Book Description
In 2019, the southern offshore test fishery was conducted from July 1 to July 30 and captured 1,859 sockeye salmon representing 1,476 CPUE index points, adjusted to 1,931 CPUE postseason. The midpoint of the 2019 sockeye salmon run at the southern offshore test fishery occurred on July 21. A formal inseason estimate of the 2019 run size was made on July 26; this analysis predicted a total run to Upper Cook Inlet of 6.1 million sockeye salmon. The best-fit total run estimate deviated from the estimated total run of 5.2 million fish by 15.9%. An inseason estimate was also made for the Kenai River sockeye salmon run on July 26; the July 26 analysis predicted a total run to the Kenai River ranging between 2.2 and 4.0 million fish. A postseason analysis estimated the 2019 Kenai River total sockeye salmon run to be approximately 3.6 million fish. Finally, sockeye salmon and coho salmon genetic samples were collected and archived for future analysis.
