Standardized field sampling method for monitoring the distribution and relative abundance of Plains Sucker (Pantosteus jordani) populations in Canada / by Camille J. Macnaughton, Tyana Rudolfsen, Doug...: Fs97-6/3316E-PDF

"The Species at Risk Program’s objectives for Plains Sucker (Pantosteus jordani) are to maintain current population levels throughout its Canadian range and develop a recovery strategy. In an effort to provide science information to meet the Species at Risk (SAR) Program objectives, this report aims to provide a consistent sampling method, including a survey design that informs on changes in the distribution and provides relative abundance of the Plains Sucker in the Milk River system (DU2), where it is listed as Threatened. This report details (1) the sampling gear, (2) recommended sampling effort and timing, and (3) sampling sites for Plains Sucker occurrence and relative abundance. This standardized sampling protocol should improve the monitoring of the species throughout its Canadian range, the assessment of population trends, and consequently allow for a better-informed management of the species over time"--Abstract.
