Cost and Returns

A canoe owner can price the fuel to the pesewa, 65.5 per cent of operating cost at GH¢176.40 a premix gallon, and cannot price most of the fish coming out. The two inputs that decide whether a canoe pays are the two nobody measures.
Cost and returns · Pillar 05

A Ghanaian canoe owner can price the fuel going into the boat to the pesewa and cannot price most of the fish coming out. Almost every fisheries business plan written in Ghana this year is precise about costs and guessing about revenue: the two inputs deciding whether a canoe pays are the two nobody measures.

🐟 What a fishing trip costs, and the one measurement Ghana has 🐟

Only one survey has ever measured a Ghanaian canoe trip’s cost: 70 motorised owners across the four coastal regions1. Its 2016 cedi amounts cannot carry forward, but the cost shares can. Halving every non-fuel cost improves the operating line by about a seventh; cutting fuel by a fifth improves it slightly more.

Where the money goes on a canoe trip, by gear, and how much of it is fuel
Figure 11 Where the money goes on a canoe trip, by gear, and how much of it is fuel

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.

How much premix that GH¢329 bought is unsettled, at 26 to 44 gallons depending on the derivation, a purchase-price problem: 62 per cent of owners got premix less than half the time they needed it and bought from middlemen at up to GH¢13.00 a gallon.

What this means. Any cost model of Ghanaian canoe fishing is a fuel model with other lines attached: every operating improvement worth pursuing either buys fuel more cheaply or burns 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.

🐟 Premix: the only current price in this commodity, and the unit nobody has defined 🐟

The fuel line is the one place here with an official 2026 figure: the administered rate is GH¢176.40 for the yellow gallon used to measure premix at the landing beach, capped at GH¢180 where making exact change is impractical2. Against a revenue side whose newest measurement is three years old, the budget is precise on the way in and speculative on the way out.

No source states the litre content of the 2026 yellow gallon, so it cannot convert to a price a litre or set against the GH¢7.10 to GH¢7.80 a gallon owners paid in 2016. The cost model holds its fuel line at 40 litres a trip and GH¢4.50 a litre, GH¢180. As cash that sits close to GH¢176.40 for one yellow gallon; as quantities they cannot compare, since 40 litres is 8.9 of the only defined gallon on record3.

Two costs cannot yet be budgeted from the statute. No licence fee applies to a canoe, since the fee is unstatable while the Act’s licensing Regulations sit in draft4; and a canoe, being 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, or 3 to 7 per cent of the modelled canoe and motor. The fine is survivable; the forfeiture is not, since the same section allows catch and gear to be taken, against a gear and net line of GH¢15,000 a year.

🐟 The revenue side, and the honest statement of what cannot be computed 🐟

Ghana’s newest measured fish price covers three small pelagic species on two gear types around the 2023 closed season. Round sardinella landed at a mean landing price of GH¢16.91 a kilogram before the 2023 closed season and GH¢16.66 after it for round sardinella taken on ali, poli and watsa gear, with flat sardinella at GH¢16.66 rising to GH¢17.065. 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 gear6. The model’s GH¢20 a kilogram sits above all six observations, so its price is uncorroborated. At round sardinella’s GH¢16.91 the owner’s annual net falls from GH¢68,670 to about GH¢50,300, down 27 per cent; at anchovy’s GH¢11.27 to about GH¢16,800, in nominal 2023 cedis.

Dividing the Fisheries Commission’s own 2023 artisanal landed value by its tonnage, 230,892.55 tonnes, worth GH¢4.61 billion7, gives an implied GH¢19.96 a kilogram, the same number twice, so it cannot corroborate the model’s GH¢20. Spread across the 9,122 motorised canoes the 2016 frame survey counted, that value puts about GH¢505,000 on each a year against the model’s GH¢360,000, so the model runs about 29 per cent below an upper bound.

Commercial aggregators sell a 2026 Ghana wholesale price naming no species, no point in the chain and no method; a plan quoting a current Ghana fish price almost certainly took it from one of those services.

The product this pillar keeps pointing at. A credible monthly landing beach price series, by species and site, has several buyers and no seller: processors to buy against, lenders to underwrite 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 from three landing sites would produce the only defensible fish price in the country.

