This proposal represents an attempt to develop alternative technologies that would allow the prawn trawl industry to meet present and future strict environmental standards at a reduced operating cost. The proposal is not without risk, but reflects a genuine need to consider alternative fishing approaches outside the current thought envelope. If successful it would allow the industry to claim high environmental standards, meeting or exceeding the community expectations.
Alternatives to established fishery harvest methods are essential to meet ecologically sustainable development (ESD) requirements as dictated by international (UN) and national legislation (both federal and state) covering the marine environment. In recent years drift nets have been banned in many areas due to their detrimental impacts on non-targeted species and ecosystem structure. Similarly, ground trawling has been identified as a harvest technology that requires either restriction or banning due to its putative detrimental impacts on benthic ecosystems and disruption to food webs. Whereas drift net has been largely replaced by the sustainable and targeted method of hook and line harvesting, there are few alternatives to ground trawling.
Traps are used extensively for the harvesting of crustacea. Suitably designed pot traps can result in a minimum of by-catch and target individuals of specific size classes. However, pot trap fisheries utilise food as bait by which to attract the targeted species into the trap. Baited traps and pots are used for the commercial harvesting of pandalid prawns in the east Pacific and North Atlantic, where average catch/vessel/day of fishing effort is 80-110 kg. A smaller pot fishery exists for penaeid prawns in various parts of the Pacific basin and the Caribbean. However, attempts to date to develop a large pot trap fishery based on food bait for penaeid prawns have been largely unsuccessful.
It is proposed that chemical attractants, and not food bait, be examined as a means to harvest penaeid prawns in pots. The development of alternative harvest methods could form a non-trawl fishery with minimum by-catch, open up new areas to harvesting which are unsuitable for trawling, and produce a less stressful method to collect broodstock P. monodon prawns for the aquaculture sector as well as have spin-off potential for the development of pot trap fisheries for other species of crustacea.
1. 1. To quantify the attraction and specificity of pheromones from crustacea in experimental environments.
2. 2. To develop methods suitable for isolating and concentrating pheromones from crustacea, especially penaeid prawns.
3. 3. To identify a mechanism for manufacturing a bait incorporating these novel attractants.

Biofouling on pearl oysters, and the equipment used in culture of these oysters, is a major cost to the pearl industry throughout Australia. Rapid biofouling necessitates frequent cleaning, a process that is labour and capital intensive. The cost of cleaning, as estimated by the Pearl Produces Association, is approximately $15 to $20 per shell per year. The cost to the industry as a whole is likely to exceed $20 million/annum. Indirect costs include losses due to shell mortality, reduced growth rates and reduced pearl production from effects to nacre deposition.
Biofouling of oysters and equipment presents several problems if unattended. Invertebrates dominate fouling communities common to the pearl industry and these compete directly with pearl oysters for food. Several organisms, such as the sponge Cliona (red arse) and boring shellfish, directly attack the pearl oysters and result in shell damage or mortality. Excessive fouling of underwater surfaces also increases drag forces and increase the susceptibility of lines to storm damage. It is noteworthy that frequently cleaning is also problematic since evidence suggests that this type of handling reduces shell growth.
1. Production of efficacious antifouling coatings suitable for application to pearl oysters and pearl-culture equipment.
2. Testing of novel antifouling coatings across the geographic range of the pearling industry, with assessment of variation in fouling communities during the peak fouling seasons.
3. Development of methods suitable for routine application of antifouling coatings, to both shells and equipment, that can be successfully employed at pearling farms.
4. Identification of any effects to oyster growth, oyster health and the quality and production of pearls that result from use of efficacious antifouling products.

Rock Lobster Post Harvest Subprogram: optimising water quality in rock lobster post-harvest processes
Rock lobsters can be exposed to poor water quality during all stages of handling and holding prior to going to market. Poor water quality reduces the time a lobster can be held alive and how many animals can be held in a system and thus may reduce profit. The quality of water can be assessed using...

Globally risk assessment is becoming an important tool, used by industry and regulatory bodies. During the past decade a number of food safety risk assessments have been carried out including:
1994 Canada Listeria monocytogenes in pasteurised milk
1996 Canada various products
1997 USA Salmonella enteritidis in pasteurised eggs
1998 USA Ecoli O157:H7 in hamburger meat
1999 Australian dairy industry entire product range
1999 Australian meat industry various products
As HACCP based plans become more widely introduced it is becoming clear that there are serious limitations to applying HACCP in contexts where risk assessment has not been carried out.
The proposed seafood food safety risk assessment will separate the important few risks, from the many, by ranking products, processes and markets according to risk . Consequent risk communication followed by risk management actions will assist high risk sectors control their exposures.
The risk assessment and its outputs will enable the seafood industry and regulators to ensure that the food safety programs they develop and implement are soundly based on an assessment of risks in their business.
Recent successful litigation concerning food safety has further emphasised the importance of ensuring that due diligence has been followed in relation to managing food safety risks and that it is not enough to do what is required (by government) but to do what is necessary based on best available knowledge.
Phase 1 of the risk assessment has been completed. This project will complete phase 2 of the risk assessment and will produce a number of products which will help ensure that the seafood industry is operating within a soundly based food safety risk framework. One which is seen as ensuring credible food safety practices by industry, governments and importantly consumers.
This work is also essential as an input to the food safety standards for the seafood industry currently being developed by Seafood Services Australia.
1. Complete a comprehensive food safety risk assessment for the seafood industry in Australia.
2. Complete a compendium of hazards and controls for each species and process used by the seafood industry in Australia
3. Communicate the results of the risk assessment in forms appropriate to the needs of the stakeholders (including industry, government and customers)

