Restricted gene flow between resident Oncorhynchus mykiss and an admixed population of anadromous steelhead

Abstract: The species Oncorhynchus mykiss is characterized by a complex life history that presents a significant challenge for population monitoring and conservation management. Many factors contribute to genetic variation in O. mykiss populations, including sympatry among migratory phenotypes, habitat heterogeneity, hatchery introgression, and immigration (stray) rates. The relative influences of these and other factors are contingent on characteristics of the local environment. The Rock Creek subbasin in the middle Co… Show more

“…Most studies focusing on the migratory versus resident life history dichotomy have been conducted with Northern Hemisphere species including Atlantic salmon (Salmo salar; Perrier, Bourret, Kent, & Bernatchez, 2013), brown trout (Salmo trutta; Hindar, Jonsson, Ryman, & Ståhl, 1991;Meier et al, 2014), steelhead (Oncorhynchus mykiss; Matala, Allen, Narum, & Harvey, 2017;Thrower, Hard, & Joyce, 2004) and stickleback (Gasterosteus aculeatus; Drevecky, Falco, & Aguirre, 2013;Ferchaud & Hansen, 2016;Ravinet et al, 2015). Most of these model species are economically important and are classified as anadromous, a type of diadromy characterized by the return of mature or maturing individuals to their natal streams for reproduction.…”

“…For example, the high values of within basin immigration rates reported for high distances all come from large river system in the US, i.e. the Fraser river and the Columbia river (Hess et al, 2014; Bett et al, 2017; Matala et al, 2017).…”

“…However, it is important to interpret these results with caution because certain systems played a large role in driving these patterns. For example, the high wild-origin proportion of immigrants from long distance populations were mostly reported from large river systems in North America, e.g., the Fraser and Columbia rivers (Hess and Matala, 2014; Bett et al, 2017; Matala et al, 2017). Gene flow, which results from immigration and the reproductive success of immigrants, also slightly decreased with increasing distance among wild populations although the relationship was not significant (Supp.…”
