The federal Department of Fisheries and Oceans Canada is asking for assistance in evaluating the dispersal vectors and impacts of the European green crab, Carcinus maenas, and the Chinese mitten crab, Eriocheir sinensis. The federal Department of Fisheries and Oceans Canada is conducting assessments of the risks posed by these two crab species in Canadian waters. Part of the invasive species risk assessment process that has been adopted by DFO's Centre of Expertise in Aquatic Risk Assessment is an expert opinion survey to identify important vectors and impacts of the species, worldwide. They would appreciate your opinions on one or both of these two crab species, by taking the survey at this link:
Completing the survey should take just a few minutes of your time. DFO has recently completed biological synopses (extensive literature reviews) on green crab and mitten crab and you can access the citations and URLs for these by clicking on the survey. They will be summarizing the results of the survey in early January, and the risk assessments will be reviewed at a meeting to be held in Montreal in February.
