If Bluefins grew bigger, they would be the main prize on the reef! They’re a strong, aggressive and beautiful-looking apex predator, and they are usually around in bigger numbers than the GTs. We can catch them up to 5 KG or more, but most are about half that size.    Sometimes, they’re spooky and moody, at other times they hammer anything you put in front of them. When the GTs are playing hard to get, it’s often Bluefin trevallies that saves the day for us.
