WestAus Carnarvon Oyster Trial

Closed 3 Jun 2018

Opened 28 May 2018


Harvest Road Export Pty Ltd is proposing to undertake a two year trial of rock oyster aquaculture at nine sites within the Wooramel Bank, situated along the eastern shoreline of Shark Bay, in the Gascoyne Region.  The Wooramel Bank forms part of the Shark Bay Marine Park and World Heritage area. 

The trial project comprises of nine small sites along a 40 kilometre length of the Wooramel Bank. Seven sites will have intertidal culture systems of oyster baskets held on longlines such that baskets are aerially exposed at low tide.  Longlines will be 25m in length and constructed as thee sets of triplicate lines with a 700m2 footprint. The intertidal sites would be in 1-2m of water approximately 1-2 kilometres offshore.  Two sites would be placed further seaward at 3-6m depth and have subtidal systems of a single 140m longline with baskets held on floats just below the water surface.

Rock oysters from the locally occurring milky oyster, Saccostrea scyphophilla and black lip oyster, Saccostrea cucullata species will be cultured.

The trial will include periodic visitation of the sites using a small boat during which oysters will be examined.  The trial will also include a series of environmental monitoring projects to investigate the potential for a full commercial project to cause environmental impacts.


Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
