... ., smoltification) and following changes in environmental salinity. Smolts had higher transcript levels of CRF ligands than parr and this difference persisted following seawater transfer. Additionally, seawater transfer caused transient increases in transcription of urocortin 2 (UCN2) and CRFR2 (posterior intestine...

.... The aim of the experiment was to compare how rearing conditions affect heart morphology by coordinating a common smoltification for fish reared under simulated natural (SimNat) and simulated farmed (SimFarm) conditions. As simulated natural conditions are associated with slower growth than the simulated...

..., as it most likely recognizes both the secretory and an absorptive isoforms ( Lytle et al.,1995 ). In the case of CFTR anion channel isoforms CFTR I and CFTR II, our present findings suggest that these two isoforms are differentially regulated during salmon smoltification. The continuous increase of gill...

...Mark E. Deutschlander; Danielle K. Greaves; Theodore J. Haimberger; Craig W. Hawryshyn SUMMARY Ultraviolet visual sensitivity appears to be reduced and, possibly, lost during smoltification in anadromous populations of salmonid fishes. Similar changes occur in non-anadromous salmonids over a mass...

... of an isometric twitch and tetani. T 3 -treated fish demonstrated visible morphological changes associated with smoltification. Mean values of U crit were significantly decreased and the prolonged contraction (tetani) and twitch rates of contraction, relaxation and maximum force were significantly increased by T...

... or introduction to sea water of the salmon. Early in the smoltification process, the vitamin-A2-based visual pigment porphyropsin increased its dominance in the retinae, and radioimmunoassay of plasma indicated that T 3 levels were at a maximum prior to this increase in porphyropsin. As the parr–smolt...
