Targeted eastern pond mussel (Ligumia nasuta) surveys in eastern Ontario / by Scott M. Reid ... [et al.].: Fs97-4/3131E-PDF

"In eastern Ontario, targeted Eastern Pondmussel (Ligumia nasuta) surveys were needed to inform provincial and federal status assessments, delineate critical habitat and support priority research and monitoring recovery actions. In 2015 and 2016, 17 inland lakes in eastern Ontario and 21 sites along the Trent River were surveyed for freshwater mussels. Collections were done using visual-tactile and clam-rake methods. A total of 5,629 live individuals representing 10 mussel species were collected; including Eastern Pondmussel and Rainbow (Villosa iris). Compared to mussel assemblages in southwestern Ontario rivers and Great Lakes coastal habitats, species richness was low. Eastern Elliptio (Elliptio complanata) was the most widespread and abundant species, accounting for more than 80% of all live individuals. Other common species were Giant Floater (Pyganodon grandis) and Fatmucket (Lampsilis siliquoidea). Eastern Pondmussel was collected from Beaver, Loughborough and White lakes and the Cataraqui River. Weathered Eastern Pondmussel shells were collected from Cranberry/Dog Lake. Zebra Mussel was detected at 10 of the 17 lakes surveyed. Across the 10 lakes, evidence of Zebra Mussel (byssal threads or attached Zebra Mussels) was observed on more than 75% of the live freshwater mussels collected. Rainbow, but not Eastern Pondmussel, was detected along the Trent River."--Abstract, p. iv.