🐟 Sensitivity: which input decides the answer 🐟

What moves the canoe owner's annual net, and by how much
Figure 13 What moves the canoe owner’s annual net, and by how much

Catch a trip and premix quantity dominate, each moving the owner’s annual net by roughly GH¢130,000 to GH¢135,000 on a base case of GH¢68,670, both unmeasured in Ghana. Premix runs from the model’s GH¢180 cash line to twenty yellow gallons at the administered rate, so break-even sits at roughly eleven gallons a trip. First sale price is third whether it runs across the workbook’s GH¢15 to GH¢30 band or the measured 2023 range of GH¢10 to GH¢24.20, narrowing the bar to GH¢84,348 without moving its rank. Owner share runs from the model’s 0.33 to the 0.50 the one measured Ghanaian study implies, at which the base case becomes GH¢123,750.

A canoe business cannot be rescued by buying a cheaper boat: fixed costs move the answer least, so the financing question here is a working-capital question.

Why the sensitivity analysis is also a fieldwork plan. The two variables that decide whether a canoe pays are the catch it lands and the fuel it burns getting there, and Ghana measures neither: no national catch-a-trip series exists, and gallons a trip go unmeasured since 2016. An operator who spends one season measuring both on their own boats knows more about their economics than the national evidence base does.

🐟 Model it yourself 🐟

Numbers on a page are one thing. Move the levers yourself. Set the catch a trip, the first-sale price, the owner’s share and the premix fuel bill to your own landing site’s figures, then swing them one at a time. Push the catch or the fuel slider and watch the owner’s net move fast, then buy a cheaper boat and watch it barely stir. That is the argument of this pillar in one gesture: the two numbers that decide whether a canoe pays are the catch it lands and the fuel it burns, and both go unmeasured in Ghana. Every figure is indicative, so overwrite it with your own.

Tool 1

Does the canoe pay?

Slide the four levers that decide a motorised purse-seine canoe owner’s year: the catch a trip, the first-sale price a kilogram, the owner’s share of the net catch, and the premix fuel bill a trip. Watch the first-sale revenue, the costs the owner carries, and the owner’s annual net move. Every figure is indicative, so overwrite each one with your own landing-site numbers.

GH¢360,000
First-sale revenue a year, 150 kg a trip at GH¢20/kg across 120 trips

Owner’s 33% share of the net catch, before gear, motor and depreciation
+GH¢68,670
Owner annual net · crew take home GH¢18,090 each, of 12
At these numbers the owner clears GH¢68,670 for the year, and look at what carried it there. The catch a trip and the premix bill move the net fast; the price moves it less; and a cheaper boat would barely help. The trouble is that the two levers doing the most work, the 150 kg the catch slider shows and the gallons the fuel slider burns, are the two numbers Ghana does not measure. Break-even here sits at about 63 kg a trip at this price, or GH¢8.44 a kilogram at this catch, so a plan built on a spreadsheet fuel line of 40 litres a trip is precise about the wrong things.

Base case: the Pillar 5 Table 13 frame, one motorised purse-seine canoe a year. Catch 150 kg a trip over 120 trips at GH¢20 a kilogram gives a first-sale value of GH¢360,000; premix at 40 litres and GH¢4.50 a litre is GH¢180 a trip and other running cost GH¢120, so the net catch value is GH¢324,000; the owner’s 33 per cent share is GH¢106,920, and after GH¢38,250 of gear, motor and depreciation the owner annual net is GH¢68,670. Parameters from the Marine Fisheries Cost and Returns Model, grounded in Tobey et al.1, Tetra Tech for USAID5 and the Fisheries Commission7. Every figure is indicative: no published Ghanaian canoe budget exists (gap PD-9), so field-verify by species and gear before you rely on it.

The low-capital alternative is on land, not water: a fish-smoking micro-enterprise on an improved Ahotor oven costs about GH¢6,000 and returns about GH¢39,800 a year, against the canoe’s GH¢68,670 on GH¢90,000 of capital. It is the better business per cedi of capital, though it still loses money on the sale because the oven shrinks a fish the buyer pays for by size. The interactive model here is the canoe.

Tool 2

What swings the net most

The same model, re-run as the sensitivity tornado. Each bar is how far the owner’s annual net moves across that one driver’s plausible range, holding the others where you left them. Two drivers lead and tie, and both are numbers Ghana does not measure.

1. Catch a trip, in kilograms±GH¢134,640

How many kilograms the trip actually lands, from 80 kg in the lean season to 250 kg in a glut. It is a joint-widest lever and one nobody measures in Ghana: no national catch-a-trip series exists. This is the first number an operator should spend a season recording on their own boats.

