This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2016, the southern offshore test fishery (OTF) conducted from July 1 through July 29 captured 2,155 sockeye salmon Oncorhynchus nerka, which represented 1,792 catch per unit of effort (CPUE) index points. The midpoint of the 2016 sockeye salmon run at the southern OTF occurred on July 18. A formal inseason estimate of the 2016 run size was made on July 25 and this analysis predicted a total run to Upper Cook Inlet (UCI) of 6.83 million sockeye salmon. The best-fit total run estimate deviated from the estimated total run of 5.11 million fish by 33.7%. An inseason estimate was also made for the Kenai River sockeye salmon run on July 25 and this analysis predicted a total run to the Kenai River range of 3.53-5.57 million fish. Sockeye salmon and coho salmon O. kisutch genetic samples were collected and archived for future analysis.

This book was released on 2018 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2017, the southern offshore test fishery (OTF) conducted from July 1 through July 31 captured 2,586 sockeye salmon Oncorhynchus nerka, which represented 2,194 catch per unit of effort (CPUE) index points. The midpoint of the 2017 sockeye salmon run at the southern OTF occurred on July 20. A formal inseason estimate of the 2017 run size was made on July 24 and this analysis predicted a total run to Upper Cook Inlet (UCI) of 7.11 million sockeye salmon. Therefore, the first best-fit total run estimate from the formal inseason projection of the 2017 run was approximately 54.2% higher than the actual run size. An inseason estimate was also made for the Kenai River sockeye salmon run on July 24; the July 24 analysis predicted a total run to the Kenai River that range of 1.6-4.3 million fish. Sockeye salmon and coho salmon O. kisutch genetic samples were collected from the OTF and archived for future analysis.

This book was released on 2016 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2015, the southern offshore test fishery (OTF) was conducted from July 1 through July 30 and captured 2,378 sockeye salmon Oncorhynchus nerka representing 1,609 catch per unit of effort (CPUE) index points. The midpoint of the 2015 sockeye salmon run at the southern OTF occurred on 25 July. A formal inseason estimate of the 2015 run size was made on July 27; this analysis predicted a total run to Upper Cook Inlet (UCI) of 5.9 million sockeye salmon. The best-fit total run estimate deviated from the estimated total run of 6.30 million fish by 6.5%. An inseason estimate was also made for the Kenai River sockeye salmon run on July 27; the July 27 analysis predicted a total run to the Kenai River ranging between 2.20 and 3.53 million fish. The best-fit Kenai River total run estimate from this analysis (3.53 million fish) differed from the estimated total run of 3.89 million fish by 9.3%. A mixed stock analysis using genetic data (MSA) was performed on samples collected during the test fishery, which showed similar stock compositions to previous years. The MSA sampling for the OTF project was included all coho salmon O. kisutch captured to estimate spatial and temporal stock compositions of the harvest.

This book was released on 2015 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 2013 Upper Cook Inlet (UCI) commercial salmon fishing season, 2 offshore test fisheries (OTF) were conducted using drift gillnets. The southern OTF originates on the east side of Cook Inlet near Anchor Point and has been operational since 1979. Its objective is to assess the size and timing of the sockeye salmon Oncorhynchus nerka run entering UCI, including the Kenai River, during the commercial salmon fishing season. In 2013, the southern OTF occurred from 1 July through 30 July and captured 2,020 sockeye salmon representing 1,342 catch per unit of effort index points. Due to adverse weather conditions and mechanical difficulties 1 or more stations were not fished during 8 days and no fishing occurred on 3 days. Most of the missed stations occurred near the traditional peak of the sockeye salmon run. Because of the timing and relatively high number of missed stations, no formal inseason estimates of the size and timing of the 2013 sockeye salmon run were made using OTF data. A mixed stock analysis using genetic data (MSA) was performed on samples collected during the test fishery, which showed similar stock compositions to previous years. A second UCI northern test fishery, which began in 2012, was continued in 2013 to assess the potential of spatial and temporal separation of Susitna River sockeye salmon migrating through Cook Inlet using MSA. The northern OTF is located in the northern area of the Central District with the transect running across UCI from the Blanchard Line to the Drift River. In 2013, the northern OTF operated from July 1 through July 30 and captured 3,333 sockeye salmon. In 2013, the MSA sampling for both OTF projects were expanded to include all coho salmon O. kisutch captured to identify spatial and temporal stock compositions of the harvest.

This book was released on 2016 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two offshore test fisheries (OTF) operated during the 2014 Upper Cook Inlet (UCI) commercial salmon fishing season. In 2014, the southern OTF was conducted from 1 July through 1 August and captured 3,366 sockeye salmon Oncorhynchus nerka representing 2,505 catch per unit of effort (CPUE) index points. The midpoint of the 2014 sockeye salmon run at the southern OTF occurred on 16 July. Two formal inseason estimates of the 2014 run size were made on 21 and 23 July; the 23 July analysis predicted a total run to UCI of 5.8 to 9.1 million sockeye salmon. The best-fit total run estimate deviated from the actual total run of 5.28 million fish by 72%. Two inseason estimates were made for the Kenai River sockeye salmon run on 21 and 23 July; the 23 July analysis predicted a total run to the Kenai River ranging between 2.67 and 5.65 million fish. The best-fit Kenai River total run estimate from this analysis (5.65 million fish) differed from the actual total run of 3.28 million fish by 72%. A mixed stock analysis using genetic data (MSA) was performed on samples collected during the test fishery, which showed similar stock compositions to previous years. The northern OTF stations were modified in 2014 to consist of 2 transects running across UCI from the Blanchard Line to the north end of Kalgin Island and from the south end of Kalgin Island back to the Kenai Peninsula. In 2014, the northern OTF operated from July 1 through July 30 and captured 2,362 sockeye salmon. In 2014, the MSA sampling for both OTF projects was expanded to include all coho salmon O. kisutch captured to estimate spatial and temporal stock compositions of the harvest.
