Yukon River Chinook Salmon Subsistnce Harvest ASL and Genetic Stock Identification, 2018

ISBN:

Languages : en
Pages : 30
Book Description
Understanding the age, sex, length, and stock of origin of Chinook salmon Oncorhynchus tshawytscha, caught in subsistence fisheries of the Yukon River is important for making well informed management decisions and forecasting salmon runs. The objective of this study was to collect representative genetic mixed stock analysis information, coupled with age, sex, and length data, from the Chinook salmon subsistence harvest in the Coastal District and Districts 1–5. A total of 43 subsistence fishermen from 13 communities sampled 1,573 Chinook salmon that were harvested using gillnets, fish wheels, and dip nets. The age, sex, and length composition of the harvest was 0.3% age-3, 16.9% age-4, 47.1% age-5, 33.9% age-6, 1.8% age-7, 32.5% female, and an average of 725 mm in length. The proportion of the catch that was Canadian-origin ranged from 0.38 in District 2 to 0.72 in District 5. The data generated from this project are essential to estimate total run size of Yukon River Chinook salmon stocks, evaluate boarder passage and harvest share agreements as defined in the Pacific Salmon Treaty, and update spawner-recruit models used to estimate past and future run productivity. Due to the variability in Chinook salmon runs, management actions, and harvest, annual monitoring of the subsistence Chinook salmon harvest is needed.

Pages : 27
Book Description
Reports on estimations of the stock composition of all harvests and test fishery catches of Chinook salmon, Oncorhynchus tshawytscha, within the Yukon River drainage in 2010. Stock composition was estimated for 3 geographically-based stock groups termed Lower, Middle, and Upper, and commercial and subsistence harvest age compositions were estimated from aged scales collected. Age compositions from sampled fish, in combination with genetic stock estimates, were used to estimate the stock composition for each age class. Also includes historical data from 1981-2009.
