Picture two very different boats. One is a small day boat, maybe under 40 feet, run by a family that’s fished the same stretch of coast for generations — heading out at dawn and back by dinner. The other is a large commercial vessel, hundreds of feet long, working far offshore for days or weeks at a time and hauling in enough fish to feed a city.
It’s tempting to look at those two boats and sort them into a hero and a villain. In fact, most people do. There is a common belief that big = bad, small = good. Small and local feels virtuous; big and industrial feels like something to worry about. But that instinct, as understandable as it is, isn’t quite accurate.
Just like everything in seafood, it’s a bit more nuanced than that.
Before we get into why, let’s start with the basics: what actually are these two things?
So what actually makes a fishery “small-scale” or “large-scale”?
Where do we draw the line between a “small-scale” fishery and a “large-scale” fishery. If you’re keeping up, there’s only one right answer: it’s complicated! (Welcome to the seafood industry!)
The UN’s Food and Agriculture Organization (FAO) — the body that tracks the world’s fisheries — deliberately avoids drawing one hard line, because what counts as “small-scale” in one country can look different in another.
Instead, FAO characterizes small-scale fisheries by their nature, noting they “tend to be strongly anchored in local communities, reflecting often historic links to adjacent fishery resources, traditions and values.” By FAO’s estimate, these fisheries account for about half of the world’s total catch — and roughly two-thirds of the catch destined for direct human consumption.
Large-scale fisheries sit at the other end of that same spectrum: bigger, more capital- and technology-intensive operations built for volume and range. The line between them is a gradient, not a fence — but here’s the picture at each pole.
Small-scale fisheries (sometimes called artisanal fisheries) are operated by countless individuals, small local fishing cooperatives, and subsistence fishers, usually working from smaller boats — and sometimes no boat at all, just people harvesting by hand along the shore. They tend to stay close to home, in coastal and inland waters, using lower-energy gear like traps, handlines, small nets, and pots. They’re often family-run and community-rooted, and almost everything they catch goes straight to feeding people. Remarkably, they provide a vital source of income for over 90% of the world’s fishers.
Large-scale fisheries (also called industrial fisheries) are the bigger vessels built to travel farther, stay out longer, and bring back high volumes. Many are high-capacity ships equipped to freeze and process seafood right on board — the largest can stretch over 130 metres long, hold more than 2,000 tonnes of fish, and stay out at sea for long stretches with sizeable crews catching and processing around the clock. They can reach offshore stocks that small boats simply can't, and they supply the steady, large-scale flow of seafood that fills grocery stores, restaurants, and export markets around the world.
“Which one is better?” is the wrong question
We love a good-versus-bad story. Big industrial fishing makes an easy villain, and the little wooden boat makes an easy hero. But the moment you look closely, the story falls apart — because scale, all by itself, tells you almost nothing about whether a fishery is sustainable.
There are small-scale fisheries that are beautifully managed, and small-scale fisheries that are overfished and unregulated. There are large-scale fisheries that are among the most carefully monitored operations on the planet, and large-scale fisheries that have done real damage. The size of the boat isn’t what makes seafood a good choice. How that fishery is managed is what makes it a good choice.
Humans eat a lot of seafood, and we’re eating more of it than ever. According to the FAO’s State of World Fisheries and Aquaculture 2026, the world now produces around 235 million tonnes of fish and aquatic animals a year — an all-time high. The average person eats roughly 21 kilograms of seafood a year, and aquatic foods supply at least a fifth of the animal protein for about 3.1 billion people. The sector supports more than 600 million livelihoods worldwide.
Feeding that much seafood to that many people is an enormous job — far too big for any single kind of fishing to handle alone. It takes small boats and large vessels.
We need both
If you’ve been here for a while, you’ve heard me say this a million times; “we need both”. We need farmed and wild seafood, we need fresh and frozen seafood, we need domestic and imported seafood, and, we need small scale and large scale fisheries.
While it can sometimes seem complicated, this diversity is the biggest strength of the global seafood system.
