In situ infestation of sea trout Salmo trutta with salmon louse Lepeophtheirus salmonis reveals parasite-induced behavioral modifications. [PDF]

J Fish Biol
Abstract In areas with high densities of salmon farming, spillover of the ectoparasitic salmon louse Lepeophtheirus salmonis poses a major threat to wild anadromous salmonids. By combining experimentally salmon louse infestation (mean ± standard deviation = 0.25 ± 0.25 lice g−1 fish) with acoustic telemetry, we studied the behavior of wild first‐time ...

Fast and cost-efficient species identification of Atlantic salmon (Salmo salar L.), brown trout (Salmo trutta), and their hybrids using a single SNP marker. [PDF]

J Fish Biol
Abstract A workflow for developing a cost‐ and time‐efficient, single nucleotide polymorphism (SNP)‐based assay for species and hybrid identification is described. In a reference set (n = 46), the developed assay identified individuals of two closely related species, the Atlantic salmon (Salmo salar L., n = 23) and brown trout (Salmo trutta, n = 23 ...

Application of Conservation Genomics to Investigate the Role of Pathogens on the Migration of Sea-Run Brown Trout (Salmo trutta). [PDF]

J Fish Dis
ABSTRACT Pathogens play a key role in individual function and the dynamics of wild populations, but the link between pathogens and individual performance has rarely been investigated in the wild. Migrating salmonids offer an ideal study system to investigate how infection with pathogens affects performance given that climate change and fish farming ...

Cytological studies in Salmo trutta and Salmo alpinus [PDF]

Hereditas, 2009
Ten populations of Salmo trutta and six populations of Salmo alpinus have been studied cytologically. Both species have the chromosome number 2n = 80. In Salmo trutta the number of metacentric chromosomes varies between 15 and 24 with an average mean of 20, which gives a nombre fondamental (N. F.) of 100.

Effect of polyploidization on survival of sea, brook, and rainbow trout hybrids during incubation and early feeding period [PDF]

Acta Ichthyologica et Piscatoria, 1988
Effect of polyploidization on survival of brook trout (Salvelinus fontinalis), sea trout (Salmo trutta morpha trutta) and rainbow trout (Salmo gairdneri) hybrids, including reciprocal crosses, during incubation and larval stages period was tested.

De novo assembly of the Brown trout (Salmo trutta m. fario) brain and muscle transcriptome: transcript annotation, tissue differential expression profile and SNP discovery

BMC Research Notes, 2020
Objectives The Brown trout is a salmonid species with a high commercial value in Europe. Life history and spawning behaviour include resident (Salmo trutta m. fario) and migratory (Salmo trutta m. trutta) ecotypes.

Effect of the introgression of Atlantic brown trout, Salmo trutta, into Adriatic trout, Salmo farioides in a stream at the drainage area of the Adriatic Sea basin of Montenegro [PDF]

Acta Ichthyologica et Piscatoria, 2018
Background. The diversity of wild trout stocks in Montenegro is compromised by insufficiently controlled stocking. Adriatic and Mediterranean areas show a high degree of endemism of the salmonid species, with numerous native Salmo taxa described.

The Effect of Hydrolyzed Insect Meals in Sea Trout Fingerling (Salmo trutta m. trutta) Diets on Growth Performance, Microbiota and Biochemical Blood Parameters

Animals, 2020
Simple Summary The replacement of fishmeal by environmentally sustainable alternative meals has been one of the targets in aquaculture in recent decades.
