Amoebic gill disease is caused by '''''Neoparamoeba pemaguidensis''''', the '''most important pathogenic amoeba in fish'''. The disease causes large economic losses in '''marine cultured salmonids'''.<ref> Munday, B.

More careful comparative field (e.g. susceptibility of different fish species under various environmental conditions) and laboratory studies (e.g. biochemical, molecular) using cloned isolates of the two species are required to more clearly determine the etiological agent(s) of AGD.
