Regional ecosystem responses to environmental drivers in cold‐water lakes evaluated using stable isotopes of salmonid fishes

Limnology and Oceanography, Volume 71, Issue 2, Page 1-14, February 2026.
Abstract Diverse environmental drivers influence food web energy and nutrient flows, a key ecosystem function, yet their relative importance remains poorly known. We compiled thousands of bulk stable isotope measurements (carbon and nitrogen) of brown trout (Salmo trutta, n = 2854) and Arctic charr (Salvelinus alpinus, n = 3062) from 120 cold‐water ...

Note technique : marquage des salmonidés de petite taille par ablation de l'adipeuse ou des nageoires pelviennes

Knowledge and Management of Aquatic Ecosystems, 1984
Une technique de marquage par cautérisation de la nageoire adipeuse est décrite Elle a été testée sur des salmonidés de petit taille ( 28 mm ≤ longueur totale ≤ 55 mm) pour trois espèces : omble chevalier (Salvelinus alpinus), truite fario (Salmo trutta)

Use of wild trout for PBDE assessment in freshwater environments: Review and summary of critical factors

Emerging Contaminants, 2015
Certain wild animals represent sentinels to address issues related to environmental pollution, since they can provide integrative data on both pollutant exposure and biological effects.

Coarse fish in Scotland: a threat or a resource? [PDF]

, 1993
This brief article summarizes the ecological role of non-salmonid fishes in Scottish fresh waters. Most government-sponsored research has focused on the ecologically valuable salmonids in this area, yet non-salmonid species are widely distributed in ...

Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr

Journal of Animal Ecology, Volume 95, Issue 2, Page 359-376, February 2026.
Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.

Marquage d'ombles chevalier (Salvelinus alpinus) de petite taille par injection de micromarques magnétisées

Knowledge and Management of Aquatic Ecosystems, 1987
La technique de marquage de poissons par injection, dans le cartilage nasal, de micromarques magnétisées codées est présentée. Ce type de marquage a été testé avec succès sur des ombles chevalier (Salvelinus alpinus) de très petite taille (22-55 mm ...

Population connectivity: dam migration mitigations and contemporary site fidelity in arctic char [PDF]

, 2011
BACKGROUND: Animal feeding and spawning migrations may be limited by physical barriers and behavioral interactions. Dam constructions (e.g. hydropower) commonly include gateways for fish migrations to sustain ecological connectivity.

Domestication‐Admixed Atlantic Salmon (Salmo salar) Establish a Productive Population in the Wild

Ecology Letters, Volume 29, Issue 2, February 2026.
We document colonisation of a river by highly (average 37%) domestication‐admixed salmon using genomic and phenotypic data. The resulting population now displays freshwater and marine productivity within ranges observed in wild populations. Our data demonstrate that domestication‐admixed individuals can rapidly establish populations in the wild, likely

The complete sequence of the mitochondrial genome of the Chinook salmon, Oncorhynchus tshawytscha

Biological Research, 2003
The complete sequence of the mitochondrial genome of Chinook salmon, Oncorhynchus tshawytscha, has been determined. The circular genome consisting of 16,644 base pairs encodes thirteen proteins, the 12S and 16S ribosomal RNAs, and 22 transfer RNAs. These

Occurrence and the first molecular genotyping of Dibothriocephalus dendriticus and Dibothriocephalus ditremus (Cestoda: Diphyllobothriidea) in salmonids from Iceland

Current Research in Parasitology and Vector-Borne Diseases
The occurrence of Dibothriocephalus dendriticus and Dibothriocephalus ditremus (Cestoda: Diphyllobothriidea) in salmonids from lakes Hafravatn, Thingvallavatn, Másvatn, and Ytra-Hólavatn in Iceland was studied.
