model is the 2026 purse seine canoe of Table 13.
Slide the five inputs that decide a motorised purse seine canoe owner’s year: the catch a trip, the first-sale price a kilogram, the trips a year, the owner’s share of the net catch and the premix price a gallon. Watch the first-sale revenue, the fuel bill, the break-even and the owner’s annual net move. Type your own landing site’s figures into the boxes to test any season.
Base case (2026 prices): a motorised purse seine canoe landing 330 kg a trip, the mean of the 2023 purse seine observations of 182 to 485 kg, over 58 trips a year, which lands the 2023 average of about 19 tonnes a canoe; a first-sale price of GH¢19.50 a kilogram, the catch-weighted 2023 purse seine price of GH¢13.81 brought to 2026 by consumer price inflation of about 41 per cent; premix at 35 gallons a trip and the approved beach price of GH¢24.80 a gallon from 1 September 2026, GH¢868 a trip; maintenance GH¢268 and supplies GH¢228 a trip, the 2016 cost shares brought to 2026; the net catch value shared half to the owner and half to a crew of 20; and fixed costs of GH¢34,700 a year, for a net of GH¢85,000 over five years, a canoe of GH¢97,000 over ten and a 40 hp outboard of GH¢40,000 over five. That gives an owner annual net of GH¢112,359, GH¢7,353 a year for each crew member, and a break-even of 131 kg a trip or GH¢7.76 a kilogram.895111121013 Indicative planning values. Figures are as reported between July and September 2026 and may have changed since.
The smaller-capital business is on land: a fish-smoking enterprise on an improved oven nets about GH¢42,900 a year over 100 cycles at 2026 prices, buying 60 kg of fresh fish a cycle at GH¢19.50 a kilogram and selling 30 kg smoked at about GH¢56. It turns on the smoking yield and the smoked price: below a yield of about 37 per cent, or a smoked price of about GH¢41 a kilogram, a cycle does not cover its costs. The interactive model here is the canoe.
The same model, re-run as the sensitivity tornado. Each bar is how far the owner’s annual net moves across that one input’s range, holding the others where you left them. The catch, the trips and the price lead.
How many kilograms the canoe lands, across the measured 2023 purse seine range of 182 to 485 kg a trip. The widest lever at the base case, and the first number to record on your own boats.
From 40 to 100 trips a year. Weather, the lean season and days ashore decide it; 58 trips of 330 kg land the 2023 average of about 19 tonnes a canoe.
The landing price, from anchovy's 2023 purse seine price to flat sardinella's, both brought to 2026: GH¢13.50 to GH¢24.10 a kilogram.
The split between owner and crew after running costs, from 40 to 60 per cent. Ghanaian surveys record half to the owner and half to the crew.
From a 10 per cent cut, GH¢22.32 a gallon, to GH¢49.60 with the subsidy removed. Removing the whole subsidy cuts the owner's net by about a fifth at the base case.
From 26 to 44 gallons a trip, the range a 2016 purse seine trip used. A purse seiner burns about four gallons an hour, so each hour saved is about four gallons.
Each bar holds the other inputs where you left them and moves one across its range: catch 182 to 485 kg a trip (the measured 2023 purse seine range), trips 40 to 100 a year, first-sale price GH¢13.50 to GH¢24.10 a kilogram (anchovy to flat sardinella, 2023 prices brought to 2026), owner share 40 to 60 per cent, premix GH¢22.32 to GH¢49.60 a gallon (a 10 per cent cut to the subsidy removed) and premix 26 to 44 gallons a trip. At the base case the ranks and values match the Sensitivity sheet of the 2026 cost and returns model and Figure 13.
Sensitivity shows which number matters; the levers below show what an operator can change, since the widest bar depends on a shared stock. They are ordered by speed of return: the first two cost nothing, and everything below them needs capital or collective action.
