An example from Tasmania is the recent contamination of Macquarie Harbour, whereby tailings from Copper Mines Tasmania (CMT) dam in Queenstown entered the harbour and undoubtedly caused environmental harm to salmon and other species. Because CMT and salmon farmers operate under different Acts CMT was not responsible for the incident but rather the government. Consequently, no investigation or clean-up ensued.
Additionally, the scope of statutory tools, such as EIS under the Tasmanian Marine Farm Planning Act 1995, is not regional and does not consider the compound interactions of and on production activities. A good example is the recent Storm Bay salmon farming expansion; while the EPBC listed handfish species in Tasmania were listed in the marine farming development plan, with a brief context, management of these species was not considered in the EIS because that process only includes direct impact of the lease position. Arguably, cumulative impacts from all development in the area will have varying impacts on the species, impacts which are not being considered under current government legislation, but are potentially the source of public ire.
For aquaculture to pursue sustainable efforts environmentally, economically and socially in the increasingly crowded near shore space requires proactive planning and transparency that is not currently possible given existing assessment tools. In particular, assessment of cumulative impacts must be addressed. Cumulative impact assessments (CIA) are gaining momentum across multiple industries due to a recognised need to apply them in the pursuit of sustainable management. CIAs are being undertaken with the protection of marines resources at front of mind, but so far there has been little consideration of aquaculture. An approach to CIA that makes aquaculture the centre point is required if we are to consider its impacts or conversely, its effectiveness. Objectives: 1. Identify the risks of multiple actions or impacts on the environment and social values of a marine production matrix in Australian waters. In order to do this a comprehensive literature review is required to develop the CIA approach and ensure the methods and gaps in aquaculture CIA are addressed to meet the needs of Australian aquaculture, the community and the consumer. 2. Develop a risk assessment tool that can be utilised by the public realm (governments at all levels, NFPS, community) to better understand the complexities of regional marine waters and user impacts to maximise current and future economic, social and environmental benefits. To do this requires identification of valued environmental and social components first, whereby such components are characterised, from this a framework is build on each valued component. 3. Assess aquaculture in the context of broader social and environmental issues within the marine production matrix, by performing an aquaculture specific cumulative impacts assessment for regional Australia Read moreRead less

NT Fisheries has been conducting research to support Aboriginal aspirations to establish tropical oyster farms in the Northern Territory (NT).
Heavy metals have been a longstanding concern as an impediment to the development of a tropical oyster industry. Cadmium (Cd) bioaccumulates in the tissue of oysters, and unlike E. coli or toxic algae, has a long depuration period. As a result Cd levels are a major determining factor on the saleability of farmed tropical oysters. McConchie, D.M & Lawrance, L.M (1991) and FRDC Project 2012-223 identified high Cd concentrations, which varied considerably across locations and water depth, in blacklip oysters (Saccostrea echinata) at location in Shark Bay, WA and South Goulburn Island, NT respectively. Following these projects naturally occurring heavy metals have been a presumed barrier to the establishment of an oyster industry in the NT, due predominantly to the exceedance of Cd trigger levels in the Food Standards Australia and New Zealand (FSANZ).
However, recent testing on market sized oysters farmed on long line trials at Pirlangimpi on Tiwi Islands have not shown high heavy metal concentrations and complied with the FSANZ. This suggests that Cd exceedance may not be an issue in all locations. We propose a multi-location survey of blacklip oyster (Saccostrea echinata) heavy metal concentrations across the NT to identify the best locations for commercialisation of this emerging aquaculture species. With the aim of identifying locations, like Pirlangimpi, that could produce oysters that comply with the Food Standards Australia and New Zealand (FSANZ). The results are needed to inform the development of a NT tropical oyster industry and the establishment of a NT shellfish quality assurance program. Objectives: 1. Map the distribution and concentration of Cadmium in wild blacklip oysters across the Northern Territory. 2. Aboriginal communities better understand the role of shellfish quality assurance programs and the implications of Cadmium on oyster farming. 3. Risks associated with Cadmium are better understood and inform the development of a NT Shellfish Quality Assurance Program. 4. Knowledge is shared and retained through Aboriginal participation in the research project. Read moreRead less

