Need

This project is needed for three main reasons:

1. It directly addresses a NT RAC priority in the 2019 call for funding applications relating to improving sustainable yield estimates to inform stock assessment programs for undefined target species and protected species in the Offshore Net and Line Fishery. The project will support sustainable fishing practices for important commercial fisheries in the NT and the development of new commercial opportunities within these fisheries: The impacts of fishery activities on these species, either through bycatch or targeted harvest, are difficult to assess in the absence of information on population connectivity and stock structure.

2. The project will develop capacity for fisheries research and monitoring in NT waters. Genetics methods are widely applied to fisheries research and monitoring and training of an early career fisheries scientist in the application and interpretation of genetic data will be a key outcome of this project.

3. The project will provide key information to support the transition of these species from bycatch to a harvested byproduct species, including an evaluation of leading-edge genetic techniques in fisheries assessment and monitoring.

Objectives

1. To develop population connectivity model for Whitecheek and Milk Shark
2. To develop capacity for research and monitoring of shark species within the Northern Territory
3. To evaluate the utility of genetic techniques in fisheries monitoring

Summary

Charles Darwin University and the Northern Territory (NT) Department of Industry, Tourism and Trade (DITT) Fisheries Division used genetic data to investigate the population structure of two small tropical shark species (Milk Shark [Rhizoprionodon acutus] and Australian Blackspot Shark [Carcharhinus coatesi]), which are caught as bycatch from commercial fisheries in the NT. 
 
The aim of this study was to gain information on the genetic stock structure to inform the future management of these two species in the NT. This project was conducted in parallel with a PhD project investigating the biology and ecology of both species for applications to fisheries management. There is motivation by the NT Government to develop these two shark species into a commercial product. This project used genetic analysis to understand the patterns of connectivity of populations of these two shark species in NT waters and adjacent regions, including northern Western Australia and Papua New Guinea.
 
These two shark species that are captured as bycatch in the NT Demersal Fishery have the potential to be developed into a byproduct to add value to that fishery. A sustainable commercial harvest of these two species could greatly reduce the waste from fisheries, where they are currently abundant and caught in relatively large numbers. We address current knowledge gaps in biological information about populations of R. acutus and C. coatesi to inform the potential development of a byproduct fishery for these two species in the NT.
 
Genetic data from R. acutus and C. coatesi strongly suggest that each species exists as a single, highly connected population in the NT. Genetic differentiation among the sampling locations for each species was low, and genetic clustering analyses provided strong support for a single population of each species in the region. Sharks of both species captured within a single location (within 50 km of one another) were more genetically related than those further apart; however, this does not constitute evidence for multiple, spatially discrete populations of either species in NT waters. Preliminary applications of effective population size estimators were used, but further work is needed to determine if these can be used to indicate trends in abundance. 
 
The immediate implications of our research are for fisheries scientists and managers. Our results indicate that these two shark species can be monitored and managed in the NT under the assumption that each species occurs as a single population in this region. Parasite and vertebral chemistry data collected as part of a PhD project conducted in parallel with this project suggest that, for C. coatesi, individuals may be resident within certain regions (eastern versus western NT waters) but the genetic data collected here suggest that, on a generational timescale, both species occur as highly-connected populations across in the NT region. 
 
Our research has potential implications for commercial fishers, particularly from the NT Demersal Fishery. The information from our research will flow through to the industry by contributing to the information required to develop a byproduct fishery for the two species, by utilising bycatch and increasing economic return.

Need

The IRG has raised a need to synthesise the key messages from previous projects that they have supported. In order to ensure that the data and information from these projects are accessible and easily understood for various audiences (includes Indigenous, commercial and recreational stakeholders, researchers, policy makers and the general public), the IRG has identified a need to create succinct materials that can be useful to those that seek to develop policy and stimulate community driven engagement.

Objectives

1. To gain an understanding of the materials and formats that policy-makers and key fisheries organizations need in their utilization of research to develop policy.
2. To improve general stakeholder awareness of the key research findings in of FRDC and IRG projects.
3. To provide Aboriginal and Torres Strait Islander communities with material that they can use in their engagement with government and non-government agencies.
4. To develop a succinct fact-sheets and a report that integrate the key messages of eight previous IRG projects in a user-friendly and culturally appropriate way.

