Blue sharks (Prionace glauca) are the most commonly caught species of shark globally. They are usually caught as bycatch in tuna and swordfish longlines. So how can we reduce this bycatch, whilst not impacting target tuna and swordfish catch?

Sharks have specialised electrosensory systems and can detect magnetic fields. This project investigates blue shark behavioural responses to ferrite magnets, using pelagic stereo-BRUVS (baited remote underwater video stations) and rod & line trials.
