Download or read book Unalakleet River Chinook Salmon Escapement Monitoring and Assessment, 2016 written by Jenefer Bell and published by . This book was released on 2017 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Declining run sizes and ensuing state and federal restrictions and closures to Unalakleet River Chinook salmon Oncorhynchus tshawytscha fisheries highlighted the need to obtain more complete estimates of spawning escapement. In response, multiple agencies and entities began the Unalakleet River weir in 2010 funded by United States Fish and Wildlife Service's Office of Subsistence Management. The goal was to obtain estimates of the mainstem Chinook salmon escapement and age, sex, and length (ASL) composition. An estimated 505 Chinook salmon were enumerated during the 2016 season. High water and numerous pink salmon O. gorbuscha contributed to an incomplete count of Chinook salmon in 2016, therefore the escapement estimate should be considered a minimum count and run timing could not be determined. A total of 25 ASL samples were collected but did not meet minimum sample size requirements and could not be used to estimate female percentage or age composition. Despite issues with operations in 2016, the Unalakleet River weir is an important tool for fishery managers and increased oversight and training will ensure it remains a viable option for monitoring Chinook salmon in the Unalakleet River.

The goal was to obtain estimates of the mainstem Chinook salmon escapement and age, sex, and length composition. An estimated 2,789 Chinook salmon were enumerated during the 2015 season. The central 50% of the Chinook salmon run was enumerated 7 July to 15 July in 2015. Interpolation was not needed in 2015 because there were only minor breaches that were repaired quickly. Female Chinook salmon comprised 37% of the fish sampled for age, sex, and length data and age composition of the samples was 40% age-1.3 and 35% age-1.4 Chinook salmon.

Available in PDF, EPUB and Kindle. Book excerpt: Declining run sizes and ensuing state and federal restrictions and closures to Unalakleet River Chinook salmon Oncorhynchus tshawytscha fisheries have highlighted the need to obtain more complete estimates of spawning escapement. In response, multiple agencies and entities began the Unalakleet River weir in 2010, funded by the United States Fish and Wildlife Service, Office of Subsistence Management. The goal was to obtain estimates of Chinook salmon escapement and age, sex, and length composition. An estimated 3,326 Chinook salmon were enumerated during the 2018 season. High water in June delayed the start date of the project. Therefore, there was uncertainty about whether the entire run was enumerated. Based on the shortened operational period, the central 50% of the Chinook salmon run was enumerated between July 13 and July 17. Female Chinook salmon accounted for 24.2% of the fish sampled. Age composition of the sampled Chinook salmon was 65.6% age-1.3, 19.9% age-1.2, and 13.6% age-1.4.

Available in PDF, EPUB and Kindle. Book excerpt: Declining run sizes and ensuing state and federal restrictions and closures to Unalakleet River Chinook salmon Oncorhynchus tshawytscha fisheries highlighted the need to obtain more complete estimates of spawning escapement. In response, multiple agencies and entities began the Unalakleet River weir project in 2010 funded by United States Fish and Wildlife Service's Office of Subsistence Management to obtain estimates of the mainstem Chinook salmon escapement and its age, sex, and length composition. An estimated 667 and 1,126 Chinook salmon were enumerated during the 2013 and 2014 seasons. The central 50% of the Chinook salmon run was enumerated 7 July-18 July in 2013 and could not be determined in 2014 because Chinook salmon passage was not fully evaluated. In 2013, there were 3 days of partial counts. Interpolation of missed counts could not be completed in 2014 because of incomplete information about the exact duration and extent of unmonitored periods. Age composition could not be determined from the 2013 escapement samples because the minimum sampling goal was not achieved; sex composition was 52% female. In 2014, age-1.3 Chinook salmon comprised the majority (68%) of the escapement samples.

The central 50% of the Chinook salmon run was enumerated between July 4 and July 8, which was earlier and of a shorter duration than the average run timing of all project years. Female Chinook salmon accounted for 49% of the fish sampled. Age composition of the sampled fish was 49% age-1.3 and 31% age-1.2 Chinook salmon.
