Turtle power: Rehabilitated loggerheads released back into the sea

Two loggerhead turtles washed up on the UK coast this winter have been flown to Gran Canaria and released back into the sea.

The two animals - Dink and James - were the only survivors of 23 turtles washed up on the British and Irish coast this year - a record number.

The pair were nursed back to health at the Blue Reef Aquarium in Newquay, Cornwall, during six months of rehabilitation.

Following their recovery they have now been returned to the sea off a beach in Las Palmas, Gran Canaria.

They flew to Las Palmas on Monday June 23 and were released on a beach two days later with their keepers watching on.

Both turtles have been microchipped and if they are spotted again by fishermen or on the beach a tag in their flipper can be used for identification.

Releasing the pair, Blue Reef curator Matt Slater told them: "Hopefully, we won't be seeing you again. Have many, many years of swimming in the ocean." He added: "It was absolutely beautiful. Let's hope no more turtles get stranded, but if they do we know we can look after them.

"I hope they will be OK. In their lifetime, things will change a lot. The future for turtles in general is not great." After arriving in Gran Canaria, Dink and James were checked over and given the all-clear at the Wildlife Recovery Centre of Tafira.

Pascual Calabuig (corr), the centre's director, said: "Seventy-five percent of the sea turtles that we receive have been hurt because of man's activities.

"We see turtles damaged by hooks, nets, pollution, oil and plastic bags. Turtles damaged by boats are the worst to recover.

"We try to patch up their shells with fibreglass, but survival rates are low." Loggerheads turtles - real name carettta caretta - are categorised as endangered and are threatened by industrial fisheries, habitat loss and climate change.

James was stranded on Blackrock Beach, Bude, on January 26, and Dink a week later further up the coast at Putsborough Beach, Woolacombe, Devon.

Mr Slater said: "They were both in a poor state when they arrived. James was particularly bad. It was touch and go for a while.

"Being a larger, more powerful turtle, James is thought to have battled the strong currents, which left him exhausted.

"Dink, being younger, probably endured less stress as he just drifted on the current and arrived inland faster." James was suffering from pneumonia, dehydration and a lung infection when he arrived and both turtles had hypothermia.

They were warmed up slowly and the water temperature of their rehabilitation tanks was increased from 10C to 25C.

Mr Slater said: "James was put on a course of antibiotics and anti-fungals to cure infection. When he first took food by himself, after two weeks of tube feeding, we knew he was on the road to recovery." Loggerheads breed on the beaches of the Mediterranean, West Africa, Brazil and the south-east coasts of the US and Florida has the largest population.

They travel around the large ocean currents in a wide loop and from nesting beaches in Florida, follow the Gulf Stream across the Atlantic to Madeira, and then head south to the Canary Islands and Cape Verde Isles, before heading back to the south-east coast of the US.

Peter Richardson, of the Marine Conservation Society, said: "We are not 100 per cent sure how turtles navigate this route.

"They have some geo-magnetic understanding, for broad-scale navigation, and can use chemical cues coming off of islands, such as windblown dust, as a homing device." Scientists are uncertain why loggerhead turtles have been stranding on UK and Irish coasts in record numbers this year but experts say extreme weather systems may be a cause.

Mr Richardson added: "From December to February we had strong and persistent south-westerly winds towards UK shores. Small or compromised turtles in the north-east Atlantic may have drifted off-course because of this.

"Juvenile jellyfish are opportunistic feeders. The jellyfish may have attracted them off their normal course. Then they may have got caught in a weather system and blown over. At 15C (59F) the turtles stop feeding and at 10C (50F) they shut down."

I hope they make it.
