In order to secure the future of Australian wild-catch and aquaculture fisheries, it is increasingly clear that, alongside effective and responsible management and production, building and maintaining societal support is vital.
There are a number of recent examples in Australia where wild-catch and aquaculture fisheries have been threatened, even shut down, as a result of not having a ‘social license to operate’. This is despite having good ecological, economic and management credentials. Examples include: the 2016 closure of the Victorian small scale Port Phillip Bay net fishery as a result of pressure from the recreational fishing sector; the environmental controversy over mid-water trawling (‘super trawlers’) for small pelagic species despite scientifically-determined healthy stock status; and environmental non-governmental organisations (eNGOs) campaigns against Tassal’s proposed fish farm operations in Okehampton Bay on Tasmania’s east coast.
The wild-catch and aquaculture industries are increasingly and acutely aware of the need to garner societal support. But, they are unsure of how to address poor societal support at its root, who needs to be involved to address the problem, and effective pathways to improving societal support. From an industry perspective, there are gaps in knowledge in terms of 1) identifying the determinants of poor/high societal support; 2) identifying stakeholder groups to target who determine societal support and outcomes for wild-catch and aquaculture fisheries (e.g. other resource user groups, eNGOs, decision-makers and government, consumers, other publics); and 3) appropriate, effective and innovative pathways to improve societal support through engagement strategies and interventions.
However, there is a wealth of information available that is not directly or easily transferable currently. It requires collation and synthesis to address the knowledge gaps, including learnings from other industries, international wild-catch and aquaculture fisheries, as well as historical case studies of successes and failures within Australia. This project will draw together knowledge from existing literature and documentation and also use key informant interviews to address the above gaps.
1. To provide a nuanced definition of societal support for wild-catch and aquaculture fisheries in Australia
2. To identify determining factors (social, economic, environmental and political) affecting societal support for wild-catch and aquaculture fisheries in Australia
3. To identify means by which to detect, assess and monitor societal support for wild-catch and aquaculture fisheries in Australia using a risk-based approach

Australia’s wild-catch fisheries and aquaculture are increasingly attentive to the importance of having support from communities and stakeholders to ensure their future sustainability and prosperity. This project aimed to identify determinants of socially-supported wild-catch fisheries and aquaculture in Australia. This project was developed collaboratively with the Human Dimensions Research Subprogram and relevant industry stakeholders and extends previous FRDC projects by examining differential definitions and assessments of social acceptability.

SPECIES
Documenting and assessing the impact of fishing on bycatch is required for all rock lobster fisheries to enable the appropriate management of ecosystem interactions. This includes the requirements for EPBC Act reporting and jurisdictional reporting obligations. Bycatch information is currently collected in all Southern Rock Lobster Fisheries (SRLF), but improvements are required if the fisheries are to meet the standards required for rigorous certification such as by MSC. Aside from certification, performing below best practice represents a risk for these fisheries in community acceptance. Problem are not severe but there is nonetheless need for improvement, especially in valuable fisheries of this size.
Problems include poor quality of byproduct reporting in logbooks, a lack of combined assessments of bycatch risks across jurisdictions (in addition to cumulative impacts), reporting systems not consistent with standard and/or best practice (e.g. numbers vs weights), different risk-based assessment methods being used across jurisdictions, and no agreed / implemented approach for monitoring the status of species that are at moderate risk. Bycatch management ideally requires integration into the harvest strategy and this will be pursued through this project including by the development of reference points for relevant species. Additionally, there is a need for transparent reporting of bycatch and threatened, endangered and protected species (TEPS) to wider community stakeholders to communicate sustainable management of Southern Rock Lobster Fisheries.
1. To define consistent data collection methodology of bycatch and TEPS that is best practice and can be verified across South Australia, Victoria and Tasmania.
2. To do a risk assessment pooled across all jurisdictions which will comprise all current information on bycatch and TEPS in SRLF.
3. To develop best practice ongoing reporting for SRLF emphasising the high risk species identified from objective 2.
4. To do stock assessments of selected byproduct species ranked at high risk in objective 2, using data-poor stock assessment methods.
5. To provide guidance around establishment of appropriate performance indicators for moderate and high risk bycatch and associated management strategies.

