Need

This project will provide for the first time, a platform for abalone divers to come together from different jurisdictions and exchange their wealth of knowledge, skills, and best practices with each other for the benefit of the Australian abalone industry. In addition to the objective of improving practices and building industry capacity and resilience, the project will also provide the opportunities for divers to network, build relationships, exchange ideas, and work toward other joint ventures.

While the Australian abalone industry is a highly collaborative fishing sector through industry peak bodies and associations, there is little-to-no interaction between divers across jurisdictions. Divers in the abalone industry historically do not necessarily have a voice or a mechanism to come together, to discuss and share their issues, their knowledge, operational skills and best practices. Yet divers are the custodians of the resource, are the eyes under the waters, and have extensive knowledge and expertise to share.

Given the current state of the industry and issues faced - for example strict quotas, descending TACCs, safety concerns, biosecurity concerns, increasing shark populations, environmental change, market fluctuations and opportunities, an aging industry - it is now critical for abalone divers to come together and exchange their knowledge for the benefit of all stakeholders in the Australian abalone industry and the fishery.

Each jurisdiction has its own strengths and weaknesses. For example, Victoria is a leader in industry-led data collection and safety, Tasmania leads on value-adding to the product, and Western Australia is current leaders in shark mitigation. The purpose of the project is to share these strengths with each other. The project will also utilise industry expertise and contacts in key strength areas. For example, fisheries scientists, health practitioners, processing and marketing sectors.

The most important part of this project is that it is diver-led, which will ensure industry participation, and that it will contain relevant and appropriate content for divers.

Objectives

1. To facilitate improved knowledge exchange between Australian abalone divers across jurisdictions
2. To build collaboration and exchange knowledge between divers, experts, and stakeholders across all abalone fishing jurisdictions
3. To deliver appropriate dissemination materials which are accessible to all Australian abalone divers
4. To review the AWA® Quality Assurance Code of Practice

Need

Abalone Viral Ganglioneuritis (AVG) was first observed causing catastrophic mortality of abalone in western Victoria during May 2006, and continued to spread. As a consequence, there was a large reduction in Total Allowable Catch with consequent reductions in GVP of the Industry and its profitability. Further, the AVG-related mortality led to great uncertainty about the status of the abalone populations (e.g. depletion) and its productive ability (e.g. catch). Populations affected by AVG were closed to fishing for 3-5 years, and have gradually been re-opened through a process involving fishery-independent abundance surveys, biomass estimates and structured fishing to deliver information about stocks. Combined with routine monitoring, a substantial amount of data has now been collected about the on-going recovery of abalone stocks to inform their management.

Prior to AVG, WADA developed a process for finer scale assessment and management advice for the fishery. Workshops with significant Industry input and consideration of fine scale stock assessment are now used in most state's abalone fishery. With the reestablishment of fishing in western Victoria, and greater information about the productive capacity of the stock, there is now a strong need to consolidate the data available and develop their interpretation as performance indicators for the fishery. An important component of this will include the use of the performance indicators in developing flexible decision criteria and investigating scenarios of recovery for the fishery from a population model, updating earlier scenarios generated prior to the resumption of fishing. The Victorian Central Zone fishery has also been impacted by AVG, and will also benefit from greater coordination of the data available from multiple sources and its interpretation as fishery performance indicators with flexible decision criteria, as part of their TAC setting process

Objectives

1. Facilitate a workshop to consolidate existing data, review analysis, interpretation and use as performance indicators in the TAC setting process, including development of a future monitoring plan.
2. Implement the short-term outcomes of the workshop, particularly related to development of the performance indicators, their use in updating population model scenarios of recovery, and combination in the TAC Setting process.

Summary

Management Strategy Evaluation (MSE) methods are used to examine the performance of prospective Harvest Control Rules for calculating the Total Allowable Catch (TAC) for the Western Zone (WZ) Abalone Fishery. Of particular importance is recovery of the stock following the combined effects of previous fishing and Abalone Viral Ganglioneuritis (AVG) mortality in 2006/7.
