Four in five people want “destructive” supertrawlers banned from fishing in the UK’s marine protected areas (MPAs), a poll shows.

The huge boats – the largest of which is more than 465ft long – have been the subject of controversy due to their ability to “vacuum” up huge quantities of fish every day.

There have been calls to use new Brexit powers to ban them from marine protected areas, or from UK waters altogether.

The vessels’ presence off the UK coast has led to fears over fishing stocks and spikes in numbers of dolphin deaths.

Now, a YouGov poll commissioned by Greenpeace reveals that four in five members of the British public want the factory ships banned from fishing in the UK’s MPAs.

MPAs protect important marine ecosystems and species, including porpoises and reefs.

A petition to ban supertrawlers from MPAs launched by Greenpeace last week has gathered more than 130,000 signatures.

Philip Evans, an oceans campaigner at Greenpeace UK, said: “This polling makes absolutely clear that the public is united behind our call for a ban on supertrawlers fishing in protected areas.

“After a decade of political division, our call cutting across the political divide should send a firm message to the Government that enough is enough.

“Supertrawlers must be banned from our protected areas.”

The poll of 1,664 people undertaken by YouGov reported that 81% said supertrawlers should be banned from fishing in protected areas, with 4% saying they should be permitted to fish in them.

When broken down by political sympathies, the data showed that 81% of Labour voters, 85% of Conservative voters and 87% of Lib Dem voters support a ban.

With regards to Brexit, it was found that 83% of Remain supporters and 87% of Leave supporters also support a ban.

Mr Evans added: “Britain’s departure from the EU’s Common Fisheries Policy is the perfect opportunity to do this.

“Our Government should listen to its constituents, and commit to banning supertrawlers from protected areas as a first step towards designating a network of fully or highly protected MPAs off-limits to all destructive activity across 30% of the UK’s waters.”

A Defra spokesperson said: “The UK is a global leader in the fight to protect our seas with our ‘Blue Belt’ of protected waters nearly twice the size of England.

“The Common Fisheries Policy currently restricts our ability to implement tougher protection, but leaving the EU and taking back control of our waters as an independent coastal state means we can introduce stronger measures.”
