Need

The Scientific Reference Group (SRG), including Drs Alistar Robertson, Simon Thrush, Andrew Heyward, John Keesing, Colin Buxton, Chris Simpson and Jim Penn, was formed as an independent body to provide advice on research directions, to examine the effects of western rock lobster fishing on the ecosystem. The SRG identified that there is a major gap in the understanding of the interactions between the rock lobster fishery and the ecosystem in deep water. Although significant data is available on the shallow (40 m) water ecology of lobsters and the fishing impact there is gap in the knowledge of the deep-water ecology of lobster. They recognised that the major change in abundance and size structure of the western rock lobster population would have occurred in deep water (40-100 m), and concluded this was a priority area of research. There is a need to collect basic ecological information to determine if changes in lobster density and size structure,due to fishing has caused significant changes in habitat structure and benthic community composition in deep water. This will provide information on the level of ecosystem impact of removing lobsters from deep-water habitats to improve the assessment of risk to the ecosystem to ensure that the western rock lobster fishery maintains MSC certification and complies with DEH requirements for export permits. However, the SRG recognised that research needs to occur in a structured manner and have highlighted the need for research proposals which sit within the strategic framework which they have devised. The SRG recognises that the provision of a strategic framework and related scientific research will ultimately allow management of deep-water stocks in a more sophisticated ecosystem-based manner.

Objectives

1. To identify gradients in the density/size distribution of western rock lobster to enable selection of representative areas.
2. To assess the catchability of western rock lobster and its relationship with population abundance and size structure
3. To identify the relationship between the deep-water habitat and the density/size distribution of western rock lobster to enable a preliminary evaluation of the impact of lobster biomass removal in the deep-water

Need

In 1999/2000 the estimated value of Australia’s rock lobster industry was $544 million and this represented 23% of the landed value of all Australian fisheries.

As Australia’s premier fisheries export there is a need to ensure that our lobster fisheries are managed sustainably and that they clearly demonstrate to the world that our research and management is ‘state-of-the-art’ and ‘worlds best practice’. By hosting this conference in Australia, it will enable the maximum number of fishery scientists, managers and industry representatives to attend and meet with scientists, managers and fishers associated with lobster fisheries around the world.

An area of particular interest to Australia includes lobster ecosystem models and assessment. There is a need in all of Australia’s lobster fisheries to address ecosystem issues for both Environment Australia and forthcoming ecological sustainable development requirements. In association with these requirements there is a need for Australia’s premier fisheries export industry to obtain and maintain industry accreditation for current and developing markets. Several Australian States, with the support of the FRDC Rock Lobster and Aquaculture Subprogram are investigating the potential for a rock lobster aquaculture industry. To aid this development there is a need to be abreast of the latest developments around the world.

The conference will also provide an opportunity to hear of the application of new technology and to form partnerships with experts pioneering new developments.

Objectives

1. To host the 7th International Conference and Workshop on Lobster Biology and Management in Hobart.
2. To publish the proceedings in a peer reviewed scientific journal

RESEARCH RELEVANCE AND ACCEPTANCE

FRDC is continually asked to fund a wide range of projects in the rock lobster post harvest area. These include studies of post-capture handling, transport, live holding cooking, packing, storing, freezing, Australian and international shipping, etc. To ensure that the investment in R&D results in significant profits for the industry it uses the Subprogram to assist it to measure the quality of science of the application, plan the research with industry partners to ensure improved outcomes, develop a comprehensive extension program, and ensure a high level of adoption of the results.

The Subprogram has achieved a high degree of research coordination between the States and an effective communication strategy to ensure service delivery to the industry. The Subprogram has added value to the FRDC's research investment by managing its project portfolio in this manner. This could not have been achieved without an independent Subprogram Leader and a highl responsive Steering Committee that is represented by industry members across Australia.

RESEARCH EFFICIENCY

Because of the Subprogram there have been substantive savings in the operation of projects and in the funding approved for new projects. The Subprogram ensures that the projects are appropriately costed, involves the industry in the projects where ever possible, and coordinates travel and workshop budjets to ensure a more efficient use of limited research funds.

NEW PROJECT DEVELOPMENT

As an indication of needs. The Subprogram is currently examining projects looking at:

1. Designing improved baskets for transporting both western and southern rock lobster lobsters. This project will be developed mainly with non FRDC funding.

