Developing case ready retail and bulk catering pack for seafood using M.A.P technology
We have been advised of strategic business plans by supermarkets as to how the retail sector will position itself within the next few years. In-house re-packing operations, such as those currently evidenced in supermarket meat, seafood and deli departments, will eventually be non -existent with retailers seeking to out source case-ready products offering extended shelf life, a greater choice, and a reduction in food-related health hazards. The health hazard issue is seen as a real concern within these supermarket departments.
As a leading seafood processor in Western Australia we have a need to position our company in readiness for this major change. Seafood is one of the last fresh protein items to be packaged in a MAP format for retail supermarket sale. Retailers have seen significant changes and growth in the presentation of red meat and poultry in the MAP format and are keen for seafood processors to develop the MAP technology. In the UK for example, since the mid 80's, 80% of case-ready seafood for retail supermarkets is presented in the MAP format.
MAP of seafood in Australia is still in its infancy and to our knowledge there are only 2 companies exploring the use of MAP technology for seafood. Whilst there has been some research on MAP for Australian seafood, little work has been done on WA species. There has been no evaluation of benefits of MAP against the costs, yet this is the fundamental for commercialisation of the technology.
There is also a need to develop bulk packs of seafood for the domestic and export markets. The use of this technology on fresh fish for the Singapore market in particular, can possibily open up new markets. Our company is currently exporting chilled fish such as Snapper, Threadfin Bream, Flag-fish, Blue Spot Emperor, and Swordfish to Singapore and we believe there may be potential to develop new markets if the shelf life is extended using the MAP format. We clearly need to evaluate what benefits can be achieved and what new products and markets can be developed. Furthermore, we have been working with a company in Sydney who has developed a new electronic marketing strategy for seafood by way of Internet Marketing and direct delivery to consumers and commercial accounts. (The company can be viewed on the Internet - www.greengrocer.com.au). We currently supply Greengrocer.com quality hand selected, dry filleted, individually wrapped fillets, which are specially processed and trimmed. This type of presentation commands a higher return.
We believe there is good potential for this type of premium product marketed by e-commerce if the shelf life can be extended to enable greater distribution throughout Australia.
Final report
The project focussed on determining initial fish quality for MAP process and initial chemical treatments to lower microbiological loads on raw materials used, the evaluation of various species in at least one gas mixture against controls and also to determine programs for further evaluation.
Aquatic Animal Health Subprogram: the revision of the Tasmanian fish health plan and incorporation into the Tasmanian control centre manual
There is a need to train industry in disease control strategies that will also contribute to the effectiveness of emergency control activities. The areas where this will have greatest impact are field activities and industry liaison. There is also a need to train existing government agencies skilled in areas of emergency response to effectively respond to aquatic animal diseases.
Field activities are determined by the cause of the emergency, species involved and the communities affected. Considering Tasmania’s population and accompanying financial constraints there is a need for emergency response personnel to be trained and available for action in both terrestrial and aquatic environments.

SCRC: Seafood CRC: ‘WERA’ Industry Bursary 2008
This subject was suggested as an education and training priority at the Oyster Consortium meeting in Sydney March’07, was reaffirmed at the Oyster Consortium planning meeting in Hobart in September 07, and was broached again at the Shellfish Futures Conference in Hobart, Nov 07. Whilst Roy Palmer was in Rhode Island (on other business) he had a meeting with the Chair of WERA and obtained information which he put into a report that was circulated to the Oyster Consortium.
WERA objectives are
1. Provide a forum for geneticists, physiologists, nutritionists, biotechnologists and others interested in the aquaculture of molluscan shellfish to exchange ideas and information on molluscan genetics, reproduction, pathology, brood-stock management, breeding programs, hatcheries, husbandry techniques, and restoration strategies.
2. Develop protocols for the preservation of valuable genetic material for future use by researchers.
3. Maximise and co-ordinate research efforts among scientists on the Pacific, Atlantic and Gulf coasts, USA, as well as international researchers.
4. Identify research needs for enhancement of commercial molluscan production through genetic improvement while maintaining environmental quality.
5. Evaluate different approaches for restoration of depleted stocks of native oysters.
6. Provide industry members with up-to-date research information that will lead to optimal brood-stock management and breeding programs to enhance commercial production.
7. Publish committee reports and documents.
Final report
Judd Evans and I attended the WERA 099 Broodstock Management, Genetics and Breeding Programs for Molluscan Shellfish meeting on Sunday the 6th of April and the National Shellfish Association Annual Conference, 6th to 10th of April, held in Providence, Rhode Island. We then travelled, via New York, to Newport, Oregon (the Hatfield marine Research Centre) and up to Shelton, Washington (Taylors’ Shellfish) visiting an oyster farm and a hatchery along the way. We returned home on the 18th of April. The following is a report, in diary form, of this trip.
Diagnosis and prevention of the mid-crop mortality syndrome of pond-reared black tiger prawns (Penaeus monodon)
Final report
The project has created knowledge which has led to the outcome of better health management on Australian prawn farms. Changes to farm practices have occurred where whole-farm destocking and pond disinfection are applied as a hygiene practice following a season where crop declines or failures are seen. During, and subsequent to, the project prawn farmers now understand that infectious disease can affect cultured marine prawns in earthen ponds. As a consequence many farmers will submit sick prawns for diagnostic analysis soon after stressed prawns are seen in ponds, not assuming the problems are due to pond environment factors.
The project has contributed to the recovery of the Queensland prawn farm industry from the low production seen in the 1995/96 season of 1,294 tonnes (worth $28.2m) to 1855 tonnes (worth $32.4m) reported in 1998/99. A similar outcome is reflected when Australian marine prawn production is considered; from a low of 1,400 tonnes in 1994/95 to 2,059 tonnes of production in 1997/98.
The project has shown that a virus associated with Mid-Crop Mortality Syndrome is passed from breeders to their progeny. The project has created the knowledge of a detection test and that application of that test can be used by hatcheries to reduce the effect of the virus on productivity in the hatchery and farms.
