271kg bluefin tuna the ‘biggest ever’ fish sold at Sydney Fish Markets

Sydney fish mongers have been left stunned after the “biggest ever” bluefin tuna arrived at the markets after being caught off the coast.

A giant northern bluefin tuna weighing hundreds of kilos stunned Sydney fish mongers on Tuesday, after being caught in waters of the NSW mid north coast.

The 271kg giant pacific bluefin tuna was caught off the coast of Coffs Harbour and is the “biggest ever” received at the markets in Pyrmont.

The giant fish is about four times the average size of a mature fish of its species, a spokesperson for the Sydney Fish Markets told news.com.au.

“Sydney Fish Market has confirmed the normal size range of Northern Blue Fin Tuna is between 50-60kgs,” the spokesperson said.

The fish was sold to a single retailer — iconic local seafood outlet Claudio’s Seafood.

“Now that’s a big fish,” Sydney Fish Markets wrote in a Facebook post.

“Check out this huge, 271kg Northern Bluefin Tuna spotted at the market this morning!

“This was caught by one of our suppliers, a longliner vessel working off Coffs Harbour, called Claudarah.”
