How to Build Artificial Reefs

Communities are becoming interested in creating artificial reefs to replace natural reefs damaged by pollution, collision and other human activities. Fish stock numbers fall where natural reefs can no longer provide the hiding places where they live and breed.

Artificial reefs offer replacement structures for the fish. Experienced fishermen, who know the reefs and where the fish were once found, can help to locate new artificial reefs that will replace habitats and replenish fish populations.

Things You'll Need

Reef material
Boat or barge
Crane
Marine buoys

Instructions

- 1
  Find the right location where current reefs exist and damaged reefs that previously supported fish populations have been located. Damaged natural reefs can be extended using man-made materials, allowing more fish to reside in the reef area.
- 2
  Select materials that mimic natural underwater substances. Rock, concrete, unpainted iron and certain kinds of wood will last a long time in an undersea environment, with the least amount of chemical degradation, according to EcoAndEthic.Greenpress.com. Use materials that provide many small nooks and crannies for fish to hide.
- 3
  Map the correct configuration for the reef. Cluster the materials to allow for more colonization of marine life. Widely separated pieces will not invite large numbers of fish to congregate. Place line structures across the current as a sheltered environment for small fish.
- 4
  Deposit the reef correctly. Place marker buoys on the water before attempting to place the reef, then follow these markers to lower reef material into the water. Make sure the material settles in a stable position on the ocean floor.
- 5
  Monitor the progress of marine life at the location. Hire divers to periodically monitor the reef's position and the progress of habitation by marine life
