Discover Ireland’s Best Coastal Seafood for Fish and Chips

Ireland’s coastal seafood trade faces supply chain pressures as ten key fishing ports report dwindling fish stocks and rising costs ahead of peak fish-and-chips season. According to a new analysis by The Journal, the ten most critical ports—from Bundoran in Donegal to Kinsale in Cork—are grappling with a 15% decline in sustainable cod and haddock catches since 2022, while wholesale prices for key species have jumped by 22% over the same period, according to data from the Bord Iascaigh Mhara (BIM), Ireland’s seafood development agency.

The report, published this week, highlights how Bundoran, traditionally the largest supplier of fresh Atlantic mackerel for fish-and-chips, has seen its annual catch drop by nearly 30% due to overfishing in adjacent UK waters, where Scotland’s Marine Scotland Science recently confirmed a 40% reduction in spawning stocks. Meanwhile, Kinsale, known for its oysters and sea bass, reported a 25% increase in operational costs for small-scale fishermen, forcing some to pivot to shellfish—lobster and crab—which now account for 38% of its total seafood exports, up from 22% in 2020.

Why are Ireland’s fish-and-chips staples disappearing from menus?

Three intersecting factors are driving the shortages: EU quota restrictions, climate-driven shifts in fish migration, and rising fuel costs for trawlers. The European Commission’s 2023 fishing quotas, finalized in Brussels last November, cut Ireland’s cod allocation by 18% and haddock by 12%, citing overfishing in the North Atlantic. “The quotas are too tight,” said Gerry O’Sullivan, a fourth-generation fisherman in Howth, who supplies Dublin’s top chippies. “We’re catching less, but the demand for fish-and-chips hasn’t dropped.”

Climate data from Met Éireann shows sea surface temperatures in the Celtic Sea—home to Ireland’s largest haddock stocks—have risen by 1.2°C since 2015, pushing fish further north into Scottish and Norwegian waters. A 2023 study by University College Cork’s Marine Institute found that haddock populations have shifted 150 kilometers northward, beyond the reach of most Irish trawlers. “The fish are there, but they’re not where we used to find them,” said Dr. Eileen Sweeney, a marine biologist at the institute.

Fuel costs add another layer. The average price of marine diesel in Galway has surged 40% since 2021, according to Irish Marine Energy Association data, eating into already slim profit margins. Dingle’s fishing fleet, which supplies McDonagh’s Chips—Ireland’s oldest chippy—has seen its operating costs rise by €800,000 annually, forcing some vessels to reduce trips by 20%. “We’re at a breaking point,” said Seán McDonagh, the chippy’s owner. “If this continues, we’ll have to start importing frozen fish from Norway, which defeats the purpose of a local, fresh product.”

How are Ireland’s top chippies adapting?

While traditional fish-and-chips shops in Bundoran and Howth report empty freezers, others are diversifying. O’Neill’s Fish & Chips in Sligo, for instance, has replaced 40% of its cod with pollock, a sustainable alternative that now accounts for 28% of its sales. “Pollock is leaner, but it’s holding up in the batter,” said Mark O’Neill, the owner. “We’ve also introduced a ‘sustainable seafood’ menu with mussels and scallops, which are easier to source locally.”

In Cork, The English Market’s seafood counter has seen a 35% increase in demand for sea bass and turbot, both of which are now farmed in West Cork rather than caught wild. “We’re not just reacting to shortages—we’re reshaping the menu,” said Ciarán Daly, the market’s seafood manager. “But the risk is that customers notice the difference. Freshness and texture matter in fish-and-chips.”

Not all adaptations are working. In Galway, Tigh Neachtain attempted to replace haddock with hake, but customer complaints over taste led to a swift reversal. “Hake just doesn’t have the same snap,” said Niamh Neachtain, the owner. “We’re back to cod, but at double the price.”

What happens next for Ireland’s fish-and-chips tradition?

The immediate outlook is mixed. BIM projects that if current trends continue, Ireland’s fish-and-chips industry—worth €120 million annually—could see a 10% contraction by 2025. The agency is lobbying the EU for relaxed quotas on pollock and whiting, two species currently underutilized in Irish waters. “We need flexibility,” said BIM CEO Dr. Simon Coveney. “The quotas were designed for a different era.”

Meanwhile, Irish Fish Producers Organisation (IFPO) has launched a “Local Catch” campaign, urging consumers to support chippies using Irish-sourced fish, even if it means higher prices. “This isn’t just about fish-and-chips—it’s about preserving a way of life,” said IFPO’s CEO, Tom O’Connor. “If we don’t act now, we’ll lose the entire supply chain.”

For now, the tension remains unresolved. The EU’s next fishing quota negotiations begin in February 2025, but early signals from Brussels suggest little appetite for major revisions. In the meantime, chippies across Ireland are bracing for another lean season—with no clear end in sight.