Basket designs vary widely in the industry. The were developed add-hock all over different parts of the fisheries and all over Australia. In recent years there have been many modifictions to original designs as fishers attempted to transport ever increasing numbers of lobsters in a condition 'suitable for live export'. A better designed basket could provide financial savings to fishers and processors, and perhaps make them an interchangable item, similar to the use of wooden pallets in other industries. In addition, a better basket could assist with health and saftey issues, becuse many of the present baskets in use result in excessively heavy loads being carried, which may cause back damage.

2. Solving the “pink lobster” problem (2003/243)in western rock lobsters which is causing problems for both the wild fishery and processors.

Lobsters with pink flesh are difficult for processors to sell and the definiely get a reduced price. This is also a problem for fishers who, knowing of the processors problems, often tend to discsrd these lobsters at sea. It is mainly a western rock lobster problem but it does occur on a small scale in southern rock lobsters in SA.

3. Value adding the southern rock lobster catch by optimising flesh quality of uder valued large lobsters for the sashimi market (2003/242).

Large southern lobsters are difficult if not impossible to sell and if the are sold it is a very low prices. The possibility of value adding to these lobsters by 'preparing them' for the sashimi market is to be examined.

4. Production a booklet assisting sales of rock lobsters by advising overseas buyers how best to hold live rock lobsters; and documenting the operations of the market in Hong Kong for southern rock lobsters to assist Australian marketers from South Australia, Victoria and Tasmania.

5. The cooking project 2001/235 will lead to dramatic new projects after completing of this study. Progress in this project has impressed the industry and clearly indicated that significant improvements improvements can be made in this area. The cooking techniques in practice can greatly improved. Innovate methods such an microwave cooking will be investigated.

Other projects will be developed after identification and consultation with industry. In all cases the Subprogram seeks quality scientific studies using innovative approaches, with maximum cost effectiveness.

Objectives

1. Coordinate the FRDC Rock Lobster Post-Harvest Subprogram
2. Conduct an annual research workshop to present outcomes from the Subprogram to industry and the public, and to define research objectives for subsequent years
3. Facilitate travel of the Subprogram principal investigators, industry members and Subprogram Leader to biannual scientific committee meetings
4. Facilitate travel of industry members, and Subprogram leader to biannual Steering Committee meetings
5. Coordinate the preparation of Subprogram media releases and workshop publications
6. Integrate with other FRDC funded rock lobster research programs including the FRDC Enhancement and Aquaculture Subprogram
7. Coordinate the preparation and distribution of a biannual Subprogram newsletter
8. Develop and maintain a strategic plan for post-harvest rock lobster research
9. Continually supervise the scientific studies within the Subprogram

Summary

An independent Subprogram Leader, and a highly responsive Steering Committee, that is composed of industry experts from across Australia have provided an effective and efficient system for directing relevant research activities to ensure continued and increased profitability for the Australian rock lobster fisheries. The Steering Committee, under the Subprogram Leader’s direction, worked as an integrated group, rather than a collection of individuals, and carefully selected and recommended projects for funding, and then followed their progress and offered advice to principal investigators in the national interest. The industry representatives on the Steering Committee have also acted to provide research facilities within the industry as the best locations to conduct research, and ensuring the uptake of successful projects as soon as they occur.

The research conducted by the Subprogram has continued to significantly improved Australia’s understanding of the physiology and biochemistry of lobsters, from the time of capture through to processing in a variety of product forms. This is of considerable assistance in investigating methods of better handling, cooking, and/or processing lobsters for live export.

Need

In order for the industry to evaluate its performance in workplace accidents an industry driven system is required. The only available data at the moment is gained from fatalities and hearsay and it is extremely difficult to address areas of concern using this data. The industry must have its own reliable data to ensure appropriate insurance premium rates are established and the performance monitored by insurers is accurate.

In order for industry to establish priority areas, the collection of information is essential and presently none of the methods available meet industry requirements. This makes it impossible to monitor the performance of the industry due to the lack of useful data and doesn’t allow the industry to target areas with application to training courses and safety awareness sessions.

Objectives

1. Design and test a standard accident reporting system
2. Design and test a software system for data inputs and reports
3. Develop a mechanism for ensuring industry is trained in the use of the reporting process

Rock Lobster Enhancement and Aquaculture Subprogram: establishing post-pueruli growout data for western rock lobsters to assess economic viability

Need

Research has been completed showing that it is possible to harvest commercial quantities of pueruli/post-pueruli, which at this stage, appears to be unique in Australia. The same research has shown that harvesting of post-pueruli would have little impact on the commercial fishery and that there are ways of compensating the commercial catch to make post-pueruli removal biologically neutral. There is commercial interest in ongrowing western rock lobster post-pueruli to a marketable size, but basic data have yet to be obtained on growth and survival rates at different stocking densities. This project will provide the biological information (growth rates, food consumption etc) to assist potential investors in being able to assess the economic potential of this form of aquaculture. It should be noted that this proposed research will be equally relevant should it become possible in the future to produce pueruli by aquaculture, rather than by harvesting wild caught pureuli and post-pureuli.

