White Spot Syndrome Virus (WSSV) was confirmed in prawn farms on the Logan River in Moreton Bay Queensland. Subsequent investigations by Biosecurity Queensland found that low numbers of wild prawns and crabs caught in the Logan River and Northern Moreton Bay were also positive for WSSV, however recent delimitation surveys have not found the virus elsewhere in Queensland waters. The presence of WSSV in prawn farms and the environment has resulted in the establishment of biosecurity zones that restrict where some carrier species product (prawns, yabbies, worms) can be moved to, used or sold. This has had a significant impact on commercial fishers and smaller bait harvesting operations. While cooking can inactivate WSSV, it is not considered to provide an acceptable end product for the commercial bait prawn or worm markets. This investment will explore the use of gamma irradiation as an alternate treatment measure focussing on determining the minimal effective dose required to render WSSV non-infectious in prawns.
