Estimated Abundance of Adult Fall Chum Salmon in the Upper Yukon River, Alaska, 1997
Author: Tevis James Underwood
Publisher:
ISBN:
Category : Chum salmon
Languages : en
Pages : 48
Book Description
Presents results of a mark-recapture experiment using Darroch's two-sample, stratified model to estimate the number of fall chum salmon migrating up the Yukon River above the Tanana River from July 21-September 28, 1997. Results reaffirm conclusions drawn in 1996 that this model provides a viable means of estimating the abundance of fall chum salmon in the upper Yukon River.

Feasibility of Estimating Salmon Abundance in the Tanana River Using Sonar, 2012-2014
Author: Naomi B. Brodersen
Publisher:
ISBN:
Category : Chinook salmon
Languages : en
Pages : 111
Book Description
A study was conducted from 2012 to 2014 to assess the feasibility of using sonar, in combination with gillnetting and a fish wheel, to estimate salmon abundance in the Tanana River. Eight sites between Cosna Bluff and the confluence of the Kantishna and Tanana rivers were surveyed, bottom profiles were analyzed for suitability of sonar operation, and a site near Manley Hot Springs was selected. Split-beam sonar was operated on the left bank, and imaging sonar on the right bank. Drift and set gillnets were used to apportion the left bank sonar estimates, and drift gillnets and a fish wheel were used to apportion the right bank sonar estimates. Both sonar and test fishing methods were modified and assessed for effectiveness throughout both seasons. The sonars were found to provide effective coverage with 95% of fish passing within 80 m of the transducer on the left bank, and within 16 m on the right bank. The drift gillnets and fish wheel proved to be effective fishing methods, though refinement of these methods should be a goal in future seasons. Based on the information obtained, estimating salmon abundance in the Tanana River using sonar, with drift gillnets and a fish wheel used for species apportionment is feasible.