Bycatch is an important issue in fisheries worldwide, with the impacts of fishing activities on non-targeted species and the wider marine environment receiving increasing public attention. Issues such as the potential wastage of resources through discarding of unwanted catch, ecological impacts on non-targeted species and the possibility of negative impacts on Threatened Endangered and Protected Species (TEPS) have led to an expectation that government and other managers will report on the status and impacts on these species. In order to do this effectively, well designed monitoring programs need to be in place. Effective bycatch monitoring programs allow researchers to understand which species are important as bycatch across a fishery, how the quantity of bycatch is changing through time, and any potential risks to bycatch species.
This report provides the most in-depth analysis of bycatch across the entire Southern Rock Lobster Fishery (SRLF) to date, involving researchers, stakeholders and managers across South Australia, Victoria and Tasmania. We use information from independent scientific observer programs and scientific research cruises collected over a period of greater than 15 years to:
- Explore the important bycatch species in each state and management zone;
- Conduct a critical appraisal of the current monitoring programs by comparing them to international best practice;
- Help inform a risk assessment for all bycatch species through workshops held in each state involving key stakeholders including researchers, fishers, fisheries managers, scientific observers involved in the monitoring programs, scientific experts and ecologists.;
- Explore quantities and trends in bycatch for species deemed to be at moderate risk from fishing activities.
Important bycatch species in terms of frequency, total number and weight varied across the states and management zones but generally included wrasse, leatherjackets, perch, octopus, crabs (hermit, velvet and giant) and sharks (Draughtboard Sharks in Tasmania and Eastern Victoria, and Port Jackson Sharks in Western Victoria and South Australia). Undersized Rock Lobsters, which are also considered bycatch, formed a large component of the overall bycatch particularly in Tasmania.
The current bycatch monitoring program was assessed against international best standards defined under the United States Tier Classification Scheme developed by the National Marine Fisheries Service. We found that each state managed program fell into a Tier 2 classification out of five possible tiers ranging from 0 to 5. This score was reasonable when comparing the programs in other fisheries given the size of the SRLF. However, areas for improvement in the observer programs were identified and recommendations on how to improve the ongoing monitoring program are made in light of our findings.
The risk assessment found that no bycatch species was at high risk from fishery operations of the SRLF. Species that were identified as having a medium potential risk were a subset of those that are kept as byproduct either for consumption, sale or bait. Barotrauma was also identified as a risk factor for some finfish species with swim bladders as these species when brought up from depth may suffer injury or be unable to descend and thus more susceptible to predation. Also, missing life history information for a number of species meant that precautionary higher risk scores were assigned to these species until more information is obtained. Rates of encounter with gear of Threatened, Endangered and Protected Species (TEPS) were found to be low, and consequently direct threats from fishery operations likely to be low; however, ongoing monitoring of TEPS interactions is a necessary component of best practice.
A short list of ten species identified as being more susceptible to risk from the SRLF were given further analyses. These ten species included Draughtboard Shark, a number of leatherjacket species, Ocean Perch, Blue-throat Wrasse and Conger Eel. Analysis of these species and groups allowed for estimates of total catch of these species and trends in catch through time. These estimates provide a baseline for ongoing monitoring and the setting of reference points for management action for these species.
Based on the findings of this report, it is recommended that:
- Improvements are made to the observer programs including increasing the number of vessels participating, creation of consistent reporting methods, improved species identification
- Information is collected for bycatch species with missing life history parameters to allow increased confidence in future risk assessments
- Species identified in this report as being of primary or secondary importance as bycatch in the SRLF are prioritised for ongoing reporting and monitoring, with a periodic census of all bycatch species (perhaps every 5 years) used to detect any trends in overall bycatch composition
- Due to the considerable noise in bycatch data, longer-term trends are used as management trigger points
- Further research is conducted into reducing the amount of undersized Rock Lobster
