Amoebic gill disease (AGD) is the most significant health problem affecting the production of Atlantic salmon (Salmo salar L.) in Tasmania, Australia. AGD affects a number of cultured fish species worldwide, however its impact is insignificant when compared to that in Tasmania. The disease was first identified in southern Tasmania in 1986 shortly after the initiation of Atlantic salmon farming. AGD is a result of an endemic parasite Neoparamoeba sp. attaching to the salmon's gill tissue. Research conducted over the years has resulted in a large reduction of AGD associated mortalities. However, the disease continues to place a significant financial burden on the industry with the only effective form of treatment being freshwater baths, a strategy implemented in the late 1980's. Epidemiological studies are essential as they facilitate in identifying causal factors that may be associated with disease outbreaks. An understanding of these complex interactions is required in order to implement effective control ...
