Need

The current ASI selective breeding strategy has operated successfully since 1998 (for 6 generations). It is now apparent that there are shortcomings to this strategy and major improvement is needed if the program is to be seen as “state of the art”. This proposal addresses three major needs identified as part of FRDC project 2005/227.

Firstly, there is a need to design a program that maximises profit. Selection for traits in the current ASI breeding program cannot be based on economic criteria because the economic values of Pacific oyster traits are unknown. There is a need to know the dollar value of current traits (growth rate, shape and uniformity) as well as the value of new traits. The program is unable to objectively select multiple traits without knowledge of economic weights. This proposal will use techniques used routinely in other industries to address this problem.

Secondly, there is a need to design a program that increases the rate of genetic gain. It has been estimated (FRDC project 2005/227) that gains per unit time could be doubled through addressing issues such as selection methodology, breeding population sizes, and the breeding cycle. This proposal will find the most cost effective alternatives for the Pacific oyster industry.

Thirdly, there is a need for specification of hatchery facilities which can accommodate the inclusion of additional breeding families and a data management system which complements systems for genetic evaluation and best mate allocation.

This project involves research and development of concepts which are entirely new to breeding programs for the Pacific oyster, or any other aquaculture industry. They are concepts which are well established in some land based industries. It is essential that these concepts are developed for aquaculture so that breeding programs can provide the best possible foundation for viable aquaculture industries.

Objectives

1. To upgrade and refine the ASI breeding program by developing a program that maximises economic gains and identifies the relative importance of traits known to be significant for the Australian Pacific oyster industry.
2. To upgrade and refine the ASI breeding program by production of a spreadsheet to calculate the economic values of traits for Pacific oysters enabling regular updates and customization to individual regions.
3. To upgrade and refine the ASI breeding program by determining the breeding strategy that delivers the best genetic gains for the Pacific oyster industry and fits within the resources available to ASI.
4. To upgrade and refine the ASI breeding program by documenting the genetic gains possible with different oyster selective breeding strategies and the relative economic benefits of these different strategies.
5. To upgrade and refine the ASI breeding program by developing specifications for a facility to produce the required number of families.
6. To upgrade and refine the ASI breeding program by developing specifications for computer systems to support the breeding program (ie best mate allocation and genetic evaluation).
7. To upgrade and refine the ASI breeding program by updating the ASI Data base to accommodate the requirements of the revised breeding program.
8. The development of a model for data capture and processing for further development by ASI and consideration by other aquaculture sectors.
9. To update ASI's existing business plan on an annual basis, clearly outlining the future business case of ASI and detailing the copmpanies exit strategy from reliance on FRDC funding.

Summary

The Australian national Pacific oyster selective breeding program commenced in 1998.  In 2005, after 6 generations of breeding, it was apparent that there were limitations to the breeding strategy.  The first was a lack of understanding of which genetic traits to select. Whilst the program was achieving genetic improvements in growth, little was known about which traits influenced grower profitability.  The second was a need to develop a breeding strategy that increased genetic gains and maintained inbreeding at safe levels.  And the third was a need for systems and tools to enable the breeding strategy to be efficiently implemented.  The purpose of this project was to address these limitations.

This project has resulted in significant changes to the ASI Pacific oyster breeding strategy. The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

Summary

The Australian national Pacific oyster selective breeding program commenced in 1998.  In 2005, after 6 generations of breeding, it was apparent that there were limitations to the breeding strategy.  The first was a lack of understanding of which genetic traits to select. Whilst the program was achieving genetic improvements in growth, little was known about which traits influenced grower profitability.  The second was a need to develop a breeding strategy that increased genetic gains and maintained inbreeding at safe levels.  And the third was a need for systems and tools to enable the breeding strategy to be efficiently implemented.  The purpose of this project was to address these limitations.

This project has resulted in significant changes to the ASI Pacific oyster breeding strategy. The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

Whilst the program was achieving genetic improvements in growth, little was known about which traits influenced grower profitability.  The second was a need to develop a breeding strategy that increased genetic gains and maintained inbreeding at safe levels.  And the third was a need for systems and tools to enable the breeding strategy to be efficiently implemented.  The purpose of this project was to address these limitations.

This project has resulted in significant changes to the ASI Pacific oyster breeding strategy. The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

The breeding objective has changed and is now firmly focused on an economic outcome, which is to reduce the cost of production.  The size and structure of the breeding population has changed to allow greater genetic gains on a sustainable basis.  The goal is to produce 50 families per year and 42 families were produced for the 2009 year class, an increase from 24 families in the previous strategy.  A new nursery system has been implemented to produce the expanded population.  Data collection and storage systems have been completely revised to allow more efficient data collection, more efficient storage, and safeguards against data loss. A new genetic evaluation system has been implemented which will provide more accurate selections.  And a revised commercial deployment strategy has been implemented which will increase the supply of selectively bred spat to industry.

Need

The SRO industry has the potential to exploit new export initiatives and increase production. Any resurgence in the industry will depend on SOCo’s ability to manage the development and supply of selectively bred oysters. FRDC has fostered this process by supporting breeding programs and hatchery research, whilst encouraging industry management of technology. The Benzie Report, Oyster Research Advisory Committee (ORAC) R&D Strategic Plan and the Action Plan developed at the FRDC-funded QX workshop in June 2005 have all indicated that effective management strategies for the SRO industry must be underpinned by; 1) the continued development of oyster husbandry techniques to secure QX resistant breeding lines, and, 2) the identification of genes associated with QX disease resistance that can be used for marker-assisted selection. These complementary research goals represent a critical step in “QX proofing” NSW estuaries against ongoing and catastrophic QX disease outbreaks. Continued research may also allow farming to be re-established in areas abandoned because of QX disease. Integration of genetic markers and single pair mating into the hatchery-based breeding program will increase the efficiency of selection, and decrease the number of generations required to establish true breeding resistant lines. Without marker assisted selection, the breeding program may not reach its full potential in time to prevent further losses.

