National Snapper Workshop - Rebuilding our iconic Snapper stocks
There are numerous Australian jurisdictions that have faced and are currently facing management challenges with Snapper stocks in decline. It proposed that a national Snapper workshop is needed to bring together from each jurisdiction fisheries managers, scientists and key stakeholders from the commercial and recreational fishing sectors to:
(1) Communicate findings on Snapper research, gain an insight into the challenges, successes and learnings from management arrangements implemented in each jurisdiction.
(2) Identify a national approach to collaborate and manage a Snapper stock that crosses jurisdictional boundaries
(3) Develop a set of national R&D priorities for Snapper, in particular dealing with the issue of ‘hyperstability’.
(4) Develop a tool kit to support fisheries managers recover Snapper stocks.
The main aim of the workshop is for each jurisdiction to exchange information on Snapper and to ensure that Snapper R&D has a national co-ordinated approach that addresses the challenges being faced, makes the most efficient use of available resources and integrates key stakeholders such as the recreational and commercial fisheries, government and research providers.
Final report
- identify key issues and challenges for Snapper, review Snapper research and critique jurisdictional management arrangements;
- explore a national approach to collaborate and manage cross-jurisdictional Snapper stocks;
- explore and develop a set of national R&D priorities for Snapper that address the challenges being faced; and,
- develop a tool kit to support fishery managers to recover depleted Snapper stocks
Improving early detection surveillance and emergency disease response to Pacific Oyster Mortality Syndrome (POMS) using a hydrodynamic model for dispersion of OsHV-1
Pacific Oyster Mortality Syndrome (POMS) is a disease caused by Ostreid Herpesvirus type 1 (OsHV-1) microvariant, which causes rapid high mortalities (up to 100%) in Pacific oysters. POMS has caused significant economic impacts to the oyster growing industry in parts of NSW and Tasmania where it occurs. On 28 February 2018 OsHV-1 was first detected in Port Adelaide River feral oyster populations. PIRSA and industry mounted an immediate emergency response aimed at containing the virus to the Port and preventing spread to the nearby oyster industry (>25km away).
In the absence of accurate information, surveillance designs and emergency response plans (including translocation protocols) assume a disease spread distance of 5NM (10km) to define epidemiological units for all water bodies (see Figure 1). That uncertainty causes policy makers to take a conservative approach. Consequently there is a need to improve the accuracy of predictive information used to manage such aquatic disease incursions.
Aim: Model the dispersal of Ostreid herpesvirus (OsHV-1) particles from various locations around South Australia to determine epidemiological units aimed at improving surveillance, biosecurity zoning and future emergency responses.
This project aligns with two key objectives of Australia’s National Strategic Plan for Aquatic Animal Health (AQUAPLAN 2014-2019): (1) Enhance surveillance, and (2) Strengthen emergency disease preparedness and response capability. See http://www.agriculture.gov.au/animal/aquatic/aquaplan.
A recent FRDC project (2006/005) demonstrated how various oceanographic data can be incorporated into a hydrodynamic model (e-SA marine system) to map past, present and future ocean conditions. This project proposal will provide a case study for how such a model can predict pathogen spread to underpin improved surveillance designs, effective emergency disease response and appropriate biosecurity zoning for translocation protocols.
