Recently Completed Final Reports
The goal of FRDC is to provide free access to the final reports for all projects and ensure that information on current projects is easily found and is also accessible. To do this a new searchable database has been developed. FRDC are in the final stages of testing the database and it will be launched in early July 2010.
Should you require any final reports prior to the database being launched please contact the FRDC Communications Team on 02 6285 0414 or email Julie.Haldane@FRDC.com.au This list provides a quick snapshot of what has been completed in the past three months. For all older projects please visit the Completed Project Archives page.
Mitigating Seal Interactions in the SRLF and the Gillnet Sector SESSF in South Australia - 2007/041
Bycatch of Australian sea lions (ASL) in rock lobster and shark gillnet fisheries has been identified as a key threat to the species, which is listed as threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
Down load the final report
Evaluating the Performance of Australian Marine Capture FisheriesThe report looks at the current fisheries management systems around Australia and identifies gaps in our current knowledge. It then highlights the benefits that could be gained from changes to the current approaches. The report is based on an analysis of confidential interviews with more than 70 national and international experts.

A review of the ecological impacts of selected antibiotics and antifoulants currently used in the Tasmanian salmonid farming industry – 2007/246A review of the ecological impacts of selected antibiotics and antifoulants currently used in the Tasmanian salmonid farming industry – 2007/246 More information: Dr Catriona Macleod - 03 62277237
Aquaculture EMS – 2004/096The key objective of this project was to develop and produce an environmental management system (EMS) template document as a tool for the salmonid, oyster and abalone sectors of the Tasmanian aquaculture industry. For the oyster and abalone sectors, most of the industry’s operational practices were found to pose a low risk to the marine environment outside the lease area. The one environmental high-risk area of concern identified for the oyster industry was the potential translocation of invasive marine species between regions. The risk assessment also found that there may be some impacts on sensitive habitats, such as salt marsh, at a regional level. Most of the moderate, high and extreme risks to all industry sectors were external environmental factors. There was a low risk of the industry having a negative social impact at a state, regional and local level. The potential negative impact on industry sustainability by increasing regulation across all tiers of government was considered to be moderate.
Commercial marine floating tank system – 2008/038The outcomes of this project are improvements to the semi-intensive floating tank system (SIFTS ) which make this technology close to being market-ready for protected marine environments. An underwater mortality detection and removal device was developed, along with an efficient method of transferring and processing the solid waste that the SIFTS captures. As well as being relevant to the SIFTS deployment into protected ocean environments, the improvements are also of direct relevance to the use of SIFTS in its original application of inland saline water bodies and also to those land-based aquaculture systems that generate high volumes of solid wastes.
Monitoring seal interactions – 2005/049As a direct result of this project and its outputs, fishers in the wet boat component of the Commonwealth Trawl Sector of the Southern and Eastern Scalefish and Shark Fishery (SESSF ) are now well informed about the identification, biology and conservation of seals; the potential impact of seal–fishery interactions; the importance of and need to record seal interactions and the correct way to do this. As part of this project the South East Trawl Fishing Industry Association (SETFIA) compiled an Industry Code of Practice to Minimise Interactions with Seals in 2007. All wet boats in the Commonwealth Trawl Sector of the SESF have a copy on board to ensure that skippers and crew have access to information on how to minimise seal bycatch and seal mortalities. The project has also established an industry-based monitoring and data collection program that resulted in a significant increase in fishers reporting seal–fishery interactions and fishers collecting samples from drowned seals. Validation options developed in the project can be used by industry to enhance the robustness of reported seal interactions. Through increased reporting and satisfactory validation of the industry-based monitoring program, industry will better meet the data collection and reporting standards for seal interactions required under the EPBC Act 1999 and the SESF Bycatch Action Plan. Information on the level of seal–fishery interactions will be analysed in 2009-10 once sufficient data has been collected.
Producing homozygous Pacific oysters – 2002/204The results from this study showed a high and highly variable genetic load (number of lethal equivalents) in Pacific Oysters, which was expressed progressively with larval development. On day 20 post-fertilisation the average number of lethal equivalents per individual was 11.5 or 15.0, according to the two methods used. This result highlighted the importance of avoiding inbreeding in order to maintain reliable commercial hatchery production. Inbreeding can be minimised by using a higher number of broodstock and/or broodstock with a clearly recorded pedigree history. Doubled haploid oyster larvae were produced by inhibiting the first mitotic division of eggs activated by UV irradiated sperm. The number of genetic markers required to differentiate doubled haploid progenies from meiotic II gynogens can be calculated by the equations developed in the present study. Detecting contamination from meiotic gynogenetic progenies is the major challenge to production of doubled haploids in aquaculture species.
Sustainable finfish culture technologies – 2005/213The project showed that yields of 10 tonnes of fish per hectare cannot be sustainably achieved in static, autotrophic saline ponds (that is, ponds dominated by photosynthetic organisms) over a three to four-month production cycle, despite the removal of settable wastes from the semiintensive floating tank system (SIFTS ). The outcome of this finding was to advise potential industry entrants of this fact and to further investigate alternative options to enable such yields to be achieved. The project’s work on integrating heterotrophic pond-management techniques (that is, ponds dominated by bacterial organisms that use organic carbon as an energy source) with carnivorous fish production in SIFTS has shown that 15 tonnes per hectare is achievable over a 100-day production cycle. Economic analysis revealed that the profitability of a stand-alone enterprise growing carnivorous fish in SIFTS within heterotrophic ponds would be marginal at 150 tonnes per year of production. The outcomes of these trials have already been used to design further trials on optimising heterotrophic pond management at the Queensland Department of Primary Industries’ Bribie Island Aquaculture Research Centre. Demonstrating that SIFTS can be integrated with heterotrophic pondmanagement systems creates an opportunity for existing prawn farms using heterotrophic pond management to integrate Barramundi farming into their existing operations with minimal changes. |
