Need

1. Tracing lobster origin
The need for determining whether stable isotopes are a useful tool for diet analysis and identification of catch location is a priority for the SRL fishery. If proved useful, this technology will allow for rapid identification and isolation of stock abnormalities – such as toxic algal blooms, which has potential to save a lot of time and money for fisheries management.

2. Invasive urchin controls
If results show that small lobsters do predate on urchins, this will be important for informing stock rebuilding targets and reference points relative to urchin control. Primarily we could advise on whether urchin control targets and performance indicators should be based on total lobster biomass or only large lobster biomass. For example, if small lobsters (140mm CL) are found to actively predate on small urchins, the pressure to rebuild the large lobster biomass (>140mm CL) may be reduced. This could in turn help to adapt the rebuild strategy, in line with effective urchin control.

Objectives

1. To determine the level of stable isotope variation within individual lobster tissues (e.g. muscle vs shell) and identify a non-lethal and minimally destructive method of sampling for stable isotopes.
2. To describe lobster diet off eastern Tasmania and quantify the role of smaller lobsters (&lt
140mm CL) in the predation and control of Longspined Sea Urchin in Tasmania.
3. To ascertain if stable isotopes can be used to identify catch location of individual lobsters post-harvest across SE Australia

Improving performance of ITQ fisheries - Project activity paused

Project number: 2020-029
Project Status:

Need

Individual Transferable Quotas (ITQs) and Individual Transferable Effort (ITE) systems have been introduced to a wide range of Australian fisheries (FRDC 2017-159). Since 1985, forty-six ITQs have been introduced to a range of fisheries and can be found across all jurisdictions in Australia; six ITEs have also been introduced, mainly in prawn trawl fisheries. Such systems allocate shares or portions of a total allowable catch (TAC), or total allowable effort (TAE), between fishers, vessels, communities, or others with an interest in the fishery.

Experience shows that ITQs as generally designed and implemented have not always fully delivered promised outcomes, have had outcomes that were unintended and unwanted, and in some instances have resulted in outcomes that make it difficult for fisheries managers to deliver against other, in many cases non-economic, objectives of fisheries management. In some instances, these unintended and unwanted consequences may also have been inappropriately attributed to the ITQs/ITEs and may more be down to other drivers such as globalisation or changes in stock abundance.

Building on industry and management’s growing interest in improving ITQ-fishery outcomes (SRL Corporatisation Workshop, Melbourne Airport, October 2019) and on the findings of 2017-159, this work will aim to provide evidence-based advice to managers and industry on options to address any performance gaps or unintended and unwanted consequences, and the potential effects of any proposed interventions on the economic, social and environmental outcomes of ITQs as generally implemented in Australian fisheries. The scope of options will include industry-led private sector initiatives, as well as Government-led changes to management.

Objectives

1. Assess the effects of adoption and ongoing management of ITQs including consequences that flow from ITQs and the effects of the adoption on specific performance indicators.
2. Develop adaptive management options for existing ITQs that will assist in managing the impact of unintended and unwanted consequences.
3. Better support managers in planning for the mitigation and management of unintended and unwanted consequences over time, including the cost of implementing change.
4. Provide options to fishery managers and stakeholders to assist in the adjustment of existing fisheries management under ITQs to avoid, or mitigate, unintended and unwanted consequences and/or enhance unintended but positive consequences.

Summary

Following the Improving performance of ITQ fisheries Forum on September 28, 2023, decisions were made regarding the project's direction. Instead of proceeding to case studies, stakeholders acknowledged the importance of focusing on future research priorities for rights-based fisheries approaches. Actions include finalising project reports, seeking independent reviews, and enhancing stakeholder consultations. The upcoming four-year independent review of FRDC provides further opportunities for input. Efforts also involve aligning research priorities with end-users, improving project procedures, and addressing improvement areas through the mandated external independent review of FRDC.