A comprehensive presentation on the SRO industry will be given during the FRDC board’s visit to Port Stephens in July 2006.

Objectives

1. To establish pair mating protocols necessary for the development of selectively bred oyster lines
2. To confirm the association between PO and QX resistance using pair matings and test the performance of PO-selected family lines in QX-prone estuaries
3. To identify and characterise additional genetic markers of disease resistance
4. To assess the value of cryopreservation to secure family lines for later use
5. To assess the use of non-chemical means for the induction of triploidy in SRO
6. To make the family lines produced in this research available to SOCo for incorporation in future breeding plans

Summary

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

Summary

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10).

Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

Summary

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

Summary

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field.

While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

Summary

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

These families will be made available to SOCo for incorporation in the industry breeding program.

Summary

The Select Oyster Company breeding plan has been amended to include a comprehensive manual of protocols for pair mating Sydney rock oysters (4.1). The association between phenoloxidase (PO) and QX resistance has been confirmed and a sensitive test for PO genotypes has been developed so that the breeding program has a tool to genotype parents and large numbers of their progeny to assist breeding (4.2-4.8). Protocols for cryopreservation of gametes have been developed and documented as a potential strategy to reduce SOCo’s overall maintenance costs for the lines and increase genetic security (4.9). Non-chemical means of triploidy induction in SRO (temperature and pressure shock) were tested (4.10). While these techniques were not as effective as existing chemical induction techniques, they have formed the basis of ongoing research to see if efficacy can be increased. A total of 60 pair mated family lines, including 31 lines with differing PO phenotypes, have been produced and are undergoing performance assessment in the field. These families will be made available to SOCo for incorporation in the industry breeding program.

Need

The tuna industry in Australia is limited by catch quota. Increased competitiveness through production
efficiency is the main way to improve the value of the industry. Improved performance can be achieved through stress reduction and minimising mortalities. These issues will also be crucial for longer term holding, when the initial size of tuna will be smaller and the fish will be farmed for a longer time, increasing health risks to the tuna.

Tuna are hardy under current husbandry practices, and the industry experiences low mortality
The wild capture of immunocompetent 3 – 5 yr old fish is the main reason, however the short growout
time and advances in farming technology have been significant factors. Despite its newness,
the industry enjoyed healthy returns for the first 10 years.

Since 2002 there has been a significant fall in revenue (prices down over 50% and strengthening of
the Australian dollar). The worsening financial parameters, combined with the intrinsic high ‘value’ of
each fish, have placed a greater focus on all aspects of the industry and particularly stress impacts
limiting production. Mortality is an obvious area and the current level is no longer acceptable. Possibly
more important, stress may cause economic costs to the tuna industry in lost growth and condition. There is a potential for increased productivity through stress reduction.

The quota places a limit to what biomass can be farmed each year. Rather than merely growing out for
3-6 months, the option of longer-term holding is a priority to increase productivity. Then the role of stress and the influence of husbandry practices on fish health and production are even more important.

As each individual fish has high commercial value, there is a need to develop non-lethal indices for SBT
monitoring. Predictive indices will be valuable for planning production and harvesting.

Objectives

1. to investigate the relationship between husbandry practices and SBT performance (at the level of tow and pontoon)
2. to investigate development of nonlethal indices for SBT health and performance and assess their predictive value
3. to determine the relationship between SBT health, stress and fish preformance (individual fish level)

Need

The Strategic Plan Summary (FRDC 2002/313) reports as follows:
For all its economic promise the industry faces some challenges that constrain growth and profitability:
• Lack of appropriate peak body structure and supply chain fragmentation
• Limited enterprise commitment to joint industry development
• Complacency in dealing with market issues – predominant wild caught focus
• Limited sectoral or peak body strategic planning
• Policy dominated by resource managers and technologists rather than those with commercial and market experience.

The industry structure comprises around 700 small owner operator businesses with little or no capacity to coordinate investment in and manage industry development. Recovering lost industry value and delivering future growth is contingent upon coordinated investment in industry development at the whole of industry level.

SRL is now established and positioned to implement the strategic plan, and integration of R&D work across stakeholders, States, Australia and New Zealand, rock lobster subprograms, researchers and other related disciplines is now feasible under the leadership of SRL.

Two distinct needs are involved in any consideration of better national R&D co-ordination for the southern rock lobster sector:

1. The strategic issues of R&D prioritization, funding and the linkages to (and support for) both industry development plans and Government objectives of industry development.

2. The operational issues of facilitating effective communication and coordination at all levels (industry/researchers, among researchers, among industry, FRDC/researchers etc).

Objectives

1. To coordinate the investment by FRDC and SRL to achieve the planned outcomes detailed in the SRL Strategic Plan
2. Provide a communication and extension service that complements the individual projects to facilitate adoption of outputs
3. To provide reports to FRDC and SRL Ltd that demonstrate effective management of the individual projects, and contribute to good governance
