Need

The need for further information to assist with the response to OsHV-1 is universally acknowledged by the aquaculture industry broadly, government agencies charged with biosecurity and aquatic animal health scientists in Australia and internationally.
Access to a standardised, reproducible and transferable laboratory infection model is critical to ongoing research efforts. Such a model provides a precise method of testing the effect of factors which are suspected to influence the outcome of an infectious challenge with OsHV-1 on Pacific oysters. The most promising factor for enabling continuation of Pacific oyster production despite the threat of OsHV-1 infection is the identification of genetic variation in susceptibility to POMS. The demand for efficient progress in selective breeding programmes requires a laboratory infection model which is suitable for screening large numbers of candidate families and provides results which can be reliably interpreted.

Objectives

1. Production and long-term storage of large quantities of a standard OsHV-1 inoculum
2. Evaluation of methods to provide a standard, measured OsHV-1 infection challenge
3. Definition of the outcomes of infectious challenge including mortality, development of histopathological lesions and quantities of OsHV-1 present in tissues
4. Determination of the dose-response under standardised challenge conditions, including variation due to the age of the oysters
5. Determination of the repeatability, reproducibility and transferability of the standard infection challenge
6. Assessment of the susceptibility of flat oysters (spat and adult) to OsHV-1 infection.

Need

In Australia, > 1500 vessels are endorsed to target prawns off nearly all coastal states and territories. While some vessels are single-rigged, most use multi-net systems; the application of which is based on the preferential use of configurations that were in place when fisheries were first defined by legislation or, more recently, introduced to control effort based on unsubstantiated perceptions about relative efficiencies.

Although considerable effort has been directed towards reducing bycatch via posterior gear modifications, very little science has been done to assess changes to anterior configurations, despite the acknowledgement of clear differences in drag and preliminary evidence of variations in selectivity and habitat impacts. It is highly likely that, within the current range of anterior trawl configurations used in Australia, there exist optimal combinations, with particular ground gears, materials and otter boards that could significantly address the sustainability issues common among all trawl fisheries.

Beyond conventional trawl systems are new, potentially more efficient and lower impacting components, including refined otter boards such as the ‘batwing’. Such research is in its infancy, but nevertheless important because otter boards are likely to have varying impacts on the seabed and the target and bycatches; especially considering that many designs can represent more than 20% of the total area swept by the gear. Other simple anterior modifications may include acoustic deterrents (to scare fish away), larger and/or lighter meshes, and less intrusive ground gears. Applied individually, or in combination, such modifications could dramatically reduce bycatches, with many reducing seabed impacts and lowering drag.

The utility of anterior gear modifications needs to be assessed and prioritized to provide a coherent basis for future research, not only in NSW, but throughout Australia’s prawn-trawl fisheries. This strategy fits in with proven approaches for developing modifications to posterior sections and changes to operations and onboard handling.

Objectives

1. To identify anterior gear modifications that reduce the bycatch, drag and habitat impacts of prawn trawls, while maintaining target catches and isolate their mechanisms of action.
2. Using (i) above, provide a framework and direction for the future refinement of Australian prawn trawls.
3. Investigate the practicality of simple, but appropriate changes identified above under commercial conditions in NSW, and assist this state's fishers and managers in their implementation, adoption and where appropriate, eventual legislation.

Summary

This project is among the first of its kind for any Australian fishery, and indeed for any prawn (or shrimp) fishery worldwide. The work represents a four-year (from September 2011) collaborative effort between the New South Wales (NSW) fishing industry and the NSW Department of Primary Industries, Sterling Trawl Gear Services and the Australian Maritime College. This collaboration ultimately sought to provide a first step towards developing applied technological solutions to holistically mitigate key sustainability issues facing prawn-trawl fisheries. The holistic environment was achieved by adopting an eco-efficiency approach to the assessment of issues. The work mostly was concentrated in NSW, but the results have national and international application.
 
The aims of this four-year project were to:
(1) identify anterior gear modifications that reduce the bycatch, fuel consumption and habitat impacts of prawn trawls, while maintaining target catches, and isolate their mechanisms of action;
(2) using this information, provide a framework and direction for the future refinement of Australian prawn trawls; and
(3) investigate the practicality of simple, but appropriate changes identified above under commercial conditions in NSW, and assist this state's fishers and managers in their implementation, adoption and where appropriate, eventual legislation.
Ultimately, the collective objective of the work was to provide clear direction for ongoing strategic fishing-gear research to improve the social and economic benefits of Australian prawn-trawl fisheries, while reducing their environmental footprint.

Need

World-wide, shark fisheries are reputedly unsustainable. The NPOA Sharks and IUCN list over-fishing as a major threat to Australian shark populations. In NSW, the OTLF catches most sharks. Both the FMS and EIS recognise this component as requiring urgent research due to the perceived high risk to targeted whaler sharks resulting from their known low fecundity and resultant susceptibility to over-fishing.

