Background information and definitions
Acoustic and visual deterrents have been developed to cause sea turtles to flee from vessels (e.g. Lenhardt 2002) but little is known about their efficacy in practice. However, practitioners need to consider the potential for acoustic trauma resulting from sound transmissions, the habituation of target species to sounds and the potential to disturb and displace other non-target marine fauna (Schoeman et al. 2020).
