"Silver Shiner (Notropis photogenis), listed as Threatened under Canada's Species at Risk Act, is known to occur in only five drainages in Canada (Sixteen Mile Creek, Bronte Creek, Grand River, Thames River, and Saugeen River, Ontario). Fisheries and Oceans Canada conducted five targeted sampling events at six reaches in Sixteen Mile Creek: July 2016, July and September 2017, and March and August 2018. Eighty-eight sites were sampled with a bag seine to assess Silver Shiner habitat use, feeding and thermal ecology, reproduction, and life history. In total, 13,925 fishes representing 32 species were captured. Common Shiner (Luxilus cornutus) and Silver Shiner were the most abundant species captured, representing 62.7% of all fishes captured (31.5% and 31.3% respectively). 1,571 Silver Shiner were detected at 90.9% of sampled sites in 2016, 1,941 individuals were detected at 55.6% of sites in 2017, and 844 individuals were detected at 60% of sites in 2018. These results provide data to assess species ecology and will be useful for planning future sampling efforts in occupied watersheds"--Abstract, page vi.
