European Green Crab

The European green crab (Carcinus maenas), has invaded fisheries in Northern California and in British Columbia, where it may compete with the much more valuable Dungeness crab. The CD it holds in its claws is a database for the USGS Pacific Coast Estuarine Information System, just one source used to compile the Atlas of Nonindigenous Marine and Estuarine Species in the North Pacific, co-written by Western Fisheries Research Center research geographer Deborah Reusser and released in 2013 by the U.S. Environmental Protection Agency in collaboration with USGS and the North Pacific Marine Science Organization (PICES).
