Amoebic Gill Disease (AGD) is one of the most serious health issues significantly increasing production costs of Atlantic salmon in Tasmania. While freshwater bathing has been used successfully to control losses, the shortage of fresh water in some salmon farming areas resulted in a quest for another treatment. Hydrogen peroxide is used overseas to control sealice infections of Atlantic salmon. Previous research suggested that it may be possible to develop a successful hydrogen peroxide treatment against AGD, reducing the reliance of the industry on fresh water.