The case for small-scale: these fisheries are the quiet backbone of the entire seafood world, and the numbers are genuinely staggering. They provide the majority of the world’s fishing jobs — supporting about 90% of everyone employed in capture fisheries, roughly 60 million people working directly in the catch, plus tens of millions more in subsistence fishing. Around the world, an estimated 490 million people depend at least partly on small-scale fisheries for their livelihoods — about 1 in every 12 people on Earth.
They’re also a food-security powerhouse that rarely gets credit for it. Small-scale fisheries land at least 40% of the world’s wild catch, and almost every bit of it goes directly onto people’s plates rather than into fishmeal or animal feed. For coastal and inland communities, they supply over half of the aquatic food people eat locally, delivering hard-to-get micronutrients — iron, zinc, omega-3s, vitamin B12 — to billions of people who need them most.
And they’re powered by women far more than most people realize. Nearly half of everyone working across small-scale fisheries is a woman, and women dominate the processing and selling side that gets the catch to market. On top of all that, small-scale fishing tends to be low-impact and remarkably fuel-efficient, it keeps food close to the communities that catch it, and it carries traditions and flavours no large operation can replicate.
The case for large-scale: these fisheries are how we feed billions affordably and consistently. They reach fish stocks that are out of range for small boats, they deliver seafood at a price and volume that keeps it on everyday plates, and — when they’re well-managed — they can be remarkably efficient and sustainable. They’re what makes seafood available in the middle of winter, a thousand miles from the coast, at a price a family can plan around.
Lean on only small-scale fishing, and you can’t come close to feeding a planet of eight billion people. Lean on only large-scale fishing, and you hollow out coastal communities and lose the diversity, resilience, and local knowledge that keep the whole system healthy. Together, they cover for each other’s limits.
How both can be sustainable
Sustainability isn’t about size. It’s about management.
Small-scale fisheries are often naturally low-impact — they use selective gear, burn far less fuel per pound of fish, and generate very little waste, with almost all of their catch going directly to people rather than to feed. Their challenge is usually visibility: because they’re spread across thousands of small landings, they can be harder to track and formally manage, which is exactly why good local rules — seasons, gear limits, community stewardship — matter so much.
Large-scale fisheries can be sustainable too, and some of the best-managed fisheries on the planet are large. Take Alaska pollock, the single biggest fishery in the United States: it’s a massive, high-volume, industrial operation — and it’s independently certified as sustainable, with tightly enforced science-based catch limits. Big and well-run are absolutely allowed to be the same sentence. The real risks on the large-scale side — overcapacity, bycatch, too much of the catch diverted to fishmeal — are problems of poor management, not of size itself.
Which brings us right back to the point: a responsibly managed large-scale fishery can be a better choice than a poorly managed small-scale one, and vice versa. Scale is not the scorecard. Management is.
How to shop with confidence
You don’t need to memorize boat lengths to make a good choice. Here’s the short version:
- Judge by how it was managed — not how big the boat was. A well-run large-scale fishery and a well-run small-scale one are both great choices.
- Look for credible certifications. An MSC label on wild seafood means an independent body checked that the fishery is sustainably managed, at any scale.
- Buy local when you can find it. Day-boat and community-supported catches are a wonderful way to support nearby fishing families — and the seafood is often stunningly fresh.
- But don’t feel guilty about the big fishery, either. Well-managed large-scale seafood is affordable, reliable, and doing essential work. It belongs in your cart too.
- Try a diversity of species. Spreading your choices across the seasons and the scales keeps demand balanced and your meals interesting.
The bottom line
Small-scale and large-scale fisheries aren’t a competition, and you don’t have to pick a team. One connects us to our coastlines and the communities that fish them; the other feeds the world at a scale nothing else can match. One brings variety and tradition; the other brings volume and reliability. We need both — and both can be done well.
So the next time you’re at the counter, don’t ask whether the fish came from a big boat or a little one. Ask whether it was caught responsibly. If the answer is yes, you’re making a good choice — no matter the size of the boat that brought it in.
