Amoebic gill disease (AGD)‐affected Atlantic salmon, Salmo salar L., are resistant to subsequent AGD challenge
Abstract There is inconsistent evidence of resistance of Atlantic salmon, Salmo salar L., to amoebic gill disease (AGD). Here, evidence is presented that demonstrates that Atlantic salmon exposed and subsequently challenged with AGD are more resistant than naïve control fish. Seventy‐three per cent...
