Plasma prolactin level during transfer of rainbow trout (Salmo gairdneri) and Atlantic salmon (Salmo salar) from fresh water to sea water

Uptake and Loss of Potassium by Rainbow Trout (salmo Gairdneri) in Fresh Water and Dilute Sea Water

Potassium turnover was studied in rainbow trout, Salmo gairdneri Richardson, adapted to fresh water or 22 %o sea water using K and Rb. Potassium space of the whole body increased with time and was about 5 mmol kg" after 20h, while Rb space under the same conditions was only about 0-5 mmol kg", indicating slow penetration of body K by Rb + , especially in muscle and red blood cells. Potassium in...

Atlantic salmon – Salmo salar

Distribution Th e species’ range encompasses Europe, North America, and Green land (1) (Fig.1). Non-anadromous forms occur in Europe in a few land-locked locations in Norway and Sweden, and throughout the Neva/Lake Ladoga system and Karelia regions of Russia. In North America non-anadromous forms occurred throughout most of the species’ historical range, as far west as Lake Ontario, and remain ...

Two cathelicidin genes are present in both rainbow trout (Oncorhynchus mykiss) and atlantic salmon (Salmo salar).

Further to the previous finding of the rainbow trout rtCATH_1 gene, this paper describes three more cathelicidin genes found in salmonids: two in Atlantic salmon, named asCATH_1 and asCATH_2, and one in rainbow trout, named rtCATH_2. All the three new salmonid cathelicidin genes share the common characteristics of mammalian cathelicidin genes, such as consisting of four exons and possessing a h...

Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar

There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains μ, δ and τ, respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, Atlantic salmon (Salmo salar) possess two highly similar Ig heavy chain gene complexes (A and B), comprising two μ genes, two δ genes, three intact τ genes and five τ pseu...
