A long-term study of the impact of the invasive species Eurasian minnow Phoxinus phoxinus on brown trout Salmo trutta production in a high mountain lake, Southern Norway

Fauna Norvegica
The shallow Lake Skjerja was originally one of the most outstanding brown trout lakes on the Hardangervidda mountain plateau. During the period 1973–1985, the annual yield was on average 3.35 kg ha-1.

Validation of a new acoustic telemetry transmitter for the study of predation events in small fishes

Journal of Fish Biology, EarlyView.
Abstract Acoustic telemetry has emerged as an important tool for studying the movement and behavior of aquatic animals. Predation‐sensing acoustic transmitters combine the functions of typical acoustic transmitters with the added ability to identify the predation of tagged animals.

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

In situ infestation of sea trout Salmo trutta with salmon louse Lepeophtheirus salmonis reveals parasite‐induced behavioral modifications

Journal of Fish Biology, EarlyView.
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 ...

THE NUTRITION OF A BROWN TROUT Salmo trutta m. fario IN THE RIVER UNA [PDF]

Croatian Journal of Fisheries, 2002
An analysis of the contents of gastric–intestine system of a brown trout was made on the base of the capture 103 specimens in the aim of the description of its nutrition.

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

Journal of Fish Biology, EarlyView.
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 ...

From anecdotes to evidence: Environmental DNA detection of Arctic charr (Salvelinus alpinus L.) at the southern limit of its circumpolar range

Journal of Fish Biology, EarlyView.
Abstract The urgency of rapid species monitoring is at an all‐time high due to the increasing threat of climate change to global ecosystems, in particular freshwater habitats. Fish such as Arctic charr, Salvelinus alpinus, are particularly vulnerable to increasing water temperatures and changes in land use due to their dependence on cold waters and ...

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

Journal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...

A common garden experiment in the wild reveals heritable differences in migration tendencies among brown trout populations

Journal of Fish Biology, EarlyView.
Abstract We undertook a common garden experiment in the Burrishoole catchment, western Ireland, to test for heritable life‐history differences among neighboring brown trout (Salmo trutta L.) populations that exhibit neutral genetic divergence. Experimental crosses were made using either local females (obtained from a below‐waterfalls section of the ...
