Need

The low puerulus risk assessment report (attached- see bottom of page 9) suggests a 10-35% probability that the poor settlement on inshore collectors over the last 3 years could be caused by short term environmental changes. There is a growing concern amongst industry that short term environmental changes may indeed be responsible for a shift in the pattern of settlement from shallow to the deeper water. At the recent Western Rocklobster Council Congress it was suggested that industry driven research be undertaken, in collaboration with Department of Fisheries researchers, aimed at collecting post puerulus stage rocklobster in deep water to validate or refute anecdotal reports from fishermen of this phenomenon occurring in recent years.

It is envisaged that the findings of this study will assist in addressing the uncertainty around the suite of possible explanations for the poor puerulus settlement in the WRLF over the past three years and will aid in developing management arrangements now and into the future.

Objectives

1. To establish whether a shift in post puerulus settlment is occuring from shallow to deeper water.
2. To establish a new technique for conducting future research into post puerulus settlement

Tactical Research Fund: A collaborative approach to novel by-catch research for rapid development, extension and adoption into a commercial trawl fishery

Project number: 2009-069
Project Status:
Completed
Budget expenditure: $74,970.00
Principal Investigator: Cameron Dixon
Organisation: SARDI Food Safety and Innovation
Project start/end date: 28 Feb 2010 - 30 Aug 2011

FRDC

Need

This study is seen as a platform that will pave the way for a committed ongoing program of assessing, refining and ultimately adopting bycatch mitigation strategies in temperate South Australian prawn fisheries. This project was conceived from a high priority need to develop and test enhanced gear technologies that aim to: 1) reduce the incidental capture of bycatch species and 2) reduce the capture of small prawns. Both have the potential to maximise the value of the resource. This need was highlighted in the recent Gulf St Vincent prawn fishery (GSVPF) assessment report (Roberts et al., 2009).

The GSVPF is about to embark on a bycatch risk assessment process that will include a bycatch survey (March 2010), which will provide a unique opportunity to conduct this research in parallel at a significantly reduced cost.

This project will provide a template that utilises current fishery-independent trawl surveys to test new gear technologies. This work would follow on from previous valuable catch selectivity research (square mesh), and will provide management and industry with options for the way forward in terms of bycatch mitigation. This project will evaluate the effectiveness of novel trawl mesh (T90) at optimising catch selectivity and will be underpinned by pilot trials to be conducted at the expense of industry and SARDI. Furthermore, valuable underwater footage of operational trawl nets will be captured for the purpose of informing and optimising current and future net modifications / BRD trials (gear and bycatch behaviour). Information on species-specific trawl vulnerability, behaviour and differences in gear designs would augment the ecological risk assessment that the industry are undergoing.

Objectives

1. To provide a platform to test and develop enhanced gear modifications that minimise bycatch in temperate prawn trawl fisheries
2. To evaluate catch selectivity (prawn size and species-specific bycatch composition) of conventional diamond vs novel trawl mesh (T90) of two configurations
3. To capture underwater video footage of operational demersal trawl nets (conventional and modified) in a temperate prawn fishery to inform and optimise current and future net modifications / Bycatch Reduction Device (BRD) trials (gear and catch behaviour)

El-Nemo SE: risk assessment of impacts of climate change for key species in South Eastern Australia

Project number: 2009-070
Project Status:
Completed
Budget expenditure: $140,163.66
Principal Investigator: Gretta T. Pecl
Organisation: University of Tasmania (UTAS)
Project start/end date: 21 Dec 2009 - 30 Oct 2010

FRDC

Need

Climate change is expected to alter physical and chemical oceanographic conditions and processes around Australia, yet the influence this could have on the distributions of various marine species is still relatively unknown. The marine waters of South Eastern Australia are expected to be significantly affected by climate change, experiencing the greatest climate-driven changes in the southern hemisphere over the next century. The impacts and opportunities that will result from these changes will depend, in part, on how well the fisheries and aquaculture sectors and their managers respond to these challenges. A sound risk-based approach to informing both management arrangements and decisions by the sectors will be critical for optimizing outcomes. It is essential that the potential impacts of climate change on key resources are assessed and effectively communicated to support the development of policies that allow industry to minimize adverse effects by optimizing adaptation responses (e.g. by providing flexible management arrangements) and seizing opportunities as they arise (e.g. for species where productivity increases).

