Taxonomic Comments
This record represents the broad sense of Oncorhynchus henshawi that includes several subspecies that were previously considered subspecies of O. clarkii. Until a full, modern systematic revision can be completed, an interim classification of the Oncorhynchus clarkii species complex by Markle (2018) recognizes four taxa as distinct, clarkii, lewisi, henshawi, and virginalis. This treatment has been accepted by the American Fisheries Society (Page et al. 2023). Four subspecies of Oncorhynchus henshawiare recognized: henshawi, humboldtensis, seleniris, and alvordensis (Markle 2018, Peacock et al. 2018).
Ecology & Habitat

Habitat

This species inhabits a wide range of habitats from cold, high-elevation mountain streams to alkaline desert lakes. Historically, this included large, terminal, alkaline lakes (e.g., Pyramid Lake and Walker Lake); alpine lakes (e.g., Lake Tahoe and Independence Lake); slow, meandering rivers (e.g., Humboldt River); mountain rivers (e.g., Carson, Truckee, Walker, and Marys rivers); and small headwater tributary streams (e.g., Donner and Prosser Creeks) (USFWS 2008). Populations in the western Lahontan Basin are found in the lakes and high-elevation alpine habitat while populations in the eastern and northwestern Lahontan Basin generally occur in low elevation rivers with one small terminal lake (Peacock et al. 2018).
