What if a US$2 million investment in fish farming paid back almost three dollars for every dollar spent — every single year? That is what Zimbabwe just reported. At the FISH4ACP Zimbabwe Legacy Event in Harare in November 2026, the Food and Agriculture Organization of the United Nations (FAO) revealed the final results of a five-year programme to rebuild the country’s tilapia value chain: about US$2 million invested, an estimated US$3.6 million in annual economic benefits, and 4,206 fish farmers directly reached.
The headline number is striking, but the story behind it is more useful than the headline. Zimbabwe did not get there by handing out ponds. It fixed the three things that were strangling its tilapia farmers — expensive feed, scarce fingerlings and no organisation — and the fish, and the money, followed. This post breaks down the numbers, the maggot-feed breakthrough that made it possible, and what Indian fish farmers can steal from the playbook.

The numbers — and one honest caveat
Every figure in the table above is an estimate from the programme’s economic assessment, presented by FAO Sub-regional Coordinator for Southern Africa Dr Patrice Talla Takoukam at the Legacy Event and reported by The Herald on 9 November 2026. The arithmetic is transparent: about 1,909 extra tonnes of tilapia a year is worth roughly US$3.53 million in additional fish sales, and feed cost savings push the total quantifiable benefit to about US$3.6 million. The benefit–cost ratio of 2.92 to 1 is the assessment’s own figure — hence “almost three dollars for every dollar”, not a round three.
One honest caveat, because the numbers moved as the programme matured. FAO’s own programme page from 1 October 2026 quoted an earlier estimate: production up by just over 1,000 tonnes a year, worth about US$3.03 million in sales, plus about US$57,000 a year in feed savings. The November figures are the final economic assessment, presented as the programme closed, and this post uses those. The direction of travel is the same in both versions — the final assessment simply counts more of the gains.
There is also a bigger number hiding behind the programme. A 2026 FAO technical brief, Zimbabwe: Know your sector, reports that a FISH4ACP frame survey found Zimbabwe’s tilapia farming sector was much larger than anyone had realised — about 8,000 farmers, not the few thousand previously assumed. That survey alone is projected to deliver a 5.9 benefit–cost ratio and a 116% return over five years, by helping government, donors and banks target subsidies, extension services and biosecurity where they are actually needed.
The maggot feed that changed the maths
The single most important innovation was also the strangest-sounding: feeding fish with maggots. Feed is the biggest cost in fish farming everywhere — typically more than half of production cost — and in Zimbabwe expensive commercial feed was pricing small farmers out of the business. FISH4ACP developed and tested feed made from black soldier fly larvae, reared on vegetable waste, which demonstrated the potential to cut feed costs by about 40% while maintaining comparable fish growth.
It worked because it created a business, not just a recipe. Aquaculture entrepreneur Garapo’s business, Aquadelicacy, now supplies the insect-based feed to more than 300 farmers — 44% of them women — turning waste into a product farmers buy because it is cheaper than the alternative. The programme also set up specialised insect enterprises aimed at women and young people who might not own pond land but could supply the growing value chain from its edges. When FISH4ACP first assessed the tilapia value chain, women and youth participation stood at roughly 10%; the programme’s target is to raise it to 40%.
For Indian readers, the lesson is blunt: feed is where fish farming profits are won or lost. India’s own black soldier fly feed experiments exist, but they are still mostly pilot-scale. Zimbabwe shows what happens when insect feed moves from a research paper to a supply chain — farmers adopt it because the price is lower, not because a project told them to.
How the programme actually worked
The money was small — about US$2 million across five years — so it was spent on bottlenecks, not handouts. The sequence matters, and it is a template other countries can copy:
1. Diagnose before spending. The starting point was a value-chain analysis by Chinhoyi University of Technology, which found the two binding constraints: limited access to quality fingerlings and high production costs driven by expensive feed. Everything after that attacked those two problems.
2. Organise farmers into clusters. Working with the Zimbabwe Fish Producers Association, the programme clustered farmers so that services — training, inputs, fingerling delivery — could reach organised groups instead of scattered individuals. Training covered pond management, feeding, record keeping, marketing and business management, not just how to grow fish.
3. Fix fingerlings close to the farmer. Two decentralised fingerling distribution hubs were established by 2025, serving more than 1,000 farmers, and government breeding facilities at Henderson Research Station in Mazowe, Matobo in Matabeleland South and Makoholi in Masvingo were rehabilitated, with fingerling production beginning to emerge from them. A farmer who can buy fingerlings nearby does not lose a week and a fortune transporting them.
4. Build the institution, not just the project. The programme helped establish the Zimbabwe Aquaculture Value Chain Council, bringing farmers, government, researchers and businesses together to keep solving problems after the donor funding ends. As project coordinator Paul Mwera put it at the Legacy Event, the programme’s true legacy “lives in the people empowered”, not in the funds or the infrastructure alone.
