The Australian salmon industry is free from the major infectious diseases affecting salmon industries in other countries. Amoebic Gill Disease is the main infectious disease affecting the salmon industry in Tasmania. While this disease occurs in other countries, it does not appear to be as severe as in Australia. The disease-related fish mortalities are greatly reduced by freshwater bathing, however the disease treatment results in greater production costs and reduces the Australian salmon industry’s ability to compete in international markets. While development of a vaccine to protect against the causative agent is a desirable solution for the industry, it must be appreciated that this is a challenging task and requires a long-term view. In the meantime, the industry needs more knowledge of AGD epidemiology and more tools to improve management of fish with AGD on the farms, which would improve AGD treatment and control and decrease the risk of large outbreaks of AGD. As a direct result this should lead to reduced production costs. Improved understanding of the epidemiology of the disease will also provide a valuable basis on which to develop strategies for vaccine application in the future.

The ultimate goal is to have an AGD surveillance system in place, to provide information about the host, agent and environment which is relevant to prevention and management of the disease. The results will improve our understanding of factors contributing to AGD outbreaks and will develop a best industry practice protocol aimed at the reduction of AGD effects on the salmon industry in Tasmania. Information from the surveillance system will facilitate better decisions on the timing of treatments as well as provide long term data for analysis to identify additional management strategies aimed at minimisation of disease risks and economic impacts. Specifically, farm-level surveillance data will eventually provide a basis for measuring spatial and temporal trends in AGD occurrence in both the host and potential reservoirs as well as environmental and production factors associated with changes in AGD occurrence. Analysis of retrospective data will permit the identification of improved management strategies as well as providing farm managers with a more reliable basis on which to make decisions on prevention and control. This project will provide ways of value adding to the data collected by the salmon industry in general. It will protect individual company interests with respect to privacy of commercial information.

To achieve the complementary outcomes of sustainability and economic benefits to the stakeholders in the SEF, a whole of chain approach to R&D is required (which is in accordance with government direction on R&D planning). Current practice focuses on the biology and fishery management which has precluded more innovative ways of adding value. Following a workshop held in November 1999 (Canberra) a recommendation was made that FRDC develop a subprogram to support the industry development component of R&D for the SEF. This application will develop the subprogram over the next year and produce a Strategic Plan that incorporates a whole of chain approach.

Management decisions should be based on good quality data. Any steps taken to improve an inadequate baseline will eventually improve data quality and the subsequent cost effectiveness of obtaining these data. Any part of the baseline where confusion can arise should be identified and improved as soon as possible. The fisheries coding system knees to be enhanced to improve its functionality to clarify names and assist users when obtaining or vetting fish data. It will also prove an important baseline for a variety of other industry uses. The resources are presently available to improve this baseline and these may not be available in the future. It also coincides with a period of activity whereby the names our seafood will be standardised and legislated. The project is timely and should be completed now.

In addition to the commercial fishing industry, fish names are frequently referred to by an extremely broad variety of groups including administrators, aquarists, editors, educators, lawyers, legislators, recreational fishermen, scientists, seafood consumers and writers. The need for a standard list of common names of Australian fishes was eloquently flagged by eminent Australian scientist, Gilbert Whitley, some thirty years ago (see attached excerpt from his paper, appendix 4). A national nomenclatural standard covering all Australian fishes is long overdue - no such standard presently exists for secondary commercial any bycatch species. CAAB has now been adopted as the industry wide coding system but would be considerably more useful if it contained standardised common name information and an image of each species.

The unavailability or inconsistency use of common names of fish has created a problem for all sectors of the seafood industry. It has also led to serious confusion when interpreting catch return sheets and fisheries data based on common names. Even the guidelines of this application form (ie Project title and identification) request the use of the approved marketing mane of each species. However, most secondary commercial and almost all bycatch species have not been allocated a single approved common name.

Whereas the process of establishing single names for the main commercial species has been contentious, it is likely to be much simpler for the remaining fishes. If approached properly, the task only needs to be done once. The final product should be definitive work on the common names of Australian fishes requiring minimal alteration in the future.

The recently published Australian Seafood Handbook has created many enquiries from governmental and commercial groups wanting to gain access to images held in the CSIRO fish image library. However, in it s present form, this image collection cannot be accessed cost effectively.. The bulk of the collection is in celluloid format and the digital component has bot been assigned to a search and retrieval oriented database. Hence, it is presently grossly under utilised. A logical step is to digitise the collection and make the images freely available on the CAAB website, simultaneously improving accessibility and making CAAB more user friendly.
