Seafood CRC: Australian Council of Prawn Fisheries (ACPF) Strategic Plan and Business Plan
Seafood CRC: a new refrigeration system reference design and demonstration prototype for fishing vessels
Seafood CRC: addressing roadblocks to the adoption of economics in fisheries policy (2013/748.20 Communal)
Producing peer-reviewed publication on these topics is part of the suite of approaches aimed at increasing uptake of FH projects. Scientific papers enable exchange of ideas internationally. They are part of the process of changing fishery management which needs these types of outputs to defend decisions.
Final report
This project has led to the development of three journal articles examining how the use of economic analyses and stock enhancement can lead to improved economic outcomes in Australian wild-capture commercial fisheries. The Seafood Cooperative Research Centre (Seafood CRC) Future Harvest (FH) projects identified some of the challenges and opportunities associated with implementing bio-economic approaches and stock enhancement within fisheries management frameworks. Much of this discourse was contained however in technical reports, newsletters and other project-linked documentation (e.g. milestone reports). Thus there was a need (and space) to document the adoption of bio-economics and stock enhancement within fisheries management frameworks, associated challenges and the process of change management in Australian fisheries within peer-reviewed journal articles.
Seafood CRC: a best practice protocol and methodology for economic data collection in Australian fisheries
Developing basic frameworks for the collection and reporting of fisheries economic data is necessary to
i) provide input into planned future versions of the national fisheries status report and
ii) at the state level, support the MEY-based approaches and associated target reference points that are increasingly being incorporated in fisheries management plans and harvest strategies.
Revitalising estuaries and wetlands for carbon sequestration, biodiversity, fisheries and the community
Business as usual has caused the problem we seek to address. Australian estuaries and wetlands have been under-valued and much of their ecological function has been lost due to a multitude of small, past decisions coupled with a lack of understanding of their importance and community benefits.
Connectivity loss is an issue across Australia - eg road bridges, causeways, tidal barrages, culverts, ponded pastures, bund walls. As an example, GBRMPA has mapped in excess of 1500 barriers to fish passage just in the Burdekin catchment.
These various barriers have been constructed in times past when knowledge was lacking. We now as a community appreciate the many values of coastal ecosystems and generally the community supports their repair as a means of addressing the legacy of past decisions.
At the same time, a note of caution is necessary. in many cases there has been irrevocable loss. The art form in this Australia-wide Plan will be to identify the "easy wins" - where other public or private assets are not substantially at risk, the benefits well outweigh the costs and the overwhelming community asttitude supports repair works.
Final report
This project puts forward the proposal that stakeholders and government should concentrate on repair of the more developed coastal catchments around Australia where major investment and Australian Government leadership is required to re‐establish estuary productivity.
It seeks to deliver multiple benefits to the Australian community – to increase fisheries productivity, improve coastal water quality, enhance catchment hydrology, repair coastal biodiversity, finetune flood control, re‐establish carbon sequestration and reinforce foreshore buffering against extreme events.
The business case sets out the rationale and the priority opportunities for investment, to repair and restore, under a 'no regrets' policy, estuary and inshore wetland and floodplain areas. It seeks to maximise community benefits from these important parts of our landscape while minimising costs and impacts upon adjacent land users of the coastal zone.
It builds upon the Australian love of coastal landscapes and the resources they provide and the Australian community’s and political commitment to implement major natural resources initiatives such as the Natural Heritage Trust, Caring for our Country and the Biodiversity Fund. Like Reef Rescue and the National Action Plan for Salinity and Water Quality, the business case proposes a major focus, in this case on estuaries and their wetland ecosystems.
Most importantly, through ongoing fisheries productivity, the proposed once‐off five‐year Australian Government investment will return economic benefits year in and year out that will far outweigh the $350M costs of repairing these key estuary assets. Our estimates suggest a break‐even for investment is well less than five years and from then on benefits exceed costs forever.
Further repair and management investment will be required following the proposed once‐off five‐year agenda‐setting Australian Government investment. This business plan recognises this ongoing investment need. Similar to already successful schemes in USA and UK and building on schemes already underway in NSW and Victoria, this plan proposes various instruments and systems to ensure overall benefits can be incentivised into the future. This includes empowering industry groups, private landholders, Local Governments and communities to continue the repair of coastal assets and their management.

