Canadian Science Advisory Secretariat research document, 1919-5044 ; 2015/018, Central and Arctic Region "December 2015." Includes bibliographic references (p. 10-11). This research document aims to provide recommendations and to inform management decisions related to the permitting of dredging activities in the waters of Lake St. Clair, Ontario. In addition, it aims to evaluate the potential impacts of maintenance dredging activities as it relates to fish species at risk. To evaluate the impacts of maintenance dredging Fisheries and Oceans Canada (DFO) Science sampled impact sites (dredged, dredgeate) and reference sites. Impact sites were locations experiencing periodic maintenance dredging and dredgeate disposal. Reference sites were nearby locations of similar depth and substrate with no known prior disturbance from maintenance dredging activities. DFO Science conducted a repeated trawling survey to compare the fish community and fish abundance between impacted and reference sites. The impact sites were paired with nearby reference sites with similar depths and substrate type. gccst Freshwater fish gccst Endangered species gccst Habitats gccst Environmental impact Barnucz, J.
