Seafood CRC: review of traceability and freshness indicator technologies
As an input to Business Plan development by the Australian Seafood CRC for the Product Quality and Integrity Research program, conduct an examination of traceability and freshness indicator technologies that are relevant to the Australian Seafood Industry
Final report
Tactical Research Fund: A review of the ecological impacts of selected antibiotics and antifoulants currently used in the Tasmanian salmonid farming industry and development of a research programme to evaluate the environmental impact of selected treatments.
The Tasmanian salmonid industry has recently been faced with several significant production issues necessitating increased use of antibiotics and antifoulants. The effects of these chemicals on the local ecology and ecosystem function are currently poorly understood and without evidence to the contrary, it is difficult for the industry to refute the perception that such chemicals have a detrimental effect on the environment.
There is a large body of literature regarding the effects of antibiotics, however the information pertaining to aquaculture is limited. Improvements in husbandry and vaccine development have now all but eliminated the use of antibiotics in aquaculture overseas, consequently there have been few recent aquaculture specific studies, with even fewer studies on ecosystem effects, the available information largely focussing on environmental persistence and antibiotic resistance. However, there is quite a lot of information in the terrestrial livestock and medical areas on the comparative effects of various antibiotics as well as quite a substantial ecotoxicological literature. In contrast there is a substantial local literature on the environmental impacts of antifoulants and heavy metals. There is a need for a targeted review to establish environmental risk factors associated with current antibiotic and antifoulant usage and to develop an appropriate strategy to research and monitor ongoing impacts.
Some data on sediment residue levels for both antibiotics and antifoulants has been collected by the salmon industry in compliance with drug/chemical licensing permit conditions authorities and by the state government in response to concerns regarding antibiotic usage. So far this data has not been collated and has only been subjected to preliminary analysis; a comprehensive evaluation of this data would markedly improve our understanding of current impacts and help to determine what additional information may be required.

SESSF Industry Development Subprogram: alternative fuels for fishing vessels
With most of Australia's fish stocks at fully fished or overfished status, there is reduced opportunity for increasing economic returns from larger catches or unexploited resources. As a result, the fishing industry is looking for opportunities to increase its profit margins by reducing the cost of fishing. Generally, fuel is the one single highest operating cost to fishing vessels, accounting for up to 50% of the operating costs of a fishing vessel in Australia.
The Australian (and New Zealand) Fishing Industry requires assistance in becoming a more efficient user of energy. Some forms of fishing, such as trawling, expend more fuel per kg of fish landed compared to passive methods such as longlining and trap fishing. In all cases however, rising fuel prices impinge on the profitability of the operations, and ultimately put their viability in jeopardy; this has reach a critical situation for many operators in Australia.
The R&D plans and strategies of all advisory bodies to the FRDC contain high priority goals to achieve FRDC’s Industry Development goal (planned outcome):, The commercial sector of the Australian fishing industry is profitable, internationally competitive and socially resilient. This investigation into alternative fuels for the fishing industry, some of which also achieve lower greenhouse gas emissions, has the intention of improving the economic viability of fishing enterprises and shifting the industry towards a more secure position with respect to future fuel needs.

Rebuilding Ecosystem Resilience: assessment of management options to minimise formation of ‘barrens’ habitat by the long-spined sea urchin (Centrostephanus rodgersii) in Tasmania
Investigating options to improve bycatch reduction in tropical prawn trawl fisheries - a workshop for fishers
Australian Society for Fish Biology Conference and Workshop 2006 - cutting edge technologies in fish and fisheries science
The ASFB Annual Conference and workshop provides an opportunity for scientists, managers, industry and communities from the various jurisdictions around Australia, New Zealand and the South Pacific, to come together and discuss the most recent developments in fish and fisheries science. The workshop specifically enables a topic of national significance to be discussed in an open forum in the presence of acknowledged international experts.
Recently we have witnessed a rapid expansion of methodologies and applications in our discipline that enable us to investigate the environment in new ways. There is thus an opportunity through the ASFB workshop to showcase the application of new techniques and technologies across a range of disciplines. Examples include smart tags, acoustic tracking, hydro-acoustics, remote sensing, habitat classification, underwater visual systems, electronic data capture, genetic and microchemistry applications.
Conferences and workshops such as this are a key component of the skill development of people in the sector, particularly offering students and young scientists the opportunity to obtain new ideas in a relaxed and informal setting.
Final report
The FRDC provided funding to support the organisation and hosting of the 2006 Australian Society for Fish Biology (ASFB) conference and workshop on cutting-edge technologies in fish and fisheries science. This funding was matched by sponsorship from a range of government, university and industry sources. Internationally recognised plenary presenters included Ron O’Dor of the Census of Marine Life, and Pamela Mace of the Ministry of Fisheries (NZ). The event was hosted in Hobart in August/September 2006 as a 2-day workshop and 2-day conference.
Keynote and panellist presentations involving invited speakers addressed each of the themes, many of these presenters being generally recognised internationally for their expertise in their particular research field.
The conference program involved around 150 oral presentations along with over 30 poster presentations. Papers were grouped into a range of themes, including fisheries assessment and management, recreational fisheries, movement and stock structure, early life history, biology and physiology, underwater technology, habitats and mapping.
Overall the event was an outstanding success, attracting over 320 delegates, representing the largest attendance for an ASFB national conference to date. Significantly, universities were well represented, with about 90 students attending the event. Approximately 25 international delegates from New Zealand, north America, Europe and Asia attended.
An evaluation survey of workshop participants revealed that benefits that will flow into the broader research agenda through adoption of latest techniques/technologies and through increased collaborations and partnership.
Workshop proceedings were published within 12 months of the event and have been distributed to workshop participants, research agencies, funding bodies and libraries. Downloadable pdf versions of the proceedings are also available from the ASFB website.
