Summary
Abalone farming can be improved in Australia. The profit will be increased and the cost of production reduced:
· increased knowledge of the settlement process and development of a better settlement system resulting in low cost juvenile abalone is essential for both integrated abalone farms and for the supply of seed to growout farms;

· increased knowledge of the settlement process and development of a better settlement system resulting in low cost juvenile abalone is essential for both integrated abalone farms and for the supply of seed to growout farms;
· the development of a practical settlement protocol for abalone requires a greater understanding of microalgae requirements and their culture and reduces the cost for abalone at the growout stage;
· the project will be integrated into the abalone aquaculture sub-program and has extensive industry involvement in developing the practical aspects;
· the aquaculture industry in Victoria is developing into a major growth area and investment opportunity and production is intended to triple by the end of 2001;
· the success of the Australian abalone aquaculture industry is dependent on developing methods that reduce costs in labour and growout time;
· the project will deliver information that can result in technically advanced culture methods that will maintain the competitive edge over low labour cost countries. Objectives: 1. To test performance of different settlement inducers at both the laboratory and commercial scale. 2. To improve the rate and consistency of abalone larval settlement. 3. To compare different microalgal diets for their nutritional value in terms of digestibility and growth. 4. To quantify the suitability of different microalgae for their ease of use, both for maintaining mass cultures and ability to recolonise settlement surfaces. 5. To increase growth and survival for the first two months of post-larval life at a commercial scale. Read moreRead less

This can create a number of challenges, foremost of which is incompatible management arrangements applying to the same fish stock across jurisdictions. Other issues include the lack of awareness, engagement and communication between fisheries managers working on common fisheries problems across jurisdictions and reductions in government funding for fisheries management and research.
There is a recognised need to increase cross-institutional engagement so line managers (as in those staff engaged in the development and implementation of fisheries management and policy) are made more cognisant of the work being undertaken across jurisdictions, thereby increasing their knowledge, skills and understanding of fisheries issues and solutions, with the aim of achieving management efficiencies. Due to budgetary cuts and increased workloads, Australian fisheries managers have very little time or opportunity to communicate and network with their associates within other institutions. The establishment of a professional association of Australian fisheries managers would facilitate collaboration and engagement by providing a forum for discussion/debate as well as acting as a repository for information and coordinator for future workshops and meetings on key focus areas. Qualified and experienced fisheries managers, despite their pivotal role in sustainable fisheries, are largely unrecognised as inter-disciplinary professionals in their own right. This is in contrast to fisheries biologists and economists. The formation of the association could lead to increased recognition of fisheries management as a profession. There would also be a value to industry through synergizing management approaches across jurisdictions, increasing efficiency and thereby reducing possible costs of management.
Objectives: 1. Establishment of Professional Association of Australian Fisheries Managers 2. Improved accessibility and transparency of jurisdictional fisheries management information (technical papers, policy and legislation) through hosting of a central website 3. Increased recognition of the profession of fisheries management within Australia and the current work undertaken by managers to ensure fisheries remain sustainable 4. Exposure of fisheries managers to innovations and developments in fisheries ecological, economic, social and political fields in Australia and overseas 5. Improved consistency and transparency in management approaches between jurisdictions through greater information-sharing and liaison 6. Establishment of linkages between fisheries managers for future interactions and collaborative engagement 7. Improved public confidence in Australian fisheries management through greater stakeholder outreach and communication 8. Ensuring the Association has appropriate support (financial and logistical) to operate beyond the completion of the two year project Read moreRead less
A Multi-setting Intervention To Reduce Sedentary Behaviour, Promote Physical Activity And Improve Childrens Health
Funder
National Health and Medical Research Council
Funding Amount
$860,343.00
Summary
Sedentary behaviours and physical inactivity play a major role in the rising prevalence of obesity among children in Australia. This intervention study will take place in the school and family settings which play a critical role in shaping children's health behaviours. The objective is to determine whether a 2-year behavioural intervention reduces sedentary behaviour and promotes physical activity and results in improved health among 8-9 year old children.
Honesty and efficiency in the provision of expert services: doctors and other experts as participants in economic experiments. Experts serve us when we see the doctor, the financial planner or the car mechanic. In all these case the expert can take advantage of his superior knowledge and sell us something we do not need. This research will inform policy makers about the underlying motives of real world experts and allow them to design better institutions.
A sponsor’s page including logos will be included at the start and end of each session (4 times) and will include acknowledgement at the start and conclusion of the summit. Major sponsors will also be acknowledged in social media posts about the summit. A media release prior to the summit will include acknowledgment of major sponsors.

Summary
After southern bluefin tuna, King George whiting is the most important fish species in South Australia. This species attracts a high market price on local and interstate markets and has biological attributes which suggest that is has good potential as a candidate for aquaculture.

This species attracts a high market price on local and interstate markets and has biological attributes which suggest that is has good potential as a candidate for aquaculture. To allow commercialisation of this species, there is an immediate need to commence research to control egg production and conduct larval rearing trials to expose and solve culture problems so that a valid assessment of this species can be provided to aquaculturalists and investors.
FRDC funded research on the reproductive biology of wild King George whiting has identified a need to determine the spawning frequency of individual fish to get accurate estimates of fecundity.
There is a need to recognise that aquaculture is the only way to increase production of small volume coastal fisheries, such as that for King George whiting, without increasing fishing pressure on natural populations.
There is a need to develop aquaculture of coastal marine finfish species as an option which has potential to allow commercial fishers to diversify and reallocate effort to reduce pressure on wild stocks. Objectives: 1. Establish two breeding stocks of King George whiting and control egg production from one stock during the natural spawning season and from the other stock six months out-of-season. 2. Identify spawning frequency and periodicity to provide an accurate estimate of fecundity for fishery models. 3. Complete intensive larval rearing investigations to define environmental tolerances of larvae and to expose and solve problems during the larval culture period. 4. Document the behaviour of larvae in the water column at different stages of development. 5. Assess the potential of larval culture of King George whiting for commercial aquaculture. Read moreRead less
