Summary
Jellyfish blooms disrupt commercial fisheries around the world and blooms are increasing in frequency and magnitude in some regions (Condon, Pitt et al. 2013). Although the causes of jellyfish blooms are debated, they are frequently linked to anthropogenic pressures, including eutrophication, expansion of coastal infrastructure, and climate change (Pitt et al. 2018). The current jellyfish bloom in the Hawkesbury estuary is more extensive, persistent, and disruptive than previous blooms and .... Jellyfish blooms disrupt commercial fisheries around the world and blooms are increasing in frequency and magnitude in some regions (Condon, Pitt et al. 2013). Although the causes of jellyfish blooms are debated, they are frequently linked to anthropogenic pressures, including eutrophication, expansion of coastal infrastructure, and climate change (Pitt et al. 2018). The current jellyfish bloom in the Hawkesbury estuary is more extensive, persistent, and disruptive than previous blooms and may represent a long-term and sustained change to fishing conditions in the estuary. Some fishers have said they will leave the industry if blooms persist, hence this project is needed to reduce interactions between jellyfish and commercial net fishers and ensure the on-going viability of commercial net fisheries in the Hawkesbury.
The project specifically addresses the FRDC priority call for "Understanding the drivers of jellyfish blooms in the Hawkesbury". We will review the scientific literature and analyse existing data sets on water quality and jellyfish to identify probable environmental drivers of jellyfish blooms in the Hawkesbury estuary, which will enable estuary managers to prioritise which environmental conditions to manage to reduce jellyfish blooms. We will search for novel technical solutions (such as modifying fishing times or locations) that could reduce by-catch of jellyfish, assess potential ways to actively manage jellyfish (through their extraction or biological control), and co-design a long-term jellyfish monitoring program based on world best-practice with estuary managers and fishers to initiate the long-term collection of jellyfish data by stakeholders, which is essential for understanding jellyfish population dynamics and developing predictive models for jellyfish.
The drivers of jellyfish blooms in the Hawkesbury estuary may be linked to recent major floods. Floods are predicted to become more extreme and frequent under climate change. Hence our proposal aligns with FRDC's strategic investment opportunity for improving resilience of fishing in a changing climate. By providing information critical for managing jellyfish populations, our project also meets FRDC's F&D Plan Outcome 1 to "expand environmental management to cover areas other than stock status of target species". Through recruitment, mentoring and career development of a research fellow, our project builds capacity and capability of Australia's fisheries research and development sector (FRDC Enabling strategy IV).
Objectives: 1. Review the environmental drivers of jellyfish blooms, methods used by commercial fishers to manage interactions with jellyfish and methods that could be used to control jellyfish populations. 2. Collate and analyse existing data sets on water quality and jellyfish to identify potential drivers of jellyfish populations 3. Review jellyfish monitoring programs and co-design with stakeholders a fit-for-purpose and on-going jellyfish monitoring program for the Hawkesbury estuary 4. Engage stakeholders to locate relevant data sets and disseminate findings to end-users and beneficiaries Read moreRead less

Summary
The 5 July 2017 meeting of representatives from the various States involved in the Murray Cod industry agreed to three key R&D priorities to support expansion of the Murray Cod industry in Australia. They included:
1. Development of a farm management plan/manual to: provide advice on optimising production systems and water quality; review and update of existing Murray Cod culture guidelines using recent relevant publications and input from commercial operators; and identify any informa ....The 5 July 2017 meeting of representatives from the various States involved in the Murray Cod industry agreed to three key R&D priorities to support expansion of the Murray Cod industry in Australia. They included:
1. Development of a farm management plan/manual to: provide advice on optimising production systems and water quality; review and update of existing Murray Cod culture guidelines using recent relevant publications and input from commercial operators; and identify any information gaps 2. Off Flavour. Review of recent publications/work from other sectors (eg Barramundi) to prevent off flavor in Murray Cod. Murray Cod quality product assurance; and 3. Fish health and treatment (parasites, bacterial infection, Lurnea, Chilodonella, ratty tail). Review and update information on treatment options (chronic/prophylactic) for Murray Cod. Murray Cod health management strategy
This project proposal aims to address these high R&D industry priorities by developing a range of technical and extension material.
The Murray Cod industry is developing rapidly in Australia increasing from 250t 2014/15 to over 500t 2016/17. Industry forecast several thousand tonnes production by 2020 with many new farms seeking approval and new franchise business models moving forward. To capitalise on this expansion, there is a pressing need to improve extension resources.
Objectives: 1. Development of best practice production guidelines for Murray Cod aquaculture, to be used nationally 2. Extension to industry, and new investors, of the best practice production guidelines Read moreRead less

Summary
Soft flesh due to infection with myxosporean parasites irreversibly reduces the quality and market value of fish. Due to the delayed onset of the condition, infected fish can reach the consumer before soft flesh is detected, causing wastage, economic losses to affected fishers, and loss of consumer confidence.
Rapid onsite detection of myxosporean infection is vital to maximise value of landed fish, minimise environmental impacts associated with animal protein wastage, and increase prod ....Soft flesh due to infection with myxosporean parasites irreversibly reduces the quality and market value of fish. Due to the delayed onset of the condition, infected fish can reach the consumer before soft flesh is detected, causing wastage, economic losses to affected fishers, and loss of consumer confidence.
Rapid onsite detection of myxosporean infection is vital to maximise value of landed fish, minimise environmental impacts associated with animal protein wastage, and increase productivity for NSW commercial fishers, NSW fishers cooperatives and relevant fish markets.
This project focuses on outcome 2 of FRDC’s R&D plan – best practices and production systems. Fast and accurate detection of pathogens help industry identify risks faster and make informed decisions to refine and optimise best practices and production systems. There will be several benefits and impacts on society, environment, and the economy, including:
Society - fisheries productivity affects livelihoods of people working in the industry and its associated sectors - healthy and sustainable food resources Environment - reduce wastage Economic - increasing productivity through higher yields and higher market value - enhancing food/protein production improves food security and creates more employment opportunities Objectives: 1. To develop and evaluate PCR-based diagnostic tools for quantitative detection of myxosporeans in Mahi Mahi and Yellowtail Kingfish 2.

Environmental-Social-Governance (ESG) metrics are marketed as measures of environmental performance, but they often track exposure to environmental risk rather than generation of environmental impacts. This project aims to develop and test a science-based, systemic environmental impact score for corporate activities. Expected outcomes include new knowledge of cross-scale interactions in the Earth system and tools to assess a business or investment’s systemic environmental impacts from activities including water extraction, deforestation and carbon emissions. These outcomes should provide benefits including improved business decision-making on impact mitigation, environmental quality, productivity and corporate environmental reputation.Read moreRead less
