Amoebic gill disease of turbot Scophthalmus maximus L. associated with mortalities was repeatedly diagnosed at culture facilities in NW Spain. The agent was assigned to the genus Paramoeba Schaudin, 1896. Trophozoites found in the gill tissue as well as those cultured displayed most of the principal characteristics of P. pemaquidensis Page, 1970. The identity with P. pemaquidensis, known as an agent of gill diseases of salmonids, is yet to be assessed using non-morphological criteria.
