Need

This project is focused on improving industry and government preparedness to respond to nationally significant exotic disease outbreaks and in doing so, protect or minimise the impacts of exotic diseases on profitability and productivity. There are national preparedness arrangements in place however (fortunately) many of these have yet to be used in a real-world response, including the AQUAVETPLAN response manuals which outline technical response arrangements and the draft Aquatic Deed which outlines how costs and managing emergency responses will be shared among industry and government. Prospective parties are currently considering whether they will ratify the draft Aquatic Deed. This project is not dependent on whether the deed is ratified and can be adapted to the circumstances of existing response arrangements.

This project addresses the need to test existing contingency planning arrangements for some nationally important exotic diseases to increase shared understanding among industry and governments of their responsibilities and capabilities that they can bring to a response. The main objective is to test arrangements and identify any gaps in peace time for how a response can be undertaken most cost effectively. For governments, this includes understanding operational aspects of industry including assets that could be used for a response. For industry, it includes understanding any gaps in preparedness in particular operational gaps and identifying where and how they could be addressed in peace time.

Scenario-based discussion exercises are a cost-effective way of validating the procedures or processes and are valuable for building the knowledge and preparedness of participating organisations (governments and industry). Conducting a series of exercises based on existing contingency arrangements will contribute to closing the gaps between current capability and current needs and improve levels of preparedness for priority exotic diseases.

Objectives

1. To test that technical response arrangements are fit for purpose and include sufficient practical information for use in a response.
2. Gaps in preparedness or areas of difficulty in responding to a disease outbreak are identified and solutions found without the pressure of a real-world response
3. Promote a common understanding among industry and government about roles, responsibilities and expectations during an emergency response, including at a farm, state and national level.

Need

Achieving the mandated dose rate of 50 kGy for prawns harvested from the White Spot Disease control zone in SE QLD is proving to be problematic and industry are requesting a reduction in the permitted irradiation dose rate for prawns sourced from Moreton Bay to somewhere between 15 and 25 kGy. A reduction in treatment dose, if successful, would provide a viable option for industry to continue trade in uncooked prawns sourced from Moreton Bay.

There appears to be only three scientific papers relevant to the subject of using gamma irradiation for inactivation of WSSV (Heidareh et al. 2014, Kakoolaki et al. 2015, Motamedi-Sedeh et al. 2017). The studies were conducted with the aim of determining the doses required to inactivate the Iranian isolate of WSSV with gamma irradiation for the purposes of vaccinating cultured prawns. While the listed scientific papers suggest gamma irradiation at a dose of around 13-15 kGy is effective at inactivating WSSV, their experimental protocols and results are not clearly transferable. In these studies aliquots of free virus were exposed to different gamma irradiation doses. Irradiation of WSSV inside infected host tissues was not performed, and data on whether the surviving prawns were infected with WSSV were not presented. None of these papers are therefore directly applicable to the situation relating to irradiation treatment of WSSV in-situ inside infected prawns.

Given the absence of information on irradiation doses for inactivation of WSSV in the Department of Agriculture (2014) review document, and the absence of research in Australia or overseas to validate alternative irradiation doses that completely inactivate WSSV, new research is urgently required to determine the minimum safe irradiation dose for inactivation of WSSV in prawns with the results verified by controlled challenge trials in a bio-secure facility.

Objectives

1. To determine minimal effective dose of gamma irradiation to render WSSV non-infectious in prawns.

Summary

White spot syndrome virus (WSSV) was detected in diseased farmed prawns by Biosecurity Queensland’s Biological  Sciences  Laboratory  and  confirmed  by  the  CSIRO  Australian  Centre  for  Diagnostic  Preparedness (ACDP) Fish Diseases Laboratory in November/December 2016. This exotic aquatic disease incursion resulted in the infection of all prawn farms, under production, along the Logan River, Queensland. Subsequent WSSV detections in prawns and crabs in northern Moreton Bay resulted in the issuing of a Movement Control Order and  subsequent  WSSV  biosecurity control order  under  the  Biosecurity  Act  2014,  which  prohibited  the movement of potential carriers (e.g. polychaete worms and decapod crustaceans) from Moreton Bay. These restrictions  included  wild  caught  prawns  from  Moreton  Bay  which  were  distributed  nationally  as  bait  for recreational  fishing.  Industry  established  protocols  to  treat  these  prawns,  for  distribution  as  bait,  using gamma  irradiation to  a  dose  of  50 kilogray (kGy).  However,  this  treatment  understandably  resulted  in increased costs of the final product, raising concerns that this would make imported commodity prawns a more likely source of bait for recreational fishing and consequently a biosecurity risk for introduction of exotic diseases.
 
The  primary  objective  of  this  project  was  to  determine whether gamma  irradiation treatment of WSSV infected prawns at a dose lower than 50 kGy would inactivate the virus as the bait wholesale industry indicated that a reduction in treatment dose to 25 kGy or lower would be required to provide meaningful cost benefits. Given  the  absence  of  information  on  irradiation  doses  for inactivation  of  WSSV, this collaborative project involving Department of Agriculture and Fisheries, Queensland, CSIRO ACDP, Steritech and industry, conducted research to evaluate the effect of reduced doses of gamma irradiation (10 kGy, 15 kGy, 20 kGy and 25 kGy) on inactivation of WSSV in infected prawns. 

