North Sea Case Study

Led by Heriot-Watt University

Overview: The North Sea is one of the world’s most heavily exploited marine areas. Its shared fish stocks support valuable demersal mixed fisheries, including cod, haddock, whiting, saithe, hake, and anglerfish, fished by multiple countries using different gear types.

Challenges: Climate change is shifting fish distributions northward, complicating quota management. Mixed fisheries face bycatch, discarding, and choke species, which current landing obligations do not fully address.

Solutions: Use climate-informed ecosystem models to track and forecast stock shifts, improve advice for mixed and choke-species fisheries, and develop bycatch-reducing gear and technologies.
