A new website has been launched by a consortium of partners to rapidly capture records of Chinese mitten Crab. http://mittencrabs.org.uk/
The site will help with the identification of this invasive and highly destructive species and there is a link to enable you to submit records online which will help to ensure records are quickly verified and acted upon.
The mitten crab is one of the world’s worst invasive species and as the main means of transmission is ship ballast water, it’s spread is very difficult to control. It can cause ecological and economic damage to coastal fisheries, change existing habitats, compete with native species and will even spread into fresh water habitats.
