Title: Abundance and run timing of adult salmon in Tanada Creek in the Wrangell-St. Elias National Park and Preserve
First published: 2008
Description: "Specific objectives of this study were: 1. To use a weir to monitor annual variations in the abundance of adult sockeye and Chinook salmon in Tanada Creek and document the timing of the passage of these fish past the weir site between early June and late September; 2. to measure the entry pattern of sockeye and Chinook salmon to Tanada Creek and compare the entry pattern to the historic entry pattern data set to test for changes in annual run timing; 3. to estimate the age, sex and length of the sockeye population by sampling 10 percent of the sockeye salmon proportionate to their abundance with a minimum of 100 fish per week and a maximum of 100 fish per night; 4. to compare video estimates with weir counts to determine the effectiveness of a video tower to estimate salmon escapement in Tanada Creek; 5. to test the feasibility of sampling water quality and zooplankton to determine if variations in water quality and zooplankton biomass correlate with variations in adult sockeye salmon escapement to Tanada Lake; 6. to provide an educational opportunity for local students and residents to learn about the Tanada Creek salmon runs and how the weir counts help to provide information needed to manage subsistence fisheries on the Copper River."--P. 1-2.
