Standardized field sampling method for monitoring the occurrence and relative abundance of the Rocky Mountain Sculpin (Cottus sp.) in Canada / by Camille J. Macnaughton, Tyana Rudolfsen, Doug A. Watkinson,... : Fs97-6/3313E-PDF

"The Species at Risk (SAR) Program’s objective for Rocky Mountain Sculpin (Cottus sp.) is to “Develop an appropriate monitoring protocol to track abundance, distribution and habitat use for the Rocky Mountain Sculpin.” In an effort to provide science information for SAR Program objectives, this report aims outlines a standardized sampling method and survey design that will document changes in the distribution and relative abundance of the Rocky Mountain Sculpin in the St. Mary and Milk river systems. We also propose guidelines for surveying the species in the Flathead River system. This report details (1) the sampling gear, (2) sampling effort required and timing, and (3) sampling sites for Rocky Mountain Sculpin abundance and range extension monitoring. This standardized sampling protocol may improve the monitoring of the species throughout its Canadian range and the assessment of population trends, allowing for a better informed management of the species over time"--Abstract.
