Book excerpt: Lower Granite Dam on the Snake River to evaluate the feasibility of using video technology to document and estimate fish ladder passage of chinook salmon Oncorhynchus tshawytscha, sockeye salmon O. nerka, and steelhead O. mykiss. A video system was to produced video images during salmon passage periods. A technician identified and counted fish images from the video record. Fish ladder passage estimates of target species made from the video record were similar to estimates made by on-site counters during daytime periods, indicating that the two methods were relatively precise. We also found that a significant percentage (6.4% and 8.3%) of target salmonids migrated during nighttime periods when on-site counts were not typically made during the two years of study. Analysis of the video record permitted verification of individual sockeye salmon identified and counted by on-site count personnel, and provided data useful to managers of this ESA-listed stock. Analysis of the video record also permitted collection of additional data such as length measurements of individual specimens, which was used to regulate a fishery located upstream.

This book was released on 1993 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field study was conducted at Lower Granite Dam on the Snake River in 1992 to evaluate the feasibility of using time-lapse video technology to document and estimate fish ladder passage of chinook salmon Oncorhynchus tshawytscha, sockeye salmon 0. nerka, and steelhead 0. mykiss using time-lapse video technology. High quality video images were produced with a time-lapse video system operating in 72 h mode from 1 May through 31 December, 1992 and fish were counted from 1 June through 15 December. From the video record we counted 15 sockeye salmon, 3,283 summer chinook salmon, 1,022 fall chinook salmon, and 125,599 steelhead. The composite count of target species generated from the video record was similar (p = 0.617) to the estimate made by on-site counters during identical time periods indicating that the two methods were precise. Comparisons of 24 h video counts and on-site (10 and 16 h) counts showed that a significant (p
