Growth figures from 2012 until now effectively doubled year on year, with the total production from 2019/2020 season estimated to be around 516 tonnes with an industry value of around $9.2 million (AUD). With this increased production and forecast to reach a $50 million dollar sector by 2030, it is imperative that feeds for Murray cod are tailored and bespoke to reach their full potential. The development of bespoke feeds for the sector will have the added benefit of improving the economics of operations from both a growth performance and feed efficiency perspective.
Noting that past research on Murray cod primarily by researchers at the Deakin University was very successful in demonstrating some core aspects of fish nutrition, it remains to be determined what benefits are possible on larger fish size classes which represent the bulk of feed consumed. In other well studied species such as Atlantic salmon and barramundi, gains in production efficiency can be achieved by diet design, with incremental changes improving the profitability throughout the life cycle. Although there is no co-op or association for growers, a recently commissioned report has highlighted the need for improved feeds and key R&D support for the sector is required. The proposed project aims to address some of the fundamental gaps in Murray cod nutrition on large size classes to identify where gains in production efficiency can realistically be achieved. Objectives: 1. Determine a baseline for the most optimal macronutrient levels (principally protein and lipid) for medium and large Murray cod in extruded diets. 2. Understand the nutrient profile of the feed types and how this affects the fish performance. 3. Conduct a series of laboratory analyses to determine the biometric and biochemical effect of the feed.

At both global and national levels, organisations are advocating for health to be considered in all policy (WHO, 2013). The objectives of the proposed research are to understand from an Indigenous knowledge domain the nutritional health and wellbeing benefits of seafood. This information can therefore support future considerations of nutrition and health benefits in policy and ensure that health and related unintentional impacts of policies are at least considered in the policy making process in fisheries development. There is an ongoing need for Indigenous grounded approaches to be implemented to improve the diet and nutritional programs in Aboriginal communities (e.g. government programs, Aboriginal Health organisations and school nutrition). It is anticipated that this research will be relevant to a wide range of stakeholders involved in addressing the nutritional and health outcomes in communities through promotion of seafood in diets. The western biomedical health benefits of seafood are widely known globally and nationally (FRDC, 2004). However, the relationships between Indigenous health and wellbeing and seafood in an Indigenous knowledge domain is not well understood. The proposed research aims to address this knowledge gap though a multidimensional approach including localised documentation and representation of Indigenous knowledges of the nutritional health and wellbeing benefits values and meanings of seafood and nutritional analysis of fish and seafood species. This approach will bring together two knowledges in a culturally appropriate manner to better promote a holistic understanding of nutritional benefits of seafood.
The outcome of the research will contribute new knowledge to ensure the development of Indigenous fisheries is sensitive to health, nutritional and wellbeing values and meanings of culturally important seafood. This research project is funded by the Fisheries Research Development Corporation (FRDC project 2019-143) on behalf of the Australian Government and is being implemented in partnership with Monash University, Charles Darwin University and Bawinanga Aboriginal Corporation and Traditional Aboriginal Owners from the Maningrida region in the Northern Territory. Project investigators are Associate Professor Julie Brimblecombe, Associate Professor Natasha Stacey, and PhD candidate Beau Cubillo.
Objectives: 1. To document Indigenous knowledges on the understanding of the nutritional health and wellbeing benefits and the value and meanings of locally caught and consumed seafood 2. To develop outputs (e.g. poster, booklet) based on Aboriginal knowledge and nutrition profiling of identified seafood species for inter-generational knowledge transfer 3. To develop a conceptual framework to bring together and represent the components and values of Indigenous knowledges of the nutritional health and wellbeing benefits of seafood Read moreRead less

