Moderate mortality (10 to 15%) was observed, along with anorexia and abnormal swimming behaviour, such as looping or spiral swimming and reduced coordination. Nodavirus was detected by 2 different real-time RT-PCR assays, and this was later confirmed by immunohistochemistry. This is the first report of an outbreak of VER in farmed cod in Norway, and the first report that VER affect cod exceeding 5 g in size.
