From British daily The Independent:
In a week when 6ft swordfish and porbeagle sharks have arrived off the Northumberland coast, further evidence of Britain’s warmer waters has arrived with the landing of only the third bigeye tuna to be caught off British shores.
The 40lb specimen, one of the most highly prized species of tuna, is usually found off the coasts of Hawaii and Australia where it is generally preferred to the almost indistinguishable yellowfin tuna by discriminating purveyors of sashimi and sushi.
But this one was caught by a Penzance-based fishing vessel in the Atlantic – 70-miles off Land’s End and 2,000 miles adrift of its usual habitat.
The only other known bigeye catches have been at Newlyn harbour in Cornwall, where a 15-year-old boy fished one out in 1985, and at Christchurch Bay in Dorset in 2004.
But the south-western tip of England is becoming accustomed to new arrivals.
Giant ocean sunfish were recently recorded for the first time by scientists who counted 19 of the species while conducting an aerial survey of coastal marine life in the area around Land’s End from Falmouth to Newquay.
Experts are even debating the existence of great white sharks off the Cornish coast.
A BBC documentary last weekend reported alleged sightings by a number of holidaymakers and fishermen.
The bigeye (thunnus obesus), which is commonly mistaken for the yellowfin because of the similar yellow markings on its fin, exists in tropical and subtropical waters of the Pacific, Indian and Atlantic oceans where the surface temperature exceeds 17C (62F).
The nearest areas to Britain in which it is commonly found are the Azores – though the world’s biggest suppliers are Japan, Taiwan, Spain and Korea.
