Standardized field sampling method for monitoring the distribution and relative abundance of the stonecat (Noturus flavus) Missouri population in Canada / by Camille J. Macnaughton, Doug A. Watkinson,... : Fs97-6/3355E-PDF

"Stonecat is common in many areas of Canada, but it is extremely rare within Alberta and Saskatchewan, where it is the only catfish species native to Alberta and listed as Threatened. To provide Science Advice to future status and population assessments of Stonecat, this report aims to provide a consistent sampling method and survey design to inform on changes in the distribution and relative abundance of Stonecat populations in the Missouri watershed in Alberta and Saskatchewan. This report details (1) the sampling gear, (2) recommended sampling effort and timing, and (3) sampling sites for Stonecat occurrence and abundance. This standardized sampling protocol is intended to improve the monitoring of the species, the assessment of population trends, and consequently allow for a long-term monitoring of the species in the Missouri watershed in Alberta and Saskatchewan"--Abstract, page vii.
