Tagged bluefin tuna dives to 544 m
INSTITUTE for Marine and Antarctic Studies researchers caught and tagged a 17 kg southern bluefin tuna off Portland, Victoria, in 2014.
According to a recent post on the Tuna Champions Facebook page, the small but feisty SBT was caught with a skirted single J hook lure. It put up a 15-minute fight and took off as soon as it was back in the water after tagging.
It then cruised around off Portland before weaving its way towards Port MacDonnell SA, sometimes diving to incredible depths of 544 metres. Its tag popped off after 41 days.
