Artificial reefs and fish aggregating devices

There are several artificial reefs located in the Northern Territory at Fenton Patches, Darwin Harbour, Dundee, Adelaide River Mouth, North Gutter and Lee Point.
Artificial reefs and fish aggregating devices (FADs) create new fish habitat and provide new fishing areas that can help reduce pressure on existing natural reefs and fish stocks.
Engineered artificial reefsFour specifically engineered reef complexes were installed in 2019.
The reef complexes are large concrete structures that are five metres tall and four metres square at the base, weighing about 24 tonnes.
The reefs are expected to last up to 100 years and will attract a variety of species to suit a range of fishing techniques and abilities.
