This image shows objects trailing behind a fishing boat. How does the method reduce the amount of bird bycatch by fishing boats? The color of the objects distracts the birds from the fish so the fishermen can pull in the nets. The movement of the objects in the water scares the birds away. The objects create an electrical charge that stuns the birds before they get to the fish. The objects smell like fish, which attracts the birds to them instead of the nets.
