Need

There is a risk that Queensland’s deepwater (>200m) fish stocks are being fished at levels that are not sustainable Increased effort by commercial fishers in deep waters under normal line entitlements and the lack of knowledge of many of the targeted deepwater species (many of these species are presumed to be long-lived, schooling species susceptible to overexploitation) are key threats.

There is also anecdotal evidence that recreational fishers are fishing further offshore in deeper water and that recent improved fishing technologies have increased the effective effort on deepwater fish by all sectors. It is imperative that basic information on these deep-water stocks is collected at a time when management arrangements are being updated for rocky reef species (both shallow and deepwater).

The DEEDI Fisheries Observer Program has 100 days allocated to the deepwater fishery next calendar year, providing a unique opportunity to gather additional biological information on deepwater species that would not normally be collected as part of the routine core functions of the program. The provision of resources via a short-term “Tactical Research Fund” proposal would provide additional information at a time that is critical in the management cycle. It would also enable an assessment of the impact of improvements in vessel and gear technology (braided line, soft plastic lures, GPS etc) that could be used to better standardise catch rates. This is an essential requirement in any future stock assessments.

Fisheries Queensland is currently undertaking a gap analysis to identify information needs for completing an ecological risk assessment of this fishery. The proposed research is critical as it is designed to address the data deficiencies identified by that analysis.

Fisheries Queensland has identified this issue as a priority to be addressed over the next 18 months with a view to review management arrangements in 2012.

Objectives

1. Quantify recent changes in fishing technology in the commercial, recreational and charter line fishing sectors and evaluate the extent to which these changes could impact on the sustainability of deepwater fish species.
2. Collect and analyse biological data on key deep-water line caught fish species in collaboration with the fisheries observer program and collate information identified by the gap analysis currently being undertaken by Fisheries Queensland.
3. Assist Fisheries Queensland in developing an ecological risk assessment for deepwater fin fish species.

Need

The NSW Department of Primary Industries continues to work with the NSW commercial fishing industry to investigate structural changes to the management of commercial fisheries which will lead to improvements in efficiency and profitability. One issue that requires consideration in these deliberations is the highly variable inshore-offshore production that is linked with rainfall in coastal NSW. Such changes are exacerbated during periods of drought or flood and result in significant shifts in the behaviour of fishers. It is expected that such variations in rainfall will continue, and are likely to become more extreme, under projected climate change scenarios.

This project will examine the NSW commercial catch records and ascertain if there are patterns of endorsement holdings that are the basis of more robust fishing businesses during periods of drought or flood. We expect that many fishers will understand these patterns based upon extensive practical experience, but an empirical confirmation of such patterns will lend additional weight to any associated decisions by government and industry.

This project will also shed light upon an important facet of risk management in fisheries. The textbook economic argument that increased specialisation results in increased efficiency must be contrasted with potential lost opportunities for fisheries production in a highly variable environment. The adage "don't put all your eggs in one basket" is likely to be highly applicable for inshore and coastal fisheries in NSW. Increased specialisation will likely be associated with costs as well as benefits.

Objectives

1. Identify the patterns of fishing endorsements that will make NSW fishing businesses more robust to the likely changes in freshwater flow that will result from climate change.

Towards a national strategy for mud crab research - mud crab workshop

A workshop was held in Darwin, the Northern Territory (NT) in May 1999, to develop a National Strategy for Research on Mud Crab ( Scylla sp.) in Australia. Fisheries managers and researchers from Western Australia, the NT and Queensland attended, along with Industry representatives from the NT. The...

Genetic study of ocean jacket populations - Pilot study

Ocean jackets (Nelusetta ayraudi) are distributed from North West Cape (W.A.) through southern coastal waters to the south of Queensland. They have not been recorded from Tasmanian waters. Seawards their distribution ranges from coastal embayments where juveniles school seasonally to waters just off...

Causes of decline in stocks of commercially important prawns in the Northern Prawn Fishery

The following report is a description of the two FIRTA projects (85/85 & 89/13) which examined recruitment processes in penaeids at Albatross Bay in the northeastern Gulf of Carpentaria over the years 1985 to 1992. The aim of the first of the two projects was to identify the main factors which...
