Jellyfish wipe out salmon farm

An invasion of jellyfish has wiped out Northern Ireland’s only salmon farm, destroying more than 100,000 fish. Billions of small jellyfish, known as Mauve Stingers, flooded into the fishes’ cages in the Irish Sea, off Glenarm Bay and Cushendun. The jellyfish covered an area of about 16 square km and down to nearly 11m, which made it impossible for rescuers to reach the salmon cages. A fish farm spokesman said the attack could cost more than £1m. Managing director John Russell said he had never seen anything like this in 30 years in the business. “The sea was red with these jellyfish.”
