EYEMOUTH, Scotland (AP) – In their drive to uncouple Britain from the European Union, pro-Brexit campaigners have turned fishing into one of their battlegrounds. But while some seafood industry workers want out of the EU, others are alarmed at the prospect of losing frictionless access to EU consumers. Seafood harvested from Scottish waters must be whisked quickly to EU markets to stay fresh, but Brexit could create problems. A holdup on the long, usually obstacle-free journey, even of just half a day, can be fatal for the fragile critters, turning prized seafood into worthless waste. On Friday, Prime Minister Boris Johnson visited a fish market in Scotland to meet with people in the industry after bruising week in Parliament where he is struggling to keep his Brexit plans on track.
