Mitten Crab Watch

Smithsonian Environmental Research Center.

Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.

Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.

Using eDNA to Monitor Alaskan Waters for Invasive European Green Crabs (Dec 1, 2020)

DOC. NOAA. Fisheries.

Natural resource managers in British Columbia discovered several adult male and female European green crabs on Haida Gwaii this past July. Alarm bells immediately went off for biologists in Alaska. The archipelago of Haida Gwaii, off the coast of Prince Rupert in British Columbia, is very close to Alaska. The July discovery is the closest confirmed finding of the invasive crustacean since it was first detected in the San Francisco Bay area in 1989.
