So long and thanks for all the fish?

"Very worried of course about Brexit," says Barend Hakvoort, whose job it is to ensure the Netherlands' largest fish auction house maintains its stocks.

"Many Urk people are fishing under a UK flag, they own a lot of quota. If the UK says they must land the fish in the UK we lose a lot of clients. We have a long history; with Brexit they can just throw it away and say these are the new rules."

Skipper Andries wears a tartan beret and gold-hoop earring. "If we lost the UK waters we'd lose 50% from Dutch vessels. I'm nervous, I don't know what the future brings."
