Proceedings of the CSAS Peer-review of the Risk Assessment for New Zealand Mud Snail in Canadian Waters; 24-25 March, 2010

Chairperson: N.E. Mandrak
Editors: M.A. Frey and T.W. Therriault


The New Zealand mud snail (Potamopyrgus antipodarum) was reported in the Great Lakes in 1991 and, more recently, was identified on the west coast of Canada in 2006. Fisheries and Oceans Canada (DFO) conducted a national risk assessment to determine the potential biological risks posed by this non-indigenous species to Canadian coastal and inland waters. A draft research document, outlining the background, methods, results, conclusions and recommendations of the risk assessment, was developed by DFO Science (Therriault et al. 2010) and subsequently peer reviewed by experts at a workshop held in Ottawa, Ontario, March 2010. This document summarizes the Proceedings of that workshop.
