Strategic Planning Workshop for Yellowtail Kingfish Stock Assessment in South-Eastern Australia
Improving and promoting fish-trawl selectivity in the Commonwealth Trawl Sector (CTS) and Great Australian Bight Trawl Sector (GABTS) of the Southern and Eastern Scalefish and Shark Fishery (SESSF)
It is very clear that fishing-technology research to improve resource harvesting is a priority need for the future sustainability of fish trawling in Australia. The issue is quite poignant, considering that over the past 15 years, there has been a massive reduction in the total number of trawlers in Australia, and lower profits among remaining operators struggling to remain viable. Innovative modifications and refinements to existing systems that improve selectivity and reduce environmental impacts and costs are an urgent priority to ensure economic viability. Such developments are difficult to achieve by individual fishers without quality research, development and extension that is adequately resourced.
More specifically, there is a clear need to maintain progress towards developing innovative, high-priority technological modifications to fish trawls in the CTS and GABTS that mitigate sustainability issues while maintaining target catches at existing levels. Equally important, ratified designs then need to be tested across fleets to encourage adoption and refinement as a precursor to eventual legislation. Ultimately, satisfying these needs will contribute towards improving the social licence and economic return of trawl fisheries in the SESSF, while helping to ensure their ongoing sustainability and address what remains one of the most controversial issues facing bottom trawling.

Evaluation of practical technologies for Perfluoroalkyl (PFA) remediation in marine fish hatcheries
Per- and poly-fluoroalklys (PFASs) are now emerging as pollutants with potentially catastrophic impact on aquaculture facilities. Two key research institutes have already demonstrated the presence of PFASs in marine fish broodstock and have observed impacts on offspring that are consistent with those observed in
literature studies. As testing continues there is the expectation that the number of facilities affected will increase. To compound the challenge our understanding of the impacts of PFASs on aquatic species is limited. In order to further assess these impacts, PFASs must be introduced into experimental systems in a
controlled fashion and therefore we must have the capacity to remove those pollutants before release. To protect our facilities and permit PFAS impacts research there is a need to rapidly assess available PFAS treatment technologies.
