Estimates of a biologically-based spawning goal and biological benchmarks for the Canadian-origin Taku River coho stock aggregate [electronic resource] / Gottfried Pestal and Sandy Johnston. Estimations d'un objectif de frai fondé sur des données biologiques et points de référence biologiques pour l'ensemble des stocks de saumons coho d'origine canadienne de la rivière Taku Ottawa : Fisheries and Oceans Canada, 2015. ix, 114 p. : fig., graphs, maps, tables. Canadian Science Advisory Secretariat research document, 1919-5044 ; 2015/048, Pacific Region "December 2015." Includes bibliographic references (p. 40-45). This paper establishes a biological frame of reference for spawner abundances of the Coho Salmon (Oncorhynchus kisutch) stock aggregate originating in the Taku River in northwestern British Columbia. This transboundary stock aggregate is managed cooperatively by Canada and the US under the Pacific Salmon Treaty. The project focused on fitting alternative Spawner-Recruit (SR) models and estimating biological benchmarks for each model. A long time series of good-quality data are available for Taku River Coho Salmon at the aggregate level including: spawner estimates based on a consistent mark-recapture survey covering the period 1987-2013; recruitment estimates for the 1987 to 2009 brood years based on catch and escapement data and coded-wire tag recoveries in Alaskan and Canadian fisheries and surveys; and annual age and sex composition estimates. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Canada.
