An octopus ‘plague’ has left the UK shellfish industry reeling
Warming seas have increased the number of octopuses off the waters of the UK, decimating shellfish numbers and leaving fishermen floundering

When veteran fisherman Brian Tapper checked his 1,200 crab pots in waters off southwest England during this year’s crabbing season, he got a series of unwelcome surprises.
At first, in March and April, they were almost empty. Then, starting in May, they were unexpectedly packed with octopuses before sitting largely empty again over the last month or so.
The tentacled molluscs are notoriously voracious eaters, hoovering up crustaceans such as crabs and shellfish.
Tapper’s wife has already closed her dockside crab processing factory because of the diminished catch, while he doubts he can keep his side of the business afloat.
“It’s like a perfect storm for us,” Tapper said from Plymouth Harbour, where his three purpose-built crab fishing vessels are idled.
