Bluefin Tuna Return Marks Conservation Milestone Off Yorkshire

Earlier this week, two giant Atlantic bluefin tuna were landed by a commercial vessel near Whitby, the first such catch for market from the North Sea since licences were issued in July. The fish were taken a day apart and represent the first recorded capture off the Yorkshire coast since the 1960s.

Bluefin tuna were heavily fished in their Mediterranean spawning grounds throughout the 1970s and 1980s, driving the species toward local extinction. Conservation measures led by the International Commission for the Conservation of Atlantic Tunas (Iccat) have helped rebuild stocks across the Atlantic. Researchers note that other marine species, such as minke whales and bottlenose dolphins, have also increased around the North Sea over the past decade, suggesting broader ecosystem recovery.

Both Whitby tuna weighed about 320 kg (700 lb) each, roughly double the average size of bluefin caught off England’s south coast. The catches occurred only a day apart, marking the first documented pair of marketable specimens in the region in more than sixty years.

Rodney Forster, professor at the University of Hull and head of the Hull Marine Laboratory, described the reappearance as evidence that fisheries management can reverse severe declines. Bryce Stewart of the Marine Biological Association highlighted the role of warmer North Sea temperatures in boosting prey species such as herring and sprat, creating a “knock-on effect” that benefits tuna. Calum Duncan, principal policy specialist at the Marine Conservation Society, stressed that the tuna’s continued survival will depend on sustained protection measures and stronger British fishing policies.

• “It seemed like an era that had gone for ever, you know, I mean normally if we lose a large species like this from an area of sea, they don’t come back,” — Bryce Stewart
