Occurrences of Steelhead Trout (Oncorhynchus mykiss) in southern California, 1994-2018
California Fish and Wildlife Journal, 2020 Observations of federally endangered Southern Steelhead Trout (Oncorhynchus mykiss) were compiled for the southern California Distinct Population Segment (DPS) that extends approximately 500 kilometers from the Santa Maria River (Santa Barbara County ...

Genetics Reveal Long-Distance Virus Transmission Links in Pacific Salmon
Animals, 2022 In the coastal region of Washington State, a major pathogen emergence event occurred between 2007 and 2011 in which steelhead trout (Oncorhynchus mykiss) experienced a high incidence of infection and disease outbreaks due to the rhabdovirus infectious ...

Central Valley anadromous salmonid habitat suitability criteria
California Fish and Wildlife Journal, 2023 Habitat suitability criteria (HSC) are a key information source used in designing habitat restoration projects. Many site-specific HSC have been developed in the Central Valley of California for various life stages of anadromous salmonids.

A floating bridge disrupts seaward migration and increases mortality of steelhead smolts in Hood Canal, Washington state. [PDF]
PLoS ONE, 2013 BackgroundHabitat modifications resulting from human transportation and power-generation infrastructure (e.g., roads, dams, bridges) can impede movement and alter natural migration patterns of aquatic animal populations, which may negatively affect ...

Release of hatchery adult steelhead for angler opportunity increases potential for interactions with endemic steelhead [PDF]
Ecosphere, 2018 AbstractTranslocation is often used to increase local abundance of fish and wildlife populations for conservation or harvest purposes, and effects of releases on recipient populations are context dependent. Release of non‐local animals intended for harvest can have negative demographic, genetic, and ecological risks to endemic populations when not ...

Radiothyroidectomy of Larval Steelhead Trout.
Experimental Biology and Medicine, 1965 SummaryA simplified procedure for radiothyroidectomy of large numbers of juvenile steelhead trout (alevins or fry) is described. Complete destruction of thyroid tissue was achieved 8 to 14 weeks after immersion in a solution of radioiodine in lake water (initial concentration: 12.5 or 25 μc 1-131/cc for 8 days).
