Before this project our knowledge of the effects of husbandry on Amoebic Gill Disease (AGD) was limited. This project allowed on-farm assessment of effects of husbandry procedures and stock characteristics on AGD severity. Furthermore, we investigated the potential to re-use fresh water for...
Amoebic gill disease (AGD) is considered to be the most significant health problem for farmed Atlantic salmon in Tasmania, costing the industry an estimated $15-20 million pa. It is caused by the presence of Neoparamoeba spp. on the gills and if untreated can lead to death. Although some control of...
This project has increased our knowledge of Amoebic Gill Disease, in particular about the pathogen and the dynamics of infection. We have described a new species of neoparamoeba, Neoparamoeba perurans, and showed that it has been consistently associated with AGD worldwide. Stocking...
Megalocytiviruses are a group of closely related viruses that cause mass mortalities in both marine and freshwater aquaculture. They are of global importance as they are listed by the World Animal Health Organization (OIE). They are difficult to control as they infect over 125 fish species and...
Before this project our knowledge of immune response in Amoebic Gill Disease (AGD) was fundamentally limited and more information was required to assess the potential for immunomodulators in the management of AGD.
We confirmed that injection of bacterial DNA motif (CpG oligonucleotides) six...
The outcome of this project is the development, at the request of industry, of a proposal to enhance the genetic gains in the industry selective breeding program for AGD resistance through marker assisted selection. The confidence to proceed with such a proposal is brought about by the extensive...
Prior to this project there had been investigations into some potential candidate amoebicides, with little success except for the possibility of oxidative disinfectants such as chloramine-T. This project has since tested a number of amoebicides using a progressive approach of in vitro...
