The Gunaikurnai Land and Waters Aboriginal Corporation (GLaWAC) is exploring aquaculture development opportunities on country and in partnership with the VFA have commenced a small pilot trial of Sydney Rock oyster aquaculture in the Gippsland Lakes in October 2022, the preliminary results from the first 12 months of the trial have been very positive, the partners would like to move the project to the next stage to prove commercialisation.

The Victorian Government and GLaWAC are looking for on-country opportunities that show positive commercial potential for the Gunaikurnai one of the main aims of the trial is for GLaWAC to be in a position to make an informed business decisions at its conclusion on the best business development model and how to move the project to full commercialisation, this is most likely with an existing aquaculture business as a business partner.

SRO were chosen for this project as they are native and endemic in the Gippsland Lakes and have an established market and growing systems. Other species that were considered were Native flat oyster (Ostrea angasi) and the introduced species Pacific oyster (Crassostrea gigas) which are both present in the Gippsland Lakes only Native flat oyster (Ostrea angasi) have been approved for aquaculture production in Victoria. While Native flat oysters (Ostrea angasi) would be an option in the Gippsland Lakes the lack of proven markets and established growing systems was considered high risk, However, Pacific oyster (Crassostrea gigas) have not been approved for aquaculture in Victoria as they are not native and they are considered a invasive species which ruled them out as an option as they would not meet the bush food ethics and direction of Gunaikurnai people, the recognised native title holders of the Gippsland Lakes area.
With the success of the first year of the pilot trial, GLaWAC and the VFA have agreed to move the project to stage 2, which will establish semi-commercial scale plots to investigate the full commercial potential of SRO aquaculture in Eastern Victoria. This stage 2 trial will also provide employment, training and skills development for the Gunaikurnai people.

The trial will involve the establishment of approximately 1 hectare of oyster aquaculture infrastructure across seven replicated trial sites in the Gippsland Lakes (in the general area of the existing pilot trial) and will investigate and compare production in different oyster culture systems.

The project has involved extensive consultation with the seafood industry and aquaculture sector and the pilot project has been strongly supported by the Oyster industry and seafood industry. The pilot project also involved cross sector and community consultation with key stakeholders and the broader community.

Successfully developing a SRO aquaculture industry in eastern Victoria will benefit GLaWAC and the Gunaikurnai people, the broader seafood and aquaculture sectors, and local businesses including transport, tourism, hospitality and other support industries.
The project is of regional and national importance as it meets four of the priority areas of the National Fisheries Plan
• First Nations employment in the sector Key initiatives: 4.2, 7.1
• Sustainable development of the aquaculture sector Key initiatives: 2.6
• Employment, participation and health in the fishing, aquaculture, and seafood sectors Key initiatives: 7.1, 7.2, 7.3, 7.4
• Climate change and adaptation - shifting and shared stocks Key initiatives: 6.2, 6.3, 6.4

There is significant interest across Australia from first nations people to become involved in viable aquaculture ventures. This project aims to develop a new aquaculture industry using an established and marketable product in an area of Australia that is on the current margins of commercial SRO production.
Climate change is already increasing east coast water temperatures and extending the southern range of a number of species. These changes are likely to increase the potential for SRO aquaculture production in Eastern Victoria.

This project also aims to investigate the potential of a viable new first nations aquaculture industry on the Gippsland Lakes. The initial pilot project on which this application is based has shown that the growth and survival of SRO is commercially viable and as the Gippsland Lakes is a large waterway with no aquaculture industry, there is significant potential for a large commercial development based on SRO production in the area to support a regional aquaculture industry and local employment.

Objectives

1. Establish an Indigenous aquaculture industry with GLaWAC on the Gippsland Lakes
2. Improve skills, capacity and knowledge in the aquaculture and marine industries within the Gunaikurnai people
3. Investigate commercial viability of SRO in Eastern Victoria.
4. Develop processes and pathways for new aquaculture projects to Gain shellfish quality assurance.
5. Investigating the impact if any of oyster aquaculture on seagrass in southeast coast estuaries .
6. Investigate different oyster growing systems and subtility to Eastern Victoria
7. Developing a business plan for the commercialisation of the project

Cracking the code on captive breeding of Macquarie Perch

Project number: 2022-116
Project Status:
Current
Budget expenditure: $1,303,630.00
Principal Investigator: Taylor L. Hunt
Organisation: Victorian Fisheries Authority (VFA) Queenscliff
Project start/end date: 2 Apr 2023 - 1 Mar 2026

FRDC

Need

Currently, the inability to consistently produce Macquarie perch from captive held broodstock is severely constraining its recovery. Being able to captively breed Macquarie perch will firstly save the species from extinction from a conservation standpoint and secondly, re-establish recreational fisheries for Macquarie perch across its former range in Victoria, NSW and ACT. Establishing captive breeding may also provide new and unique opportunities for aquaculture in Australia for the commercial production of Macquarie perch, suitable for the restaurant industry, akin to Murray cod.

