In 1970, the UK’s sovereign waters were signed over to European control by former prime minister Edward Heath.
Many fishermen believe EU rules imposed on Britain have led to the decline of the fishing industry within the country.
Now, some fear control of the UK’s waters may be used as a bargaining chip to strike a trade deal with Brussels during the forthcoming Brexit negotiations.
Aaron Brown, from the campaign group Fishing for Leave, now wants Theresa May to use Brexit as a chance to spur a revival of the country’s floundering fishing industry.

He told the BBC’s Daily Politics show: “Article 50 gives us a clean slate to leave, the EU’s agreed that, but if we readopt all the legislation then we’ve effectively re-agreed to it and nailed our feet to the floor.
“Fishing needs to be exempt from the Great Repeal Bill, otherwise we’ll still be in the CFP.”
The EU’s CFP sets the quantities and the kinds of fish British fisherman are allowed to catch in UK Waters.

Mr Brown argued British seas should not be up for negotiations unless a fair deal is struck in return with the EU.

“To begin with only UK vessels should have access, there after, we can do the same as what Norway, Iceland and Faroe do and negotiate on an equal exchange on a barter basis with the EU,” he continued.
“The government’s got to scrap quotas, quotas cause discards, we need to move to days at sea meaning vessels can catch more but land less.
“We’d be able to retain all the fish we catch, instead of having to discard under quotas where you have to steam all over the sea catching more and more fish just to find what you’re allowed to keep.”

Ukip's Mike Hookham said Britain's fisheries was "red line"
The Brexit White Paper revealed the UK Government is aiming to reach a “mutually beneficial” deal with the bloc regarding fishing.
Two-thirds of Britain's fish caught are currently exported to the EU, so it’s likely the industry will still be tied to the continent after negotiations are complete.
But, the idea of once again negotiating away control of Britain’s waters was rebuked by Ukip’s spokesman on fisheries Mike Hookem, who said: “As a party what we are saying is this is a red line which should not be crossed.
“These are our waters, they’re our fish, we want them back and this has to be in the Brexit negotiations a red line and we aren’t going to retreat on this."
