By understanding the sensory biology of sea turtles, researchers have developed novel ways of deterring turtles from interacting with fishing gear. Bycatch reduction technologies (BRT), such as turtle excluder devices (TEDs) and ultraviolet (UV) lights, both of which are attached onto fishing nets, have been shown to be very promising in reducing the fisheries bycatch of sea turtles. Furthermore, fishing gear modifications, such as circle hooks, have also mitigated the impact of fisheries bycatch on marine turtles. Volunteers can help promote and implement some of the innovative bycatch reduction technologies and tools to save sea turtles.
