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 ...

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 ...

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 ...

The story of a small trout fishery [PDF]

, 1993
This article relates the experience of creating and developing a fishery in southern England. The fishery was made from a small stream which dries up from time to time, and marks the boundary between a Sussex farm and a large coniferous forest.

Bull trout (Salvelinus confluentus) exhibit binge‐feeding and digestive flexibility during seasonal resource pulses associated with salmon migrations

Journal of Fish Biology, EarlyView.
Abstract Resource pulses are infrequent, ephemeral events of resource hyperabundance that can represent important feeding opportunities for consumers. To capitalize on pulsed resources, consumers can exhibit behavioural and physiological traits including binge‐feeding and phenotypic plasticity of digestive physiology, although expression of these ...

Central area redd project [Ribble, Hodder and Lune catchments] [PDF]

, 2000
Redd counting is an integral part of most Fishery Officers duties. The number and distribution of salmonid redds throughout salmonid catchments provides invaluable information on the range and extent of spawning by both salmon and sea trout.
