Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

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 ...

Quantitative insights into the spatio‐temporal variation of Atlantic salmon (Salmo salar) biomass in a river catchment using eDNA metabarcoding

Journal of Fish Biology, EarlyView.
Abstract Effective species conservation and management requires comprehensive biomonitoring, enhanced by combining traditional and newer methodologies, such as environmental DNA (eDNA) analyses. A seasonal pulse of spawning adult Atlantic salmon (Salmo salar) was detected by normalised eDNA 12S reads from metabarcoding, which facilitated estimation of ...

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

Journal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

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.
