The Rapid Response Plan for Management and Control of the Chinese Mitten Crab is intended to guide efforts to mitigate the further introduction and spread of the Chinese mitten crab in the northeastern United States and Canada. Due to the unique challenges of invasive species introductions to marine and coastal ecosystems, the mitten crab and other existing and potential marine invasive species are more difficult and often more costly to manage or control than freshwater aquatic or terrestrial invasive species. This document focuses on the use of early detection and rapid response as a tool to prevent the introduction and spread of Chinese mitten crabs and other crabs belonging to the genus Eriocheir throughout northeastern United States and Atlantic Canada. The primary goal of this plan is to provide information needed to support local, state, and regional efforts to prevent and control the spread of Chinese mitten crabs throughout northeastern United States and Atlantic Canada. For more information on the development of this plan, see Early Detection and Rapid Response Plan for the Invasive Chinese Mitten Crab.

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.
