Includes bibliographical references (p. 10-12). “Fisheries and Oceans Canada surveyed the Welland River in 2014, 2015, and 2016 for freshwater mussels (Unionidae). From the 19 sites surveyed within the main channel and four tributaries (Coyle, Lyons, and Oswego creeks, and the Feeder Canal), 668 live individuals representing 11 species, including three Species at Risk (SAR), were found. Additionally, one SAR and three common species were found as valves only. Future research will benefit from quantitative sampling techniques to eliminate biases of qualitative surveys, surveying headwaters, and revisiting sites in order to better understand population trends of both SAR and common mussel species”--Abstract, p. vi.
