| Abstract: | This study investigated the travel times for Russian River early-run sockeye salmon migrating from the Kenai River sonar site at river mile (RM) 13.7 to the Russian River area sport fishery at Kenai RM 73.0 and to the Russian River weir located near lower Russian Lake. A sample of 52 sockeye salmon, captured with inriver gillnets at Kenai RM 8.6, were tagged with esophageal-implant radio transmitters during 23 May to 7 July 2017. Additionally, 218 sockeye salmon were tagged with uniquely numbered spaghetti tags to investigate travel times of fish from Kenai RM 13.7 to the Russian River weir. A total of 22 radiotagged sockeye salmon migrated to the Russian River area sport fishery, taking an average of 9.8 days with a range of 5.2 days to 16.8 days. There were 3 radiotagged fish and 11 spaghetti-tagged fish that migrated past the Russian River weir, taking an average of 17.7 days (range: 13.2 days to 20.1 days) for radiotagged fish and an average of 16.9 days (range: 12.2 days to 19.4 days) for spaghetti-tagged fish. In total, the 14 tagged fish took an average of 17.1 days (range 12.2 days to 19.4 days) to travel from Kenai RM 8.6 to the Russian River weir. |
