Fishing was a powerful factor in the case for leaving the EU. On the eve of crucial trade talks, the Observer finds optimism tempered by caution on the quays of Devon and Cornwall

Neil Watson was eight or nine when his dad took him out to sea for the first time. Soon he was earning his first pocket money by washing fish boxes on the quay at Brixham in south Devon. Three years after he started crewing, he got his skipper’s ticket and eventually he bought his own boat. For 30 years, he regularly spent seven days at sea followed by one night off, only stopping when his boat sank two years ago.

“I fished through good times and bad times. Fishing’s like riding a wave – one minute you’re up the top, and the next you’re down in the trough,” he said. Now Watson works at Brixham’s fish market, one of the largest in England, where £40m of fish was sold last year across the UK and Europe. A fisherman’s life is brutal, he said, but he badly misses the camaraderie.
