Using Genetic Data to Determine Origin for Out‐Migrating Smolt and Returning Adult Steelhead Trout (Oncorhynchus mykiss) in a Southeast Alaska Drainage [PDF]

Ecology and Evolution
Oncorhynchus mykiss is a partially migratory salmonid species, and many migratory populations (known as steelhead) have declined in recent decades in the western United States and Canada.

Steelhead trout (Oncorhynchus mykiss) fed probiotic during the earliest developmental stages have enhanced growth rates and intestinal microbiome bacterial diversity [PDF]

Frontiers in Marine Science, 2022
Sustainable aquaculture practices can help meet the increasing human demand for seafood, while easing pressures on natural fish populations. Studies aimed at increasing fish production in aquaculture have included supplementary dietary probiotics that ...

Classifying and inferring behaviors using real‐time acceleration biotelemetry in reproductive steelhead trout (Oncorhynchus mykiss) [PDF]

Ecology and Evolution, 2019
Movement behaviors are central to ecology and conservation. Movement sensing technologies can monitor behaviors that are otherwise difficult to observe under field conditions and may enhance the ability to quantify behaviors at the population scale.

Quantitative genetics of migration-related traits in rainbow and steelhead trout. [PDF]

G3 (Bethesda), 2015
Abstract Rainbow trout (Oncorhynchus mykiss) exhibit remarkable life history diversity throughout their native range, and among the most evident is variation in migratory propensity. Although some populations and ecotypes will remain resident in freshwater habitats throughout their life history, others have the ability to undertake ...

Better the devil you know: sympatric fish host copes better than allopatric with a myxozoan parasite [PDF]

Frontiers in Cellular and Infection Microbiology
Ceratomyxosis due to the myxozoan parasite Ceratonova shasta affects salmonids, causing severe enteritis leading to hemorrhaging and necrosis. The waterborne parasite stages penetrate host gills and reach the fish intestine through the bloodstream ...

Age at release affects developmental physiology and sex-specific phenotypic diversity of hatchery steelhead trout (Oncorhynchus mykiss). [PDF]

PLoS ONE
Most steelhead trout hatcheries increase growth rate during rearing to produce and release yearling smolts for harvest augmentation, but natural steelhead exhibit variable age of smoltification, so this common rearing practice may not be ideal for ...

A genomic region associated with iteroparous spawning phenology is linked with age‐at‐maturity in female steelhead trout [PDF]

Evolutionary Applications
Age‐at‐maturity and iteroparity are two life history variations of steelhead trout (Oncorhynchus mykiss) that are believed to increase population resilience and stability.

Genetic divergence and one‐way gene flow influence contemporary evolution and ecology of a partially migratory fish [PDF]

Evolutionary Applications
Recent work has revealed the importance of contemporary evolution in shaping ecological outcomes. In particular, rapid evolutionary divergence between populations has been shown to impact the ecology of populations, communities, and ecosystems.

Supermarket trends for rainbow and steelhead trout products: Evidence from scanner data

Aquaculture Reports, 2023
Farm-raised trout is the second-largest foodfish sector of United States (U.S.) aquaculture, with the first trout farms established more than a century ago. Given its importance to both U.S.

Effects of dietary lipid and air replenisher on the growth and lipid deposition of steelhead trout (Oncorhynchus mykiss) confined underwater

Aquaculture Reports, 2023
In this study, we investigated the effects of dietary lipids (DL) on the growth and lipid deposition of steelhead trout (Oncorhynchus mykiss) confined underwater using various equipment.
