...Stephen D. McCormick; Amy M. Regish; Arne K. Christensen; Björn Thrandur Björnsson SUMMARY Freshwater and seawater isoforms of the alpha subunit of Na + /K + -ATPase (NKA) have previously been identified in gill ionocytes of Atlantic salmon ( Salmo salar ). In the present study we examine...

...William R. Driedzic; Kathy A. Clow; Connie E. Short SUMMARY The aim of the present study was to assess whether mechanisms of glucose trafficking by red blood cells (RBCs) relate to species-specific extracellular glucose levels. Atlantic cod ( Gadus morhua ), Atlantic salmon ( Salmo salar ), cunner...

... ( Salmo salar Linnaeus), and used western blots and immunohistochemistry to characterize their size, abundance and localization. The relative molecular mass of NKA α1a is slightly less than that for NKA β1b. The abundance of gill NKA α1a was high in freshwater and became nearly undetectable after seawater...

...Daniel J. Macqueen; David Robb; Ian A.

... to interpret because the transgenic and non-transgenic fish had very different environmental/rearing histories. This study used a stable line of size-matched GH Atlantic salmon ( Salmo salar ) that were reared in a shared tank with controls (at 10°C, for∼9 months) to perform a comprehensive examination...

...Ian A. Johnston; Sujatha Manthri; Alisdair Smart; Patrick Campbell; David Nickell; Richard Alderson SUMMARY Atlantic salmon ( Salmo salar L.) were fed to satiety and reared from ∼60 g to 5000 g at ambient seawater temperatures. The effect of photoperiod manipulation on muscle growth...

...Patrick R. Wells; Alan W. Pinder ABSTRACT During development from larva to juvenile in Atlantic salmon, Salmo salar , there is a change in the anatomical potential for gas exchange among gills, body skin and yolk sac as the larvae resorb yolk, grow and develop gills. Newly hatched Atlantic salmon...

...Patrick R. Wells; Alan W. Pinder ABSTRACT During post-hatch development of Atlantic salmon ( Salmo salar L.), O 2 uptake partitioning changes from primarily cutaneous to primarily branchial. Over 80 % of post-hatch O 2 uptake was cutaneous, with the yolk sac responsible for 33 % of total O 2 uptake...
