Following the Ministerial Direction, the NPF is likely to adopt an ITQ management system with a time line of 2010. The transition to a quota system requires research on methods of estimating total allowable catches (TACs). The NPF is a multi-species fishery. However, stock assessment has only been done for two out of the eight commercial species. Controlling catch of only two species cannot secure the long-term sustainability of the whole NPF. Therefore, a whole-fishery approach must be adopted, and stock assessment needs to be extended to a greater number of species.
Estimating TACs for annual species like the NPF prawns is challenging because recruitment and subsequent catches are greatly influenced by environmental variables and fluctuate widely. In the NPF, biological parameters are not uniformly known for all prawn species, and the characteristics of population dynamics differ from species to species. A tier-approach should be applied here like the SESSF, i.e. a formal stock assessment will be done for species supported by sufficient data; for others more empirical methods may be adopted. It is well known that the move from input to output control causes major changes to the catch rate data and can cause a major break in the time series.
A key management objective in the NPF is the maximisation of economic profits. TACs will, therefore, have to reflect this economic objective. Although the theory of maximum economic yield (MEY) is well established, such a management target has not been implemented in any fishery. Achieving such a target requires both methodological development and analysis of a number of factors not previously considered when setting TACs in fisheries.
In summary, this proposal is designed to meet the strategic need and provide the science, tools and technical support for the successful transition of the NPF to a quota management system.
1. Development of techniques for calculating and delivery of, TAC estimates for the two tiger prawn species and non-tiger prawn species that include both biological and economic information
2. Estimation of fishing power creep of the fishery
3. Assessessment of speces distribution for tiger and endeavour prawns to enable splitting group specific catch and effort data
4. Evaluation of economic efficiency under different TACs

Australia is at the forefront of economics based fisheries management, with explicit targets of maximum economic yield in Commonwealth fisheries and strong economic efficiency objectives in most States. The need to improve economic research capability in Australia to meet the needs of these management objectives has been recognized by FRDC through the economic capacity building project (FRDC 2008/306) and funding from the Seafood CRC to run a series of "Master classes" for managers and industry to explain the basic economic concepts that apply to fisheries management. While these programs have been successful, there is substantial benefit in attracting the world's best fisheries economists to present new ideas and methods that can ultimately benefit Australian fisheries and aquaculture industries. The aim of the conference is to attract such economists as well as practitioners (managers and industry) with strong economic focus. This also provides an opportunity to showcase the work being undertaken in Australia to an international audience, gaining strong feedback that will ultimately lead to improved economic analyses and hence management of Australian fisheries.

The ET&BF is presently dealing separately with a number of ecological issues. For example, impacts of longliners on shearwaters and turtles are current high profile problems. However, other issues such as depletion of swordfish, SBT bycatch, availability of tunas in relation to oceanographic features, bycatch of sharks and finning have all taken centre stage at different times in the short history of the domestic fishery. This approach is often reactionary, rather than strategic, and may not be the best use of research resources over the long-term. If the ET&BF is to move substantially toward ecosystem-based fishery management, as it is required to do under the EPBC act, rather than continue the individual species management approach, an ecosystem analysis providing ecosystem metrics must be developed. If, for example, ET&BF managers opt for time area closures as part of their management strategy to protect key species, developing these on a species-by-species basis has the potential to impact the whole fishery. To develop and evaluate time area closures that allow for minimizing risk of adverse impacts to the suite of key species, while allowing for optimal efficiency of fishing, understanding the associations, linkages and interactions between species is essential. This is the ecosystem approach. Developing an understanding of how ecosystem-associations relate to oceanographic features is also essential in open ocean systems where the dominant influence on distribution and local abundance is oceanography. The approach we are taking will provide the information needed to support an ecosystem-based management framework. Through the analyses we are proposing we will identify regional “hot spots”, detail their linkages and provide detailed scenarios as to how we think different management strategies and fishing practices will or will not impact pelagic food chains, ecologically related non-target species, competitors (e.g. sharks, marlins etc.) and their associated ecosystems. The need for ecosystem-based fishery management for the Western Pacific region has also been supported by PrepCon for the soon-to-be formed WCPFC (Working Paper 9, 2002).
1. Identify the spatial extent and the temporal stability of the main ecosystems of the eastern tuna and billfish fishery based on their species composition and physical environment.
2. Define the trophic structure within these ecosystems with emphasis on the relationship between target, bycatch and threatened and protected species.
3. Develop an ecosystem model for the ETBF fishery incorporating data on the relative abundance of the species, trophic linkages and the physical environment from which the impacts of longline fishing on the ecosystem can be investigated and from which alternative harvest strategies can be evaluated.

The SEF fishing industry, particularly the trawl sector, has a need to be proactive in the face of growing community attention to trawling based on its potential to modify benthic habitat and threaten biodiversity values. This need is focussed by the timetable for the regional marine planning process (the end of 2001 for the SEF region), as well as to meet provisions under Schedule 4 of the Wildlife Protection (Regulation of Experts and Imports) Act and the Environmental Protection and Biodiversity Conservation Act. Without solid information or a developed industry position regarding the spatial management of its fishing grounds, the fishing industry will have minimal ability to engage in this process as active partners.
The SEF fishing industry holds strong beliefs about the importance of particular seabed habitats for is continued profitability (Prince, Baelde and Wright FRDC 71/114) and has a need to develop a mature relationship with the National Ocean's Office and Environment Australia. This relationship and the information formailsed by this project will enable the industry to have input in the near-term to the Regional Marine Planning process and to certify their seafood products for expertation under the Wildlife Protection Act.
The outcomes of this project will have direct relevance t:
advancing AFMA's legislated aims of sustaining biological production and economic efficiency
seeking certification for inclusion on Schedule 4 of the Wildlife protection Act
attaining ESD accreditation in the longer term
responding to the near term needs of participating in the process of developing Environment Australia's South East Regional Marine Plan.
The finely detailed and annotated maps to be generated by this project will provide a template on which the distribution of fishing effort and catches can be plotted, and will form the basis of industry proposals to introduce a spatial management to their fishery. Without these maps and the process supported by this project there is a risk that uninformed spatial management of fishing effort would contribute neither to conservation goals nor the fishing industry and could be to the detriment of both. Moreover, inappropriate spatial management would be counter-productive to ESD planning for the SEF.
1. Proactively and cooperativley develop industry policy in response to the requirements of the Wildlife Protection Act (especially principle 2). 1.1 Acquire, collate and map industry (trawl and non-trawl) information on the spatial extent use of fishing grounds in the SEF.1.2 Evaluate and summarise this information in relation to the Wildlife Protection Act (especially principle 2) guidelines.
2. Integrate fishing industry knowledge and scientific data to give quality assured information on linkages between seabed habitats, biodiversity and fishery production for informed sustainable management of the SEF and to build broad understanding.2.1 Develop deployment equipment to provide an ongoing capacity to photographically monitor habitats from industry vessels.2.2 Validate and complement industry information gathered for objective 1 by ground-truth sampling from industry vessels.2.3 Consolidate all the information from this project, together with existing ecological and physical (geographical, topographical and hydrological) data, and provide a draft paper for industry that addresses relevant elements (primarily Principle 2 of the Wildlife Protection Act guidelines).2.4 Support, through a series of workshops, the development by industry of spatial management options to protect biodiversity and fishery production in the SEF based on the information provided through this project.2.5 Develop a Public Relations strategy for the project and its outcomes, including media release kits/releases and supporting video/photographic images, collaboratively between SETFIA, SENTA and the project team.