| Lever | What it changes | Indicative saving | What it costs to put in | Order |
|---|---|---|---|---|
| Buy premix at the approved beach price | Removes the middleman premium on the largest cost line | In 2016 middlemen charged up to GH¢13.00 a gallon against about GH¢7.50 at the beach; at the September 2026 price of GH¢24.80 a gallon a premium of that size would cost the owner about GH¢18,400 a year | No cash: presence when supply lands and a landing beach relationship | 1 |
| Cut engine hours while keeping trips | A purse seiner burns four gallons an hour, so an hour saved is four gallons | About GH¢99 a trip for each hour removed, about GH¢2,900 a year to the owner | An echo sounder, as the government gave 13 fishing communities in 2012,6 or shared landing information between canoes | 2 |
| Match the gear to the cost structure | Fuel is 80 per cent of a set net's operating cost and 38.5 per cent of a beach seine's | Changes the exposure to the fuel price: a beach seine made GH¢58 of owner net per gallon of fuel in 2016, an ali net under GH¢5 | Gear capital and crew retraining. The gear systems are in Pillar 4 | 3 |
| Buy gear and nets as a group | A worked example in a 2015 value chain study put nets level with fuel in a fisher's costs | Volume terms on the joint largest input. Not quantified in any Ghanaian source | The associations already exist; building trust among members is the constraint | 4 |
| Replace the illegal small mesh net | Larger fish command more than twice the price of juveniles | A 52 per cent increase in profit per boat, worth GH¢189 million a year nationally in 2020 cedis, a benefit-cost ratio of about five at an 8 per cent discount rate | GH¢267 million once nationally in 2020 cedis, about 40 per cent borne by fishers, and only works if everyone does it. Enforcement is Pillar 3 | 5 |
| Ice at the landing, before the market | Moves fish out of the downgraded grade before value is lost | Ice is a small line in a fisher's costs, against a post-harvest loss estimated at 22.5 per cent of total fish production in 2023 | Ice plants at new landing sites, such as the 60-tonne ice plant at the Jamestown fishing harbour20 | 6 |
| Replace the fishmonger's advance with a priced loan | Converts a hidden price concession into a visible interest cost | Unquantified, because the concession is never written down | Rural bank credit at 3 per cent a month in about 2018 to 2019, after first saving 20 per cent of the loan as cash collateral | 7 |

In a Ghana Standards Authority test, fish smoked on the Ahotor oven carried 10.93 micrograms of polycyclic aromatic hydrocarbons a kilogram against 84 for the Chorkor,23and a 2024 trial found improved kilns used a fraction of the Chorkor’s fuel.2423 Processors told the project that Ahotor fish prices did not compensate for the investment and that the oven shrinks the fish, which lowers its value when fish is sold by size; poor early construction, material costs, working capital and low catches also held adoption back.23 In 2026 fewer than 1 per cent of processors had upgraded to improved ovens, mainly because of cost.2523 Only 76 of 520 ovens were built without a subsidy of 88 per cent or more.22
At 2026 prices a smoking cycle buys 60 kg of fresh fish at about GH¢19.50 a kilogram and, at a yield of half, sells 30 kg of smoked fish at about GH¢56 a kilogram, the 2019 Elmina smokers’ price brought to 2026.26That returns about GH¢443 on a cycle cost of GH¢1,237, 36 per cent on cost, or about GH¢42,900 a year over 100 cycles. The result turns on the yield and the smoked price: below a yield of about 37 per cent, or a smoked price of about GH¢41 a kilogram, the cycle loses money. An improved oven saves about GH¢630 of firewood a year on these figures, so its extra cost over a Chorkor oven takes about nine years to repay from firewood alone. A 2021 survey measured processors’ profit at GH¢2,213 a month in the peak season and a 45 per cent margin, with fish the largest cost.2
Why a better technology has not spread.The Ahotor record is a warning for any efficiency technology in this chain. The oven is cheaper to run, safer and better for the consumer, yet processors reported that its prices did not compensate for the investment, since it made the fish smaller and the buyer pays by size, and adoption has stayed low. Any equipment business here must sell the buyer first and the processor second, and must solve the processor’s cost and working capital at the same time.
One of the largest commercial numbers in Ghanaian marine fisheries is a loss. The national post-harvest loss assessment puts it at 22.5 per cent of total fish production, worth GH¢2.6 billion, with the marine sector carrying 95 per cent of the loss.10Marine’s share was about GH¢2.47 billion in 2023, close to the size of Ghana’s entire fish export account, which was about US$201 million in 2023 and US$234 million in 2025.1927 One percentage point of the marine loss rate recovered was worth about GH¢115 million in 2023 cedis.
A separate study of the same chain reports less than 5 per cent post-harvest loss, on the reasoning that all landed catch is used, directly by humans and indirectly through the poultry and aquaculture sectors.21 The two figures measure different things: the 2023 assessment covers physical and quality loss across the whole fish chain, including tuna, tilapia and catfish, while the 2015 study counted only fish discarded from the small pelagic chain. A 2021 survey of the same chain found up to 5 per cent of commercial catch lost to spoilage,2 and an earlier project estimate put physical loss from lack of cold storage at about 20 per cent.22
Action points. Size a loss-recovery business on the loss it targets, and state the basis: spoilage of small pelagics at the landing runs at up to 5 per cent, while the 2023 national assessment puts total physical and quality loss at 22.5 per cent of production. Much of the recoverable value is in quality, so a grading standard and an offtake contract should come before a freezer.
