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

Journal 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 ...

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Distribution modelling for Neotropical freshwater stingrays Potamotrygon brachyura and Potamotrygon motoro (Myliobatiformes, Potamotrygonidae) in the Uruguay River basin

Journal of Fish Biology, EarlyView.
Abstract This study aimed to identify geographical distribution patterns of the giant short‐tailed river stingray Potamotrygon brachyura and the motoro stingray Potamotrygon motoro in the Uruguay River basin. Data on presence/absence of stingrays were based on fishers' knowledge accessed by interviews through expeditions in Brazil, Argentina and ...
