Comparative study of proliferative kidney disease in grayling Thymallus thymallus and brown trout Salmo trutta fario: an exposure experiment. [PDF]

, 2017
Proliferative kidney disease (PKD) is an emerging disease threatening wild salmonid populations, with the myxozoan parasite Tetracapsuloides bryosalmonae as the causative agent. Species differences in parasite susceptibility and disease-induced mortality

A MEASUREMENT AND COMPARISON OF DIGESTIVE ENZYMES ACTIVITY IN LARVAE OF CASPIAN BROWN TROUT AND RAINBOW TROUT AT INITIATION OF EXOGENOUS FEEDING

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2008
To determine the digestive capacity of larvae in Caspian brown trout and Rainbow trout, activity of digestive enzymes including pepsin, trypsin, chymotrypsin, a-amylase, lipase and alkaline phosphatase in 2/3 and complete yolk-sac absorption stages were

BIOMASS AND DENSITY OF BROWN AND RAINBOW TROUT IN NEW MEXICO STREAMS [PDF]

Croatian Journal of Fisheries, 1995
Mean stream numerical density of the brown trout (Salmo trutta m. fario Linnaeus, 1758) and the rainbow trout (Onchorhynchus mykiss Walbaum, 1792) was 0.090 fish/m2 of which brown trout averaged 69% (72% in total biomass) in 15 high-elevation New Mexico ...

Assessing the Predatory Effects of Invasive Brown Trout on Native Rio Grande Sucker and Rio Grande Chub in Mountain Streams of New Mexico, USA

Conservation, 2022
Invasive predators pose a critical threat to native taxa. Body size plays an important role in mediating the interactions of predator and prey. For piscivorous fishes, increased predator body size can be accompanied by the selection of increasingly ...

Stakeholders participation in conservation of brown trout stocks in Serbia [PDF]

, 2017
Native Brown Trout Salmo trutta reveal remarkable diversity in Serbia, with eight exclusive and a couple of more widely spread mtDNA haplotypes. Insufficiently controlled stocking is a main threat to that, as well as to the amenity value of wild Brown ...

Transcriptomic signatures differentiating carrier and dead-end fish hosts of proliferative kidney disease

Frontiers in Cellular and Infection Microbiology
IntroductionTetracapsuloides bryosalmonae is the causative agent of proliferative kidney disease (PKD) in salmonids. Brown trout function as a carrier host, while rainbow trout serve as a dead-end host.

SNP analyses and acoustic tagging reveal multiple origins and widespread dispersal of invasive brown trout in the Falkland Islands

Evolutionary Applications, 2021
Biological invasions are important causes of biodiversity loss, particularly in remote islands. Brown trout (Salmo trutta) have been widely introduced throughout the Southern Hemisphere, impacting endangered native fauna, particularly galaxiid fishes ...

Alternative Life-History in Native Trout (Salmo spp.) Suppresses the Invasive Effect of Alien Trout Strains Introduced Into Streams in the Western Part of the Balkans

Frontiers in Ecology and Evolution, 2020
The diversity of native trout fish Salmo spp. comprises a variety of nominal taxa in Serbia, Montenegro, and Bosnia and Herzegovina. Recent mapping of the resident trout populations detected the presence of brown trout Salmo trutta (sensu stricto) of the

Alternative Mating Strategies in Atlantic Salmon and Brown Trout [PDF]

Journal of Heredity, 2001
By screening variable number of tandem repeat (VNTR) loci, multiple paternity within clutches has been found in wild populations of southern European Atlantic salmon (Salmo salar) and brown trout (Salmo trutta). For Atlantic salmon, we determined the relative contribution of alternative male phenotypes to the next generation.