This project has been identified as a clear and immediate need through the SEAP Plan (draft) and also establishes a platform of baseline information from which we can start to address several key priority areas identified in the Draft Marine National Adaptation Research Plan (NARP). Priorities identified in the draft NARP include 1/ Which farmed species in which locations are most likely to be impacted as a result of climate change?, and for fisheries 2/ Which fishery stocks, in which locations, are most likely to change as a result of climate change? What will those changes be (e.g., in distribution, productivity) and when are they likely to appear under alternative climate change scenarios? Clearly, comprehensive and synthesised information on the sensitivities and tolerances of key species are the first steps required to address these priorities.

Objectives

1. Identify the life history stages, habitats and aquaculture systems of key species that may be impacted by climate change
2. Identify the physical and chemical parameters that may determine the potential impacts of climate change on key species
3. Conduct a preliminary risk assessment of each key species to the potential impacts of climate change
4. Highlight what additional information on the tolerances and sensitivities will be needed to develop bioclimatic envelope models for key species

People development program: Aquatic animal health training scheme-Fish disease diagnosis, biosecurity and disease management training for fish farming industry of Australia

Project number: 2009-315.28
Project Status:
Completed
Budget expenditure: $15,000.00
Principal Investigator: Rachel Bowater
Organisation: Department of Primary Industries (QLD)
Project start/end date: 30 Jun 2014 - 30 Dec 2015
Contact:
FRDC

Need

Training is needed, for fish farmers, technicians & veterinarians in all Australian States, for increased vigilance with respect to early disease detection, diagnosis, control and eradication of newly emerging endemic and exotic fish diseases. Northern States of Australia (NT, Qld) are at greatest risk for disease incursions, via the vast expanse of the States & Territories, remoteness of farms, illegal trade of fish, fish products, shipping movements (over 13 ports in Qld), people movement and the proximity of northern Australia to Indonesia, PNG and Asia. Early fish disease detection and eradication is necessary to protect the Biosecurity of the Australian Fish Farming industry, and prevent disease spread within and between States.

The continued annual growth of the barramundi & freshwater fish industries in all Australian States precipitates the need for farmer training for disease detection at the grass-roots level for farm workers to detect, control and treat fish disease, and thereby reducing disease risk to aquaculture enterprises and fisheries resources.

A specific training workshop is needed to train fish farmers, technicians, fisheries officers, vets, with hands-on, practical, technical skills & knowledge by Aquatic Animal health Professionals, so skills can be practically applied on farms during disease epizootics, investigations, and disease emergencies. This is needed to support continued growth, productivity, & sustainability of the Australian Fish farming Industry, disease being a limiting factor. This Workshop is needed to support on-going disease reporting activities by all States to DAFF, OIE and NACA, allowing continuation of Australian trade in fish and disease-free status.

Objectives

1. Develop and run a 3 day training workshop on fish disease sampling, disease diagnosis (endemic & exotic fish diseases), disease control, treatment, biosecurity, farm health management plans targeted at fish farmers, technicians, field & Government Veterinarians & fisheries officers to improve disease detection & reporting skills.
2. Produce training resources (Farmers Fish Disease Field Manual/, CD, posters, web-based) on fish disease sampling, diagnosis, identification, biosecurity, health management utilised by broad audience: fish farmers, technicians, veterinarians, universities, TAFE colleges, fisheries officers.
3. Training of 25 fish farmers (all States), technical staff, fisheries officers & 5 veterinarians in fish disease sampling, detection, diagnosis, treatment, control, biosecurity, disease response
4. Improved linkages, networking and communication between broader Industry (fish farm managers, operators, technicians), aquatic & terrestrial Veterinarians, fisheries officers, government officials (within /between Australian states), knowledge transfer and professional network development

