This project will partner with QOGA and other stakeholders to address the identified need to establish new oyster farming options, technologies, and production systems. The RD&E requires a dual focus, to both improve viability of the current SRO sector, and initiate commercialisation of new TRO varieties for expansion beyond SEQ.
Recent flood events have emphasised the urgent requirement to further improve the quality and availability of QX resistant SRO stock. It is a QOGA priority to have QX resistance validation trials conducted in Qld to determine the most viable SRO options for SEQ. Validation will be undertaken in collaboration with NSW DPI (building on FRDC 2016/802) and will link with farm-based growout trials conducted at strategic sites, assessing performance relative to location and system. Outcomes will also form a benchmark for direct comparison with newly identified lineages.
With the identification of new TRO varieties (FRDC 2018-118), QOGA advocates that both BRO and LGRO require thorough investigation and the development of targeted hatchery and growout research including farm-based production trials. This aligns with QOGA’s need to access additional culture species options with increased temperature tolerance (essential for northern expansion and climate-change security) and potential QX resistance.
A research hatchery has recently been established to address QOGA’s request for a dedicated R&D hatchery. The hatchery is already producing priority oyster strains (SRO & BRO) and is capable of undertaking this required research and meeting the industry’s immediate requirement to access spat.
To efficiently address the Qld oyster industry’s stated priority needs, this project will undertake research that combines new genomic sequencing and hatchery technologies, best practice production processes and expert local oyster farmer knowledge.
Objectives: 1. Overall:Provide an assessment of the most regionally appropriate oyster species and associated production protocols capable of improving oyster farm productivity and achieving broad industry expansion within and beyond SEQ. 2. Hatchery and nursery:Improve hatchery and nursery production capacity to support R&D activities and provide Qld farmers with additional spat while developing more efficient hatchery/ nursery processes that include advanced molecular processes for improving reproductive capacity, gonad conditioning and reliability of spawning. 3. Blacklip Rock Oysters:Provide reliable BRO spat production capacity that meets the short-term stocking and start-up needs of Qld BRO farms. Develop locally relevant production protocols and determine BRO farming suitability at specific locations along the Qld coastline, while integrating with and contributing to broader CRCNA RD&E activities. 4. Lineage G Rock Oysters:Provide reliable LGRO spat production capacity that meets the short-term stocking and start-up needs of Qld LGRO farms. Develop novel hatchery, production, and post-harvest assessment protocols for LGRO. 5. Sydney Rock Oysters:Improve understanding of SRO QX resistance through validation trials assessing the benefits of QX resistant strains under SEQ conditions. Develop information on production parameters and systems for specific SEQ farming locations to assist with development of best practice production protocols. 6. Genetics and distribution:Develop conclusive, oyster industry focussed, genetic information detailing BRO and LGRO distribution and diversity along Queensland’s east coast. This information is essential for assessing geographic aquaculture potential at both a species and population level and developing appropriately informed management and stocking policies. 7. Non-destructive sampling:Develop refined sampling and genetic identification technologies to achieve accurate, rapid, and non-destructive broodstock identification procedures. This is necessary to ensure that hatchery activities can reliably identify and produce the required species or population. Read moreRead less

Workshops have been well supported and have included participants from Government and private laboratories and the aquaculture industry. Industry participants have been from a diversity of farms and representative of a wide variety of aquaculture species. The participant numbers have increased at each workshop from 17 to 35- ideally the maximum group size of 35. This maximum number allows the workshop to be conducted at various locations, as it is not too large a group for host facilities to accommodate. Previous workshops have led to the exchange of information and methods. This has provided ongoing contacts established at the workshops, for participants to discuss issues, and in turn, respond more effectively to disease outbreaks. With aquaculture facilities and the species farmed continuing to expand in Australia, transferring these vital skills and knowledge to a new generation of researches and those involved in aquatic animal health, will be of benefit to both the aquatic animal health sector and industries. Due to budgetary constraints in both Government and industry sectors, funding is required to assist workshop participants with travel expenses to attend the workshops. Without partial travel subsidy many forum participants would not obtain authorization to participate. This has repeatedly been raised in feedback and would affect attendance.