In 2018 to 2019, three Central Region rural banks offered fish processors credit at 3 per cent interest a month, after first saving 20 per cent of the loan as cash collateral, repayable over six to twelve months.22 That is about 36 per cent over a twelve-month term, before the cost of accumulating the collateral. A state microfinance agency could offer GH¢1,000 against an average request of GH¢4,000, in cedis of about 2018 to 2019.
The most common credit rarely appears as a cost. The fishmonger who prefinances the trip buys the catch and sets its price, so the loan is repaid in a price concession, carries no stated rate and cannot be refinanced. Price formation is Pillar 6’s, the instruments Pillar 8’s.
The unwritten interest rate.Because the fishmonger’s advance is repaid through the beach price rather than as interest, it rarely appears in a business plan. Any lender here competes with a relationship that also guarantees the sale, and must replace both halves. The first step to pricing against that hidden rate is measuring the difference between the price a prefinanced canoe receives and a free one does, on the same beach and morning. No published source measures this price gap.
The canoe budget turns on the catch a trip and the landing price, and both swing by season and species. A run of poor trips can turn a paying canoe into a loss within weeks.
At 2026 prices a purse seine canoe breaks even at about 131 kg a trip or GH¢7.76 a kilogram. The national catch fell from 626 kg to 454 kg a trip between 2022 and 2023,10 and 2021 crate prices ran from GH¢76 in the peak season to GH¢237 in the lean season.2
Canoe owners, crews paid by share, and anyone lending against a canoe.
Budget on lean-season catches, keep cash for the lean months, and record catch and price every trip. A trip-by-trip record is also a product: processors and lenders need the same numbers.
Premix is the largest running cost of a canoe trip and is administered by the state. Supply stalls when subsidy payments fall behind, and the price is reviewed every quarter.
Unpaid claims to fuel distributors reached GH¢115.9 million before they were cleared in January 2026.28 The price moved from GH¢176.40 a yellow gallon in May 2026 to GH¢174 in September.35 Removing the whole subsidy would cut a purse seine owner’s net by about a fifth.
Canoe owners and crews, and beaches far from an automated outlet.
Buy only at the approved price, keep a fuel reserve for a supply gap, and follow the National Petroleum Authority reviews. Metered outlets and fuel logistics for remote beaches are an opening as the 300-outlet rollout continues.
A smoker's profit depends on how much weight the fish loses and on the smoked price. Both vary by species, oven and season.
At 2026 prices a cycle loses money below a yield of about 37 per cent or a smoked price of about GH¢41 a kilogram. Fewer than 1 per cent of processors had upgraded to improved ovens by 2026, mainly because of cost.25
Women processors, and suppliers selling them ovens on credit.
Weigh fish in and out of every batch, and hold smoked stock for the lean season, when smoked herring sold about 41 per cent higher at Elmina in 2019.26 Pair any oven sale with a buyer who pays for low-smoke fish.
Fuel was 73 per cent of what it cost to run a purse seine canoe in 2016 and 65 per cent across all gears, and fuel remained over half of fishers' costs in 2021.
From 1 September 2026 premix costs GH¢24.80 a gallon and GH¢174 a yellow gallon; fish prices are measured less often, with the latest by species and gear from the 2023 closed season.
The inputs that decide whether a canoe pays are the catch a trip, the number of trips and the landing price. At 2026 prices the owner of a purse seine canoe nets about GH¢112,000 a year on 58 trips and breaks even at about 131 kg a trip.
Post-harvest loss of 22.5 per cent, worth GH¢2.6 billion with the marine sector carrying 95 per cent of it, is close to the size of the fish export account. Much of the recoverable value lies in quality, so a grading standard and an offtake contract should come before a freezer.
The Ahotor oven cuts fuel and carcinogens, but processors reported that its fish did not earn a higher price and that the oven shrinks fish sold by size; only 76 of 520 were built without a subsidy of 88 per cent or more by 2019, and fewer than 1 per cent of processors had upgraded by 2026.
Where this connects. The stock ceiling capping the catch line is Pillar 1; the price evidence and gaps around the 2023 measurement are Pillar 2; enforcement and the penalty regime are Pillar 3; the crew share system, gear choices and premix distribution are Pillar 4; the pricing convention that leaves a better oven unrewarded and the margins beyond the landing are Pillar 6; and the finance instruments and statutory fee regime that would make the licence line budgetable are Pillar 8.