Love Australian Prawns evaluation using consumer research, sales data and market insights

Project number: 2016-272
Project Status:
Completed

Need

Consumer research and sales data analysis needs to be acquired and reviewed alongside Love Australian Prawns campaign strategies. The information is required as part of monitoring and evaluation, which is an RD&E activity, as set out in the initial campaign. This information then needs to be reviewed against past LAP outputs and proposed future activities in advance of commissioning work for Year 5. This review could also advise likely fit with a proposed national seafood marketing campaign and the lifespan of the Love Australian Prawns campaign.

LAP contributors are looking to verify their return on investment in LAP. New contributors, such as NSW, Qld and Vic also require this information as they decide to invest.

This proposal also flags activities that the LAP Committee propose meet R,D & E criteria rather than Marketing. These were proposed in September 2016 and LAP interest confirmed following the review of LAP.

Objectives

1. Love Australian Prawns campaign monitored, evaluated and planned for 2017 and beyond
2. Number of LAP financial contributors increased for Year 5

Summary

Having commissioned Brand Council to review Love Australian Prawns (LAP) strategy and outputs and the University of Sunshine Coast to compare LAP consumer perception and awareness to previous years, the Australian Council of Prawn Fisheries Ltd (ACPF) and the Australian Prawn Farmers’ Association (APFA) have ascertained that LAP is achieving its original objectives. 1 in 5 Australians now recognize the LAP logo: this sort of awareness usually only achieved via TV campaigns. The industry has experienced an average 20% increase in Medium, Med-Large and Large grades between the start of the LAP campaign until the end of 2016 with statements of recognition from the industry that “You would expect some of this demand can be attributed to the Love Australian Prawns campaign."

Results/key findings
The original objectives for LAP have been achieved through four years of LAP. This was particularly demonstrated through consumer research.
Objectives achieved.
  1. Increasing desire for/ desirability of Australian prawns. Example USC evidence: 38% of consumers report they are eating more prawns than 3 years ago with those consumers being more likely to recognise the LAP logo when they see it
  2. Australian prawns special place Aust eating habits. Example USC evidence: 20% of Australians are still buying prawns for the traditional special occasions such as Christmas and Easter but 25% are now buying prawns for a special occasion or a treat through the year. Over 50% are eating prawns with the family in a meal at home.
  3. Increase value of Australian prawn. Example industry sales data evidence: 20% price increases on average across Med to Large grades between the start of the LAP campaign until now. Some fisheries reported that 20% price increase for larger grades in the 2016/17 year alone, despite having more supply than in past years

Implications for relevant stakeholders
The implications of this work are directed at industry as investors in LAP. Industry contributors and LAP need to be aware of;

  • Despite only having approximately 50% of the total potential industry funded marketing budget at its disposal, LAP has achieved its objectives.
  • In order to maintain the differentiation of Australian prawns in the marketplace, LAP must continue to run as along as possible
  • In a competitive market the LAP campaign’s front-line content must continue to focus on positioning Australian prawns as special rather than on education
  • The continued dominance of supermarkets for prawn sales confirms that LAP needs to cost effectively increase LAP brand presence in major supermarkets
  • Without a compulsory marketing levy, communication of campaign achievements along with future consumer research results will be needed to increase industry contribution.

Recommendations
The following recommendations stem from the implications of the evaluation and monitoring of LAP.

  1. Subject to the ongoing support and agreement of contributors, the LAP campaign continue, in order to retain consumer awareness of and desirability for Australian prawns differentiated from imported prawns
  2. Future LAP campaigns retain the same focus as agreed at the conception of the campaign ie to make prawns ‘special’ (celebrated, occasion, real, nurturing families and friends – positioning away from convenience and ordinary every day)
  3. To protect the brand, all LAP produced items should reflect the ‘special’ positioning and the promotional focus of LAP, being careful to properly prioritise retailer needs
  4. The LAP campaign’s front line content to focus on position rather than education.
  5. LAP MC to review materials required for 2018-19 onwards that is required to add to LAP appeal eg need for further consumption scenario photography such as friends eating prawns at Christmas in July, Mothers Day, etc to add to LAP’s footage
  6. The MC instigate 2017-18 initiatives to cost effectively support seafood retailers and supermarkets with collateral to feature the LAP brand, including through appropriate partnerships
  7. The LAP MC continue initiatives to spread peak special occasion consumption periods through the year as has proven effective
  8. The LAP MC continue to measure campaign effects through RD&E funded-commissioned consumer research, including with the University of Sunshine Coast on a regular basis so that previous existing datasets can be accessed.
  9. If possible, obtain sales data using RD&E funds via arrangement with FRDC and Nielsens to at least identify changes in volumes between Australian and imported prawns over time
  10. The LAP MC continue to communicate campaign achievements
