Seafood CRC: Extending biotoxin capability and research in Australia through development of an experimental biotoxin contamination facility to target industry relevant issues

A short-term experimental biotoxin contamination facility was set up at Roseworthy, South Australia, to examine the uptake and depuration of marine biotoxins from one of the most toxic dinoflagellates known, Alexandrium catenella. Over the period of one year, SARDI’s Seafood Food Safety group...

Field trials to experimentally test if alternative sea lion excluder devices (SLEDs) adequately prevent Australian sea lions from entering rock lobster pots

This project tested the efficacy of two new sea lion excluder devices (SLEDs) in preventing entry of seals into southern rock lobster (Jasus edwardsii) pots designed by fishers from the South Australian Northern Zone Rock Lobster Fishery (NZRLF). Since 1 November 2013, the use of a spike SLED has...

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&D capability on marine biotoxins and market access in Australia.

Summary

This report details the results of a multifaceted a research program led by the South Australian Research and Development Institute (SARDI). The work was undertaken to assist the rock lobster industry to understand food safety risks from a toxin naturally accumulated in the lobster hepatopancreas. The initial detection of the toxin resulted in closures of the commercial and recreational fisheries on the east coast of Tasmania in 2012. The research program comprised field sampling of lobsters and their prey organisms, experimental contamination in a biosecure facility, cooking studies, consumption assessments and a risk assessment exercise. The work was undertaken from August 2013 to February 2017.

Seafood CRC: bioeconomic decision support tools for Southern Rock Lobster

The Southern Rocklobster fishery is the most developed of the fisheries included in this series of projects because sophisticated bioeconomic models and stock projection capacity had already been advanced through previous research. This research takes the process further to extend the modelling...

Assessment of the implications of interactions between fur seals and sea lions and the southern rock lobster and gillnet sector of the Southern and Eastern Scalefish and Shark Fishery (SESSF) in South Australia

This report provides the most comprehensive appraisal of the risk posed by bycatch to subpopulations of Australian sea lions and New Zealand fur seals, by the SA rock lobster and gillnet sector SESSF fisheries. Further it has identified the research required to ensure that SA rock lobster and the...
