Island shark tag found off Canada

A basking shark tagged off the Isle of Man has provided vital clues on the species' migration habits after its tag was recovered off the Canadian coast.

The creature, an 8m-long mature female, was one of three electronically tagged in Manx waters last summer.

The 3,000 tag, which is programmed to detach itself after a certain amount of time, came off near Newfoundland.

Data collected from the device revealed the shark swam almost 10,000km at depths of up to 1.3km.

'Amazing result'

Jackie Hall, coordinator for Manx Basking Shark Watch, said: "This is a truly amazing result.

"Previous studies indicated that our Manx basking sharks are part of an annual migration centred around the British and French coasts.

"Although scientists knew that basking sharks occur worldwide in temperate waters off Canada and New Zealand, this is the first tagging work to indicate that the Atlantic basking shark population is one unit."

It emphasises the need for us to collaborate with scientists and governments internationally to protect basking sharks

Dr Fiona Gell, Fisheries and Wildlife Officer for the Manx Department of Agriculture Fisheries and Forestry, added: "This has exciting implications for our role in the international conservation of this endangered species.

"It emphasises the need for us to collaborate with scientists and governments internationally to protect basking sharks."

One of the other tags attached to a basking shark in the Isle of Man last year was recovered in mudflats on the west coast of Scotland.

The harmless plankton-feeding creatures, which are the second biggest fish in the world, are frequently spotted off the British Isles between May and September.

According to the Manx Wildlife Trust a record number of sightings of the creatures were reported in Manx waters last year - a total of 742.
