Sharks are attracted using chum, which creates a scent trail to the boat. Research suggests that this does not have an adverse effect on the natural behaviour of sharks, as long as the chum is only dispersed where the sharks are already active (following their seasonal behaviours) and the sharks are not fed. This organisation follows strict protocols to that effect and has been at the forefront of campaigns to ensure shark products are not included in chum. Chumming is used to formulate research on the great white shark, which is severely lacking to date.
