What is being decided?

Three locations have been short-listed for a new artificial reef off the SA Coastline that will enhance recreational fishing opportunities in the state. Artificial reefs are popular with recreational fishers and have been used globally to restore lost habitats. This restoration works hand-in-hand with fisheries management and marine parks, ensuring our ocean is healthy, well managed and offers great fishing opportunities for the future.

The SA New Trial Artificial Reef Project Options Paper (PDF, 3MB) sets out the three proposed locations and designs for South Australia’s first trial artificial reef project for recreational fishers in SA

The project is part of the State Government’s $3.25 million support package to boost recreational fishing and tourism opportunities in areas possibly affected by marine parks. For more background information about the project, click here (PDF, 2.4MB).

The three proposed locations are:

Option A
Southern Metropolitan Adelaide
A number of options near Encounter Marine Park including Hallett Cove, O’Sullivans Beach, Seaford and Moana.

Option B
North Western Gulf St. Vincent
Between Ardrossan and Stansbury

Option C
North Eastern Gulf St. Vincent
West to southwest of Port Wakefield

More detailed information about the Reef Design can be found in the Background tab.

To choose your preferred location and give your feedback, please fill out the feedback form and join the online discussion.

Community meeting opportunities

Everyone is welcome to attend our public meetings to hear about the proposed locations, reef designs and further information about the project.

Ardrossan Town Hall
Corner of First and Fourth Streets, Ardrossan
Tuesday 8 December, 7.00pm - 8.30pm

Port Noarlunga Surf Life Saving Club
Saltfleet Street & Esplanade, Port Noarlunga
Wednesday 9 December, 7.00pm - 8.30pm

How can your input influence the decision?

We want you to tell us which option you'd like to see happen - your feedback and input will help shape the Government's decision on the final location of the first trial artificial reef in South Australia. To choose your preferred location, you can fill in the feedback form and you can also join the online conversation.

All submissions will be considered and a decision on the final location will be decided in early 2016.

Background


Tell us you preferred location here.

Download the SA New Trial Artificial Reef Project Options Paper (PDF, 3MB) and Background Paper (PDF, 2.5MB).

The State Government supports a best practice approach to the artificial restoration and implementation of reefs that enhance fish habitat.

Reef Design

A three-dimensional segmented reef structure will be built using a combination of high and low profile substrate, laid in rows creating a ridge formation, much like an agricultural field when sown. Substrate types will be loosely and tightly aggregated to create complexity, reflecting a ‘broken bottom habitat’. This substrate will be interspersed with a low profile structure, ‘seeded’ (attached) with spat and adult native shellfish species will be attached.

Substrate could include a combination of:

  • 'Reef balls’ or purpose built concrete
  • Large and small limestone rubble
  • Shell (oyster, scallop or razorfish shell)

Location Options

Option A
Southern Metropolitan Adelaide
A number of options near Encounter Marine Park including Hallett Cove, O’Sullivans Beach, Seaford and Moana

Option B
North Western Gulf St. Vincent
Between Ardrossan and Stansbury

Option C
North Eastern Gulf St. Vincent
West to southwest of Port Wakefield

All options will involve the reef being located in approximately 5m to 10m depth of water.

These locations were informed by consultation in May 2015 and are based on the recommendations of the recreational fishing and broader community.

STAGES OF REEF DEVELOPMENT OVER TIME

Figure above: 1. A range of substrates, some ‘seeded’ with juvenile native oysters, known as spat, will be deployed. 2. Spat grows and develops into larger oysters, with the reef beginning to attract a range of marine species associated with large numbers of shellfish. 3. Grown oysters then spawn, increasing the shellfish population on the reef. 4. The diversity and number of species associated with the reef grows, building a diverse, productive and healthy marine habitat for the future.

    What has been decided?

    The Yorke Peninsula, northwestern Gulf St Vincent, has been chosen as the location of South Australia’s new artificial reef trial.

    The $600,000 pilot project is the first artificial reef trial of its kind in South Australia and will contribute to a healthier, enhanced marine environment, improved recreational fishing, tourism and employment opportunities. This project forms part of the State Government’s $3.25 million commitment to boost recreational fishing and tourism opportunities.

    The South Australian Government has conducted two rounds of consultation regarding this development, whereby the hundreds of members of the public have attended, shown support for the project, and contributed to the location of the development.

    The northwestern Gulf St Vincent was chosen as being the most viable option due to it being a popular area for recreational fishers and for its suitability to establish a mixed substrate shellfish reef and diverse range of species.

    In collaboration with DEWNR, RecFish SA and other government agencies, PIRSA will install an artificial oyster reef on the seabed of the northwestern Gulf St Vincent through the South Australian Recreational Fishing Habitat Enhancement Project.

    A public tender process for the artificial reef construction and deployment will commence shortly. The reef construction is planned to be completed in 2016.

    The design of the reef focuses on enhancing marine habitat, specifically incorporating restoration of native oyster reefs, which have been lost from extensive areas of the state’s coastline.

    The artificial reef will be built using purpose-built reef structures, such as reef balls, substrates of limestone and shell and live native flat oysters.

    The exact site of the reef in the waters of the northwestern Gulf St Vincent – between Ardrossan and Stansbury – will be informed by detailed engineering design, bio-physical data, marine users in the area and logistical and cost considerations. Once the reef is completed and open to the public, the site GPS coordinates will be released.
