Targeted sampling for Redside Dace (Clinostomus elongatus) in Two Tree River, Ontario, 2018 / Robin C. Gáspárdy and D. Andrew R. Drake.: Fs97-13/1325E-PDF

"Targeted sampling for Redside Dace (Clinostomus elongatus), a species listed as Endangered under Canada’s Species at Risk Act, was undertaken in Two Tree River near Sault Ste. Marie, Ontario, during 2018. Because relatively little information exists about the physiological tolerances of Redside Dace, sampling was conducted to evaluate thermal requirements of the species through streamside experiments, in partnership with the University of Toronto Scarborough. The results of thermal experiments have been disseminated in the primary literature; this data report summarizes field collections of Redside Dace to undertake the experiments over the course of five sampling periods between June and October, 2018. Seining was conducted in deep pool habitat between June and September and backpack electrofishing was conducted in shallow habitats with ample in-stream cover in October. Overall, 156 Redside Dace were captured between 42 and 107 mm total length, likely representing multiple year classes. Seining (13 sampling days, 82 total hauls) resulted in the capture of 128 individuals, and backpack electrofishing (four sampling days) resulted in the capture of 28 individuals"--Abstract, page v.
