A Welsh fisherman caught a giant tuna weighing 600lbs and measuring more than 8ft – but then threw it back to the sea.
David Edwards hooked the bluefin tuna, a delicacy in Japan, on Sunday off the coast of Ireland.
Mr Edwards, who now lives in the west Cork area of Ireland but is originally from the Penylan area of Cardiff , said the fish would be worth around £100,000 in Japan. And it could potentially have been worth even more after one around the size of this giant catch went for almost €3m in January .
The 58-year-old said the bluefin tuna was rare these days because it was over-fished and there are now strict controls for catching them.
The fisherman added: “It was brilliant – we know that no-one had actually managed to get one and tag it before.
“They are so powerful, they can swim up to 40mph. You have to use the boat to chase them to tire them out. They are absolutely huge.”
Mr Edwards, of West Cork Charters, caught the tuna with the help of Darren O’Sullivan and Henk Veldman as part of an ongoing catch and release programme aimed at establishing population numbers for the fish in the Atlantic.
He told the Irish Mirror : “It’s getting close to the end of the season so we were beginning to lose hope that we would see any.
“Then on Sunday we had a huge fish on the reel that must have been closer to 10ft but after two-and-a-half hours it got away.
“We knew they were out there then though and so it turned out when we managed to tag this one.”
The fish was so large that it had to be measured in the water before being tagged and released.
Mr Edwards said the rare type of tuna had also started to show up on the western coastof Wales and also off Cornwall but said the biggest ones were in the south coast of Ireland.
