Effects of Annual Thermal Regime on Growth Trajectories of Native Age‐0 Brook Trout (Salvelinus fontinalis)

Aquaculture, Fish and Fisheries
The rapidly increasing temperatures of aquatic systems associated with climate change represent a novel threat to populations of brook trout (Salvelinus fontinalis), and much uncertainty remains about the potential of these populations to acclimate ...

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 ...

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

Environmental DNA surveys can determine in-stream dominance of non-native brook charr Salvelinus fontinalis over native brown trout Salmo trutta

Ecological Indicators
For effective management of established potentially invasive species it is important to find management target sites (e.g. for depletion or eradication measures). In Sweden, the brook charr is non-native and competes with the native brown trout.

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.
