Abstract: | 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. |