Objectives

1. Determine optimal flow rates for pueruli and juvenile western rock lobsters held at high densities in flow through tanks.
2. Evaluation of growth rates and survival of pueruli to market sized lobsters with and without refuges and under two levels of biomass per unit volume of water.
3. Estimation of the expected survival rate and period required to produce a marketable size animal from post-puerulus.
4. Provide biological data to assist in assessing the economic potential for growing out western rock lobsters from post-puerulus to marketable size.
5. To determine the composition of lipids in cultured western rock lobsters compared to those of wild western rock lobsters of similar age and size.
6. To determine the influence of diet on the lipid composition of cultured western rock lobsters.

Need

Setose and maximum size rules have severely distorted the sex ratios and may have affected the sizes of mature (breeding) animals in the population. Research is necessary to investigate current and future projection of these management measures on fertilisation success in the breeding population.

To effectively manage the brood stock, it is important to have a knowledge of whether eggs from different regions in the fishery differ in ‘quality’ (i.e. would be likely to produce first stage larvae with different survival characteristics). This is particularly important for the Abrolhos Islands, which is estimated to contribute between 45-65% of egg production, but where the sizes of the eggs have previously been recorded as 10 to 15% smaller than at the coast. This project will assess whether the smaller eggs result in lower survival of stage 1 larvae, as an indicator of overall survival

At present no weighting is given to the contribution made by the three zones to egg production in the fishery. It is necessary to more fully understand the spatial distribution of the breeding stock in the zones when assessing effects of management packages.

Objectives

1. To investigate the biological implications of the setose and maximum size rules
2. To undertake preliminary investigations into the implications of egg diameters being significantly smaller at the Abrolhos Islands than at the coast
3. To quantify the extent of the breeding grounds, so as to weight the overall egg production index for the stock by the contribution of the management zones

Summary

Increases in efficiency due to modem electronic equipment, improved fishing vessels and knowledge about the grounds and lobster behaviour, have all led to western rock lobster fishers becoming more efficient at catching western rock lobsters in Western Australia. One of the outcomes of these increases in efficiency has been an increase in pressure on the breeding stock. Managers have responded by introducing measures to protect the breeders. In 1993, this involved the imposition of measures to limit the exploitation of mature female lobsters by introducing a legal maximum size for females as well as the protection of setose (mature) females.

The combination of high exploitation rates and protection of large, mature females, but not males, has since resulted in very distorted sex ratios of mature animals across the fishery, particularly those over the maximum size limit. It is well known from laboratory studies on other species of lobsters, that highly distorted female-dominated sex ratios (such as has been caused in the wild by the setose rule), and large females being forced through lack of choice to mate with small males (such as has been caused in the wild by both the setose and maximum size measures) can lead to sperm limitation effects (fertilisation of eggs but reduced brood sizes). These same management measures could have more positive effects - for instance in some species, the older individuals produce larger eggs, that in tum produce larger larvae that have been shown to have better survival characteristics.

These, and other unknowns, led to the initiation of this research project aimed at investigating these biological issues. The outputs from this research, together with other data, provide an indication of the contribution to egg production of different management zones in the western rock lobster commercial fishery.

Summary

Perth, Western Australia was the Host State for the third Seafood Directions Conference. The conference is held bi annually and is the premier conference for members and associated parties of the seafood industry. The conference was previously held in Brisbane (2001) and Adelaide (1999), Sydney will host the conference in 2005.

The Rock Lobster Congress 3 hosted by the Western Rock Lobster Council was held on Tuesday 16 September prior to Seafood Directions for the first time.  By holding the congress prior to the conference encouraged attendance by fisherman at Seafood Directions 2003, and this was a delegate base the conference was keen to have attend.

The Women’s Industry Network Seafood Community Conference was a one-day conference held on Wednesday 17 September.  The organising committee believed it was of importance to incorporate this conference into Seafood Directions and also offered a discounted rate to WINSC delegates to attend Seafood Directions on the Thursday.
