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

SCRC: PhD: Profiling Host-parasite Dynamics Of AGD Using Molecular DNA Methods – Application To Vaccine Development, Selective Breeding And Offshore Aquaculture

Summary
Amoebic gill disease (AGD) research remains a high priority for the Tasmanian salmon industry. Within this framework there is a need to develop, both for research and practical reasons, non-destructive quantitative measures of AGD severity. This PhD project will develop a state of the art quantitative real time PCR (qRT-PCR) method for AGD-causing Neoparamoeba perurans. If successful this will be the first such DNA test of its type in the world for this disease. The assay will then be utilised ....Amoebic gill disease (AGD) research remains a high priority for the Tasmanian salmon industry. Within this framework there is a need to develop, both for research and practical reasons, non-destructive quantitative measures of AGD severity. This PhD project will develop a state of the art quantitative real time PCR (qRT-PCR) method for AGD-causing Neoparamoeba perurans. If successful this will be the first such DNA test of its type in the world for this disease. The assay will then be utilised to answer practical questions such as profiling host-parasite dynamics in vaccinated and non-vaccinated salmon prior to, during and after commercial freshwater bathing treatment, providing a rigorous measure of vaccine efficacy, and much-needed insights into the parasite loading exhibited by the different experimental salmon groups. The N. perurans DNA test will then be extended to selectively-bred salmon, correlating pathogen load with breeding values for resistance in F2 stock. This could provide a more reliable way of quantifying infection than current gill scoring methods, and will be the first time such a tool is applied to gain more precise information from a commercial salmon selective breeding program. Finally, the project will then apply the qRT-PCR test and other N. perurans molecular markers to the wider environment to address questions of population genetics, environmental reservoirs (providing much-needed information on the parasite life cycle, a prelude to in vitro culture which would benefit vaccine development), and parasite dynamics in heavily-farmed and virgin marine environments to address fundamental questions as the Tasmanian salmon industry contemplates a move towards off-shore aquaculture. This project is a high priority for the Tasmanian salmon industry and was adopted into the CRC at its inception. This PhD project has the support of the industry. The project also has strong alignment with the industry run selective breeding program.Read moreRead less
