Global Transcriptome Profiling Reveals Molecular Mechanisms of Metal Tolerance in a Chronically Exposed Wild Population of Brown Trout

open access: yesEnvironmental Science and Technology, 2013
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.

Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...

Loss of native brown trout diversity in streams of the continental Croatia

open access: yesFrontiers in Environmental Science
Introduction: The genetic diversity of brown trout in the Western Balkans has been disrupted by the introduction of non-native Atlantic phylogenetic lineages and non-native haplotypes of the Danubian phylogenetic lineage.

Modelling fishing‐induced evolution in pikeperch (Sander lucioperca) and vendace (Coregonus albula), Lake Oulujärvi, as template for ecosystem model

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fishing‐induced evolution can impact fish trait distributions, with previous studies highlighting declines in size and age at maturation. However, the effects on fish growth remain less understood, and different fishing methods may exert distinct selection pressures on populations.

COMPARATIVE RESEARCH ON LOCOMOTOR COMPONENTS OF RHEOTACTIC RESPONSE IN JUVENILE ATLANTIC SALMON (SALMO SALAR L.) AND BROWN TROUT (SALMO TRUTTA L.)

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017
We experimentally studied the locomotor components of rheotactic response in three age cohorts (0+, 1+, 2+) of Altantic salmon and brown trout parr from, respectively, the Varzuga River main channel and tributary (Kola Peninsula, White Sea drainage basin)

Genetic variation in brown trout Salmo trutta across the Danube, Rhine, and Elbe headwaters: a failure of the phylogeographic paradigm?

open access: yesBMC Evolutionary Biology, 2013
BackgroundBrown trout Salmo trutta have been described in terms of five major mtDNA lineages, four of which correspond to major ocean basins, and one, according to some authors, to a distinct taxon, marbled trout Salmo marmoratus.

Effect of heterozygosity, ploidy and incubation temperature on post‐cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The teleostean post‐cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early‐life environmental impacts on its meristic variation and if reduced heterozygosity challenges its development.

The phylogenetic position of Brown trout (Salmo trutta L. 1758) in the Jajrud River using D-Loop sequence

open access: yesیافته‌های نوین در علوم زیستی, 2016
In this study phylogenetic relationship of the Jajrud River Brown trout Salmo trutta L. 1758 in the Namak Lake basin was analyzed using complete D-Loop sequence of the mitochondrial genome, compared to other Iranian populations of the species.

Proliferative Kidney Disease in Sympatric Naturally Reproducing Populations of Rainbow and Brown Trout in Southern Peri‐Alpine Germany

open access: yesAquaculture, Fish and Fisheries
The decline of central European salmonid populations is exacerbated by global warming impacts on disease and interspecific competition. In this context, sympatric naturally reproducing populations of rainbow trout Oncorhynchus mykiss and brown trout ...
