Hatchery feeds workshop
There is already considerable Australian research commitment to the production of hatchery feeds and to the development of new feeds. Many research insitutions have a proven track record in development of production technology, but with the expansion of aquaculture in Australia there is a clearly defined need to improve coordination between the research organisations in the area of fish larvae feeds, and to identify opportunities and priorities for future research.
In October 99 McKinnon acted on advice from QFIRAC and FRDC, and canvassed support for a live feeds workshop. All respondents indicated support, but indicated that such a workshop should encompass all aspects of hatchery feeds research. We propose that the workshop will focus on hatchery feeds for finfish, and will aim to summarise the current status of research within Australia, identify gaps in research effort, and prioritise research needed.
Final report
With the expansion of aquaculture in Australia there is a need to improve coordination between and within both the R&D and industry sectors with regard to the study of hatchery feeds, and to identify opportunities and priorities for future research. The recent world shortage of the brine shrimp Artemia has precipitated a crisis situation in aquaculture hatcheries. Accordingly, in late 1999 FRDC commissioned a Hatchery Feeds R&D Plan, which was developed at a workshop held in Cairns, Queensland, on 9–10 March 2000.
The aquaculture community was widely polled to establish industry priorities for future research. A questionnaire was sent to all stakeholders, together with an invitation to attend the workshop, which was held in Cairns on 9-10 March 2000. Researchers were invited to present the results of work in progress, and industry needs were canvassed in open forums.
For convenience, the subject was divided into 5 main areas of research: microalgae, rotifers, brine shrimp, copepods and formulated diets. Status reviews were commissioned in each of these areas, and priorities in each defined in the workshop. In all areas, the need to benchmark best practice and to more efficiently transfer research results to industry were highlighted.

New targets for aquaculture - stage 1
Seventh international symposium on genetics in aquaculture
As the Australian Aquaculture Industry makes more use of genetic techniques, and works more with fully domesticated stock, there is a need to be fully informed of advances in this area. To remain competitive, and to maximise the effectiveness of limited research funds, industry and government will require to identify and access technologies developed overseas as rapidly as possible.
Advances in genetics are occuring at considerable speed and there is a need to establish and maintain interactions with research groups worldwide. The effectiveness with which this can be done is enhanced not only by demonstrating the research skills developed in Australia, but by exposure of International scientists to Australia, it aquaculture industries and research groups.
Holding the 7th International Symposium on Genetics in Aquaculture in Australia will provide an excellent opportunity to provide this exposure, to establish or strengthen networks, and, by maintaining the tradition of the "Genetics in Aquaculture" Symposia, establishing our position in the International scene in this area of research and technology development.
The importance of this area of research and technology development was demonstrated by the demand for, and the conduct of, a national meeting on Genetics in Aquaculture in Perth in Sept 1998 supported by FRDC. At that meeting, the development of international interactions were identified as an important requirement for Australia.
Final report
The successful staging of the Seventh International Symposium on Genetics in Aquaculture, the premier international conference for genetic experts specializing in Aquaculture, for the first time in the southern hemisphere, has led to greater exposure of the Australian Aquaculture Industries to that group. It also facilitated the development of new contacts between Australian researchers and industry members with those overseas and provided a venue for exchange of the latest information in aquaculture genetics between Australian researchers and the international community. Considerable media interest during the conference raised the profile of genetic applications in Aquaculture. Positive feedback was received from research and industry groups as to the value of the conference.

Impact of prawn farm effluent on coastal waterways
The need for the research described in this proposal was initially identified in two major reports instigated by the FRDC.
· The Macarthur Report (1995), identified that "The industry and the key researchers do not yet fully know the effect of nutrient and suspended solids on specific coastal ecosystems and hence are unable to estimate sustainable loads."
· The Queensland Fisheries Research and Development Strategy (1995-2005), recommended a strategy to "Assess the relative impacts of different Aquaculture methods on the environment." (Strategies 1.2.4, p. 5), "Provide a scientific basis for the objective evaluation of sustainable fisheries and Aquaculture management options.", and to "Develop sustainability indicators for fisheries." (Strategies 2.1 and 2.3, p. 6).
The proposed research will provide the missing information, identified in these two reports as being "….the effect of nutrient and suspended solids on specific coastal ecosystems…", and will "Assess the relative impacts of different Aquaculture methods on the environment." This proposal is a logical and necessary step forwards for the research co-ordinated through the CRC for Aquaculture which, until now, has focused on optimising farm operations and minimising effluent loads.
The urgent need for a co-ordinated research program to investigate the environmental impacts of prawn farm effluent was identified in a series of workshops held in Cairns, Townsville and Brisbane from July to September 1996 (see Discussion Paper, Appendix 1). These workshops affirmed that the current research priorities are to determine the composition of prawn farm effluent, to determine the impact of the effluent in coastal waterways and to investigate methods to minimise levels of nutrients and sediment in effluent The research outlined in this proposal will begin the work necessary to determine the impact of prawn farm effluent in coastal waterways.
This research will deliver information required to estimate sustainable loads of nutrients and suspended sediments in coastal ecosystems, provide a scientific basis for the evaluation of aquaculture management options, and assist in the development of sustainability indicators for aquaculture. It will therefore be an essential component of a recent initiative of the QDOE to prepare a Regional Plan for coastal areas between Cooktown and Cardwell. This Regional Plan will contribute to the sustainability of, not just the prawn farming industry, but also the highly valuable commercial and recreational fisheries resources within this area, currently valued at above $200 million annually.