2. Premix fuel, the gallons a trip±GH¢132,581

Fuel is the largest cost line, and its quantity is the other unmeasured number. The bar runs from the model's GH¢180 cash line to twenty yellow gallons at the administered rate, and break-even arrives at roughly eleven gallons a trip. It ties with the catch for the widest swing.

3. First-sale price a kilogram±GH¢84,348

The beach price, third in rank whether it runs across the workbook's GH¢15 to GH¢30 band or the measured 2023 range of GH¢10 to GH¢24.20. Ghana's newest measured fish price is three years old and covers three small pelagic species, so this is a guess dressed as a figure.

4. Owner share of the net catch±GH¢55,080

The split between owner and crew, a modelling choice with no Ghanaian source. It runs from the model's 0.33 to the 0.50 the one measured study (Tobey, 2016) implies, at which the base case becomes about GH¢123,750. Fourth in rank, below the price.

5. Fixed costs: gear, motor and depreciation±GH¢25,500

Net and gear replacement, motor upkeep and the depreciation of the canoe and motor. It moves the net least, so a canoe business cannot be rescued by buying a cheaper boat: the financing question here is a working-capital question, not a capital-cost one.

±GH¢134,640
What the catch a trip does, from 80 to 250 kg, one of the two widest levers
±GH¢25,500
What the whole fixed-cost line does, gear, motor and depreciation, the smallest swing
The catch a trip and the premix quantity dominate, each moving the owner’s annual net by roughly GH¢130,000 to GH¢135,000 on a base of GH¢68,670, and both are unmeasured in Ghana. The first-sale price is third, narrowing to about GH¢84,348 across the measured 2023 range without changing rank. The owner share is fourth, worth about GH¢55,000 as it runs from the model’s 0.33 to Tobey’s measured 0.50. The fixed costs move the net least. This ranking matches the Sensitivity sheet of the Marine Fisheries Cost and Returns Model and the Pillar 5 tornado, and it is also a fieldwork plan: the two variables that decide whether a canoe pays are the two an operator can measure in one season and the national evidence base cannot.

Each bar holds three levers where you left them and moves the fourth across its range: catch a trip 80 to 250 kg, premix a trip GH¢180 to twenty yellow gallons at GH¢176.40, first-sale price GH¢10 to GH¢24.20 (the measured 2023 range), owner share 0.33 to 0.50, and fixed costs across a plausible gear, motor and depreciation band. Ranks match the Sensitivity sheet and the Pillar 5 tornado. Indicative figures, to validate against your own trip records.

🐟 Cost cutting: what can be taken out, and in what order 🐟

Sensitivity says which number matters, not what an operator can do, since the widest bar is a shared stock nobody controls. The levers below are ordered by speed of return: the first two cost nothing, and everything below them needs capital or collective action.

The processing side, where the best lever loses money

The Ahotor oven burns less wood and cuts polycyclic aromatic hydrocarbons in smoked fish from 84 to 10.93 micrograms a kilogram8; firewood was GH¢400 of a GH¢1,610 processor cost line in 20159. It still does not pay: processors reported that Ahotor prices do not compensate for the investment and that the oven shrinks the fish, so a product sold by size loses on the sale10. Only 76 of 520 ovens were built without a subsidy of 88 per cent or more11.

The oven’s enterprise is still the better business per cedi of capital. A smoking cycle buys 50 kg fresh fish, produces 25 kg smoked and returns GH¢410 on a cycle cost of GH¢1,090, a 38 per cent margin, so the oven returns about GH¢39,800 a year on capital of GH¢6,000 while the canoe returns GH¢68,670 on GH¢90,000. The one 2015 measurement of a processor’s accounts shows 61 per cent on cost, but its cost line holds no fish purchase while 92 per cent of the model’s cycle cost is fish, so the two cannot be ranked.

Why a better technology lost money. Read the Ahotor record before assuming any efficiency technology sells itself in this chain. The oven is cheaper to run, safer and better for the consumer, and still lost money for the operator, because it made the fish smaller and the buyer pays by size. Any equipment business here must sell the buyer first, the processor second; the real constraint is a pricing convention, not the technology.

The largest number in the sector
A loss, not a price: the largest commercial figure in Ghanaian marine fisheries.
22.5%
of total fish production lost, worth GH¢2.6 billion
95%
of that loss carried by the marine sector

The largest commercial number 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 loss12. Marine’s share is about GH¢2.47 billion, roughly US$220 million at the June 2026 rate of about GH¢11.20 to one US dollar13, larger than the entire Ghanaian fish export account. One percentage point of the marine loss rate recovered is worth about GH¢115 million a year on this playbook’s arithmetic.

