Adding to the mix – Challenges of mixed‐fisheries management in the North Sea under climate change and technical interactions
Abstract Technical interactions (multiple fleets fishing multiple species with various gears, as either target or bycatch), bycatch regulations through a landing obligation, and biological and economic effects of climate change, affecting fisheries yield and profits, provide a challenge for demersal...