People Development Program: Building seafood industry representational capacity

Project number: 2009-322

Principal Investigator: Neil Stump
Organisation: Seafood Industry Tasmania
Project start/end date: 31 Mar 2010 - 27 Aug 2012

FRDC

Need

The major need this project will aim to address is to build and enhance seafood industry representational capacity at the local and regional level. To achieve this, the project will meet the following specific needs for:

• novel ways to address barriers to the uptake of representative roles
• an entry through to intermediate-level training program which is a precursor to leadership training, and therefore contributes to a structured leadership training pathway
• training opportunities to upskill industry and non-industry representatives in areas of fisheries management principles, governance and decision-making processes, and basic representational skills, which use effective training delivery mechanisms and are supported by viable funding models

The needs this project targets are drawn directly from needs articulated in the background section of this proposal and in the following two reports.

Firstly, the FRDC’s People Development Program Plan 2008-2013has identified that there is “an urgent need to develop people within all sectors who have the skills to effectively contribute to debate and policy development for significant challenges confronting industry”. One of the objectives of the Program is therefore to “build industry capacity to drive change to achieve goals”.

To achieve this objective, the Program has recognized the following needs:
• strengthen governance and representational capabilities of industry organisations
• increase the capacity of industry organisations to represent the views of members
• enhance industry’s ability to contribute to debate and policy development
• build industry committee member competence and confidence

Secondly, the FRDC TRF Final Report ‘Understanding the Drivers of Fisher Engagement in Industry Bodies’ (Project 2009/335) has identified the need for the following:
• governance training program for fishing industry associations;
• industry associations to focus on representation as their major role;
• leadership training to be developed for teams of industry, and to be strategically funded.

Objectives

1. Identification of key knowledge areas and skill sets needed by fisheries resource users (commercial, recreational and indigenous fishers and marine farmers) and managers taking up representative roles at the local and regional level
2. Identification of novel ways to address barriers to the uptake of representative roles at the local and regional level for each sector, including effective training delivery models, viable funding models and other support mechanisms
3. Production of a comprehensive multi-level training tool-kit for the development of representational capacity at the local and regional level which is non-proprietarial
4. Provide the first steps of a structured leadership training pathway by conducting eight pilot training programs in four locations for over eighty members of the Australian seafood industry

Summary

This project has developed a comprehensive training package that builds representational capacity at the foundational level of the Australian seafood industry. 

The “Charting Your Own Course” training package incorporates four key training resources: 

  • Resource 1: Participant Workbook
  • Resource 2: Facilitator Guide
  • Resource 3: Self‐Paced Learning Manual
  • Resource 4: Advisory Committee Member Guide

These resources can be downloaded from the sections below.

This multi‐tooled training package approach will allow seafood industry associations and advisory groups to select the content and delivery style suited to their members’ needs. 

The concept of self‐paced learning has been included in the “Charting Your Own Course” training package. This training delivery method falls outside the seafood industry norm of workshops. Although workshops still hold a valuable place in seafood industry training, this project found that engagement with workshops by members of the seafood industry with no or minimal representational experience (the target audience) was poor. Self‐paced learning provides a delivery model that maximises flexibility in both the timing, cost and delivery of course content, which in turn should improve engagement with the training package content.

Summary

This project has developed a comprehensive training package that builds representational capacity at the foundational level of the Australian seafood industry. 

The “Charting Your Own Course” training package incorporates four key training resources: 

  • Resource 1: Participant Workbook
  • Resource 2: Facilitator Guide
  • Resource 3: Self‐Paced Learning Manual
  • Resource 4: Advisory Committee Member Guide

These resources can be downloaded from the sections below.

This multi‐tooled training package approach will allow seafood industry associations and advisory groups to select the content and delivery style suited to their members’ needs. 

