Journal of Fish Diseases, EarlyView.ABSTRACT Populations of wild brown trout (Salmo trutta) have been in long‐term decline across Central Europe, including the Czech Republic, with multiple factors, such as habitat alteration, climate change, predation and emerging diseases, implicated.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Comportement de l'espèce “Salmo trutta” dans le bassin de la Seine. Suite et fin
Knowledge and Management of Aquatic Ecosystems, 1968 Since a certain time, it is observed, in the spring, in Low Seine, that Salmonidae are coming together. These concentrations concern yearling subjects.

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT Environmental DNA (eDNA) tools are increasingly used for biodiversity monitoring, with most existing assays targeting species‐level identification. However, the use of eDNA to resolve intraspecific genetic variation remains rare and methodologically underdeveloped.

Brown Trout Abundance in Boreal Streams With Large Wood
Ecology of Freshwater Fish, Volume 35, Issue 2, April 2026.ABSTRACT Large wood has been found to be a crucial component in riverine ecosystems. However, due to the heavy channelization of rivers and intensive forestry practices over the past few decades, the amount of large wood in these ecosystems has decreased worldwide. River restoration aims to mitigate the effects of channelization and restore the channel

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 ...

Ecology and Evolution, Volume 16, Issue 3, March 2026.We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

Ecosphere, Volume 17, Issue 3, March 2026.Abstract Many populations of Atlantic salmon (Salmo salar) native to the Baltic Sea are endangered. A significant group targeting salmon in this region is the recreational trolling fishery. Due to frequent changes in fisheries regulations and conditions, both salmon conservation and fishers are affected.

Development of eNA Sampling for Early Detection of Pathogens in On‐Farm Water Sources
Environmental DNA, Volume 8, Issue 2, March/April 2026.We compare four water‐sampling methods for detecting microbial and viral eNA in livestock troughs and show all approaches effectively recover community profiles, supporting flexible, field‐ready surveillance of livestock pathogens. ABSTRACT Early detection of livestock pathogens is critical for mitigating risk and implementing timely control or ...

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...
