Octopuses, sharks and tuna that are booming in the sea around the UK could be part of a fundamental shift in the marine environment, a leading scientist has told Sky News.
Dr Simon Thomas, from the Marine Biological Association in Plymouth, said a perfect storm of factors, including climate change and overfishing, is leading to a rapid change in the species being found around the coast.
“Since 2016, you’ve seen a lot of our traditional fish, like cod, ling and pollock decreasing in numbers and pushing northwards,” he said.
“Then we’ve seen other fish, especially things like bluefin tuna and blue sharks, being found in huge numbers in the water here.
“It’s almost like you’ve seen a complete shift in the regime of the ocean.”
‘I’ve never seen anything like it’
Fishermen on the south coast of Devon and Cornwall are currently catching huge numbers of a large octopus species that is normally rare in the UK.

“I’ve never seen anything like it in my lifetime,” said Dr Thomas.
“I’ve spent 40 years at sea and probably seen three or four of the big octopus over the years. Now they are seen regularly and (crab fishermen) are reporting their pots have been decimated.”
The octopuses are raiding crab and lobster pots for an easy meal.

But there are so many of them, and they are so hungry, that fishermen say they are eating not only the bait and crustaceans, but also, at times, each other.
Sam Jago, skipper of the Bosloe, returned to Plymouth after a day’s fishing with 11 crates of octopuses – a 400kg bonanza that could fetch almost £3,000 at market rates.
But he had just over one tub of crabs and lobsters – when normally he’d have more than a dozen.

“They crack the shell and suck everything out of it,” he said.
“It’s a quick buck at the moment, but who knows how long it’s going to last for.
“They will stay here until they’ve eaten everything.
“But if the octopus go, the crab isn’t going to just appear out of thin air.
The Marine Biological Association is studying factors that could underpin the surge in octopus numbers.
The sea around the UK is around 2C warmer than normal. But in the southwest of England the temperature is 3C or even 4C above average for the time of year.
Dr Thomas said warmer waters increase survival of young octopus fry over winter, and a change to ocean currents could bring them more food.

‘The ocean is changing’
Overfishing of species that would normally eat young octopuses may also mean more are surviving to adulthood.
“There is no doubt that the ocean is changing,” he said.
“Fishermen are like the canaries in the coal mine, the first to see things changing out at sea.”
Scientists say protecting key parts of the ocean as marine nature reserves would serve as a buffer against pressures from human activity elsewhere.
So far, 50 nations plus the EU have ratified the United Nations High Seas Treaty that commits countries to protect 30% of the ocean by 2030.
Another nine need to ratify it for it to become operational.
The UK government has said it will ratify the treaty by the end of the year.
A nationwide police operation to track down those in grooming gangs has been announced by the Home Office.
The National Crime Agency (NCA) will target those who have sexually exploited children as part of a grooming gang, and will investigate cases that were not previously progressed.
Home Secretary Yvette Cooper said in a statement: “The vulnerable young girls who suffered unimaginable abuse at the hands of groups of adult men have now grown into brave women who are rightly demanding justice for what they went through when they were just children.
“Not enough people listened to them then. That was wrong and unforgivable. We are changing that now.
“More than 800 grooming gang cases have already been identified by police after I asked them to look again at cases which had closed too early.
“Now we are asking the National Crime Agency to lead a major nationwide operation to track down more perpetrators and bring them to justice.”

Starmer to launch new grooming gang inquiry
The NCA will work in partnership with police forces around the country and specialist officers from the Child Sexual Exploitation Taskforce, Operation Hydrant – which supports police forces to address all complex and high-profile cases of child sexual abuse – and the Tackling Organised Exploitation Programme.
It comes after Sir Keir Starmer announced a national inquiry into child sex abuse on Saturday, ahead of the release of a government-requested audit into the scale of grooming gangs across the country, which concluded a nationwide probe was necessary.
The prime minister previously argued a national inquiry was not necessary, but changed his view following an audit into group-based child sexual abuse led by Baroness Casey, set to be published next week.
Ms Cooper is set to address parliament on Monday about the findings of the near 200-page report, which is expected to warn that white British girls were “institutionally ignored for fear of racism”.
One person familiar with the report said it details the institutional failures in treating young girls and cites a decade of lost action from the Independent Inquiry into Child Sexual Abuse (IICSA), set up in 2014 to investigate grooming gangs in Rotherham.
The report is also expected to link illegal immigration with the exploitation of young girls.
Career spy Blaise Metreweli will become the first woman to head MI6 in a “historic appointment”, the prime minister has announced.
She will take over from Sir Richard Moore as the 18th Chief, also known as “C”, when he steps down in the autumn.
“The historic appointment of Blaise Metreweli comes at a time when the work of our intelligence services has never been more vital,” Sir Keir Starmer said in a statement released on Sunday night.
“The United Kingdom is facing threats on an unprecedented scale – be it aggressors who send their spy ships to our waters or hackers whose sophisticated cyber plots seek to disrupt our public services.”
Of the other main spy agencies, GCHQis also under female command for the first time.
Anne Keast-Butler took on the role in 2023, while MI5 has previously twice been led by a woman.
Until now, a female spy chief had only headed MI6– also known as the Secret Intelligence Service (SIS) – in the James Bond movies.

Dame Judi Dench held the fictional role – called “M” in the films instead of “C” – between 1995 and 2015.
Ms Metreweli currently serves as “Q”, one of four director generals inside MI6.
The position – also made famous by the James Bond films, with the fictional “Q” producing an array of spy gadgets – means she is responsible for technology and innovation.
Ms Metreweli, a Cambridge graduate, joined MI6 in 1999.
Unlike the outgoing chief, who spent some of his service as a regular diplomat in the foreign office, including as ambassador to Turkey, she has spent her entire career as an intelligence officer.
Much of that time was dedicated to operational roles in the Middle East and Europe.
Ms Metreweli, who is highly regarded by colleagues, also worked as a director at MI5.
In a statement, she said she was “proud and honoured to be asked to lead my service”.
“MI6 plays a vital role – with MI5 and GCHQ – in keeping the British people safe and promoting UK interests overseas,” she said.
“I look forward to continuing that work alongside the brave officers and agents of MI6 and our many international partners.”
Sir Richard said: “Blaise is a highly accomplished intelligence officer and leader, and one of our foremost thinkers on technology. I am excited to welcome her as the first female head of MI6.”
A woman has died after falling into the water at a popular beauty spot in the Scottish Highlands.
The 23-year-old had fallen into the water in the Rogie Falls area of Wester Ross.
Police Scotland confirmed emergency services attended the scene after being called at 1.45pm on Saturday.
“However, [she] was pronounced dead at the scene,” a spokesperson said.
“There are no suspicious circumstances and a report will be submitted to the Procurator Fiscal.”
Rogie Falls are a series of waterfalls on the Black Water, a river in Ross-shire in the Highlands of Scotland. They are a popular attraction for tourists on Scotland’s North Coast 500 road trip.
