Artificial reefs and fish aggregating devices

An artificial reef is a man-made underwater structure built to promote marine life.

It is used to create new habitat for fish to help increase numbers and reduce pressure on existing natural reef and fish stocks.

There are several artificial reefs located in the Northern Territory at Fenton Patches, Darwin Harbour and Lee Point.

Artificial reefs and fish aggregating devices (FADs) improve fishing opportunities. They also help protect at-risk reef fish species such as golden snapper and black jewfish.

FADs like buoys or floats are used on or below the ocean's surface and anchored to the bottom.

They attract species more suited to catch and release such as tuna, trevally, queenfish, mackerel and billfish.
