Book excerpt: The Takotna River is a major tributary of the Kuskokwim River that currently supports modest runs of Pacific salmon, Oncorhynchus spp., compared to other tributaries in the drainage. The Takotna River weir is one of several projects operated in the Kuskokwim Area that form an integrated geographic array of escapement monitoring projects. Collectively, and in accordance with the State of Alaska's Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222), this array of projects is a tool to ensure appropriate geographic and temporal distribution of spawners, and provide a means to assess trends in escapement that should be monitored and considered in harvest management decisions. Towards this end, Takotna River weir has been operated annually since 2000 to determine daily and total salmon escapements for the target operational period of 24 June through 20 September; to estimate age, sex, and length compositions of Chinook O. tshawytscha, chum O. keta, and coho O. kisutch salmon escapement; to monitor environmental variables that influence salmon productivity; to investigate geographic distribution and length patterns of juvenile chinook and coho salmon in the Takotna River drainage; and to provide part of an integrated platform in support of other Kuskokwim Area fisheries projects.

Book excerpt: The Takotna River is a tributary of the upper Kuskokwim River that supports runs of Pacific salmon Oncorhynchus spp. A weir operated on the Takotna River is one of several projects operated in the Kuskokwim Area that form an integrated geographic array of escapement monitoring projects. Collectively, and in accordance with the State of Alaska's Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222), this array of projects is a tool to ensure appropriate geographic and temporal distribution of spawners, and provides a means to track trends in escapement that should be monitored and considered in harvest management decisions. To this end, Takotna River weir has been operated annually since 2000 to determine daily and total salmon escapements; to estimate age, sex, and length compositions of Chinook, chum, and coho salmon escapement; to monitor environmental variables that influence salmon productivity; and to serve as part of an integrated platform in support of other Kuskokwim Area fisheries projects.

Book excerpt: The Takotna River, a tributary of the Kuskokwim River, produces Chinook Oncorhynchus tshawytscha, chum O. keta, and coho salmon O. kisutch that contribute to subsistence and commercial salmon fisheries downstream of its confluence. A weir has been operated annually on the Takotna River since 2000, and is part of an array of projects used to monitor salmon escapement in the Kuskokwim River drainage. In 2009, a resistance-board weir was operated in the Takotna River from 24 June to 20 September. Salmon were enumerated by species as they migrated through the weir to determine daily and annual escapements. Samples were collected to estimate the age, sex, and length composition of escapements using a live trap.

Book excerpt: The Takotna River is a tributary of the Kuskokwim River. A weir has been operated annually on the Takotna River since 2000 to monitor returning Chinook Oncorhynchus tshawytscha, chum O. keta, and coho O. kisutch salmon. Salmon were enumerated by species as they migrated through the weir to determine daily and annual escapements. Samples were collected to estimate the age, sex, and length composition of escapements using a live trap.

Book excerpt: The Takotna River weir has operated since 2000 to estimate the abundance and age-sex-length compositions of salmon escapements, monitor environmental variables, and facilitate other Kuskokwim Area fisheries projects. In 2008, a resistance-board weir was operated in the Takotna River from 20 June through 23 September to estimate escapements of 4 species of pacific salmon Oncorhynchus spp. The Takotna River weir is one of several components that form an integrated array of escapement monitoring projects in the Kuskokwim Area. This array of projects provides a means to monitor and assess escapement trends that must be considered in harvest management decisions in accordance with the State of Alaska's Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222).

This book was released on 2005-07-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent declines in the abundance of salmon in the Arctic-Yukon-Kuskokwim (AYK) region of western Alaska have created hardships for the people and communities who depend on this resource. In 2002, the AYK Sustainable Salmon Initiative (SSI) was created to undertake research to understand the reasons for this decline and to help support sustainable management in the region. This report makes recommendations for developing the research that the AYK SSI science plan should be based on, and relates the development of a restoration plan to the results of that research.
