The UK’s seas have recorded their warmest start to the year ever, driving significant shifts in marine ecosystems, BBC reported.

Warmer waters are attracting new species like bluefin tuna and jellyfish, while cold-water fish such as cod are moving further north to cooler areas.

These changes are already impacting fishing communities. Heatwaves have caused declines in cold-water species like whelks, forcing fishermen to scale back their businesses.

Scientists warn marine heatwaves will become more frequent and intense, urging both fishers and consumers to adapt to a rapidly changing marine environment, according to BBC.
