Summary

The snapper, Chrysophrys auratus, is an economically valuable common property resource that occurs in large numbers in New South Wales waters. Allegations of a resource decline in this major target species of both commercial and recreational fishermen have led to conflict over fishing access and levels of exploitation. In order to investigate claims of a resource decline, the Fishing Industry Research and Development Council funded a three year research project by New South Wales Agriculture and Fisheries.

Need

In October 2018, FRDC funded the first national workshop on tropical oyster aquaculture (Osborne, 2018). This successful event addressed a need to foster greater collaboration across the various projects and provide strategic direction to future research and development activities. Since then, significant progress has been made in tropical rock oyster RD&E, both in Australia and internationally, and work is underway across the tropics to further develop the industry (Nowland et al., 2019). To maintain momentum and continue to foster collaboration in this field, an International Tropical Rock Oyster Workshop will be hosted by NT Fisheries and The Pacific Community (SPC), supported by the Cooperative Research Centre for Developing Northern Australia (CRCNA), in the days before the World Aquaculture Conference 2023 in Darwin. The workshop will bring together a broad range of stakeholders to discuss the status and current knowledge of tropical oyster aquaculture research and development. This will provide an opportunity to share experiences and develop an international network for tropical oyster aquaculture. As well as to discuss and document current bottlenecks/issues confronting tropical oyster farming, such as; hatchery production, disease, grow-out technology and shellfish quality assurance.

This workshop is running alongside the World Aquaculture Conference 2023 in Darwin. The project team have identified key people in the region (commercial produces and Traditional Owners) that would add additional value to the workshop and the World Aquaculture Conference 2023. However, they do not have the means to fund their own attendance.

Workshop information
Date: Sunday 28th & Monday 29th May 2023
Location: Convention Centre, Darwin NT, Australia

Need

• Coping with the potential persistence of WSSV in Australian waters
It is important for farms in the WSD risk region, as well as those outside it, to have access to the necessary tools and reliable information that enables them to implement highly effective biosecurity measures when they become necessary.

• Industry white spot disease preparedness
Chemical treatment to remove residual vectors and/or destroy the pathogen is currently the only practical approach with potential to adequately reduce WSD biosecurity risk associated with influent farm water. When assessment indicates a high disease risk, farms will need to be confident that their biosecurity measures will be immediately effective.

• Appropriate guidelines for using trichlorfon
Currently there is no locally generated guideline for achieving effective application of trichlorfon that is based on directly applicable experimental data and prawn farm experience. The industry needs a set of guidelines that expand upon the basic APVMA use conditions and define the environmental factors and application parameters that will provide the greatest protection for Australian farm conditions.

• Gaps in information currently available
The available information does not provide substantiated details of trichlorfon treatment methods and outcomes. The Australian industry needs validated treatment methods and their effectiveness and biosecurity outcomes verified.

• Constraints on trichlorfon use during production
Using trichlorfon to treat top-up and exchange water during the production cycle is problematic for some farms due to the 12 day conditioning period required to ensure toxic residues are below the detectable limit before stock is exposed to the water. The potential to manipulate water quality parameters to accelerate residue degradation could make treatment throughout the cycle a more practical option.

• Continuation of permit to use trichlorfon
Documented evidence of outcomes and impacts of trichlorfon use on farms is needed to support an APVMA application to extend its use beyond the current MUP period ending 31 December 2021.

Objectives

1. Determine the efficacy of trichlorfon treatment for removal of crustaceans from farm influent water, and the rate of toxic residuals degradation, under a range of treatment circumstances experienced on prawn farms.
2. Provide the prawn grow-out sector with a practical guide for the optimal use of trichlorfon as a water biosecurity method.
3. Provide data for APVMA registration of trichlorfon use, including practical methods for reducing the withholding period for trichlorfon treated water.

Need

The indigenous development scholarship is part of the suite of professional development opportunities developed and managed through the FRDC people development program. This particular scholarship addresses the following objectives of the people development program 2008-2013:

Objective 1 Enhance industry leadership within all sectors
and; Objective 3 Provide opportunities for knowledge transfer and R&D adoption

The significant drivers identified in the FRDC people development program, addressed by this project
are:
- There is a shortage of industry leaders in all sectors of the fishing industry.
- There is an urgent need to develop people within all sectors who have the skills to effectively contribute to debate and policy development for significant challenges, including access to fish resources.
-Early career researchers and emerging industry leaders lack opportunities for formal mentoring and
professional development.
-There is a shortage of opportunities for people in industry to develop skills that are going to directly
improve business profitability and sustainability.
-The industry is geographically dispersed and fragmented, and needs opportunities to learn within and
across sectors.

