| Abstract: | Adaptive resolution imaging sonars (ARIS) are used to produce inriver abundance estimates of Kenai River early- and late-run Chinook salmon Onchorhynchus tshawytscha and Kasilof River late-run Chinook salmon. These sonars can be used to produce inseason estimates of fish 75 cm mid eye to tail fork length (METF) or longer, and when used over the entire run, can be used in conjunction with test fish data to produce postseason abundance estimates of all Chinook salmon regardless of size. Sonar estimates of Chinook salmon inriver passage provide the basis for estimating spawning escapement and implementing management plans that regulate harvest in the competing fisheries for these stocks. |
