With 80 percent of the world's fisheries already fully exploited or overexploited,2 illegalfishing is a serious economic and environmental threat. And the protections now in place to address it have proved inadequate.Pew's ending illegal fishing project is working around the world to develop and establish an international fisheries enforcement regime that will significantly reduce illegal, unreported, and unregulated, or IUU, fishing. This work focuses on industrial-scale fishing, which does the greatest damage both environmentally and economically, and on cooperation with key partners for policy changes and actions that can be carried out over the next five to 10years. The objective is to ensure that within a decade there is a cost-effective global system that monitors, deters, prevents, and prosecutes illegal fishing
