520 |a"Targeted sampling for Pugnose Minnow (Opsopoeodus emiliae), a species listed as Threatened under Canada's Species at Risk Act, was undertaken in the Canard River, Ontario during 2018. Sampling occurred in areas where Pugnose Minnow was previously detected between 2013 and 2017, as well as a 10 km, previously unfished area upstream of previous detections. Thirty-three sites (consisting of 99 hauls) were fished by depletion seining and forty-one sites (consisting of 123 trawls) were fished by pelagic trawl. A total of 19,523 fishes, representing 37 species, were captured using both gears. Abundant and frequently occurring species were Gizzard Shad (Dorosoma cepedianum), Bluegill (Lepomis macrochirus), Lepomis sp., and Emerald Shiner (Notropis atherinoides). A total of 294 Pugnose Minnow were captured (93 in seines; 201 in trawls; pooled detection at 35% of sites), representing the largest known collection of the species in Canada. Pugnose Minnow ranged in total length between 18 and 55 mm, likely representing two or more year classes. Habitat features were consistent with previous descriptions of the river and included warm, generally turbid waters mostly void of aquatic vegetation. Where aquatic vegetation occurred, emergent plants were common, especially American lotus (Nelumbo lutea), water lilies, and European common reed (Phragmites australis), with submerged wild celery (Vallisneria amercana) observed in some locations. Sampling in 2018 has increased the known range and upstream distribution of Pugnose Minnow in the Canard River approximately two-fold"--Abstract, page v.