This proposal details four key focus areas of research and development to achieve captive breeding of Macquarie perch within three years, such that Government and in the future, private aquaculture hatcheries, can adopt commercial production of the species. The project seeks $698,630 of investment from FRDC and is supported with over $3 million of co-investment (including matching $605,000 cash and $2.41 million in-kind) from 9 partners across Victoria, NSW, Qld, and ACT. The project aligns with the FRDC R&D Plan 2020-2025, as well as priorities, actions and outcomes in other key national and state plans (Table 4).

Objectives

1. Develop and optimise artificial diets to meet the nutritional requirements of captive Macquarie perch broodstock and larvae.
2. Optimise the hormonal treatment and explore environmental manipulation to improve spawning of captive held Macquarie perch broodstock.
3. Review, refine and develop breeding strategies and husbandry practices in the hatchery to maximise fish production and fish stocking outcomes with learnings incorporated into Macquarie perch captive breeding hatchery manual.
4. Monitor and evaluate the success of stocked Macquarie perch fingerlings into rivers in northeast Victoria and, where research numbers permit, conduct genetic analyses to inform dietary treatment and genetic management of the species in ongoing captive breeding and stocking of the species.
5. Build community awareness and support by sharing information and encouraging participation in fish stocking and population monitoring events.

Utilisation of boat ramp cameras to estimate recreational fishing catch and effort in key Victorian fisheries

Project number: 2021-008
Project Status:
Current
Budget expenditure: $142,200.00

Need

There is no current information on total recreational fishing effort or landings for Victorian fisheries and therefore no continuous time series on these variables, as is the case in most jurisdictions. This represent a key knowledge gap, and hence risk, for fisheries sustainability in the state and has resulted in several fisheries (i.e. those with significant recreational catch) being assessed as ‘Undefined’ in the most recent SAFS round.
In addition to the above, the Victorian Government has brought out several bay and inlet fisheries over the last two decades, meaning recreational catch is the most significant harvest component for most species/stocks. This also means that there is no longer commercial logbook data being obtained on which to base assessment of these species/stocks. As such, having recreational catch and effort information will enable more sophisticated population dynamic stock assessment models to be used for assessment purposes. Victoria possesses such a model that is parameterised for the Western Victorian Snapper Stock (WVSS), complete with management strategy evaluation, that cannot be used to inform decision making at present because the landings from the largest fleet (i.e. boat based recreational fishers) are currently unknown.
Recreational catch and effort information will be used for ongoing stock assessment to inform management advice to inform the following immediate, direct priorities: 1) WVSS harvest strategy, 2) rebuilding of the Gippsland Lakes black bream stock, 3) Corner Inlet Management Plan, and 4) assessment of the eastern Victorian snapper stock.

Objectives

1. Calibration of boat ramp camera infrastructure
2. Extrapolation of fishing effort to boat ramps that do not have cameras using Google Earth imagery
3. Combining fishing effort information derived from boat ramp cameras and Google Earth with creel survey data to estimate the fishing effort and landings of snapper in Port Phillip Bay, the total boat based recreational landings in Corner Inlet and landings of black bream in the Gippsland Lakes

Giant Crab Enhanced Data Collection - Innovative approaches to enhance data collection in the Victorian, South Australian and Tasmanian Giant crab fisheries

Need

Giant Crabs are a long, lived, slow reproducing xanthoid crab distributed from southern Western Australia to central New South Wales that are considered to be a single stock across southern Australia.

The giant crab fishery (GCF) across southern Australia has a small tonnage of large, individually valuable animals. Despite the implementation of harvest strategies and management plans guiding the setting of conservative TACC’s, declining trends are evident across the shared Southern Australian resource.

The fishery has had ongoing problems collecting quality stock assessment data, leading to uncertainty in the assessment and management. Owing to the size of the fishery, and the remote nature of the fishing operations, assessments now rely on fisher dependant catch rate data with an inherent high level of volatility due to the small number of operators.

Attempts to improve the collection of fishery data over the years have been challenging, in particular for fisher-based collection of length-frequency data from volunteer measuring programs.

Innovative data collection methods for small scale fisheries such as the GCF are required to improve the monitoring of stock status of this important commercial fishery and enhance long-term sustainability of the Giant Crab resource.

A length based model has previously been developed and was designed to integrate assessments across the jurisdictions. The model for giant crab and was being used for South Australia and Tasmania but was not applied to Victoria due to data limitations. In recent years the modelling has discontinued in SA and Tas because of insufficient length frequency data, which compounded uncertainty present due to weak growth data. The lack of length data in previous years was the critical change that has forced the model to be discontinued.
So our ability to understand changes in the stock has become weakest at precisely the period in the history of the fishery when information is most needed. This project is designed specifically in response to this need to address the lack of data through development of an efficient method to collect LF information, with minimal burden on fishers to improve accuracy of stock assessments.

Objectives

1. Develop effective low-cost data collection method specific to Giant Crab
2. Trial and refine new data collection method
3. Analysis of fishery-independent biological data and investigation of usability to enhance assessment of Victorian, Tasmanian and South Australian giant crab fisheries
