Binational Ecological Risk Assessment of Bigheaded Carps (Hypophthalmichthys spp.) for the Great Lakes Basin (Science Advisory Report - 2011/071)
Fisheries and Oceans Canada.
Bigheaded carps (Bighead and Silver carps) are considered a potential threat to the Great Lakes basin. A binational ecological risk assessment was conducted to provide scientifically defensible advice for managers and decision-makers in Canada and the U.S. This risk assessment looked at the likelihood of arrival, survival, establishment, and spread of bigheaded carps to obtain an overall probability of introduction.

Identifying Risk Factors to Strengthen Current Strategies Aimed at Minimizing the Introduction of Quagga and Zebra Mussels to Lake County, California (Jan 2009; PDF | 156 KB)
Lake County California Information Portal.
Prepared by: Lake County Fish and Wildlife Committee.
Risk assessment proposal addresses the current threat posed by both the quagga mussel (Dreissena bugensis) and zebra mussel (D. polymorpha). This report identifies a number of positive actions already undertaken by the County of Lake and encourages their continued support. Secondly, this report attempts to prioritize the various risk factors associated with each Lake County waterbody with public access, and provides organizational and management guidance to direct preventative measures against mussel introduction.
