Genetic variation in Scandinavian brown trout (Salmo trutta L.): evidence of distinct sympatric populations" (1976). Biological Sciences Faculty Publications. 347.

Whirling disease has spread rapidly throughout the United States the past 20 years, but predicting its impacts to trout populations has been problematic. Using a database that contained mark-recapture information for 384,938 trout during the years 1980-2007, a before-after control-impact study design was used to analyze data from infected river sections and non-infected reference sections on si...

the main objective of this study was to assess genetic comparison of two migratory forms of caspian trout salmo trutta caspius namely fall-run and spring-run. owing to the lack of information on its genetic differences, 5 microsatellite loci were used for 58 sample analyses. genomic dna was extracted from caudal fin using roche dna extraction kit and each pcr reaction was performed in a 25 ?l r...

Both Oncorhynchus mykiss (rainbow trout) and Salmo trutta (brown trout) have a long history of translocation and culture and a wide knowledge base exists. O.mykiss is being considered as a candidate for inland aquaculture in the salinity affected areas of southern Western Australia and this review aims, in part, at providing relevant information to those considering a trout-framing venture in W...

Sodium uptake rates were measured in wild and hatchery reared Norwegian brown trout (Salmo trutta) exposed to media of a range of pH. Sodium uptake was strongly dependent on external acidity, being reduced in media of low pH. Wild fish from the naturally acid R. Tovdal (S. Norway) were more tolerant of acid media than hatchery reared fish. The effects of increasing external sodium concentration...

Worldwide, a number of viable populations of fish are found in environments heavily contaminated with metals, including brown trout (Salmo trutta) inhabiting the River Hayle in South-West of England. This population is chronically exposed to a water-borne mixture of metals, including copper and zinc, at concentrations lethal to naïve fish. We aimed to investigate the molecular mechanisms employ...

The Caspian trout is an endangered and quite vulnerable fish, considered for a natural protection program in the southern area of the Caspian Sea. Copper oxide nanoparticles (CuO-NPs) are toxic substances, which induce oxidative stress, not to mention other pathophysiological states. The toxicity of nanoparticles on fish needs more characterization for short- and long-term effects.  Thus, the p...

Abstract We use a long time series of catch abundance from recreational fishery over 116 years to look for population trends in Atlantic salmon, and anadromous (sea trout) non-anadromous (brown) trout single catchment, Loch Lomond, west central Scotland. Year strongly predicted variation catches but effort did not meaningfully increase explained variation. Salmon showed periods increasing decre...
