Bycatch can damage nets resulting in repair costs and lost time at sea. Additionally, accidental capture is threatening the conservation of turtles, sharks, and rays in Martinique and Guadeloupe. The TOPASE project is proposing innovative fishing gear to fishermen to reduce bycatch. One such gear is Pisces. This project will investigate the effect of Pisces LED lights on the bycatch of turtles, sharks, and rays.
