Amoebic gill disease (AGD) of farmed Atlantic salmon (Salmo salar L)

Amoebic Gill Disease (AGD) primarily affects salmonids and was first described in marine reared coho salmon (S. kisutch) in Washington and California, USA (Kent et al., 1988) and in Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) in Tasmania (Munday et al., 1993). However, the disease has also been reported in turbot, Psetta maxima and sea bass Dicentrarchus labrax ( Munday et al., 2001) and has recently been described in ballan wrasse, Labrus bergylta (Karlsbakk et al.,  2013).
