Cytogenetic and histological studies of the brook trout (Salvelinus fontinalis) x arctic charr (Salvelinus alpinus) hybrids [PDF]

, 2012
In aquaculture, application of fish hybrids has increased. This technique permits improvement of the fish production by providing specimens showing better growth rate when compared to the parental species.

Seasonal Variation of δ13C and δ15N in a Boreal Lake Fish Community—Year‐Round Patterns and Explanatory Variables

Ecology of Freshwater Fish, Volume 35, Issue 2, April 2026.
ABSTRACT Seasonal changes in freshwater ecosystems influence fish resource use through both environmental and biological factors, but year‐round studies that include ice‐covered months have been lacking. We investigated seasonal variation in the stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) using year‐round monthly sampling of the fish ...

Feeding selectivity of brown trout (Salmo trutta) in Loch Ness, Scotland [PDF]

, 2000
The aim of this study was to compare statistically the zooplankton assemblage ingested by brown trout (Salmo trutta) in Loch Ness with that of the zooplankton in the water column.

Differentiation at the MHCIIα and Cath2 Loci in Sympatric Salvelinus alpinus Resource Morphs in Lake Thingvallavatn [PDF]

, 2013
Publisher's versionNorthern freshwater fish may be suitable for the genetic dissection of ecological traits because they invaded new habitats after the last ice age (∼10.000 years ago).

Environmental DNA‐based RPA‐CRISPR/Cas12a assay for on‐site detection of chironomid larvae in aquatic environments

Pest Management Science, Volume 82, Issue 3, Page 2458-2467, March 2026.
An environmental DNA (eDNA)‐based recombinase polymerase amplification (RPA)‐CRISPR/Cas12a assay enables rapid, specific, and on‐site detection of chironomids, supporting early warning, and ecological monitoring in freshwater environments. Abstract BACKGROUND Freshwater chironomid midges pose a significant threat to drinking water quality and ...

Rapid and biased evolution of canalization during adaptive divergence revealed by dominance in gene expression variability during Arctic charr early development

Communications Biology, 2023
Adaptive evolution may be influenced by canalization, the buffering of developmental processes from environmental and genetic perturbations, but how this occurs is poorly understood.

Preferencia alimenticia y eficiencia en el consumo de alimento en la especie de pez Savelinus Alpinus (Salmonidae : Salmoniforme) [PDF]

, 2008
The fish Salvelinus alpinus (L.) exhibits a high phenotypic plasticity and it frequently forms subgroups that differ in their behaviour, feeding apparatuses, and foraging efficiency.

Integrating Lab‐ and Field‐Based Approaches to Decipher Individuals' Response to Anthropogenic Change

Ecology Letters, Volume 29, Issue 3, March 2026.
We integrate laboratory assays and GPS tracking to examine consistent risk‐taking behaviour in Fan‐tailed Ravens (Corvus rhipidurus) inhabiting Israel's Dead Sea coastline. Individual risk profiles were consistent across lab and field contexts, with risk‐prone birds remaining near tourist sites and risk‐averse birds ranging farther into natural ...

Viral Disease Histopathology in Aquaculture Finfish: Organ‐Specific Pathological Changes and Diagnostic Insights, Referencing the World Organisation for Animal Health: A Review

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT The aquaculture industry faces significant challenges from viral diseases, many of which are listed by the World Organisation for Animal Health (WOAH) as priority pathogens due to their impact on global finfish health and production. This review synthesizes current knowledge on the histopathology of key WOAH‐listed viral pathogens, including ...
