This project was developed to document biosecurity protocols used on affected prawn farms on the Logan River in the two growing seasons since they restarted following shut down after the 2016-17 WSD incursion. Opportunistic sampling of non-commercial crustaceans (plankton, small crustaceans) was also undertaken in northern Moreton Bay and the Logan River during April and May 2020 at a time when it was known that WSSV was active in the environment. These samples have been archived and a stop work stage of the project has been enacted upon completion of this fieldwork.
If required, the samples collected can be tested by qPCR for WSSV in order to determine if they were acting as WSSV vectors and/or reservoirs in the Logan River and northern Moreton Bay. This information would be useful to inform the design of more detailed epidemiological studies of the distribution of WSSV in the environment of SE QLD that may be undertaken in the future. Review of the biosecurity protocols the prawn aquaculture industry in the region have implemented since 2016-17 to exclude WSSV vectors from their farms will also be undertaken to determine what worked, and what didn't. This information can then be used to inform biosecurity planning for the prawn farming industry on the Logan River moving forward to identify best practice for WSSV exclusion, in order to increase their chances of successfully farming prawns in the presence of the virus and reduce risk of WSSV spillback into wild crustacean fisheries.
