Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal 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 ...

Risk of contamination of sturgeon species along the Lower Danube with AcIV-E virus from sturgeons raised in aquaculture systems

open access: yesIOP Conference Series: Earth and Environmental Science, 2023
Abstract It is considered that most infections caused by pathogen agents in fish species raised in the closed medium like fishing farms originate from the natural environment, thus there are few information on virus transmission from species raised in aquaculture programs to the wild ones. This issue is important taking into account that