The OTLMAC and NSW SIAC reiterated concern following the rapid expansion of the large shark fishery during the mid-2000s. The impact of this expansion on the so-called ‘historical shark fishers’ was queried.
Recently, an independent review by CSIRO on behalf of DEWHA highlighted the lack of knowledge to effectively manage this fishery. Subsequently, a new overtly precautionary TAC was determined. This reduced TAC has the potential to negatively affect regional socio-economics. Data enabling a viable and sustainable shark fin fishery, while supporting the conditions for EPBC Act WTOs, are urgently required.

Significant investment by I&I NSW is providing data on shark species composition, their biology, fishing gear details, and spatio-temporal catch information. Although these data will substantially contribute to enabling suitable management protocols, I&I NSW fisheries managers have called for more information on:
(1) stock structure and effective population size to enable sustainable TACs to be set; (2) methods to reduce unwanted catch thereby minimizing environmental impact; (3) movements of target species to enable equitable State-wide access to the resource for fishers while providing temporal-spatial management options to improve risk-management of this fishery.

Considering the OTLF catch levels and historical collapse of other fisheries internationally targeting dusky and sandbar sharks, I&I NSW fisheries managers have requested particular focus on these two whaler shark species. This proposal aims to address the management needs through innovative new techniques utilizing linkages with several laboratories, national research programs and management agencies.

Objectives

1. Genetically resolve the effective population size of dusky and sandbar sharks targeted in the OTLF
2. Determine the short-term and distance movements of sandbar and dusky sharks to assist in the development of potential spatial management options like time-area (spatio-temporal) closures
3. Develop a fishing technique that will decrease mortality of unwanted species, particularly threatened and protected species, to minimize environmental impact of the fishery
4. Assess the effectiveness of the I&I NSW shark field ID-guide through ground-truthing on-board shark identification between fishers and observers, plus via genetic testing
5. Evaluate assessment methods and management indicators for the main shark species that may provide a model for future national and/or international data-poor shark fisheries
6. Apply assessment methods and management indicators for data-poor species that may provide a model for future national and/or international data-poor shark fisheries.
7. Provide scientific data-based advice for management to ensure the future sustainability of shark populations.

Summary

New South Wales Department of Primary Industries (NSW DPI) presents new information exploring the shark catch of the NSW Ocean Trap & Line Fishery and developing methods to ensure an accurately reported, sustainable and profitable fishery for large sharks is maintained.
 
A combination of novel genetic techniques, extensive field work, and numerical modelling was undertaken during this FRDC Shark Futures project.
 
This allowed development of an innovative way to bring together genetic and demographic data for estimating population size and modelling sustainable catch levels for target species. Identification of shark species has historically been problematic with many species lumped into similar groups in historical catch logbooks. The new NSW catch logbooks differentiate between shark species caught in commercial fisheries and a corresponding shark identification guide provided to fishers. We assess the effectiveness of this guidebook in providing accurate catch reporting and determine the minimum data required to be collected to enable fisheries managers and compliance officers to effectively regulate a large shark fishery. As management options have often included a trip limit of total allowable catch, we investigated the fate of sharks caught on demersal longlines and model factors affecting their post-release survivorship. This is particularly pertinent for non-selective fishing gear such as demersal longlines which hook species of conservation value and other bycatch as part of their normal fishing operations. Finally, we also assess the levels of metals and metalloids in shark product sold from this fishery to determine whether there could be any negative health implications for human consumers. Excessive levels of mercury and arsenic were detected and suggestions subsequently made on how to ensure product from NSW large shark fisheries are kept within the standards of Food Standards Australia New Zealand.

Need

Within the Seafood CRC, approximately half the industry participants have committed most of their contribution to the CRC for production-based research and the majority of research provider participants are involved with production research. In total, approximately $3.5 million p.a. has been committed to finfish production or genetic research. While many participants have already committed to projects to address their priorities, the level of collaboration within these projects is modest and, as the majority of projects will conclude within 2-3 years, industry and research participants have expressed a desire to increase collaboration and networking. There is therefore an opportunity to better exploit synergies between industry and research participants to improve delivery of planned outcomes. Within the aquaculture industry, including sectors and companies outside the Seafood CRC, there is a strong need to increase the overall level of technology. In many cases, organisations have difficulty accessing the latest successful technology, particularly in the hatchery sector. This needs to be addressed through better networking and information exchange.

Specific needs are:
• To develop new levels of collaboration and cooperation across aquaculture sectors, disciplines and CRC programs and projects
• To coordinate training and capacity building programs for industry and research participants (including within and outside the CRC)
• To improve efficiency of project initiation and delivery of research outcomes
• To plan and budget activities to achieve target industry outcomes
• To generate investment in strategic research focused CRC outcomes
• Create mechanisms and cooperative research systems which can outlive the CRC

Objectives

1. Increase communication and collaboration among industry and research participants
2. Identify priorities and help develop applied research, training and extension activities

Summary

The Aquaculture Innovation Hub was a new initiative from the Seafood CRC and the Fisheries Research and Development Corporation to coordinate aquaculture research under the Seafood CRC, facilitate improved communication and assist development of new collaborative projects.

The hub brought together industry participants and research providers and fostered a better understanding of the research challenges faced by industry and the capacity and potential for researchers to address these challenges. The hub arranged face-to-face meetings, established a website and put help people stay in touch through email, teleconferences, text messaging and other forms of communication.

