The team from the University of Exeter believed that the green light emitting diodes (LEDs) can help sea turtles spot the mesh netting and avoid it without disturbing the fish. They tested their prototype off the Peru coast in a controlled experiment.
The fishing nets not fitted with LEDs had 125 green turtles caught in the netting while the lit one only had 62. The numbers of guitarfish caught by the two nets were not affected by the illuminating add-ons.
