Radiothyroidectomy of Larval Steelhead Trout.

open access: yesExperimental 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).

Influence of daily rhythmic light spectra and intensity changes on the growth and physiological status of juvenile steelhead trout (Oncorhynchus mykiss)

open access: yesFrontiers in Marine Science, 2023
The objective of this study was to investigate the effects of different rhythmic light spectra and intensities on growth performance and physiological and biochemical parameters of juvenile steelhead trout (Oncorhynchus mykiss).

Occurrences of Steelhead Trout (Oncorhynchus mykiss) in southern California, 1994-2018

open access: yesCalifornia 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 ...

Distinct patterns of inheritance shape life‐history traits in steelhead trout

open access: yesMolecular Ecology, 2023
AbstractLife‐history variation is the raw material of adaptation, and understanding its genetic and environmental underpinnings is key to designing effective conservation strategies. We used large‐scale genetic pedigree reconstruction of anadromous steelhead trout (Oncorhynchus mykiss) from the Russian River, CA, USA, to elucidate sex‐specific patterns

Dam trout: Genetic variability in Oncorhynchus mykiss above and below barriers in three Columbia River systems prior to restoring migrational access.

open access: yesPLoS ONE, 2018
Restoration of access to lost habitat for threatened and endangered fishes above currently impassable dams represents a major undertaking. Biological monitoring is critical to understand the dynamics and success of anadromous recolonization as, in the ...

Genome-Wide Analysis of Alternative Splicing (AS) Mechanism Provides Insights into Salinity Adaptation in the Livers of Three Euryhaline Teleosts, including Scophthalmus maximus, Cynoglossus semilaevis and Oncorhynchus mykiss

open access: yesBiology, 2022
Salinity is an important environmental factor that directly affects the survival of aquatic organisms, including fish. However, the underlying molecular mechanism of salinity adaptation at post-transcriptional regulation levels is still poorly understood

Loss of riparian forests from wildfire led to increased stream temperatures in summer, yet salmonid fish persisted

open access: yesEcosphere, 2022
Native salmonid fishes—cutthroat trout (Oncorhynchus clarkii) and steelhead/rainbow trout (Oncorhynchus mykiss)—are ecologically, culturally, and economically important species distributed across western North America. These fish are generally considered

Differential effects of two seawater transfer regimes on the hypoosmoregulatory adaptation, hormonal response, feed efficiency, and growth performance of juvenile steelhead trout

open access: yesAquaculture Reports, 2022
The differential effects of two seawater (SW) transfer regimes on the hypoosmoregulation, hormonal response, feed efficiency, and growth performance of 50 g juvenile steelhead trout (Oncorhynchus mykiss) were determined to better understand the chronic ...

Predation probabilities and functional responses: How piscivorous waterbirds respond to pulses in fish abundance

open access: yesEcosphere, 2022
How predators respond to changes in prey abundance (i.e., functional responses) is foundational to consumer–resource interactions, predator–prey dynamics, and the stability of predator–prey systems.

Genetics Reveal Long-Distance Virus Transmission Links in Pacific Salmon

open access: yesAnimals, 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 ...