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

Moreton Bay is a 1,500 km-squared urbanised estuary adjacent to one of the fastest growing regions in Australia. Rapid population growth creates a challenge for wastewater utilities to deal with the increase in nutrient loads. This includes the single largest asset of Queensland Urban Utilities (QUU), the Luggage Point Sewage Treatment Plant, at the mouth of the Brisbane River that discharges into the bay. At the same time, on the eastern side of Moreton Bay, the Queensland rock oyster industry faces reduced productivity due to environmental change, disease and algal blooms, and challenges associated with the business risks presented by monoculture. Here, communities on Minjerribah (Nth Stradbroke Island) are also investigating new opportunities during their transition away from sand mining, and Quandamooka Yoolooburrabee Aboriginal Corporation (QYAC) has Native Title on a large tract of the Moreton Bay Marine Park, which to date is mostly unutilised.
Seaweed production offers a unique and timely solution to address some of the economic, environmental and social challenges in Moreton Bay. Seaweed farming is a “no-feed” form of aquaculture; it is zero waste and compatible with oyster farming and marine park zoning. Seaweeds grow quickly and strip nutrients from the water column, draw down carbon dioxide and can remove pollutants such as heavy metals. At the right scale, seaweed farming will reverse environmental change. Because of this, QUU and the University of the Sunshine Coast (USC) are evaluating how much nutrient can be extracted from the bay as an offset for their discharge licences, to avoid substantial capital investment in sewage treatment whilst delivering better environmental outcomes for each dollar spent.
At more than 25 million tonnes per year, seaweed is the largest marine crop in the world. Southeast Queensland is the perfect setting for developing a seaweed industry – ample light, warm water and existing aquaculture leases with farmers, such as Moreton Bay Rock Oysters (MBRO), seeking to diversify their production. Investing in seaweed production will create a new industry for our coastal communities with accountable environmental services and sustainable products.
Objectives: 1. Compare and contrast the nutrient offset and sequestration potential of target seaweeds in controlled experiments 2. Evaluate seaweed production systems using commercially available aquaculture equipment during the scale-up of target seaweeds 3. Determine the yield and properties of harvested seaweed from a year-round pilot production trial at two sites within Moreton Bay 4. Assess the potential effects of seaweed culture on water quality and adjacent marine animals and vegetation 5. Model the removal of nutrients, carbon and other pollutants and the offset capacity of seaweed farming for Moreton Bay Read moreRead less

However, if poorly planned, rapid expansion to meet the ever increasing demand for seafood brings with it an environmental risk associated with eutrophication and organic enrichment of the seabed, adversely affecting marine coastal ecosystems. Approximately 75-85% of the nitrogen discharged from finfish aquaculture is dissolved and dispersed to nearby habitats. A major spatial constraint on aquaculture in nearshore areas around much of Australia is the potential for these dispersed nutrients to negatively affect seagrasses. Seagrasses can be sensitive to increases in nitrogen, which can lead to habitat loss. This loss can have significant environmental and economic impacts with potential losses of ecosystem services including decreases in commercial and recreational fisheries catches, increases in sand instability and erosion, reduced biodiversity, loss of nitrogen assimilation and cycling, and loss of carbon sequestration.
In other situations, small increases in nutrients may have a positive effect on seagrasses, and thus it is not clear what the consequences of aquaculture derived nutrients will be. Subsequently, we can’t robustly determine the level of finfish aquaculture that can be sustainably supported by seagrass ecosystems. There is therefore a need to develop a process to determine the likelihood of seagrass growth (or loss) due to aquaculture derived nutrient inputs. This work will develop metrics that can be used in other aquaculture developments and in long-term regional monitoring.
Clean Seas Seafood Pty Ltd are developing a new lease for the sea-cage aquaculture of 4500 tonnes of yellowtail kingfish (YTK) in the Fitzgerald Bay region. The nearshore habitats throughout the region are dominated by long-lived Posidonia seagrass. While Fitzgerald Bay was the original focus of YTK aquaculture in SA, it has not been utilised for ~10 years, essentially giving us the potential to study this system prior to the commencement of aquaculture (currently planned for ~ July 2019), as well as while production is increasing, and it thus provides an ideal case study for assessing how to sustainably farm finfish in a seagrass dominated ecosystem.
Objectives: 1. Determine cost-effective approaches to assessing the influence of finfish aquaculture derived nutrients on seagrasses, and using Fitzgerald Bay as a case study, what that influence is. 2. Develop a predictive modelling ability to estimate carrying capacity and allow scenario analysis of future aquaculture development and how it might affect seagrasses, to allow managers to make informed decisions about where to place future developments, and how much to allow existing developments to expand. 3. Use Fitzgerald Bay as a case study to document seagrass condition using a range of metrics both before the commencement of finfish aquaculture, and once production has reached a substantial level. 4. Develop a range of cost-effective indicators for monitoring the effects of aquaculture on adjacent seagrass beds. Read moreRead less
