The Marine Conservation Society (MCS) has warned that rising sea temperatures due to global warming are causing dramatic reductions in cod species. Charlotte Coombes, of MCS, said Express.co.uk that cod populations in UK waters are “among the lowest on record” in some areas. Cod is a cold-water species, so rising sea temperatures have put its population at risk, with too hot temperatures reducing the survival rate of juveniles.
Ms Coombes also warned that other parts of UK waters are also seeing cod populations decline.
She said: ‘Off the south-west of the UK, in the Celtic seas around Cornwall, this population is also extremely low and at risk of not being able to breed, and the same is true off the coast. west of Scotland.
âWhen populations get this small, they can’t actually find themselves to reproduce, and once they get to that point, they risk collapsing and disappearing altogether if they don’t find a way to increase the number again. population size. “
The MCS has already made a list of âfish to avoidâ on its Good Fish Guide.

Both North Sea and Celtic Sea cod are on the Red List, with the UK’s only other cod stock in the Irish Sea also in poor condition and placed on the Amber List.
Ms Coombes said that as UK seas warmer, the British are consuming more and more foreign fish along with the cod that we find in our supermarkets often coming from Iceland.
Ms Coombes added: ‘There are much colder waters around Iceland so it’s likely that most of the fish we eat in the UK come from there.
“What was once a truly iconic British fish, the cod, and which was the thing that was really important to us and our fisherman, is disappearing from our waters.”
But while Britons can still dine on the country’s favorite dish, Ms Coombes warned that even colder seas are now starting to depress cod populations, sparking fears for the future of cod.

She continued, âWe are starting to see populations just starting to decline in the northeast Arctic.
“It’s still at decent levels, but the decline is a concern as any species that prefers cold water like cod are endangered now that our seas are warming so it’s definitely a concern and we don’t know what it is. that’s going to happen next. “
And cod aren’t the only declining fish in British seas.
Ms Coombes also warned that squid, cuttlefish, octopus and wild Atlantic salmon were among the other species of concern to the MCS.
