Book Description
Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2013 at RM 8.6 using dual-frequency identification sonar (DIDSON). Estimates of midriver Chinook salmon passage between and at least 3 m from the transducers were 1,439 (SE 138) fish for the early run (16 May-30 June) and 15,185 (SE 566) fish for the late run (1 July-15 August). The early-run estimate is too small to explain weir counts at upriver tributaries. Methods and results from a second experimental sonar site located above tidal influence at RM 13.7 are presented in a separate report.

Book Description
Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2014 at RM 8.6 using dual-frequency identification sonar (DIDSON). Estimates of midriver Chinook salmon passage between and at least 3 m from the transducers were 4,862 (SE 338) fish for the early run (16 May-30 June) and 13,952 (SE 492) fish for the late run (1 July-15 August). Methods and result from a second experimental sonar site located above tidal influence at RM 13.7 are presented in a separate report.

Book Description
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.

Book Description
This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.
