Asian carp introduced into North America pose a major threat to the ecology, environment, economy, and way of life in the Upper Midwest and Great Lakes region of the United States and Canada. The term "Asian carp" refers to a group of cyprinid fish species originally native to East Asia, which include several known to be invasive in the United States, and represent the most urgent potential danger to the ecology of the Great Lakes. The United States Department of the Interior and United States Fish and Wildlife Service presented their first annual report to Congress on the issue in December 2014.
