Catch-and-release fishing is seen as sustainable compared with overharvesting of fish, especially for commercially important species such as Atlantic bluefin tuna (ABFT). However, effects of this fishing on their behaviour and physiology are not fully understood. Here we show ABFTs are responding at two behavioural scales: immediately and hours post-release, with differing behavioural responses based on different capture and handling methods.
