Book excerpt: During 1999 and 2000 naturally-produced and hatchery-produced chinook salmon, Oncorhynchus tshawytscha, returns to the Ninilchik River were assessed with a weir to determine the age and sex compositions of total escapements and to estimate the contribution of chinook salmon that stray to the Ninilchik River from three Kachemak Bay chinook salmon enhancement locations. Additionally during 2000, a random sample of sport harvested Chinook salmon were examined for an adipose finclip to estimate the stock composition of the harvest sampled each weekend in the Ninilchik River below the Sterling Highway.

Download or read book Ninilchik River Chinook Salmon Stock Assessment and Supplementation 2010 written by Michael D. Booz and published by . This book was released on 2016 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2010, the total number of Chinook salmon counted at the Ninilchik River weir was 658 fish, of which 623 were wild and 35 were hatchery-reared. The wild Chinook salmon escapement corresponding to the sustainable escapement goal (SEG) index monitoring period (3 July through 31 July) was 605 fish, which fell within the SEG range of 550-1,300 fish. Based on the dates of the median run times during the SEG index monitoring period, the wild Chinook salmon run was 8 days earlier than the hatchery-reared Chinook salmon run. The dominant age class was ocean age 2 for both wild and hatchery-reared Chinook salmon. No egg takes were conducted in 2010. Stocking goals were met for the Ninilchik River and all Kachemak Bay terminal saltwater fishery locations. The Ninilchik River Chinook salmon supplementation program has continued to provide sport fishing opportunities on the Ninilchik River and terminal saltwater fisheries. Continuation of Chinook salmon assessment at the Ninilchik River weir is recommended to ensure that adequate escapement of wild Chinook salmon is maintained.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report amends ROP.SF.2A.2020.04 by extending its primary objectives for an additional year. This project has 2 main goals: 1) assess the status of the Ninilchik River Chinook salmon (Oncorhynchus tshawytscha) stock, and 2) collect Chinook salmon broodstock for supplementation of the Ninilchik River and stocking of terminal saltwater fishery locations in Kachemak Bay. After the escapement goal is reviewed in 2023, Chinook salmon escapement monitoring will transition from the broodstock collection weir at RKM 7.7 to the weir at RKM 4.1. The downstream monitoring location provides full enumeration of wild and hatchery-reared escapements. After paired counts at both weir locations are made, the current SEG, associated with the upper weir, will be updated with reference to the lower weir. The resulting lower-weir goal will better reflect the whole escapement in the Ninilchik River. The complete enumeration of the hatchery-reared run and age sampling will also provide estimates of survival rates of hatchery broods and will provide harvest rates in years when the fishery prohibits retention of wild Chinook salmon. These estimates will help clarify the contribution that hatchery-reared Chinook salmon make to the Ninilchik River sport fishery.

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.
