Fish and crustacean stocks are under pressure from a range of sources, such as a growing population, increased fishing pressure and anthropogenic changes. These pressures, and the small-scale nature of many fisheries in terms of their economic return, highlight the need to develop cost-effective tools for assessing and valuing these fisheries. Such tools should be able to estimate the social and economic contribution of commercial and recreational fisheries to communities (FRDC 2014/008). However, FRDC 2012/214 has highlighted that ‘poor quality data’ on the economic value of recreational and indigenous fishing limits the development of optimal policies for these fisheries. Advances in aquaculture provide ‘new’ options for managers and the ability to restore or enhance target populations by releasing cultured individuals. Increasing interest from recreational fishers in enhancing fishing experiences and the development of government policies for release programs in WA, NSW and Victoria, combined with the creation of Recreational Fishing Initiatives Funds (RFIF), have focussed attention on restocking/stock enhancement as a potential management option. To maximise the likelihood for success, tools are needed to evaluate the potential effectiveness of any release program in increasing target populations. Combining the results of release program bioeconomic models with social and economic data, such as the increased catch (revenue) generation for commercial fishers and the economic returns and social values of recreational fishing, provides managers with improved decision making abilities based on an understanding of the social and economic implications of those decisions. The ability to assess the social values and economic contributions of fisheries to communities also provides much needed information, particularly on the catch, effort and motivations of recreational fishers, which are currently lacking in WA and can be used in the harvest strategy component of the Marine Stewardship Council certification process and to develop social and economic performance indicators for fisheries (FRDC 2014/008). Recfishwest has committed $100,000 from the WA RFIF to this proposal in recognition of the need for this research.

The need for this project was identified at the National Forum (Cairns 2011) (see Principles 1,2,3,5,6,7,8,10 - FRDC 2010/401). While commercial and recreational fisher values are fairly well understood, Indigenous values remain elusive to the development of fishing management strategies and policies. Similarly, Indigenous engagement in contemporary fisheries remains limited. These gaps result from a paucity of documented information in a format accessible to fisheries managers, and a shortage of Indigenous leaders and practitioners seeking to engage in fisheries and fisheries management.

These challenges are recognised in national R&DE plans and by the national FRDC IRG in calls for research to facilitate greater Indigenous engagement in fisheries, as well as more effective inclusion of Indigenous livelihood values in fisheries planning. Livelihood values include social, cultural and economic components. Achieving the longer term national goal of a comprehensive assessment of Indigenous fishing effort and development of catch allocation models will require lead up investment in Indigenous capacity to engage, as well as in documenting Indigenous livelihood values in fishing.

Significant progress has been achieved in mapping Indigenous values and building Indigenous engagement in related areas of natural resource management - particularly in water planning and land and sea management. The Indigenous capacity and expertise from these endeavours are relevant to the challenge of improving engagement of Indigenous people and knowledge in contemporary fisheries. In short, this project brings together Indigenous and non-Indigenous expertise from successful Indigenous natural and cultural resource management endeavours to map Indigenous values of aquatic biological resources and build capacity for greater Indigenous participation in fisheries. Further changes to regulations regarding Indigenous access to fisheries have been foreshadowed in two of the jurisdictions during the timeframe of the study. As such the study may allow investigation of the impacts of these changes to Indigenous satisfaction with their level of engagement in fisheries management and fishing activity.

Local abalone populations can be severely depleted by a range of impacts, including loss of habitat from the spread of sea urchins, diseases such as AVG and Perkinsus, environmental change and theft. Many of these impacts have been increasing for over a decade, although impacts of sea urchins on abalone and reef habitats in the last 5 years have been spreading in eastern Victoria, and appear related to climate change. Similarly, impacts remain from the spread of AVG through western Victoria.

There is evidence that production from commercial abalone fisheries continues to be reduced by the ongoing increase in external impacts to local abalone populations. While tools have been developed at a small-scale to help recover abalone populations, there is a strong need to investigate, implement and assess these at a larger scale to be able to minimise further impacts and recover productivity of abalone populations.

VicFRAB this year rated its highest priority to facilitate the investigation of translocating abalone to address declines caused by urchins and disease. Similarly, the NSW DPI strategic research plan identifies a priority to "determine methods to restore depleted reefs of abalone through techniques such as transplants, habitat rehabilitation and reseeding". The ACA Strategic Plan also details actions to plan and support remedial action to reduce the impact of pests, disease and theft on abalone.

The ongoing spread of impacts to local abalone populations is having a broad impact on shallow reef habitats. Small-scale research has demonstrated the potential of recovery techniques, but have not been implemented at a broad scale to actually attempt to recover lost productivity. This project will address the need to investigate the scaling up of recovery techniques, and their costs and long-term benefits, in an attempt to recovery lost productivity from abalone populations in south east Australia.
