Shellfish reef coming to Glenelg

Thursday 28 May 2020

A native shellfish reef will be built off the coast of Glenelg North, making it the first reef of its kind in metropolitan Adelaide.

The $1.2 million project, which was initiated by The Nature Conservancy and supported by the State Government, will be seeded with baby oysters and construction is set to begin in September this year.

Holdfast Bay council is contributing $20,000 towards the project which will cover an area the size of Adelaide Oval.

“This is a huge win for our environment and marine tourism,” Holdfast Bay Mayor Amanda Wilson said.

“The reef will attract fish and provide a wonderful dive spot close to the city.

“It will also help with water clarity with the treatment works at Glenelg North and help produce more fish stock for fishing on the jetty. We hope it will also provide a measure of protection for sand at Glenelg North.

“A big thanks to the continually hardworking Environment minister David Speirs and The Nature Conservancy for their investment.”

The Glenelg North reef will be the second native shellfish reef for South Australia, after Windara Reef was built off the coast of Ardrossan, on the Yorke Peninsula in 2018.

The benefits of native shellfish reefs to the natural environment include:

  • Improved local fish populations
  • Improved water clarity due to the filtration power of oysters
  • Shoreline protection
  • Extra feeding habitat for migratory shorebirds
