| 520 | 3 |a"We evaluated the utility of instream indexing for estimating coho escapements in a small river system for which there were independent estimates of escapement from fence counts and mark-recapture surveys. We compared three survey designs (simple random sampling, spawning ground sampling, and "index area" sampling), three sampling unit sizes (100, 200, and 400 m), and four methods of estimation (peak livecounts, peak live plus accumulated dead counts, total dead counts, and area-under-the-curve), using visual count data obtained by foot surveys. We also compared the counting efficiencies of different observers, and examined the relation between visual estimates of coho density and densities obtained by electrofishing. …"--Abstract, page iv. |
