Need

The overriding needs for this project are to maintain a sustainable fishery for P. monodon to ensure broodstock supply to the Australian prawn farming industry.

This project requests an early start in order to sample the two recruitments into the main fishery, and to address the lack of broodstock, to supply the doubling of the current size of the P. monodon farming industry in the following 1 to 2 years.

1) Little published information is available on wild broodstock biology and ecology, presumably because P. monodon is really an incidental catch. Nevertheless, information on the species has been collected in logbook programs (eg. QDPI, Bill Izard and Jim Brownings tagging of adult P. monodon in the Cairns/Innisfail regions), and in many studies directed at other penaeids. Information on the species is thinly distributed over a large number of datasets, uncollated and unanalysed. This study will undertake the collation of information over a 6 month period at the beginning of this project to assisst in refining later stages of this project.

2) Although considerable effort and resources have been allocated to the full domestication of P.monodon, both nationally and internationally, the commercial production of closed broodstock is as yet not viable. The P. monodon prawn farming industry is currently dependent on wild caught broodstock and will be for the foreseeable future. Pressures are building for the known wild stocks to supply an expanding local and international aquaculture market that is expected to double or triple in the following one to two years, yet little is known of the size and sustainability of currently sourced Queensland stocks of this species. There is a clear and present need to establish the size of the resource to maintain the existing industry and further establish a regular and sustainable supply of broodstock to ensure national expansion and viability of P. monodon prawn farming.

3). There is a need for alternative capture methods and associated stress testing to be assessed. This is required by commercial broodstock collectors and the Northern Territory fishery to capture the highest quality broodstock, source broodstock from different habitats, manage specific fisheries and to lessen environmental impacts of the fishery.

4). There is a need for an economic assessment of potential gains to the industry from optimising the quantity, quality and timing of the supply of P. monodon broodstock.

Attachment 1 provides a dissection of the research problem.

Objectives

1. Collate fisheries information currently available on P. monodon across northern Australia from grey literature, fisheries databases, research projects and from indigenous communities.
2. Define the distribution of adult P. monodon stocks and habitats.
3. Define the distribution of juvenile P. monodon stocks and habitats.
4. Determine seasonal patterns in P. monodon population dynamics (abundance, population structure).
5. Identify P. monodon biology (recruitment, movement, growth and reproduction) in Queensland.
6. Examine alternative capture techniques and the associated stress testing of caught broodstock, in particular for inshore and shallow water habitats which may contain useable quantities of currently unexploited broodstock.
7. Conduct economic cost/benefit analyses of various fishing patterns, capture techniques and handling protocols.

Seafood CRC: optimisation of viral clearance from broodstock prawns using targeted RNA interference

Economic losses due to diseases mostly caused by viruses remain a major obstacle to realizing the production potential of prawn aquaculture industries in many parts of the world. Broodstock used in prawn hatcheries in Australia are generally managed quite intensively and numbers used are generally...

Summary

Prawn farming is the most valuable aquaculture sector in Queensland and is a priority development industry for the State Government. Marine prawns have provided the major growth in this industry with a value of $37 million in 2000/01, or over 66% of the value of Queensland aquaculture. Nevertheless several issues need to be addressed to ensure the industry continues to grow and is economically and environmentally sustainable. 

The supply and performance of broodstock is seen as the weakest link in the production cycle, both overseas and nationally, and is viewed as a major research priority by the Australian Prawn Farmers Association (APFA). Presently the marine prawn sector is dominated by Penaeus monodon production, the broodstock of which are obtained from the wild fishery in a few near-shore coastal areas in northern Queensland. Recent screening of wild-sourced broodstock for viruses has revealed that nearly all of them, from the traditional areas of supply, are carriers of potentially pathogenic forms   of   viruses.  In response, the industry has developed a strategic goal of becoming a true farming sector by shifting its reliance on wild broodstock toward totally closed life cycle production. Research providers and industry are now committed to developing domesticated broodstock that will eventually be used in selective breeding programs to produce specific strains or breeds.

This project placed special emphasis on strategic issues, to develop solutions to current and future challenges for prawn hatcheries, and applied issues, with effort directed towards clear and identifiable objectives in improving broodstock reproductive performance. Strategic issues included developing specific research tools to investigate some of the basic mechanisms that underpin reproductive capability and its physiological control in P. monodon (Objectives 1 and 2). This information is essential if informed knowledge-based improvements in broodstock management are to develop in a vigorous manner. Applied issues included the objective of comparing reproductive performance of captive-reared broodstock that had been grown to sexual maturity in either tanks or ponds (Objective 3). The final objective was directed to examining supplementation of specific compounds in broodstock maturation diets and their impacts on subsequent reproductive performance
(Objective 4).

Seafood CRC: increasing seedstock production of domesticated giant tiger prawns (Penaeus monodon) through improved male fertility

Given the rationale that pond systems are likely the most cost-effective system for large-scale production of Giant Tiger Prawn (Penaeus monodon) broodstock, this project aimed to determine whether pond-rearing poses a significant risk for broodstock production. The gross reproductive development of...

Need

Australia's prawn farmers have developed a five year R&D plan through rigorous consultation throughout the industry and with other stakeholders, such as R&D providers and funding agencies.

As a result Australian prawn farmers have identified their primary objective from investment in R&D is achieveing growth in an economic and environmentally sustainable manner.

They aim to do this by investing to increase the industries average production from 4t/ha to 8t/ha, increasing the farm gate value of farmed prawns from $14/kg to $16.50/kg whilst continuosly improving environmental management.

The R&D required to underpin achievement of these objectives has been broken down into three programs:
1. Improving domesticated broodstock
2. Improving prawn farm productivity
3. Improving farmed prawn market value

As such industry support for project development is based on both proposed new projects and existing projects contributing to achieveing these objectives.

Within the Seafood CRC industry involvement in project planning and review is considered a must, as is maintenance of the relevance of the R&D strategy. The Executive Officer position will be responsible for achieving this under the direction of the APFA Executive Committee.

Objectives

1. To ensure that the Australian prawn farmers are driving the direction and utilising the outcomes of their R&D investment to achieve targetted growth
