Diseases of wild and farmed Finfish

Some fish and shellfish diseases of particular significance in Scotland.

Amoebic gill disease (Neoparamoeba Perurans) is caused by the protozoan parasite Neoparamoeba perurans. It is a problem for salmonid aquaculture, resulting in severe economic losses in Tasmania and Australia and recently causing problems for the Scottish salmon industry. The parasites causes proliferative gill disease.

Clinical signs include increased mucus on the gills with white multifocal patches of swollen tissue. Fish may swim close to the surface and breathe rapidly.

The diagnostic methods include:

  • Histopathology
  • Real-Time PCR and Sequencing