The concept of self‐paced learning has been included in the “Charting Your Own Course” training package. This training delivery method falls outside the seafood industry norm of workshops. Although workshops still hold a valuable place in seafood industry training, this project found that engagement with workshops by members of the seafood industry with no or minimal representational experience (the target audience) was poor. Self‐paced learning provides a delivery model that maximises flexibility in both the timing, cost and delivery of course content, which in turn should improve engagement with the training package content.

Need

It is essential that the visions of Indigenous communities are accepted in holistic terms.

It is also important to note that while the visions of Indigenous communities could be the same or similar, they will also be independent due to the inherent cultural diversity of each community in relation to traditions, sites, stories and cultural practices.

Distinct rights exist for Indigenous people as part of their rights to self-determination. These rights should be recognised as inherent and holistic. They are:

• Customary fishing rights of Indigenous communities along the coastal and river systems; and
• Human rights to maintain a cultural economy

Customary rights relate to cultural self-determination and the preservation of distinctive cultural identities.

Human rights to maintain a ‘cultural economy’ relate to Indigenous communities being able to undertake activities that secure sustainable capital from the natural resources that traditionally and historically belong to each community.

Indigenous people want to be actively involved at all levels of management of fisheries resources throughout their traditional lands.

Indigenous people are very proud that they have survived the onslaughts of colonisation, assimilation and different forms of indoctrination and discrimination.

Indigenous communities believe that economic, cultural, environmental and social values should be given equal status when policy and management decisions are made.

A strong level of interest and enthusiasm for Indigenous involvement in the seafood industry already exists within Victoria’s Indigenous communities, but many communities are often unaware of the opportunities available or are unable to adequately assess them.

Numerous Indigenous communities have recognised that opportunities are not being made available within their regions to retain their youth. Many groups believe that economic development (particularly in the seafood sector) may act as a logical pathway to retaining youth and achieving more healthy vibrant communities and futures for their families.

Objectives

1. Ensure adequate financial support is obtained in a 'whole of government' approach
2. Ensure programs are strategically administered to reach optimal outcomes

Need

The needs addressed by the project were identified and developed through the extensive consultation process. They were:

1. The collection of information on the economic performance of the fishery in each state and incorporation of this into the annual assessment process. The intent here was to better integrate economic and biological data into the decision making process for management.

2. Bioeconomic modelling capability is required by modifying the existing stock assessment model used across the fishery to incorporate economic data and an economic submodel to compute net economic return under different harvest strategies or management regimes. This economic analysis capability has been developed in Tasmania (and will be improved) but there is no capacity in the other two states. A bioeconomic model will provide the capacity for managers and industry to formally conduct cost-benefit analyses on decisions about future management of the fishery.

3. There needs to be effort put into exploring better management for the fisheries (using the bioeconomic model). This includes different TAC options, size limits, and seasons (ie harvest strategy evaluation, HSE). This requires industry and government steerage to propose new strategies and review model outputs. It also requires a shift in decision making where management tries to target the best economic outcome for industry rather than merely ensuring stock sustainability.

4. There needs to be testing of the pathway in making SRL fisheries more profitable. Steps 2 and 3 above can be used to define better management approaches but how would they be implemented? It's one thing to define a profit maximising TAC with a bioeconomic model, but would this system really work with year-to-year volatility in recruitment, prices and costs. (Formally, this means management strategy evaluation of economic control rules, which respond yearly to changing stock and economic indicators.)

Objectives

1. Define baseline economic performance of participating Southern Rock Lobster fisheries
2. Produce bio-economic analysis tools for Southern Rock Lobster fisheries
3. Determine economically optimal management strategies using integrated stock and economic models, including seasonal, size and TAC combinations
4. Communicate management and harvest strategy opportunities identified in Objective 3

Summary

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 tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

Summary

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 tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date.

Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

Summary

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 tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

Summary

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 tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

Summary

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 tools to other states and to examine the use of economic control rules.

This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

Summary

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 tools to other states and to examine the use of economic control rules.

This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

This research takes the process further to extend the modelling tools to other states and to examine the use of economic control rules. This means, for example, that it would be possible to evaluate how feasible it would be to target maximum economic yield in the face of price volatility. This level of bioeconomic analysis capability is only available elsewhere in Australia in the Northern Prawn Fishery, Australia's best example of the use of economic data for management to increase profits.

