Summary
The present project relates principally to Programs 1 (Environment) & 2 (Industry) of the FRDC’s Strategic priority areas. Specifically the project will increase the gross value of production, profit margins, productivity and opportunity (Theme 7) for Huon, through providing the company with a means to expand operations into offshore and more exposed fish farming areas. The successful use of the well-boat also extends to Theme 1 through providing a means to prevent and manage disease incursion ....The present project relates principally to Programs 1 (Environment) & 2 (Industry) of the FRDC’s Strategic priority areas. Specifically the project will increase the gross value of production, profit margins, productivity and opportunity (Theme 7) for Huon, through providing the company with a means to expand operations into offshore and more exposed fish farming areas. The successful use of the well-boat also extends to Theme 1 through providing a means to prevent and manage disease incursions through providing a biosecure vessel for transferring fish between marine sites.
On a broad operational level the project is needed in order to: 1) Allow the company to expand offshore 2) Ensure the cost effective use of the well-boat at inshore and offshore sites 3) Provide low risk SOP’s for bathing on board the well-boat
To make the use of the well-boat cost effective Huon has to both reduce the time for bathing so that more baths can be undertaken during appropriate weather conditions, and the well boat has to be able to reuse freshwater or find a method for bathing in seawater that will greatly reduce the need to return to shore-based freshwater fill stations to re-load with freshwater as all fill stations are at least 50kms from the exposed water sites.
Objectives: 1. Design and test a water quality treatment system that allows multiple reuse of freshwater in well-boat bathing operations. 2. Adapt previous experience and experimentation of the use of Hydrogen peroxide as a therapeutant in both fresh and seawater bathing into Huon’s well-boat operations, including devising mechanisms and systems for freshwater reuse during treatment. 3. Provide detailed SOP’s for the previous objectives. Read moreRead less

Summary
Wild carp (Cyprinus carpio) are an invasive species found throughout Australian freshwater systems. The species is well established throughout the Murray-Darling basin (MDB) and makes up to 90% of the fish biomass in some areas. There are concerns that carp are damaging the ecology of MDB waterways and competing with native species for food.
The Australian Federal government has developed the National Carp Control Plan which will assess the feasibility and potentially manage the release of Cyp ....Wild carp (Cyprinus carpio) are an invasive species found throughout Australian freshwater systems. The species is well established throughout the Murray-Darling basin (MDB) and makes up to 90% of the fish biomass in some areas. There are concerns that carp are damaging the ecology of MDB waterways and competing with native species for food.
The Australian Federal government has developed the National Carp Control Plan which will assess the feasibility and potentially manage the release of Cyprinid herpesvirus 3 (CyHV-3) as a biocontrol agent for the invasive carp. The virus is expected to reduce the carp population by between 70–95% within the first few years. Initial release at breeding sites is expected to wipe out primarily juvenile carp at first, followed by mature fish. It is anticipated bird-life will consume a large portion of the immature carp however deceased mature carp present an environmental challenge as their decomposition may impact upon water quality. The large mass of deceased carp will require a large scale clean-up and present a unique opportunity to be utilised for fish products.
Currently carp are harvested for use in fertiliser; however as estimates of the deceased biomass are in the hundreds of thousands of tonnes, other avenues for utilisation warrant further investigation. Compositional analysis, suitability of CyHV-3 infected fish for processing, pilot scale production trials and subsequent market appraisal is required to realise new product streams. Development of new products utilising the infected deceased carp will assist in the clean-up, reduce disposal costs and potentially generate income for the local economy.
Objectives: 1. To identify, pilot and undertake subsequent cost benefit analysis (CBA) for developing new processes/products from deceased feral carp (as part of National Carp Control Plan). Read moreRead less
Objectives: 1. Consider the potential, economics, techniques and engineering aspects of aquaculture of freshwater fish & crustaceans. 2. Prospects for aquaculture industry. Inform participants of latest techniques and developments, identify research requirements

It is indeed significant that the comments provided in “Australia : State of the Environment” on each of the ten key threats to sustainability confirm that indicators of all ten show continuing deterioration.
While most of this broad spectrum of issues has been the subject of at least some research our knowledge of the interrelationships betwen fisheries and fresh water ecosystems remains seriously inadequate. Urgent requirements include:
· a current review of the factors which influence productivity of Australia’s inland fisheries, · correlation of cause and effect for the major threats identified, · correlation of cause with the relevant management or regulatory authority, · an assessment of data and knowledge (research) needed to facilitate management action, · an assessment of areas where research is most likely to lead to significant management action, . an evaluation of what strategies have worked, or are working, in one or more State or Territory and assessment of the likelihood of success from nationalising, or at least broadening or transposing, this strategy, . an assessment of potential cooperative approaches to commissioning and funding priority research Objectives: 1. To identify the key issues facing the sustainability of Australia's freshwater fisheries resources and suggest strategies for addressing those of highest priority. Component objectives include: 2. To identify the major threats to sustainability of freshwater fisheries resources in each State and Territory. 3. To identify the probable primary causes for the most significant threats in each State and Territory. 4. To assess which threats could be approached by a national or State to State cooperative strategy for research. 5. To propose a national strategy for coordinating and funding new research relevant to ensuring the sustainability of Australia's freshwater fisheries resources Read moreRead less
