José Correia of Angeiras, a tiny fishing village on Portugal's northern coast, watches his son consider a future far from the sea. The work that once sustained generations is now physically demanding, poorly paid and increasingly marginalised. In his community, only five or six young people still own a boat.

This local story mirrors a continent‑wide shift. According to the environmental watchdog Seas At Risk, small boats account for roughly 76% of the European Union's active fishing fleet and employ almost half of the sector's workforce, yet they deliver only about 7% of the total catch by weight. The remaining 93% is harvested by a relatively small number of large vessels, many owned by multinational corporations.

Corporate concentration squeezes artisanal catches

Data from the European Commission show that five Dutch groups now control around 16% of the EU fleet when measured in tonnes. Their dominance is felt most acutely in the Mediterranean, the Baltic and the Black Sea, where the value of small‑scale catches fell by 30%, 36% and 50% respectively between 2018 and 2022.

Brian O'Riordan, policy adviser at Low Impact Fishers of Europe (LIFE), describes the sector as being at a "crossroads". Over‑fishing, climate‑driven changes in water temperature and salinity, and pollution have already reduced fish stocks. On top of that, small operators struggle to obtain quotas, access markets and influence policy decisions.

Quotas, the legally defined limits on how much of a species may be taken, were introduced to protect marine resources, but they have become a tradable commodity. Larger firms with deeper pockets buy up allowances from struggling fishers, often leaving coastal communities bereft. "Some northern Danish harbours lost their fishing communities as people sold quotas and left," explains Bruno Nicostrate, senior fisheries policy officer at Seas At Risk. "They might do it to change jobs, make a profit or simply retire, but the result is the same, a loss of local knowledge and culture."

Impact on livelihoods and the environment

For the remaining artisanal fishermen, the daily reality is increasingly precarious. In the Algarve, Portuguese fisherman Jorge Fernandes prepares his nets for another day at sea and laments that "big players buy at whatever price they want. It's all in their hands." He is not alone; many small‑scale fishers accept lower earnings simply to keep a family tradition alive.

In Galicia, Spain, the decline is visible in the shell‑fishing sector, traditionally dominated by women. Sandra Menéndez, spokesperson for the association Mulleres Salgadas, tells us that many women now feel "abandoned" as policies tilt in favour of large aquaculture enterprises. The loss of marisqueo not only erodes cultural identity but also removes a source of relatively low‑impact protein for local markets.

Ecologically, small boats are gentler on marine ecosystems. They use less fuel, generate fewer by‑catches and cause fewer discards. By contrast, super‑trawlers can sweep vast swathes of water, depleting stocks and disrupting habitats. "Supertrawlers have no place in sustainable fishing. They should not exist," says Nicostrate.

Climate change compounds these pressures. Warmer waters and altered salinity patterns, driven by intense rainfall, shift fish migration routes and reduce the predictability of catches. Small operators, lacking the capital to invest in new gear or to travel farther offshore, are hit hardest.

Consumers left in the dark

When shoppers pick up a packet of cod or a fillet of hake, EU labelling rules oblige the retailer to indicate the species, the region of capture and the gear used. What the label does not reveal is whether the fish came from a modest family‑run boat or a corporate super‑trawler. Unlike egg cartons that display free‑range or cage‑free claims, fish labels provide no insight into the scale of the operation.

Intermarché, a major French retailer, illustrates the opacity. The chain owns the fishing fleet Scapêche, which can afford to sell fish at low margins, or even at a loss, because it recoups profit further down the supply chain. BLOOM, an NGO campaigning for ocean health and the rights of artisanal fishers, warns that such arrangements allow large retailers to undercut independent fishers while remaining invisible to the consumer.

Without clear information, European households cannot make informed choices about the social and environmental footprint of the seafood they purchase. This lack of transparency fuels the market power of a few corporations and deepens the marginalisation of small‑scale fishers.

Policy debate and possible remedies

The European Commission is aware of the imbalance. Recent proposals aim to tighten the rules on quota transfers, limiting the amount that can be sold to non‑fishing entities. Some member states, such as Portugal and Spain, already impose stricter caps, but enforcement remains uneven.

Trade unions and fishermen's cooperatives argue for a "quota reserve" that would be set aside exclusively for small‑scale operators, ensuring they retain a baseline of fishing rights. Others call for a "fair‑trade" label for seafood, similar to those used for coffee and chocolate, which would certify that the product originates from a small, sustainable operation.Critics of tighter regulation warn that excessive restrictions could push small fishers out of the market entirely, especially if they cannot compete on price. They suggest that subsidies for modernising vessels, investment in cold‑chain infrastructure and direct‑sale platforms (such as fish boxes delivered to households) could help level the playing field.

Regardless of the approach, the underlying challenge is to reconcile the EU's ambition for sustainable fisheries with the social reality of coastal communities that have depended on the sea for centuries. As O'Riordan notes, the sector is "at a dire point", and the choices made in Brussels will determine whether small‑scale fishers survive or become a footnote in maritime history.

For consumers, the message is clear: the next time you reach for a piece of fish, consider asking the retailer about the origin of the catch. Transparency could become a lever for change, encouraging supermarkets to source from smaller, environmentally‑friendly boats and giving a voice back to the fishermen whose livelihoods are currently being swallowed by corporate fleets.
