Ten years ago off Garnea Island, large numbers of sea turtles were being trapped and drowned in commercial shrimping nets, and the sea-turtle population was rapidly declining. A law was passed requiring shrimping nets to have special flaps that enable trapped turtles to escape. Initially, compliance was strictly monitored, and sea-turtle deaths fell dramatically. In recent years, however, boats are monitored less frequently, and sea-turtle deaths have significantly increased. Clearly, therefore, compliance has decreased.
