“…The fact that LG-1 supported the growth of a betanodavirus field isolate from Norwegian halibut indicates that gill cells from lumpfish express surface proteins that mediate nodavirus infection. In Norway, this virus has already been detected in connection with disease in farmed cod, halibut and turbot [ 30 , 46 , 47 , 48 , 49 ]. The introduction of nodavirus into lumpfish farms may be of concern, as the virus is known to cause persistent infections and disease in susceptible species.…”

“…In Norway VNN is a notifiable list 3 disease and outbreaks have been registered in farmed Atlantic halibut (Grotmol et al, 1997), turbot (Johansen et al, 2004b) and recently in farmed Atlantic cod (Hellberg et al, 2010b;Patel et al, 2007). In the period 2006-2009 there were a total of 13 and 4 outbreaks of VNN registered in Norway in farmed cod and halibut, respectively (Bornø et al, 2010;Johansen et al, 2009b).…”

“…Viral nervous necrosis (VNN) or viral encephalopathy and retinopathy (VER) disease is caused by betanodavirus (NV) in many marine fish species globally, 129 including Atlantic cod. 130 Few reports of VNN outbreaks have been reported in farmed marine finfish species such as Atlantic cod, 130,131 Atlantic halibut 132 and turbot. 133 NV infection particularly affects the larval or juvenile stages of fish, in which mortality may be very high.…”