Summary
In Western Australia, the positive and negative effects of SGD in marine benthic communities remains unknown. In Marmion Lagoon, SGD is known to supply up to 50% of the nutrients required for the macrophyte growth rates observed (Johannes and Hearn 1985). Freshwater input has been observed to positively impact seagrass germination (Xu et al., 2016), and although no similar studies exist for temperate seagrass species in the southern hemisphere, SGD may have a role in the creation, maintenance an ....In Western Australia, the positive and negative effects of SGD in marine benthic communities remains unknown. In Marmion Lagoon, SGD is known to supply up to 50% of the nutrients required for the macrophyte growth rates observed (Johannes and Hearn 1985). Freshwater input has been observed to positively impact seagrass germination (Xu et al., 2016), and although no similar studies exist for temperate seagrass species in the southern hemisphere, SGD may have a role in the creation, maintenance and augmentation of seagrass beds. The direct influence of SGD on puerulus settlement rates is unknown but freshwater discharge has been shown to be positively correlated with crab larval abundance (Boylan and Wenner, 1993). An ongoing FRDC project (2016-260: Assess causes and implications of anomalous low lobster catch rates) has demonstrated post-puerulus western rock lobster exhibit a strong choice for the chemical signature of seagrass (Brooker et al. in prep). These findings suggest that SGD may affect puerulus settlement rates either directly through chemotaxis or indirectly by impacting the density of seagrass meadows. Hence, there is a need to investigate both the role of SGD and the presence of seagrass on puerulus settlement rates. Land derived contaminants potentially impacting puerulus settlement and survival could include heavy metals and endocrine disrupting chemicals, such as flame-retardants or pesticides targeting insects (McKenney, 1999). Adult lobster have been shown to be repelled by the presence of copper (McLeese, 1975) and both flame-retardants (polybrominated diphenyl ethers - PBDEs) (Davies and Zou, 2012) and various insecticides (Ghekiere et al., 2005) have been shown to disrupt moulting in marine crustacea. Alkylphenol pollution was implicated in a major die-off of the American lobster (Homarus americanus) population that occurred in Long Island Sound in 1999, with acute impact on post-puerulus mortality during moulting (Laufer et al., 2013). There is a need to investigate both the occurrence and concentration of likely contaminants at potential source locations within the Western Rock Lobster fishery and assess their impact on post-puerulus survival.
Objectives: 1. Identify areas of significant submarine groundwater discharge (SGD) nearby established western rock lobster settlement monitoring sites. 2. Investigate the direct role of SGD on western rock lobster settlement rates. 3. Investigate the link between SGD and the extent and condition of important lobster habitat (e.g. seagrass). 4. Identify and map input of contaminants by SGD in key fishery areas. 5. Investigate impact of contaminants on the survival of puerulus and post-puerulus lobster. Read moreRead less

The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy. Currently, the knowledge of the chemicals in these products is limited but we need to ensure that they are safe and do not unnecessarily contaminate resource recovery streams. It is expected that this project will develop a framework that could be used by industry and government to prevent chemicals of concern persisting in a circular economy, providing environmental and economic benefits through reduced risk of chemical exposure and unnecessary remediation costs.Read moreRead less

Per- and polyfluoroalkyl substances (PFAS) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans. Due to their non-stick, water and stain repellences, PFAS have long been used in everyday products (food wrappers, carpets, furniture etc.) which end up in landfills. As it is currently unknown how PFAS move through the various components of landfill barriers, their fate and transport has become a priority for the regulators of Australia’s landfill sites according to the Australian 2018 PFAS National Environmental Management Plan. This research will determine PFAS transport through common clay barriers enhanced with proteins which have been shown to be an excellent sorbent for PFAS.Read moreRead less
