Weighing in at just over two pounds this chunk of tuna is a mere chip off the old block, but it has already made culinary history.

Carved from the largest Bluefin tuna ever to have been caught in Scottish waters, it was transported to Glasgow from Harris in the Outer Hebrides and transformed into the first-ever dish of Scottish tuna sushi.

The first person to taste the raw fish delicacy was Angus Campbell, the skipper who landed the nine-foot 515lb Bluefin tuna on his boat, the Orca 3, ten miles west of Leverburgh.

Speaking in his native Gaelic, he said "math ga riobhadh!" meaning "wow!" and described the fish as "soft, rich, and delicious".

Mr Campbell had been contacted by Perthshire chef Ross Brown, owner of Lov- Sushi, when news of the catch broke, to ask if he could experience the difference between Bluefin tuna and the more common Yellowfin, which Mr Brown normally sources through his Perthshire supplier.

Stocks of Pacific Bluefin tuna have declined due to increased demand for its richly flavoured deep red meat, and it has been endangered for several years.

Earlier this year, a 489lb specimen caught off northeastern Japan sold for a record £1.09 million - which means just a bite of Mr Campbell's fish could have fetched over £100.

Atlantic Bluefin tuna are becoming increasingly common in Scottish waters Scotland due to rising sea temperatures.

Mr Campbell has already caught two 400lb Bluefins this year, but threw them back. He kept this one because it had swallowed the hook and it had gone too far down its throat to save it.

Unfortunately for him, while it's not illegal to land the tuna - it is illegal to sell it.

However, Mr Campbell gave it away to friends and family on Harris.