The exchange of information and pathways for new people involved in aquatic animal health will be lost and need to be re-established if the workshops fail to continue on an annual basis.
Objectives: 1. Source workshop venues, in various States and Territories, that have aquatic animal health capability or services and can accommodate the group size. 2. Organise all aspects of conducting the workshops including; advertising through Health Highlights subscription and peer referrals, guest presenter, presentation program, field trips and practical sessions, accommodation and catering. 3. Encourage new and emerging science and production staff to attend the AAHTF and to gain experience in making presentations 4. Continue to update the contact list and email distribution list/group for continued information exchange 5. Reports and financial acquittals prepared according to milestone schedule.

A number of southeast Australia fish stocks have failed to 'recover' following substantial reductions in catch and effort, and a number of research projects have concluded that some of these have undergone an environmentally-driven reduction in productivity. A productivity shift has already been demonstrated for Eastern Jackass Morwong, with the stock-recruit relationship and reference points being adjusted to reflect this change. Ecosystem and climate-change modelling have predicted increasing likelihood of similar changes in productivity for a number of Australian fish stocks.
Current harvest strategies assume either equilibrium or some average B0, and associated target (B48) and limit (B20) reference points. Use of equilibrium B0-based reference points and harvest strategies do not correctly reflect the natural dynamics of stocks where productivity changes. This can lead to sub-optimal management, either over-utilising a reduced productivity stock or under-utilising an increased productivity stock. In contrast, reference points based on some proportion of naturally variable unfished biomass (Bunfished or dynamic B0) will fluctuate to follow environmentally-driven productivity changes. Dynamic reference points have been evaluated and adopted for a number of international fisheries.
The need to adapt stock assessment methods and harvest strategies to explicitly and justifiably account for shifts in productivity has been recognised by the AFMA Resource Assessment Group for the Southern and Eastern Scalefish and Shark Fishery (SESSF), not least as a result of clearly evident declines in biomass (Jackass Morwong, Redfish) or recruitment (Silver Warehou) that cannot be attributed to fishing under current productivity assumptions.
Objectives: 1. To review relevant international research and management approaches to account for environmentally-driven productivity change in stock assessments, reference points and harvest strategies for selected Australian fish stocks. 2. To identify and describe circumstances and fish stocks for which dynamic reference points should or should not be used in stock assessments and harvest strategies, and develop appropriate methodology for conducting assessments using dynamic reference points. 3. To identify selected candidate fish stocks showing likely environmentally-driven productivity change, conduct comparative assessments for these stocks using equilibrium and dynamic reference points, and prepare a candidate harvest strategy that includes dynamic reference points for testing in the FRDC Multi-Species Harvest Strategy project. 4. To make recommendations on future implementation of dynamic reference points and harvest strategies for Australian fish stocks. 5. To develop and improve methods for detecting and quantifying changes in productivity (growth and recruitment) in stock assessments, to relate these to environmental mechanisms causing productivity changes, and to evaluate data needs, including environmental indices, required to usefully detect and evaluate productivity change under various circumstances. 6. To consider and evaluate options for effective harvest control rules, incorporating dynamic reference points, that might appropriately respond to changes in fish stock productivity, including environmentally driven trends in productivity. 7. To identify environmental circumstances and fish stock characteristics under which it would be appropriate and advisable to move to using assessments and management approaches incorporating dynamic productivity and reference points, vs. stocks for which dynamic approaches offer no benefit compared to existing equilibrium approaches. 8. To make recommendations on future stock assessment approaches, data requirements, harvest control rules and management approaches incorporating environmental indicators, dynamic productivity and dynamic reference points for Australian fish stocks.

