IUU fishing is a global problem that threatens ocean ecosystems and sustainable fisheries. IUU products often come from fisheries lacking the strong and effective conservation and management measures to which U.S. fishermen are subject. IUU fishing most often violates conservation and management measures, such as quotas or bycatch limits, established under international agreements. By adversely impacting fisheries, marine ecosystems, food security and coastal communities around the world, IUU fishing undermines domestic and international conservation and management efforts. Furthermore, IUU fishing risks the sustainability of a multi-billion-dollar U.S. industry.
