Fishers use towed dredges. The dredge used in the fishery is constructed of a heavy steel frame covered with steel mesh but open on the front side which is towed and is used to lift scallops out of the sand and mud.
Read more about towed dredges.
This fishery operates in the Bass Strait above Tasmania and extends from the Victoria/New South Wales border, around southern Australia to the Victoria/South Australia border. The fishery is between the Victorian and Tasmanian scallop fisheries that lie within 20 nm of their respective coasts.
Major landing ports
- Apollo Bay (Victoria)
- Queenscliff (Victoria)
- Stanley (Tasmania)
- Devonport (Tasmania)
- Fresh product – Domestic
In previous years some product has been exported, however, regular export markets do not currently exist.
Commercial fishers are able to target doughboy scallop, a species common throughout Bass Strait that is rarely retained as markets for the species do not currently exist.
The default period for the season is 1 April to 31 December.
Management of catch
Management of the Bass Strait Central Zone Scallop Fishery involves both input (effort) and output (catch) controls. These include seasonal and spatial closures and catch limits for both species of scallops.
The total allowable catch limit is distributed as quota allocations between concession holders in the fishery and these quota allocations can be transferred temporarily during the season or permanently to other concession holders.
There is high variability in abundance, growth, mortality, meat yield and condition of commercial scallops in the fishery. This variability means that management of commercial scallops has to be adaptable to sometimes rapidly changing circumstances. The stock recruitment relationship is sporadic and intermittent. Growth rates are variable within the fishery, with scallops growing at different rates in different areas.
The fishery is also managed through the Bass Strait Central Zone Fishery Harvest Strategy which contains rules that control the intensity of fishing activity. Under the harvest strategy, an initial total allowable catch of 150 tonnes is set at the start of the season and boats are permitted to fish throughout the fishery. In order to increase the catch limit above 150 tonnes, a scallop bed/s (no more than 2) containing a biomass estimate of at least 1500 tonnes needs to be identified and then confirmed by an independent survey. The identified bed/s is closed to fishing for the season and fishing is permitted throughout the remaining area of the fishery.
The total allowable catch limit is increased to:
- 1500 tonnes if the biomass estimate of the closed scallop bed is at least 1500 tonnes
- 3000 tonnes if the biomass estimate of the closed scallop bed is at least 3000 tonnes.
Licence to fish
Fishers need to hold statutory fishing rights allocated by AFMA to fish in the Bass Strait Central Zone Scallop Fishery.
Each season a statutory fishing right will hold a different kilogram value depending on the total allowable catch set in the fishery. Each operator is limited to catching the amount of quota in kilograms determined by the number of statutory fishing rights.
Statutory fishing rights allow fishers to catch the fish species that are under a quota. Statutory fishing rights are transferable between fishers.
In this fishery there are currently:
- 444 500 commercial scallop quota statutory fishing rights
- 455 000 doughboy scallop quota statutory fishing rights
Number of active boats
- 11 active boats
Data about the catch and effort of the fishery is collected from the logbooks fishers fill out for every fishing shot.
- the species and amount caught
- catch that is discarded
- the catch/release of any protected species and their life status
- set and haul times of each shot
- the location of each shot
- the type and amount of gear used
- interaction with wildlife and protected species.