Stock status in the EGPMF is assessed by monitoring fishery-independent and fishery-dependent catch rates (used as indices of recruitment and spawning stock levels) relative to specified reference points. However, in recent years factors other than the spawning stock index appear to be responsible for low levels of prawn recruitment. Given recent indications that the distribution and abundance of seagrass habitats may influence prawn recruitment there is a need to better understand the relationship between prawn recruitment, environmental conditions and habitats. Understanding these relationships is required to clarify the uncertainty around stock fluctuations and improve stock assessments. The information is also required so that management can be more cognisant of the impacts of environmental conditions on annual recruitment variability and implement adaptive management strategies, such as altering seasonal arrangements, to prevent overfishing.
Similarly, the recent MSC assessment of the EGPMF fishery has highlighted the need to clarify the uncertainty in fishery independent surveys and stock assessments including the influence of environmental factors on indices, and collect environmental and habitat data to detect changes in risk to habitat due to fishing including ongoing monitoring of critical habitat types.
Therefore, the development of broad scale fishery specific, cost effective monitoring techniques is essential to assess and monitor the association between critical fish habitats, environmental drivers and prawn recruitment. These techniques need to be developed at appropriate temporal and spatial scales to allow for early intervention of appropriate management measures, such as adjusting spatial and temporal closures, to ensure the long term sustainability of stocks and maintain MSC certification. Given that recruitment in a number of the State’s other invertebrate fisheries appears to be influenced by environmental drivers developing techniques to understand these relationships is a critical component of ensuring the management of WA’s fisheries resources is based on robust science.
Objectives: 1. Collate and review historical, satellite, habitat and environmental data for the Exmouth Gulf and Shark Bay ecosystems to identify factors that may influence recruitment. 2. Assess the ability of different techniques, at various spatial and temporal scales, to identify, assess and monitor critical fish habitat and environmental conditions which may affect recruitment patterns of prawns into the Exmouth Gulf Prawn Managed Fishery 3. Collect local environmental and productivity data to assess the feasibility of collecting broad scale data remotely. 4. Develop a cost effective monitoring program for critical fish habitat and environmental drivers which allows the development of mitigation measures to assist in alleviating poor recruitment events.

A key challenge therefore will be maintaining fishery productivity. Shark Bay and the Abrolhos Islands scallop fisheries are prime examples - following the extreme marine heat wave of 2011 lost income from these fisheries is estimated at $53 million GVP, or $155 million including multipliers.
The integration of aquaculture and wild fisheries is becoming increasingly recognised as a tool for enhancing fishery productivity (Taylor et al, 2017). Re-stocking and stock enhancement following recruitment failure could lead to faster fishery recoveries, and also be used to supplement natural recruitment to provide a more consistent and higher yield harvest from year to year. Development of supply chains for scallops into domestic and overseas high-value live markets requires consistent supply. Due to climatic variability and highly variable natural recruitment there is an urgent need to investigate scallop stock enhancement using hatchery-produced juveniles in WA.
A key element for success will be the development of reliable, efficient and scalable seed production systems, which will be based on previous research findings integrated novel, contemporary shellfish production technology. During this project, 16 million cultured scallop spat are planned to be released. The annual yield of scallops from the Rottnest SWF Zone A is 25 to 50 tonnes (whole scallop weight), or approximately 250,000 - 500,000 scallops assuming an average weight of 0.100 kg/whole scallop. This Project aims to release on average 8 million spat each year of the Project (600,000, 1,500,000 and 6,000,000 of 10mm, 5mm and 2mm spat respectively), which could contribute 45,000 hatchery-produced scallops to the catch each year assuming 2.50%, 1.00% and 0.25% of 10mm, 5mm and 2mm spat released respectively were captured, increasing yield by 8.3 – 16.6 % in the annual production, demonstrating the feasibility of scallop stock enhancement.
Objectives: 1. Develop and validate genetic tools to determine parentage / origin of scallops and measure genetic diversity 2. Develop hatchery and nursery protocols for consistent production of scallop spat 3. Develop strategies and methodologies for scallop spat deployment and stock enhancement sampling; measurement of seeded scallop spat survivorship; assessment of effect of spat size at deployment on survival rates; duration of growth to market size; determine impact of enhancement Read moreRead less