Summary

What the report is about
This project identifies, synthesises and summarises the key messages of eight projects that have been funded by the Fisheries Research and Development Corporation (FRDC) and the Indigenous Reference Group (IRG) on fisheries. These key messages have been presented through a series of materials including a synthesis report, summary booklets and an infographic, all of which were developed as a way of raising awareness of the latest research findings regarding the Indigenous fisheries in Australia. They are presented in a manner that is useful and accessible to a wide-range of audiences including Indigenous communities, decision makers and other fisheries stakeholders.
The materials have specifically developed with the aim of empowering Aboriginal and Torres Strait Islander communities by providing them with resources that they can use to engage government and non-government agencies. This project also involved a two-way learning component which entailed engaging an Indigenous student as a researcher for the duration of this project.
Background
In 2011 the Fisheries Research and Development Corporation (FRDC) and the Indigenous Reference Group (IRG) on fisheries held a national forum to discuss issues around Indigenous involvement in fishing and seafood based Research, Development and Extension (RD&E). Participants at the forum included Aboriginal and Torres Strait Islander people with experience or expertise in fishing, seafood, or natural resource management across Australia as well as a small number of non-Indigenous participants (Calogeras et al. 2012). In 2012, participants from the forum reviewed and endorsed the work and confirmed that the outputs and the outcomes aligned with the desires of the group. Through this process, the IRG developed a set of five priorities to guide RD&E for and about Indigenous fishing in Australia (Calogeras et al. 2012).
The FRDC-IRG have supported a number of projects focused on Aboriginal and Torres Strait Islander fisheries that focus on elements of the RD&E priorities (Calogeras et al. 2012). These projects have information that the IRG needs to communicate with Indigenous, commercial and recreational stakeholders, researchers, policy makers, agencies and the general public. Their findings bridge certain knowledge gaps about the Indigenous fisheries and highlight key issues and priorities of Indigenous fishing communities in terms of access and use of their fisheries.
Aims/objectives
This project was undertaken in response to the need identified by the IRG to ensure that the research findings from the previous eight projects are made accessible and easy to understand. The project consisted of the following objectives:
  1. To gain an understanding of the materials and formats that policy makers and key fisheries organisations need in their use of research to develop policy.
  2. To improve general stakeholder awareness of the key research findings in of FRDC and IRG projects.
  3. To provide Aboriginal and Torres Strait Islander communities with material that they can use in their engagement with government and non-government agencies.
  4. To develop succinct fact-sheets and a report that integrate the key messages of eight previous IRG projects in a user-friendly and culturally appropriate way.
Methodology
The project team conducted a desk-top review of eight project reports, their appendices, conducted phone meetings with the principle investigators of each project and liaised with the IRG. Project materials were subsequently developed with the use of qualitative data analysis software NVIVO and designed through Canva, a graphic design program.
Aboriginal or Torres Strait Islander artwork was used for the materials produced and where appropriate the artist engaged was from the region that the original project was for or about. An Indigenous student was also recruited as an employee of Land to Sea Consulting for the purposes of two-way capacity building.
Results/key findings
The project findings echo the key messages drawn from the eight recent FRDC-IRG projects that took place on country through participatory and ethical research methodologies. The five themes identified provide an insight into Indigenous priorities for:
  1. Indigenous fisheries
  2. Governance and management
  3. Legislation and policy
  4. Economic empowerment
  5. Capacity building
These five themes have been developed as a way of understanding the key messages of recent FRDC-IRG research and for providing a step forward in offering fisheries stakeholders with in-depth insights into the challenges and opportunities facing the Indigenous fisheries sector. They support and align with the IRG RD&E principles and priorities while emphasising the particular findings and core assertions of the research projects analysed.
Implications for relevant stakeholders
The significance of this project lies in the materials created to communicate with Indigenous communities, fisheries managers, policy makers and other stakeholders involved in the Australian fisheries. They are short, easy-to-read and accessible versions of eight comprehensive research projects and clearly summarise their findings and synthesise their key messages.
The also provide Indigenous communities with material that they can use to engage decision makers. For policy makers and managers, they provide a synthesised and summarised version of recent research bout Indigenous fisheries from which proactive policy can be built and based upon.
Recommendations
The five key messages that have been created through the synthesis of the FRDC-IRG projects have come to shape the very core of this project. Therefore, it is ultimately inevitable that these are the same messages that must embody the recommendations of this project. They are particularly aimed at policy makers and the direction for further development in the Indigenous fisheries sector.

Summary

Indigenous communities in Australia have utilised, shared and traded marine resources since time immemorial. These communities continue to hold strong connections and knowledge to aquatic ecosystems and biological resources, and fishing remains embedded in their cultural, social and economic lives.
Since the early stages of colonisation, the ability of Indigenous fishing communities to access their fisheries for both cultural and commercial purposes has been disrupted by external factors, including the policies and practices of the Australian state. In recent history international agreements have been put in place to protect Indigenous rights to access and manage their fisheries worldwide. The Australian government has an obligation to ensure the protection of Indigenous peoples access to their land and sea. Yet there still remains a gap in the aspirations of Indigenous community for their fisheries and formal fisheries management arrangements.
Presently, the Commonwealth, States and Territories define and recognise Indigenous fisheries through different legislation, policy and practices. In turn, there is an identified need for a comprehensive set of national principles to guide the development, implementation and monitoring of Indigenous fisheries policy across all jurisdictions.
The key messages that have been identified through the findings of recent FRDC-IRG research projects present opportunities for various levels of government to proactively assist and support Indigenous fishing communities to access and utilise their fisheries in ways that align with Indigenous aspirations.
