A multi‐biomarker study on Atlantic salmon ( Salmo salar L.) affected by the emerging Red Skin Disease in the Baltic Sea
Abstract For half a decade, the Atlantic salmon in the Baltic Sea has been facing severe health issues. Clinical signs like haemorrhage, erosions and ulcerative/necrotic skin conditions in returning adults have been reported from different Swedish rivers. These primary disease signs precede a second...
