Ecological Research, EarlyView.Kureha Hill in Toyama Prefecture, Japan, is considered to be in nitrogen saturation, since many streams have contained high concentrations of nitrate for more than 20 years. This study verified the latest status of nitrogen saturation by comparing the latest data with 20‐year observational data.

Veterinary Research, 2023 Tetracapsuloides bryosalmonae is a malacosporean endoparasite that infects a wide range of salmonids and causes proliferative kidney disease (PKD). Brown trout serves as a carrier host whereas rainbow trout represents a dead-end host.

Computational Estimates of Binding Affinities for Estrogen Receptor Isoforms in Rainbow Trout [PDF]
arXiv, 2009 Molecular dynamics simulations were used to determine the binding affinities between between the hormone 17 beta-estradiol (E2) and different estrogen receptor (ER) isoforms in the rainbow trout, Oncorhynchus mykiss. Previous phylogenetic analysis indicates that a whole genome duplication prior to the divergence of ray-finned fish led to two distinct ...

Mink Predation of Brown Trout in a Black Hills Stream [PDF]
, 2016 In the early 2000’s, declines in the brown trout (Salmo trutta) fishery in Rapid Creek, South Dakota, caused concern for anglers and fisheries managers. We conducted a radio telemetry study in 2010 and 2011 to identify predation mortality associated with

Trophic ecology of brown trout (Salmo trutta L.) in subarctic lakes
, 2015 In subarctic lake systems, fish species like brown trout are often important predators, and their niche performance is a key characteristic for understanding trophic interactions and food web functioning at upper trophic levels.

Diseases of Aquatic Organisms, 2014 Proliferative kidney disease (PKD) caused by the myxozoan parasite Tetracapsuloides bryosalmonae is a serious parasitic disease threatening both farmed and wild salmonid populations, but very little is currently known about the distribution of the ...

Journal of Fish Diseases, EarlyView., 2023 Abstract Bacterial coldwater disease (BCWD), caused by Flavobacterium psychrophilum, results in significant losses among multiple salmonid (family Salmonidae) species. Molecular epidemiology and serotyping studies have suggested that some variants are host specific; however, these associations have not been evaluated by cross‐challenging fish species ...

Estrogenic Endocrine Disruption in Switzerland: Assessment of Fish Exposure and Effects
CHIMIA, 2008 Estrogenic exposure has been reported to occur in Swiss rivers, and there is concern that reduced reproductive health, caused by disturbances of the endocrine system, may contribute to the observed decline in brown trout catch.

The post-stocking behaviour of hatchery-reared brown troup (Salmo trutta L.) [PDF]
, 2000 Stocking, transfer and introductions of hatchery-reared salmonids are commonly used to enhance recreational or commercial fisheries and to preserve or re-establish threatened populations (Cowx, 1994).

Influence of Predation Mortality on Survival of Chinook Salmon Parr in a Lake Michigan Tributary [PDF]
, 2011 Predation mortality among Chinook salmon Oncorhynchus tshawytscha parr can act at small spatiotemporal scales and cause variability in parr survival and potential recruitment.
