Aquatic animal health training scheme - Updating and improving existing practical skills and knowledge to support the effective delivery of vocational aquatic animal health
There is a lack of practical skills for on farm fish health investigation and disease management. The National Aquatic Animal Health Technical Working Group (NAAH-TWG) April 2008 workshop highlighted - 'There is ongoing concern that there are too few suitably trained and accredited aquatic animal health professionals to service Australia’s fisheries and aquaculture industries and to ensure succession to a new generation of aquatic animal health professionals.' More recently Dr John Humphrey's presentation at the 2010 Australasian Aquaculture Conference 'Disease investigation in finfish - demystifying the diagnostic process' discussed the need at an industry level for an improvement in investigating fish health skills across the aquaculture industry.
Every state of Australia has an aquaculture industry which requires effective health investigation and disease management. Across Australia aquatic animal health training is being delivered to industry and future stakeholders by vocational trainers using units from the National Seafood Industry Package. Aquatic animal health training is also occurring on the farm informally by other industry professionals.
There is a need to bring together those delivering training, to allow them to update and improve their knowledge and practical skills to enable better delivery and ultimately better outcomes for skill development in farm fish health investigation and disease management to support Australia’s fishing and aquaculture industry.
Final report
People Development Program: Aquatic Animal Health Training Scheme: Introductory training workshop in surveillance for aquatic animal diseases
Disease surveillance is an essential component of any aquaculture industry. Surveillance is required for early detection of new or introduced diseases, to demonstrate freedom from certain pathogens to support trade or to monitor and respond to changes in disease prevalence in a population.
However, surveillance is a specialised science and design of surveillance programs depends on the specific purpose of the surveillance and what it is expected to achieve. Inappropriate surveillance design risks either wasted resources (doing more than is necessary) or failure to achieve objectives due to poor design, inappropriate methods or inadequate sample size.
Effective surveillance is also a critical element to support trade, particularly where disease status can be used as a non-tariff barrier to trade. Understanding the principles of surveillance program design and implementation will ensure that government agencies are equipped with high quality information to support claims to freedom from diseases of trade importance, where this is appropriate or necessary.
Aquatic animal health advisors have a broad responsibility, including implementation of surveillance programs. This course will address that need by providing guidance on the design and implementation of surveillance programs for a variety of purposes and at both farm and industry level in aquatic animal industries. This will enable stakeholders and investors to have confidence that surveillance is meeting the desired objectives and supporting the industry in producing a safe and sustainable and disease free product for domestic and international markets.

Aquatic Animal Health Subprogram: detection and management of yellowtail kingfish (Seriola lalandi) health issues
A Yellowtail Kingfish Aquaculture Industry R&D Committee has been established which includes representatives of industry, State and Commonwealth Governments and the scientific community. The Committee has recognised disease management and disease risk identification as high priorities in a 2003-2008 draft Strategic R&D Plan, presently under development. These are in line with the research and development priorities for aquaculture identified by the South Australian Fisheries Research Advisory Board. Targeted priorities that this project will address within industrial development include, fish health, farm husbandry, and public perception. With regard to natural resource sustainability, this project will help in environmental protection and will contribute to the development of best environmental practices.
Prevention is the best and most cost-effective strategy for managing disease. Furthermore, Australia’s lack of vaccine and drug availability to aquaculture makes other forms of prevention the only viable option for Australia. There are four requirements that must be addressed in order to have an effective preventive program. First, one must be able to anticipate the problems one may face. A preliminary assessment of the risks of disease development and amplification is an important first step. Second, the knowledge of accurate identification of clinical symptoms and pathology by trained farm staff allows a mechanism for early detection and categorization of potential fish health problems. Third, the mechanism is an ongoing system of vigilant observation and recording in the form of action-based detection of emerging changes. Finally, one must identify actions that should be taken in response to laboratory and disease-related findings.
Before recommending the best disease management practices, one must first inventory the industry needs and identify the gaps in knowledge and infrastructure that limit capacity to achieve disease control objectives.
Final report
Since 1999, the kingfish (YTK, Seriola lalandi) aquaculture industry has been a significant investor in South Australia’s regional economy. Currently, the annual YTK production is 2,000 tonnes and is anticipated to approach 7,000 tonnes by 2008 with a retail value of $55 million. The industry provides both direct and indirect jobs for up to 1050 workers in regional communities. Although still in its infancy, this aquaculture industry has been a major success story in the expansion of the Australian seafood and food-animal industries, and there is tremendous potential for the continued development of a sustainable and economically successful Australian finfish aquaculture industry. However, international experience has shown that one of the most pervasive and persistent limits to the growth and viability of a new finfish sector is disease. To date, the YTK industry of South Australia has enjoyed limited losses due to disease, nevertheless, anticipating, preventing and dealing with future diseases is a priority of industry, government and researchers. Consequently, disease identification, risk analysis and health management were deemed key approaches for this FRDC project.
The literature review, risk analysis, guidelines to management and photographic pathology book have stimulated a much greater awareness of potential and future needs, opportunities and safeguards for the YTK aquaculture industry of South Australia for PIRSA, researchers and diagnostic service personnel. This project may form the basis for (or at least stimulate) further applied R&D and the development of tools to control diseases. The development of best management practices, integrated health management procedures, disease surveillance programs or amendments to current fish health regulations may also arise, provided industry and government bodies work as partners with mutual intentions.

People development program: scholarship program for enhancing the skills of aquatic animal health professionals in Australia
Australia requires an effective system of aquatic animal health management to support Australia’s aquatic animal industries (e.g. aquaculture and fisheries, including the aquarium sector) and to protect Australia’s aquatic ecosystems and fauna. To be effective, the system needs well-trained and competent aquatic animal health professionals (including industry) with skill sets across a range of specialist disciplines and an understanding of their disciplines in an industry context. Professionals in this context refers to people working in the field of aquatic animal health including industry.