A survey was made of all documented seafood-related illness for the period 1990-2000, when there were at least 2,638 who became ill after consuming seafood during the last decade, mainly after consuming oysters raw or eating fish known to be associated with ciguatera. The 2638 known illnesses represent a likelihood of illness every 6,000,000th meal. Allowing for 1% reporting of illness results in 263,800 illnesses over the decade and a likelihood of seafood causing illness increases in every 60,000th meal.
The prevalence of at-risk consumer groups was identified. Most of us have natural defences against food poisoning micro-organisms which first must survive the stomach acid before they can take up residence in our intestine. Unfortunately, for susceptible groups within the community, their natural defences are less effective and even small doses of bacteria or viruses can cause food poisoning. Around 20% of the Australian population has at least one at-risk factor, such as age, pregnancy, extreme youth, diabetes or cancer. At-risk consumers are especially vulnerable to certain hazards in seafoods.
Risk assessments were completed for ten hazard product pairings. Using a risk characterization tool, a Risk Ranking between 0 and 100 was estimated for each pairing.

To achieve the complementary outcomes of sustainability and economic benefits to the stakeholders in the SEF, a whole of chain approach to R&D is required (which is in accordance with government direction on R&D planning). Current practice focuses on the biology and fishery management which has precluded more innovative ways of adding value. Following a workshop held in November 1999 (Canberra) a recommendation was made that FRDC develop a subprogram to support the industry development component of R&D for the SEF. This application will develop the subprogram over the next year and produce a Strategic Plan that incorporates a whole of chain approach.
1. Coordinate the FRDC SEF subprogram (applications, workshops, communication)
2. Conduct an annual research workshop to present research outcomes from the subprogram and to define research objectives for subsequent years.
3. Facilitate travel of industry representatives and the subprogram leader to biannual steering committee meetings.
4. Coordinate the preparation of as subprogram newsletter, media releases, and workshop publications.
5. Integrate with other FRDC and externally funded SEF projects to ensure maximum leverage of industry funds and avoid duplication.

The bulk of the research that has been carried out for the South East Fishery (SEF) over the last decade has focussed on the collection of biological data, assessment of the status of fish stocks, research into the economics of the fishery, and the impact of fishing on the environment. In recent years, the need for a broader research and development (R&D) coverage to address whole of supply chain needs of the SEF has been recognised by Industry, AFMA, the Management Advisory Committees (MACs) and the Fisheries Research and Development Corporation. The SEF Industry Development Subprogram was established to help develop a whole of supply chain R&D strategy for the SEF and initiate new R&D projects to implement the strategy through increasing the value of SEF products by value-adding to fish products, adopting new technologies and improving utilisation of catches. To enable this, a Steering Committee of Industry representatives with expertise in the SEF whole of supply chain was formed to help foster and prioritise R&D into industry development areas. This report summarises the progress of the Subprogram over the first 18 months of operation to June 2001.
Two Subprogram meetings have been held. In the first, the role of the FRDC Subprogram and Steering Committee was outlined and the broad scope of the R&D strategy was developed. At the second meeting a range of pre-proposals were considered and we worked towards development of other projects that would fall within the scope of our priority R&D. We initially focused on two priority R&D areas: skills/training and fish waste utilisation. It was recognised that there was a need for skill development and training across the fishery’s supply chain, especially in areas such as product handling, food safety and OH&S issues. We are currently working with the relevant national and state seafood training bodies to plan and implement a training package relevant to the SEF. The significant level of fish wastes that are discarded by the industry from both the catching and processing sectors was another priority area. It was agreed to promote and support R&D that aimed to improve the utilisation of non-quota bycatch species by investigating suitable and cost-effective techniques to process the wide variety of discarded fish waste into products such as aquaculture feeds, silage, fish mince, fishmeal. Another waste minimisation option that is being explored is the use of value adding, improved promotion and targeted marketing campaigns to increase retention of certain low-value species that are usually discarded. Workshops to discuss training and waste utilisation R&D are planned for October 2001 with the aim of submitting a suite of related projects for funding by FRDC and other agencies.
The Subprogram’s first project entitled “The E-boat - implementation of an on-board electronic data collection and transmission system” began in May 2001. Jointly funded by AFFA and FRDC, the project is progressing well following an extensive phase of software development and modification to make it user-friendlier to the fishers. A working presentation of the software has been given at a number of venues and has received positive feedback from the industry groups. Work is progressing to enable the direct transfer of logbook data from fishers to AFMA to meet their SEF1 requirements. Trial data transfers have proceeded well and real data transfer is expected to take place early 2002. The potential for data from the E-boat software to directly feed into E-commerce sites, such as SFM-live, is being investigated.
Although slow to start, the Subprogram has achieved many of its initial objectives. The process of getting people together from across the whole of supply chain and networking has been valuable and is proving fruitful with respect to communication, advice and feedback from all sectors of the Industry. It is expected that within the next year or two, the full benefits of the development of the SEF Industry Development Subprogram should be realised with the initiation of a number of R&D projects under the umbrella of the Subprogram. The FRDC has supported a proposal to continue the Subprogram for a further two years from July 2001 to June 2003. After this time, the Steering Committee believes there should be a review of the progress of the Subprogram and the value of its future operation.
