Book excerpt: Alaska Department of Fish and Game (ADF&G) has monitored Chinook salmon (Oncorhynchus tshawytscha) passage in the Kenai River using side-looking sonar technology from 1987 to present. The historical site at RM 8.6 used dual-beam (1987–1994), split-beam (1995–2011), and dual-frequency identification sonar or “DIDSON” (2012–2014) technology. Starting in 2013, ADF&G began operating adaptive resolution imaging sonar or “ARIS” at a new site located at RM 13.7. The RM 8.6 site was discontinued following the 2014 season in favor of data collection at the RM 13.7 site. This plan covers RM 13.7 project operations for the 2020–2022 seasons.

Download or read book Evaluation of Hydroacoustic Site on the Yukon River Near Eagle Alaska for Monitoring Passage of Salmon Across the US Canada Border 2004 written by Holly C. Carroll and published by . This book was released on 2007 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2-week study was undertaken from August 18 to August 30, 2004, to locate an appropriate site to deploy sonar for use in a long-term enumeration study of chinook salmon, Oncorhynchus tshawytscha, and fall chum salmon, O. keta, on the Yukon River near the Alaska/Canada border. Dual-Frequency Identification Sonar (DIDSONTM) and split-beam sonar equipment were tested at Calico Bluff and Six-Mile Bend, both sites within 12 miles of Eagle, Alaska. Bottom profiles were produced for the two potential sites and despite technical malfunctions with the split-beam equipment, which rendered x-y position information unusable, two suitable sonar deployment locations were found. Both split-beam and DIDSONTM systems have their strengths, and by using the DIDSONTM on a relatively steep, short cobble shore (where fish tend to be distributed inshore), and the split-beam on a long, gentle sloping bank, acoustic coverage of the river should be sufficient for fish enumeration. Six-Mile Bend was the most suitable location for a future sonar project because of its linear left-bank, stable cobble substrate, single channel and proximity to the Alaska/Canada Border. Sonar will need to be deployed on the right bank at Six-Mile Bend in future seasons. A long-term enumeration project for chinook and chum salmon near the border will provide information to help fishery managers meet conservation and management commitments made by the U.S. and Canada under the Yukon River Salmon Agreement.
