Context: In a pioneering initiative in Maharashtra, Mumbai is preparing for the installation of 210 artificial reefs near Worli Koliwada.

  • The artificial reefs, composed of recycled cement and steel, will increase the sea surface area by 50-60 square feet per module.
  • They are expected to attract small and large native species, acting as a habitat and breeding ground.

An artificial reef is a human-made structure designed to replicate some characteristics of natural reefs. These structures include submerged shipwrecks, oil and gas platforms, bridges, and other offshore installations.

Materials used in their construction range from rocks and cinder blocks to limestone, steel, and concrete.

Artificial reefs enhance habitat for reef organisms like corals, fishes, and invertebrates.

They attract marine life, making them popular destinations for fishing, diving, and snorkelling, thus offering economic benefits to local communities.
