Isolation of salmonid alphavirus subtype 6 from wild‐caught ballan wrasse, Labrus bergylta (Ascanius)

Abstract The use of cleaner fish as a biological control for sea lice in Atlantic salmon aquaculture has increased in recent years. Wild‐caught wrasse are commonly used as cleaner fish in Europe. In Ireland, samples of wrasse from each fishing area are screened for potential pathogens prior to their...

Description
Summary:Abstract The use of cleaner fish as a biological control for sea lice in Atlantic salmon aquaculture has increased in recent years. Wild‐caught wrasse are commonly used as cleaner fish in Europe. In Ireland, samples of wrasse from each fishing area are screened for potential pathogens prior to their deployment into sea cages. Salmonid alphavirus was isolated from a pooled sample of ballan wrasse, showing no signs of disease, caught from the NW of Ireland. Partial sequencing of the E2 and nsP3 genes showed that it was closely related to the previously reported SAV subtype 6. This represents only the second isolation of this subtype and the first from a wild fish species, namely ballan wrasse.
