| Abstract: | Although a sport fishery for late-run Kasilof River Chinook salmon (Oncorhynchus tshawytscha) is prosecuted downstream of river kilometer (RKM) 13 and a commercial fishery occurs in nearby marine waters, the inriver abundance of late-run Kasilof River Chinook salmon has been unknown for most years. The goal of this study was to estimate the daily net upstream passage of salmon 75 cm mid eye to tail fork length (METF) or longer past RKM 13 of the Kasilof River from 15 June through 31 August 2018 using adaptive resolution imaging sonar (ARIS). Net upstream passage of Chinook salmon greater than or equal to 75 cm METF as measured by ARIS was estimated to be 3,458 (SE 166). Chinook salmon passage estimates were lower than those from a prior mark-recapture study, but run timing was similar. |
