Bycatch is when fishing boats accidentally catch fish and animals that they don’t want, or shouldn’t take, like seabirds or marine creatures like sharks or turtles. Bycatch also includes young or small fish that should be left in the sea to grow.

Small-scale fishing performed with nets is one of the most common fishing methods used around the world. One of the unfortunate side effects of this method is that sea turtles, which are considered threatened, get caught in the nets along with the fish. Conservation biologists at the University of Exeter in England recently devised a way to prevent these sea turtle deaths, which they tested at a fishery in northern Peru. They found that attaching green LED lights to the nets warned the turtles away, possibly because the lights made the nets more visible. The number of sea turtle deaths was reduced, but the number of fish caught seemed to remain the same.What is the main, or central, idea of the passage?
