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.” The Sydney Fish Markets includes six wet fish retailers, a fruit and vegetable shop and a deli. The retailers offer more than 100 different species of fish to consumers every day.
