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.
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

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.
Investigating the use of a remote operated underwater vehicle (ROUV) for surveying abalone on reefs in the Western zone abalone fishery, Victoria.

There are areas of the Western Zone Abalone Fishery where Greenlip Abalone are depleting, with biomass levels well below carrying capacity and historical levels. Some areas may not recover quickly without intervention and recovery may be further impeded by climate change. Thus, the Western Zone wild-catch abalone industry is seeking to establish a commercial-scale stock release program to accelerate Greenlip Abalone stock recovery in South Australia using release of hatchery-reared juveniles. The Central Zone wild-catch abalone industry is seeking to establish a commercial-scale stock release program to re-build Greenlip Abalone stocks in depleted areas that will use hatchery-reared juveniles.
There are two key needs for commencing a stock recovery program using hatchery-reared juveniles. The key industry need is to test release of juvenile Greenlip Abalone in the Western and Central Zones to evaluate the long-term economic viability. To support this important industry goal, the key Government need is for data to underpin release policy. This includes knowledge of the geographic distribution of Greenlip Abalone genetic differentiation (after Miller et al. 2014, Sandoval-Castillo et al. 2017), to inform policy review.

1. Use single nucleotide polymorphism (SNPs

2. Assess the genetic suitability of using FX abalone for release into wild populations at sites across the SA Western Zone Fishery, ensuring that the genetic structure and diversity of wild populations is maintained, including an expert-based, genetics risk assessment workshop
3. Undertake a preliminary cost-benefit analysis to inform 'stop/go’ decision

Most jurisdictions have developed and used various combinations of indicators in stock assessment and TAC setting of their abalone fishery. Applications often use a time series of commercial catch rate or FIS density to detect trends and identify reference points of stock status. The use of fishery dependent indicators from logbooks and GPS loggers have been criticized for their potential to be biased and insensitive (‘hyper-stable’) because of commercial selection of all observations that are made. As a consequence, Fishery Independent Surveys (FIS) have also been used in stock assessment, with varying coverage in all state’s abalone fisheries. However, FIS have also been criticized for their large cost and considerable uncertainty about how representative and useful the data is for intensely spatially-structured abalone fisheries (e.g. spatial mismatch of the FIS and the stock). FIS reviews in several states found variable relationships between FIS estimates and other indicators of the fishery.
Alternatively, both GPS loggers and FIS have considerable complementary strengths. GPS logger information has strengths of extensive fine-scale detail about catch (e.g. allowing spatial standardisation, that represents one of the main challenges to fishery dependent data) with good coverage of the fishery, while FIS have strengths of repeatable and local scale detail that is independent of the fishery.
The project will review data available from GPS loggers, catch records and FIS in WZ Victoria, with possible extension to other fisheries depending on data access and funding. Methods to calculate density and biomass from different sources of data will be consolidated and applied at different spatial scales, and the precision and statistical coherence of estimates compared. These comparisons will enable the development of criteria to improve design of FIS, logger programs and related observations, and recommendations and guidance on the use of indicators of legal density and biomass in fishery harvest strategies.
1. Use the Victorian Western Zone (and other fisheries data, where available) as a test-bed to develop and evaluate a new approach to calculating density and biomass indicators of exploitable abalone.
2. Consolidate methods to calculate indicators of local exploitable density from reported catch, GPS logger and fixed site survey observations.
3. Assess the consistency, accuracy and reliability of these new indicators, and their likely performance for management decisions
4. Develop and apply new methods to (i) calibrate logger-derived local density from overlap of local observations of loggers and surveys, (ii) use logger observations to estimate the area fished and to which the calibrated local density estimates could be extrapolated to apply, and (iii) combine the density and area estimates to give an index of exploitable biomass in the fished area.
5. Provide criteria for the design of surveys, logger programs and related observations (e.g. the spatial scale of catch reporting) to give calibrated logger density and biomass indicators.
6. Provide recommendations and guidance on the use of indicators of exploitable density and biomass in fishery harvest strategies.
7. Provide training to develop capacity to understand and implement the approach with logger data.

The objectives of this project are to use the Victorian Western Zone (WZ) abalone fishery to develop and evaluate a new approach to calculating abalone density and biomass indicators from the combination of three information sources. The three information sources are:
i. Logbook reported catch and effort,
ii. Global Positioning System (GPS) logger records plus depth and catch from fishers, and
iii. Fishery Independent Survey (FIS) observations collected by the government Victoria Fisheries Authority (VFA) and surveys done by the Western Abalone Divers Association (WADA).

ii. Global Positioning System (GPS) logger records plus depth and catch from fishers, and

This document provides a update on project progress to date, which has been mostly on reconciling the input data and replicating the analyses that were done historically to recommend a Total Allowable Commercial Catch (TACC) for the fishery.
