Hydrogen peroxide is widely used as a treatment of ectoparasite (e.g. salmon lice, amoebic gill disease) affected Atlantic salmon (Salmo salar) in aquaculture but has frequently caused unacceptable levels of mortality.

Branchial surfaces of finfish species contain a microbial layer rich in commensal bacteria which can provide protection through competitive colonization and production of antimicrobial products. Upon disturbance or compromise, pathogenic microbiota may opportunistically infiltrate this protective barrier and initiate disease.

Chloramine-T (Cl-T) is a disinfectant and sanitizer widely applied to treat bacterial infections on the gill and skin of Atlantic salmon during freshwater culture. It is typically applied as static or flush treatments during periods of disease risk or in response to pathogen detection or gross disease signs.

Reiterative freshwater bathing is the main treatment to control amoebic gill disease (AGD) of farmed Atlantic salmon in Tasmania, Australia. Regular freshwater exposure appears to control ectoparasitic cymothoid isopods, which were only seen at high prevalence and intensity in summer when fish had not been treated for over 100 days.

The marine protozoan parasite Neoparamoeba perurans has been established as the causative agent for amoebic gill disease (AGD) in Atlantic salmon (Salmo salar). Freshwater bathing is the only routinely used treatment for AGD in Australia while hydrogen peroxide (H2O2) is used in countries with cooler water temperatures.

Branchial surfaces of finfish species contain a microbial layer rich in commensal bacteria which can provide protection through competitive colonization and production of antimicrobial products. Upon disturbance or compromise, pathogenic microbiota may opportunistically infiltrate this protective barrier and initiate disease.

The present project relates principally to Programs 1 (Environment) & 2 (Industry) of the FRDC’s Strategic priority areas. Specifically the project will increase the gross value of production, profit margins, productivity and opportunity (Theme 7) for Huon, through providing the company with a means to expand operations into offshore and more exposed fish farming areas.

Cumulative data from other parasites suggests that blocking of Aquaporin channels (AQPs) may provide a suitable target for the use of pharmaceuticals to control these diseases. Neoparamoeba share many similarities with other pathogens.