This project also aimed to produce bioeconomic analysis tools for Southern Rocklobster fisheries and determine management strategies using economic models. Economic data for Tasmania were collected, and a lobster fishery projection model was produced which permits the testing of a wide range of strategies, specifically to evaluate each strategy’s economic performance. Using this model, the profit expected under each strategy was estimated.While the analysis showed a small impact of opening the fishery for all 12 months, this analysis is only preliminary and is greatly limited by the lack of any data for winter fishing in South Australia since these two zones have been closed to winter fishing to date. The best policy was a yearly quota-setting harvest control rule designed to seek an approximately constant yearly harvest fraction (a constant exploitation rate). By setting the total allowable catch yearly to remove an approximately constant fraction of the available lobster biomass, three of four important management objectives were optimised.

Need

• There have been numerous trade failures regarding exportation of Australian prawns into Asia and Europe. These mainly relate to cadmium and Vibrios. ~4900 tonnes wild caught prawns were exported in 2007/2008 compared with total capture of 19,000 tonnes.

• Due to these trade issues the Seafood Access Forum have ranked Vibrios and cadmium as ‘high priority’.

• Vibrios have been responsible for illness outbreaks in Australia. Due to the role of Vibrios in illness outbreaks Codex is progressing standards on the control of Vibrios and domestic requirements for testing are increasing e.g. Woolworths requires testing for Vibrio cholerae.

• Standard laboratory methods are time consuming and don’t differentiate ‘disease-causing’ and ‘non-disease causing’ strains and so they ‘overscore’ (‘false positives’). The lack of this capability hampers efforts to dispute trade detentions related to the presence of Vibrios.

• This project aims to address this need by developing a rapid method that distinguishes pathogenic and non pathogenic V. parahaemolyticus, V. cholerae and V. vulnificus to underpin domestic and international trade requirements.

• Cadmium trade failures are related to the low maximum level set by the EU and some Chinese jurisdictions. Attempts by the Australian government have been unsuccessful in negotiating a higher limit.

• Recent data published on nutrients in food that may mitigate the adsorption of cadmium by humans has not been fully considered by regulatory authorities. Consideration of this may support the Codex position that no limit is required.

• This project aims to provide a risk-benefit assessment on cadmium in prawns to underpin further multi-lateral trade negotiations and Codex.

• Other potential food safety risks to the prawn industry will also be assessed and key areas of concern will be prioritised to assist in directing resources to issues of high business risk.

Objectives

1. Establish a recognised capacity to assist industry with domestic and international trade issues/failures related to V. parahaemolyticus, V. cholerae and V. vulnificus in prawns.
2. Generate data on levels of cadmium, iron, zinc, selenium and calcium in prawns to support risk-benefit assessment.
3. Undertake a scientific risk-benefit assessment on cadmium, iron, zinc, selenium and calcium in prawns to underpin future trade negotiations and support the Codex position that a standard is not required
4. Assess and rank the risks (food safety and trade related) to the prawn industry and prioritise key areas of concern to target risk reduction initiatives in the future.

Summary

Australia typically produces around 20,000 tonnes of prawns annually, of which around 25% is exported. The Australian Prawn Fisheries Council (APFC) and the Seafood CRC commissioned SARDI to undertake a food safety risk rating of prawns consumed in Australia. This project scientifically evaluated the human health impact of chemical and microbial hazards associated with prawns.

Risk ratings indicate a very low risk of human illness associated with the consumption of prawns produced domestically, imported prawns and exported prawns. This finding is consistent with the public health record which shows few reports of illness related to the consumption of prawns that have been handled appropriately

This project scientifically evaluated the human health impact of chemical and microbial hazards associated with prawns.

Risk ratings indicate a very low risk of human illness associated with the consumption of prawns produced domestically, imported prawns and exported prawns. This finding is consistent with the public health record which shows few reports of illness related to the consumption of prawns that have been handled appropriately
