Artificial Reefs:
300 artificial reef modules were deployed in various shapes off the coast of Rameshwaram, Tamil Nadu, to enhance marine fisheries resources and coastal biodiversity.
- These reefs, located 3 nautical miles offshore at a depth of 6 meters, benefit fishermen from eight fishing villages.
- Artificial reefs are human-made structures placed on the seabed using biorock technology.
- This technology involves passing a low electrical current through water via electrodes near a steel structure, attracting dissolved minerals to form a calcium carbonate layer akin to natural coral reefs.
- These reefs provide hard surfaces for algae, barnacles, corals, and oysters to attach to, creating habitats for fish, absorbing carbon dioxide, and benefiting local fishing communities.