Objectives

1. To provide one annual scholarship for an indigenous person
2. To encourage maximm benefit from the scholarship with a personalised learning program and mentoring
3. Support and encourage the development of sustainable and mutually beneficial relationships between emerging indigenous leaders and host organisations

Need

The introduction and spread of aquatic invasive species in freshwater and marine environments is a worldwide problem that is increasing in frequency. There are various pathways by which non-indigenous species are introduced and cause significant damage to coastal and freshwater ecosystems, and to the economies that depend upon them.

With increased development, population growth, and vessel traffic, opportunities for the introduction and establishment of invasive species to Northern Territory waterways are increasing. Industries threatened include commercial and recreational fishing, aquaculture, port services, shipping and tourism. Challenges associated with addressing these risks include the need to respond to changing risk factors; unregulated or illegal vessel activity; and remote locations.

The International Conference on Aquatic Invasive Species is held annually and is the most comprehensive international forum for the review of scientific knowledge; presentation of research; introduction of technological developments for prevention, monitoring and control; and discussion of policy, legislation and outreach initiatives to raise awareness of the impacts of aquatic invasive species and prevent new introductions.

Attendance at the conference will provide opportunities for cooperation and collaboration, and allow the Territory to benefit from the latest knowledge and experience of researchers and managers worldwide in the development and implementation of local programs to address emerging risks.

It is also intended to visit the Great Lakes region to learn from local experiences with the invasive Zebra mussel (Dreissena polymorpha), and the management, control and monitoring of this species.

Objectives

1. Gather information about invasive species prevention, management and emergency response strategies overseas.
2. Learn from experiences with the zebra mussel establishment and spread in the Great Lakes region.
3. Apply the knowledge gained from objectives 1 and 2 to aquatic biosecurity strategies in the Northern Territory.
4. Disseminate knowledge gained from objectives 1 and 2 to national committees including the National Introduced Marine Pest Coordination Group and the Consultative Committee on Introduced Marine Pest Emergencies.
5. Present a paper to the ICAIS conference on marine pest threats, vectors and management strategies in the Northern Territory (if abstract is accepted).

Need

The importance of quantitative assessment and linkage between freshwater flows and ecological outcomes has been increasingly recognised in recent years. Information is particularly lacking for estuarine fisheries in Australia. The CLLAMM region supports a significant local economy based on irrigation/agriculture/tourism and commercial/recreational fisheries. The region also has a high biodiversity value, recognised by Ramsar wetland and Living Murray Icon Site status. However, the economy and biodiversity values of the region are currently under threat due to the reduction in flows from abstraction upstream. A number of environmental flow and engineering options are currently being considered to help improve the social, economic and environmental values of the system including ecologically sustainable fisheries. However, there is a lack of biophysical system knowledge required to assess and predict the potential environmental benefits of the different management options. Knowledge gaps include flow-related fish ecology-critical for water management to enhance spawning/recruitment of native fish (key objective of the Environmental Management Plan).

In recent years, state/commonwealth policies on fisheries management have been developed to ensure ecological sustainability of fisheries. The Lakes&Coorong Fishery management plan has identified flows as an important issue impacting key commercial/recreational species (mulloway, black bream, flounder, callop and Goolwa cockle). However, there is little research on specific flow/habitat requirements of these fish. This knowledge gap was identified on a recent National Estuarine-Flows-Workshop. Quantitative data is needed to inform sustainable management of fisheries and water resources.

This project is mainly to address flow-related ecology of key fish species of commercial/recreational/conservation or ecological significance (black bream, greenback flounder, yellow-eye mullet, congolli and goby sp.) in the Murray Estuary&Coorong, with a focus on reproductive biology and recruitment processes; whilst complementary work will be undertaken to investigate fish movement/migration by Bronwyn Gillander under CLLAMMecology. PI will work in collaboration with Bronwyn and other CLLAMM researchers.

Objectives

1. To determine the distribution, relative abundance and size/age structure of key fish species (black bream, greenback flounder, yellow-eye mullet, congolli and a goby species) and how these relate to habitat and environmental conditions (eg salinity, water temperature, freshwater flow, turbidity, dissolved oxygen, food availability) in the Murray Estuary and Coorong.
2. To examine aspects of reproductive biology and influence of environmental conditions on spawning success of key species in the region.
3. To investigate the influence of environmental conditions (eg habitat, salinity, water quality, food availability) on critical life stages thus recruitment success of key species.
4. To investigate the relationship between freshwater flows (timing, quantity and duration) and recruitment success and fisheries production of key commercial species.