5. Count the economics. The programme ran a proper economic assessment — which is why it can say, with evidence, that each dollar returned almost three. Most aquaculture projects never measure this, and so never learn whether they worked.
What happens next in Zimbabwe
The programme is drawing to a close, and the question now is what survives without donor money. The signs are encouraging. Farmers in Masvingo — 12 aquaculture clusters representing more than 500 farmers — have set themselves a target of generating US$1 million for rural households by the end of 2027, under an initiative called “One Fish, One US Dollar” that aims to reach one million fish, led by aquaculture entrepreneur and lead farmer Rudo Maponga. A fingerling distribution hub established in the province under FISH4ACP is already bringing supplies closer to producers.
The government’s ambitions go further. After decades without dedicated fisheries legislation, Zimbabwe is preparing its first Fisheries and Aquaculture Bill, and officials describe a target of building a US$1 billion fish economy by 2032, producing 14,000 tonnes of tilapia a year. FAO has called for increased investment in hatcheries, affordable fish feed, processing, cold-chain infrastructure, access to finance and markets to get there — the same list, in other words, that made the first US$2 million work.
The caution, voiced by the EU’s head of cooperation in Harare, Anna Cichocka, is the right one: “The real success of a development programme is not only what it achieves while funding is available, but what continues to work long after the programme has ended.” Zimbabwe’s demand side helps — growing demand for fish is still substantially met through imports, so there is a market waiting for every extra tonne local farmers can produce.
What Indian fish farmers can steal from this
India’s aquaculture sector is vastly bigger than Zimbabwe’s, but the problems rhyme. Four lessons travel well:
Attack feed cost first. Feed is the largest single cost in Indian fish farming too. Black soldier fly larvae, reared on vegetable and food waste, is a proven way to cut it — Zimbabwe’s 40% figure is a potential, not a guarantee, but even half of that transforms a pond’s economics. Farmers and startups working on insect feed in India should note that the winning model was a local feed business, not a subsidy.
Cluster, don’t scatter. Zimbabwe’s farmer clusters made training, fingerling delivery and input supply affordable to deliver. India’s farmer producer organisations and self-help groups do the same job where they work well — the Zimbabwe experience is a reminder to build the group before the scheme, not after it.
Put fingerlings near the farmer. Decentralised fingerling hubs cut transport losses and costs. India’s hatchery network is far larger, but the last-mile problem — quality seed reaching a remote pond on time — is identical. Hubs close to farming clusters beat one big hatchery far away.
Measure the return. FISH4ACP can prove its 2.92-to-1 return because it measured it. Indian schemes rarely publish benefit–cost ratios at all. A programme that cannot show its return cannot defend its budget — or learn from its mistakes.
Frequently asked questions
What is FISH4ACP?
Fisheries for African, Caribbean and Pacific countries — a global development initiative of the Organisation of African, Caribbean and Pacific States (OACPS), implemented by FAO and funded by the European Union and Germany’s BMZ. In Zimbabwe it worked on the farmed tilapia value chain.
Did Zimbabwe really earn US$3.6 million from a US$2 million investment?
The US$3.6 million a year is an estimate from the programme’s economic assessment: about US$3.53 million in extra fish sales plus feed cost savings. The benefit–cost ratio is 2.92 to 1. It is a modelled estimate, not audited cash in a bank account — but it is the programme’s own final assessment, and the earlier FAO estimate pointed the same way.
What is black soldier fly feed?
Feed made from the larvae of the black soldier fly, reared on vegetable waste. It is high in protein, and in Zimbabwe’s trials it cut feed costs by about 40% while fish grew just as well as on commercial feed.
Can Indian farmers use the same approach?
Yes — the techniques (insect feed, farmer clusters, decentralised fingerling hubs) are all transferable, and black soldier fly feed trials already exist in India. The Zimbabwe lesson is to build them as businesses and supply chains, not as one-off demonstrations.
What is Zimbabwe aiming for next?
A first Fisheries and Aquaculture Bill, a US$1 billion fish economy by 2032, and 14,000 tonnes of tilapia a year. Farmers in Masvingo alone are targeting US$1 million for rural households by the end of 2027.

All facts above were verified on 11 November 2026 against the sources listed. The US$3.6 million a year and the 2.92-to-1 benefit–cost ratio are estimates from FAO’s economic assessment as reported at the FISH4ACP Zimbabwe Legacy Event — not audited revenue — and the post says so explicitly. FAO’s earlier October 2026 page quoted lower figures (just over 1,000 extra tonnes, US$3.03 million in sales); this post uses the final November assessment and notes the difference.
