Need

As noted in the background section, Paralytic Shellfish Toxins pose a significant economic risk to the rock lobster industry, the Tasmanian algal bloom in 2012/2013 resulted in losses to the seafood industry in the vicinity of $20million AUD and scientific data is critically needed to assist in minimising losses in future years.

Knowledge on the how rock lobsters accumulate PSTs (e.g. trophic pathway) is crucial to underpin
future management strategies, including validating the use of species which may be more readily
gathered to indicate risk (e.g. the use of farmed or wild caught mussels). Additionally, there is limited
information on the elimination of PSTs from Jasus edwardsii. This data would assist industry in an
event where large volumes of product have been harvested and are being held in live-containment
facilities, particularly in Australia where animals can be held for several weeks in tanks. Information on
persistence in the wild will also underpin decisions on potential re-direction of fishing effort to non
contaminated areas.

Objectives

1. To provide management options for industry to reduce the impacts of algal blooms. These options will potentially include: in-tank elimination conditions, testing of sentinel species to obtain early warning etc
2. To reduce technical barriers to trade for Australian rock lobsters in key markets through using the risk assessment output of the project to negotiate risk based standards.
3. To enhance R&amp
D capability on marine biotoxins and market access in Australia.