Species risk assessments
AFMA regularly monitor the effects fishing activities have on marine species, habitats and communities through ecological risk assessments. The assessment results help to prioritise the management, research, data collection and monitoring needs for the fishery.
After the risk assessment is complete, an ecological risk management strategy is developed to address how AFMA will manage marine species, habitats and communities identified in the assessment as greatly impacted by commercial fishing operations.
Bycatch work plans
Bycatch in the Bass Strait Central Zone Scallop Fishery has been low primarily because of the targeted nature of fishing.
The Bass Strait Central Zone Scallop Fishery Bycatch and Discarding Workplan outlines ways to minimise the bycatch of species that are at a high risk of being caught as bycatch in the fishery. The plan focuses on discards or damaging interactions with fishing gear of juvenile or damaged commercial scallops, doughboy scallops, threatened, endangered and protected species and other non-targeted fish species.
A harvest strategy is used to help determine what the quota should be for the target species of the fishery. Fishing, environmental and economic information is included in the harvest strategy, which helps to monitor and maintain the sustainability of the targeted species.
All harvest strategies are developed in line with the Commonwealth Fisheries Harvest Strategy Policy and Guidelines.
To export from an Australian commercial fishery, the fishery must be accredited by The Department of the Environment, through the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
Conditions and recommendations that must be adhered to through the most recent accreditation can be found on the Department of the Environment website.
Commonwealth marine reserves are areas established under Australian environment law to help us conserve the spectacular marine life in our oceans. They allow ecologically sustainable use of our marine resources and provide special places for people to enjoy and appreciate the fantastic diversity of our marine habitats.
Marine reserves are sometimes known as marine protected areas or marine parks and are managed by the Department of the Environment.
More information about marine reserves can be found on the Department of the Environment website.
Fishing in the fishery
Fishing operators wanting to fish in the fishery must hold quota statutory fishing rights for all target species in the fishery.

The Bass Strait Central Zone Scallop Fishery Management Plan 2002 came into effect on 28 May 2014.
The objectives of the Bass Strait Central Zone Scallop Fishery Harvest Strategy are to keep stocks within the fishery at ecologically sustainable levels and, within that context, maximise the economic returns to the Australian community, and to pursue efficient and cost-effective management.
We recognise that fisheries management involves a broad range of stakeholders.
Here are just a few ways we are working with our stakeholders, who include industry, scientists, environmental groups and the community for an informed approach to fisheries management.
Each fishing season, AFMA officers discuss current trends in fishing and catches with industry members on advisory groups and with operators in port. All this information is useful for the continuing management of the fishery.
Scallop Management Advisory Committee
The Scallop Management Advisory Committee is the advisory body for the Bass Strait Central Zone Scallop Fishery. The committee includes representatives from AFMA, scientific agencies, environmental non-government organisations and state government.
See the Scallop Management Advisory Committee webpage for a summary of the latest discussions and outcomes from the committee.
Scallop Resource Assessment Group
The Scallop Resource Assessment Group provides research and scientific advice for the Bass Strait Central Zone Scallop Fishery. The group is composed of fishery scientists, fishery industry members, an economist, an AFMA representative, and an environmental non-government organisation representative.
See the Scallop Resource Assessment Group webpage for a summary of the latest discussions and outcomes from the group.
AFMA works closely with other government departments, such as the Department of Agriculture and Water Resources and the Department of the Environment. They help in providing advice and guidance on both domestic and international fisheries issues.
The fishery lies between the Victorian and Tasmanian scallop fisheries within 20nm of their respective coasts.
Representatives from the state fisheries agencies attend the Scallop Management Advisory Committee and Scallop Resource Assessment Group meetings and provide input and advice.
Environmental non-government organisations
Representatives from environmental non-government organisations are engaged through several forums to provide advice on research and management issues in the Bass Strait Central Zone Scallop Fishery.
- AFMA holds 2 to 3 environmental forums annually.
- There are representatives on the Scallop Management Advisory Committee and Scallop Resource Assessment Group.

AFMA uses many methods to monitor the compliance of fishing activities and collect data on fish stocks. These include:
One of the main monitoring methods used by AFMA is onboard scientific observers. Observers are people employed by AFMA to go out on boats and independently record catch, effort and biological information of each fishing trip.
They take samples from fish, such as the otoliths or ear bones, and these are used later to determine the age of the fish caught.
Observers also record the length, weight and sex of a sample of the fish caught during a trip and report on the other wildlife that may be seen, the weather conditions, the composition of commercial catch fate of species that are caught as bycatch.
Boats in the fishery must carry an AFMA observer when requested by AFMA.

A satellite monitoring system called a Vessel Monitoring System, or VMS for short, is fitted on all concession holders boats. This system helps AFMA to monitor vessel position, course and speed. The system regularly transmits the information to a database at AFMA.

Cameras on fishing boats – electronic monitoring
AFMA has electronic monitoring systems on some fishing boats. These systems have sensors linked to surveillance cameras that record fishing activity. These recordings can then be collected and monitored by AFMA. Electronic monitoring gives fishers a cost effective way to support monitoring and data collection.
