Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

Journal of Fish Biology, EarlyView.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

SharkTrack: An accurate, generalisable software for streamlining shark and ray underwater video analysis

Ecological Informatics
Elasmobranchs (sharks and rays) represent a critical component of marine ecosystems. However, they are experiencing global population declines, making effective monitoring essential for their management.

Water temperature and river discharge drive age‐dependent changes in brown trout (Salmo trutta) growth

Journal of Fish Biology, EarlyView.
Abstract Rivers and streams exhibit inherent variability in environmental conditions, particularly in water temperature and stream discharge. These factors can impact fish growth through both direct (i.e., physiological) and indirect (i.e., ecosystem productivity) mechanisms.

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

Journal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

Characterization of a novel picornavirus isolate from a diseased European eel (Anguilla anguilla) [PDF]

, 2013
A novel picornavirus was isolated from specimens of a diseased European eel (Anguilla anguilla). This virus induced a cytopathic effect in eel embryonic kidney cells and high mortality in a controlled transmission study using elvers.
