Indices of recruitment and effective spawning for tiger prawns stocks in the Northern Prawn Fishery
In the mid to late 1980s NORMAC began to suspect that tiger prawn spawning stocks in the NPF may have been reduced by fishing to levels that reduced recruitment to the fishery. A vessel buy-back scheme and other effort reductions were introduced to reverse this trend but, by the mid-1990s, the...

ASFB workshop: towards sustainability for data limited multi-sector fisheries
FRDC and State agencies have generously supported an annual national workshop hosted by Australian Society for Fish Biology (ASFB) since the 1980’s. At the workshop, Australian and overseas scientists have presented keynote addresses on the theme of the workshop, followed by panel debates. The...

The need for the research lies in the fact that no guideline values exist for pectenotoxins in shellfish. To produce these guidelines toxicological data need to be produced and currently there is a lack of knowledge of the PTX metabolism and mechanisms of toxicity. There is currently no oral toxicology data on the PTX2- seco acids and thus their inpact on human health cannot be assessed. There have been no published works of their metabolism in mammals or humans, and their chronic effects on health are unknown. The clinical symptoms are non-specific to DSP poisoning and it is believed that cases of bacterial poisoning and DSP are mis-diagnosed due to lack of toxicological information.
The presence of pectenotoxins can impose significant economic burden on the shellfish industry. Clear toxicological data on pectenotoxins will be used to undertake a risk assessment of pectenotoxins to enable the shellfish industry and regulators to make informed decisions about the withdrawal of product from sale or closure of farms in the presence of pectenotoxins in shellfish.
1. A comprehensive study has been undertaken in which the aims are to (i) develop a robust method for extraction, purification and quantification of pectenotoxins in shellfish, (ii) investigate the pathology caused by the pectenotoxins when ingested orally, (iii) investigate P450 metabolism of the purified PTXs with the use of microarray technology and (iv) conduct a health risk assessment for the consumption of seafood contaminated with pectenotoxins. This study will provide a greater understanding of the metabolism and mechanisms of toxicity for the PTXs and provide information useful in the clinical assessment of poisoned patients and also provide information to be used in the setting of guideline values for pectenotoxins in seafood.