Seafood CRC: funding options for the Australian wild-catch prawn industry
Seafood CRC: maximising the quality of Australian wild-caught prawns (Quality Assurance)
Despite overwhelming support for industry investment to implement the national prawn market development strategy developed by Brand Council (CRC 2011/736), a major aligned industry concern was the inconsistent quality of, in particular wild caught prawns, and how this inconsistency may have the potential to negatively impact the market development activities. The Australian wild catch prawn industry is widely distributed and characterised by variation in geography, target species, operating/harvest systems, size of vessel and operator capabilities. Additionally, there can be high staff turnover, language and cultural differences and literacy issues. This leads to inconsistent product harvesting, brining, cooling, preserving, packaging and grading and/or inappropriate processing, which causes inconsistent product quality. Such quality issues can be exacerbated by poor handling at both retailer and consumer level.
While prawn quality standards have previously been created, there has been little integration, acceptance or uptake of these standards and associated training by indutry More often, standards have been created at fishery, company and vessel level, or are at the request of down chain partners. With considerable industry investment to both develop and implement the national Australian prawn strategy, there is now a greater incentive for the production of a consistent quality product to underpin the Australian prawn strategy messages/activities and ensure the best possible prawn experience for consumers.
Final report
The wild harvest Australian prawn industry and aligned down chain stakeholders have access to a suite of resources to ensure a consistent, high quality Australian prawn product.
• A consumer information pamphlets circulated to >400 retail outlets in 2014 and 2015 respectively.
• Retail poster circulated to >400 independent retail outlets.
• Online training resource for crew & skippers developed and piloted.
• An agreed set of parameters describing a “quality” Australian prawn.
• Best practice documentation/guides produced for fishers, wholesalers & distributors, retail and food service, and consumers.
• >15 industry and conference presentations
• Two industry magazine articles
Seafood CRC: controlling biofouling of pond aerators on marine prawn farms
Biofouling of aeration equipment is a significant farm management issue and production cost for Australian marine prawn farms. Defouling aeration equipment has a high labour demand and once fouled the energy efficiency of paddle-wheels and other aerating equipment can be markedly reduced, leading to elevated electricity costs and shorter equipment life. The estimated cost of biofouling is a minimum of $1,000 per hectare per crop when considering the additional labour, maintenance and electricity costs that it creates. This cost figure however does not include the impact of aerator fouling on prawn production levels which potentially could be far greater. The industry uses up to 10x aerators per hectare and they consume 70-80% of total farm energy use. It is estimated that at the peak of the production season around 6,000 2hp aerators are in use in ponds across the prawn industry alone.
Ensuring appropriate and timely aerator defouling is conducted is a significant farm issue. Manual defouling is one of the least desired tasks on the farms as it is dirty, laborious and workers are susceptible to multiple skin cuts that are prone to infection. Consequently it can be difficult to maintain staff to undertake this task for any length of time.
There is no data available on the impact of biofouling on the aeration efficiency, for example the oxygen transfer rate, and this information is critical to maximising benefit from mitigation strategies from both a practical and economic stand point.
The relevant industry body, the APFA through the R&D Committee, has assessed prevention of aerator biofouling as a priority issue and has recommended that the project commence as close as possible to the start of the current production season.
The proposed project falls within the Seafood CRC Theme – ‘Aquaculture Innovation’ as the objective is to improve production efficiency.
Final report
Biofouling of aeration equipment is a significant farm management issue and production cost for Australian marine prawn farms. Defouling aeration equipment has a high labour demand and once fouled, the energy efficiency of paddle-wheels and other aerating equipment can be markedly reduced, leading to elevated electricity costs and shorter equipment life. The estimated cost of biofouling is a minimum of $1,000 per hectare per crop when considering the additional labour, maintenance and electricity costs that it creates.
The project was designed to assist the Australian prawn farming industry improve aeration efficiency through providing farms with new information pertinent to cost-efficient management of their aerator fleet. The project focussed on the impact of biofouling on aeration and measures to control its accumulation, though broader aspects of aeration were also considered.
On-farm monitoring of aerators determined a huge variation in aerator electrical performance within and among farms. Around 60% of the electrical use variability among paddlewheels is due to biofouling accumulation. This also means that around 40% of differences among paddlewheels is attributable to mechanical factors such as degree of wear and tear.
The overarching output from the research conducted under this project is an improved understanding and quantification of the problem of biofouling in the use of aerators in marine prawn ponds. Farms are under pressure to become increasingly efficient production systems and the information arising from this project will substantially contribute to the farm knowledge base drawn on to optimise strategies that reduce aerator fleet management costs.
