Genetic stock identification (GSI) is used extensively in fisheries applications and otolith isotopic composition (87Sr/86Sr) can be used to identify provenance in freshwater and anadromous species; however, each approach has inherent limitations. The potential to combine these methodologies to improve discrimination among populations has yet to be realized. In this study, GSI was combined with information from otolith 87Sr/86Sr and artificial tags (Coded Wire Tags, CWTs) to: (1) determine the stock composition of a Chinook salmon ocean terminal area fishery conducted near the mouth of the Elk River in southern Oregon, U.S.A. and resolve intractable discrimination between hatchery and naturally...</br>
