The owners of a supertrawler, based in Hull, have hit out at the collapse of fishing talks with Norway, which has left hundreds of crewmen without work.
The failure to reach a deal means fish and chip shops will be selling Arctic cod imported from Norway rather than landed in Britain, UK Fisheries said.
Giant vessel Kirkella, which normally catches around 10% of all the fish sold in the UK's chip shops, is now tied up in Hull without any viable long-term opportunities.
But to provide British fish for chippies, the Kirkella needs access to quotas from the Faroe Islands, Greenland and Norway.
The Department for Environment, Food and Rural Affairs (Defra) said the UK and Norwegian positions were too far apart to reach an agreement this year.
No access or quota exchange agreements have been reached with the Faroes either.
Keir Starmer, who was visiting Hull on Friday, said: "Boats, fishing communities are now tied up, can't go out and do their business. They have been betrayed."
UK Fisheries chief executive Jane Sandell said Environment Secretary George Eustice owed an explanation to the industry.
"This is a very black day for Britain," she said.
"George Eustice owes our crews and the Humberside region an explanation as to why Defra was unable even to maintain the rights we have had to fish in Norwegian waters for decades, never mind land the boasts of a 'Brexit bonus', which has turned to disaster."
Her Hull-based company employs approximately 100 crew. She said the news would be "absolutely devastating" for those workers and their families.
The board of UK Fisheries will now meet to decide what presence it can have in Hull with no viable fishing opportunities in its traditional grounds.
Meanwhile, Conservative Lincolnshire MP Victoria Atkins said this is part of a tricky negotiating landscape.
She said: "We ask fishermen to keep their faith with us and we will be representing their interests on the international stage."
A Defra spokesman said: "We have always been clear that we will only strike agreements if they are balanced and in the interests of the UK fishing industry.
"We put forward a fair offer on access to UK waters and the exchange of fishing quotas, but we have concluded that our positions remain too far apart to reach an agreement this year.
"Norway is a key partner and we will continue to work with them over the course of the year."
