Book The Behavior and Ecology of Pacific Salmon and Trout

Download or read book The Behavior and Ecology of Pacific Salmon and Trout written by Thomas P. Quinn and published by UBC Press. This book was released on 2011-11-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

Book Pink Salmon Stock Status and Escapement Goals in Southeast Alaska

Download or read book Pink Salmon Stock Status and Escapement Goals in Southeast Alaska written by Andrew W. Piston and published by . This book was released on 2018 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1990s, pink salmon have been harvested in Southeast Alaska at the highest levels since record keeping began in the late 19th century. The harvest series in Southeast Alaska has exhibited odd-year dominance since 1999 and the magnitude of this cycle increased dramatically from 2006 to 2014. Even-year pink salmon harvests averaged only 22 million fish per year since 2006, primarily due to very low harvests in the Northern Southeast Inside Subregion, which have averaged only 2.5 million fish per year since 2006. Even-year harvests in the Southern Southeast Subregion quickly rebounded after a very low harvest of 3.3 million fish in 2006. The harvest of 33.2 million fish in the Southern Southeast Subregion in 2014 was the largest even-year harvest since 1996 and was approximately double the 1960?2012 average harvest for even years. Regionwide odd-year pink salmon harvests were below recent averages in 2007 and 2009 but rebounded to 59 million in 2011 and an all-time record harvest of 95 million in 2013. Pink salmon escapement indices have been consistently within or above escapement goals in the Southern Southeast and Northern Southeast Outside subregions but were below goal in the Northern Southeast Inside Subregion in four of the past five even years. We reviewed pink salmon escapement goals and recommend no changes to the three goals for pink salmon between Dixon Entrance and Cape Fairweather; however, we recommend elimination of the Situk River goal in the Yakutat area due to a lack of reliable escapement data. Twelve index streams unsuitable for consistent surveying were eliminated in the Northern Southeast Inside Subregion. At this time, no stocks of pink salmon in Southeast Alaska meet the criteria for stocks of concern as defined by the State of Alaska's Policy for Management of Sustainable Salmon Fisheries (5 AAC 39.222).

Book Pink Salmon Stock Status and Escapement Goals in Southeast Alaska Through 2019

Download or read book Pink Salmon Stock Status and Escapement Goals in Southeast Alaska Through 2019 written by Andrew W. Piston and published by . This book was released on 2020 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1990s and 2000s, pink salmon were harvested in Southeast Alaska at the highest levels since record keeping began in the late 19th century. Since 2006, the average annual harvest has dropped, largely due to poor even-year returns to the Northern Southeast Inside Subregion of Southeast Alaska, but also due to recent declines in odd-year returns. Even-year pink salmon harvests averaged only 20 million fish per year since 2006, primarily due to very low harvests in the Northern Southeast Inside Subregion, which averaged only 2.3 million fish per year during that time. Odd-year harvests to the Northern Southeast Inside Subregion remained strong through 2017, but dropped to approximately 2 million in 2019, which was the lowest odd-year harvest since the late 1970s. Even-year harvests in the Southern Southeast Subregion quickly rebounded after a very low harvest of 3.3 million fish in 2006. The harvest of 33.2 million fish in the Southern Southeast Subregion in 2014 was the largest even-year harvest since 1996 and was approximately double the 1960–2012 average harvest for even years. From 2014 to 2019, the average harvest of 12.3 million in the Southern Southeast Subregion was far below the average harvest of 27.7 million from 1985 to 2014. Pink salmon escapement indices have been consistently within or above escapement goals in the Southern Southeast and Northern Southeast Outside subregions but were below the escapement goal in the Northern Southeast Inside Subregion in four of the past five even years and in three of the past five years overall. We reviewed pink salmon escapement goals and recommend no changes. At this time, no stocks of pink salmon in Southeast Alaska meet the criteria for stocks of concern as defined by the State of Alaska’s Policy for Management of Sustainable Salmon Fisheries (5 AAC 39.222).

Book Salmonid Field Protocols Handbook

Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.
