Need

Abalone Viral Ganglioneuritis (AVG) disease is caused by a herpesvirus (infection with abalone herpesvirus, AbHV) and was first detected in Victoria in December 2005. The last recorded instance of this disease in Victoria was in January 2010 at Cape Otway.

The disease was again confirmed in the Cape Nelson area on 2 May 2021. Since then, further detections have been made at several locations and has been confirmed in Victoria as far east as Cape Otway and as far west as the Discovery Bay Marine Park.

While the virus is active there is a need for the Victorian wild catch abalone fishers to urgently review past research, to inform a gap analysis and further research.

This review will support those involved in the outbreak and inform fellow members nationally with a summary of past research and a way forward with other research for up-to-date biosecurity protocols, surveillance, and diagnostic tools to aid rapid detection to future proof the industry. Relevant industry, government representatives and stakeholders will be kept informed and asked to comment and contribute issues and ideas for a cooperative structured way forward to build a common framework on which to establish a set of key actions and or priorities. At the end of a staged process a workshop will be organised to evaluate and reassess research needs, assess and implement research findings and if further gaps are identified develop a framework to action.

Objectives

1. Conduct an analysis of past research on AVG, create a plain English summary and identify knowledge and research gaps that can be evaluated nationally by key stakeholders
2. Hold a workshop that will be a mixture of face to face and virtual so that key stakeholders can attend and participate in evaluation of suggested research projects identified
3. Prepare and provide a final report that clearly articulates research priorities for AVG in the short term and long term

Summary

Following Abalone Viral Ganglioneurits (AVG) re-emerging in the Western Zone of the Victorian Abalone Fishery in early May 2021 it was decided that a workshop needed to be convened as soon as possible with relevant stakeholders to evaluate past research and understand research gaps while the virus is active, and samples of active material can be collected and stored in a secure laboratory in readiness for future testing. Stakeholders from wild catch Victoria, South Australia, Tasmania, and New South Wales; farmed abalone sector; government and research agencies and universities gathered for a 1-day workshop, held in Queenscliff on 14th December 2021 to identify and prioritise future research and development priorities.

Need

The Victorian Diver Observation System enables divers to use their mobile phone to report observations on stock abundance, catch rates and habitat changes. These observations are stored, analysed and reported back to authorised industry personnel in a manner suitable for stock assessment meetings. This project aims to customise and make available the Diver Observations System to participating jurisdictions. Extensive industry consultation, trials and investigation will lead to a final solution being recommended for a Diver Observation System beyond the life of this project.

Feedback from industry divers on stock levels, habitat and other factors that affect fishing activity are widely used to provide context to scientific data during stock assessment and management decision making. The predominate method for obtaining this feedback is through direct representation by divers at stock assessment workshops. There are several issues with this approach. Only divers present at the meeting have an opportunity to contribute, there may be disincentives to be honest with peers and employers also in the room, and recall may be inaccurate with time passed.

Fishery management departments and industry groups in other states are keen to utilize a diver observation survey on a cost- effective electronic data capture platform that provides greater opportunity for obtaining diver feedback.

In Victoria, diver observations are included in the multiple lines of evidence approach (e.g. catch per unit effort, independent surveys of abundance and size, industry-collected data) for setting the annual Total Allowable Commercial Catch (TACC) as detailed in the Victorian Wild Harvest Abalone Fishery Management Plan (DEDJTR 2015). The value of observation by divers cannot be underestimated for abalone management, as they witness the state of the resource at a fine scale and over time. Thus, there is a strong need to develop a tailored system for anonymous collection, analysis and reporting of abalone diver observations to better inform management decision making.

.

Objectives

1. Collaborate with industry in each jurisdiction to develop customised Diver Observation Surveys.
2. Collect, analyse and report diver observation data using an electronic system.
3. Validate Diver Observation data against gps logger data.
4. Develop a potential business model for the continuation of the Diver Observation System beyond the life of this project.

Summary

This project was an industry-led and highly collaborative project to develop a rigorous and cost-effective electronic platform to gather abalone divers’ observations of abalone stocks in situ that could be useful to inform the management of Australian abalone fisheries.