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 sectors14. That counts quantity: nothing landed is wasted, while the 22.5 per cent counts value, so a downgraded fish sold cheap is fully used on the first measure while most of its worth is gone on the second.

Action points. Size a loss-recovery business on the value assessment, not the physical reading, and say which you used. A proposal recovering fish currently thrown away is building against a five per cent problem; one lifting fish out of the downgraded grade is building against a 22.5 per cent one, and the intervention is a grading standard and an offtake contract before a freezer.

What capital costs here, and the loan that never appears in a budget

Formal credit for this chain has been documented on stated terms exactly once: 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 months15. 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 credit that functions never 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 interest rate nobody writes down.Because the fishmonger’s advance is repaid in the beach price, not interest, it is invisible to every business plan in this sector, including this playbook’s own cost model. 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. Nobody has measured it.

🐟 Key takeaways 🐟
01

Fuel is 73 per cent of what it costs to run a purse seine canoe, 65 per cent across all gears, so every cost model here is a fuel model with other lines attached.

02

Premix has a hard 2026 administered price of GH¢176.40 for a yellow gallon whose volume nobody publishes; the fish has one measured price, for three small pelagic species in 2023. Ghana can price the fuel into a canoe exactly and cannot price most of the catch coming out.

03

The two inputs that decide whether a canoe pays are the catch a trip and the gallons a trip, and Ghana measures neither. Break-even arrives at about eleven yellow gallons a trip on the cost model's other assumptions.

04

Post-harvest loss of 22.5 per cent, worth GH¢2.6 billion with the marine sector carrying 95 per cent of it, is larger than the fish export account. Reading two sources that measure different things, this playbook finds the loss is in the grade, not the bin, so the fix is a grading standard and a contract before a freezer.

05

The Ahotor oven cuts fuel and carcinogens and still loses processors money, because fish is sold by size and the oven shrinks it. Only 76 of 520 were built without a subsidy of 88 per cent or more.

Written for each reader

🐟 Practitioner intelligence 🐟

Hover any card to pause and lift it.

For students

The first move: if you are entering on the economics side, sell the numbers before you buy the boat. Spend one season at a single landing site recording two things on six canoes: gallons of premix in, and what the owner was paid for the landing. Unmeasured in Ghana for a decade, these two numbers alone buy a dataset processors, lenders and the ministry all lack. The mistake first-timers make is buying a canoe share because the annual net looks respectable on a spreadsheet whose fuel line is 40 litres a trip in a market that buys premix by an undefined gallon.

For entrepreneurs

First move: fix the fuel line before modelling anything else. Ask three landing sites what a gallon costs today and how many gallons a trip takes: the published model's 40 litres a trip cannot convert into the gallon anyone buys. Secure the offtake, specify the product, then buy equipment, in that order: the Ahotor record shows what happens when equipment comes first. The costliest trap is treating the fishmonger's advance as free money: a plan showing no interest cost has moved that cost into a revenue line the lender will not see.

For investors

The proposition here: cost certainty going in and grade recovery coming out, since volume has a resource ceiling from Pillar 1 and price has no observable market. Require any canoe exposure to produce gallons a trip and the beach price a gallon from its own records; treat inability to produce them as disqualifying. Require every revenue assumption to name species, gear and year, since the only measured prices are 2023 and cover three small pelagic species. Require the crew share to be stated, since the model's 33 per cent owner share is an assumption with no Ghanaian source and the only measured figure on that basis is 50 per cent, worth about GH¢55,000 a year on a base of GH¢68,670. Release the cheque against a measured season of trip data and a signed offtake, and underwrite the cost line, not the revenue line.

For ecosystem actors

The lever: measurement of two numbers, and cheap. Adding gallons a trip and catch a trip to the annual canoe frame survey, and publishing a monthly landing beach price series by species, would together cost a fraction of one harbour rehabilitation and move the share of underwritable fisheries business plans, currently close to none. Attach the litre content of the yellow premix gallon to the same publication: the state administers that price and nobody outside it can convert it. The failure to avoid is subsidising equipment ahead of the market that would pay for it, since only 76 of 520 ovens in the programme's adoption ratio were built without an 88 per cent subsidy.

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 makes a better oven lose money 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.
