Summary, etc.: The goal of this study was to contrast the precision & cost effectiveness of alternate sampling designs using observed & simulated standing stock estimates. The study was limited to investigating within-stream spatial variability and the role of stratification in the design of juvenile standing stock surveys. The first objective was to compare differences in standing stock estimates for juvenile coho salmon & cuttthroat trout produced using several different sampling methods (such as mark-recapture, removal, and calibrated one-pass) and designs (such as simple random sampling, stratified random sampling, proportional sampling, and representative sampling). The second objective was to use the removal data in bootstrap simulations to investigate relative differences in precision and cost effectiveness of alternate sampling designs across a range of sampling intensities. The study site was located on Little Stawamus Creek, a tributary of the Stawamus River near Squamish, British Columbia.
