Barramundi are an important aquaculture species with total production predicted to exceed 1000 tonnes within the next few years. Grouper culture is only just being developed but these fish are greatly sought for the live fish trade and as a result wild stocks are becoming depleted. However, outbreaks of VER in hatcheries and growout facilities can lead to catastrophic losses and the expected increases in production will not occur unless practicable and efficacious control programs are available and in place.
Striped trumpeter culture is still at the develoment stage but already an outbreak of VER has resulted in significant losses of valuable juveniles.
The disease control program needs to be acceptable to all stakeholders, especially State and Territory authorities so that uniformity in control procedures is ensured. At present differing requirements between authorities reduces their abilities to adequately control VER.
Final report
The disease strategy manual for VER reviews the relevant scientific literature on an economically important aquatic viral disease. A description of the disease with special emphasis on Australian fin fish species reveals significant disease in farmed barramundi and significant potential for disease in species such as grouper and striped trumpeter with farming potential.
The general principals of control and eradication are reviewed. Various strategies outlined in the manual will enhance the capabilities of industry and government to quickly and effectively respond to outbreaks of VER.
