...Nini H. Sissener; Raul K. Suarez; Hans H. Hoppeler ABSTRACT ‘Are we what we eat?’ Yes and no. Although dietary fat affects body fat, there are many modifying mechanisms. In Atlantic salmon, there is a high level of retention of the n-3 fatty acid (FA) docosahexaenoic acid (DHA, 22:6n-3) relative...

... neurochemistry) and endocrine responses under basal and acute stress conditions for previously characterised proactive and reactive Atlantic salmon. Reactive fish showed a higher degree of the neurogenesis marker proliferating cell nuclear antigen ( pcna ) and dopamine activity under basal conditions...

...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...

...Jason S. Bystriansky; Patricia M. Schulte SUMMARY Few studies have examined changes in salmon gill ion transporter expression during the transition from seawater to freshwater, a pivotal moment in the salmonid life cycle. Seawater-acclimated Atlantic salmon were transferred to freshwater and blood...

...C. W. Hawryshyn; S. D. Ramsden; K. M. Betke; S. Sabbah SUMMARY We were interested in comparing the characteristics of polarization sensitivity in Atlantic salmon to those in Pacific salmon. Here we show that the common ancestor to the clade containing Salmo salar, Oncorhynchus mykiss, O. nerka, O...

...Junya Hiroi; Stephen D. McCormick SUMMARY We compared seawater tolerance, gill Na + /K + -ATPase and Na + /K + /2Cl – cotransporter (NKCC)abundance, and mitochondria-rich cell (MRC) morphology of three salmonids,lake trout Salvelinus namaycush , brook trout Salvelinus fontinalis and Atlantic salmon...

... 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...

...Stephen D. McCormick; J. Mark Shrimpton; Shunsuke Moriyama; Björn Thrandur Björnsson SUMMARY Atlantic salmon ( Salmo salar ) juveniles were reared under simulated conditions of normal photoperiod (LDN) or short days (LD 9:15) and ambient temperature (AMB: normal temperature increases in April...

...Ian A. Johnston; Gillian Strugnell; Marti L. McCracken; Ray Johnstone ABSTRACT Muscle development and growth were investigated in diploid populations of normal-sex-ratio and all-female Atlantic salmon ( Salmo salar L.) and their triploid counterparts produced by high-pressure treatment. Somites...

...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...

.... The present study investigated the possibility that F-type prostaglandins (PGFs) may have a pheromonal role in Atlantic salmon by measuring the olfactory sensitivity of male salmon to PGFs, the effect of waterborne PGFs on male reproductive physiology and the PGF content of mature female urine...