In addition, the hub developed and managed two hatchery networks, one for shellfish and one for marine finfish. The aim of the networks was to help hatcheries access and adopt the latest technology and identify key research, training and education priorities. The networks helped coordinate specific sessions on hatchery technology at the Australasian Aquaculture conferences in 2010 and 2012. Vocational and academic training needs were identified and training workshops, technical exchanges and visits organised.

Need

The regional veterinary laboratory at EMAI (RVL Menangle) has in the last 2 months employed four full time trainee veterinary pathologists from Consolidated Revenue - thus, a long term committment to state based diagnostics has been made. Additionally, I have been employed in a full time capacity as diagnostic pathologist and laboratory leader. Our status with regards to terrestrial animal diagnostics is excellent, and we have some significant depth. My concern is that as our aquatic diagnostic load begins to increase, our trainees will lack the depth of knowlege required to advise industry.

Dr Judith Handlinger is willing to spend one week with the four trainees, specifically teaching finfish, crustacean and bivalve pathology and diagnostics. In return, I will spend one week in the DPI Tasmania lab giving a course to their four new pathologists on general pathological principles.

This modest project would expose a new generation of diagnosticians to a soon to be retired world expert, and foster increased collegial relationships between two laboratories that have a significant role to play in the Australia Aquatic industries.

Objectives

1. Increased knowledge of basic aquatic physiology and immunology
2. Increased knowledge of common aquatic pathological responses
3. In depth gross examination of the diseased specimen
4. Histological diagnosis of common disease affecting Australian aquaculture species
5. General diagnostics and warning signs regarding exotic aquaculture diseases
6. Professional networking amongst two significant aquaculture diagnostic centers.

Need

Inland fish stocking programs in NSW are administered by NSW DPI under the NSW Freshwater Fish Stocking Fishery Management Strategy (FMS) which outlines the rules, regulations and programs for fish stocking. The FMS is due for review in the near future and it is an opportune time to investigate the strategies used by international agencies for the management of their stocking programs. An extensive worldwide network of scientists and fisheries managers will be in attendance at the FSBI conference in Hull and it will be most beneficial to gain exposure on an international scale, obtain up to date information and share perspectives on inland fisheries management with experts from international agencies. In addition to attendance at the conference, I have made contact with several staff members from the Environment Agency and the Angling Trust to gain further insights into the management of inland fish stocking programs in the UK. I have organised to meet with these experts at various locations including Brampton, Reading and Frimley outside of the conference to gain further exposure and directly observe management practices and perceptions from both Government and non-Government organisations which may be transferable to existing NSW programs and other Australian jurisdictions developing or refining stocking policies. The project will assist in bridging the gap between management and research by potentially identifying key research priorities for stocking programs. The project will importantly enhance my international presentation, networking and analysis skills which are essential for my development as a future leader in fisheries management.

Objectives

1. To provide a presentation and receive feedback from an international audience on the management of NSW freshwater fish stocking programs and assessment process.
2. To network with other fisheries managers and researchers.
3. To gain knowledge from international fisheries managers to apply to NSW stocking programs.
4. To add to my personal development and leadership skills through the above objectives.

Need

My project investigates rec fisher catch, harvest and effort for Murray cod, golden perch and Murray crayfish using survey methodologies. I am also investigating length and age at maturity for Murray cod and golden perch to assess existing minimum legal lengths, and also using calcein marked hatchery reared Murray cod to assess the effectiveness of stocking this species. I plan to present some of my results, most likely from the fisher survey, to the American fisheries society at their annual conference where I will gain exposure to other experts in this field and share my knowledge and findings with other researchers. In addition to the conference attendance I will also spend time with either Mark Allen who researches striped bass (which correlates closely with Murray cod), or ken pollock, who is a global authority with fisher surveys.

Objectives

1. To network with other researchers at an international conference
2. To learn from industry leaders and incorporate this new knowledge to NSW fisheries
3. To present my findings at the international level

Need

There is a growing need not only to assess recreational fisheries throughout Australia, but to undertake these assessments in a cost-effective manner and produce deliverables that management and the recreational fishing community can readily adopt. The National Recreational and Indigenous Fishing Survey was undertaken in 2000-2001, and since this survey, most fisheries agencies have been grappling with how to complete robust and cost-effective surveys within their jurisdiction. There is a strong need for greater collaboration among scientists, managers and stakeholders from the different jurisdictions, to review and critique existing and new methods so that future surveys produce better outcomes at lower costs.

ASFB workshops have been held each year since 1985. The 2008 ASFB workshop is an ideal and timely opportunity for researchers, managers, students and stakeholders to cooperatively critique and strategically develop a framework for testing methodologies and designing assessments of recreational fisheries throughout Australia.

Objectives

1. The broad objective of the workshop is to discuss and develop robust, cost-effective and comparative methodologies to assess recreational fisheries throughout Australia. Specific objectives include:
2. review existing approaches
3. critique new approaches
4. develop a framework for assessing recreational fisheries in Australia.
