Q. Recently, Odisha's first artificial reef is deployed in which lake to restore aquatic ecosystems?
Answer:
Chilika lake
Notes: Odisha launched its first artificial reef in Chilika to restore aquatic ecosystems. Artificial reefs are submerged structures that create habitats for reef-dwelling organisms, such as fish, prawns, and crabs. While they don’t fully replicate natural coral reefs' functions like nitrogen fixation or carbon cycle regulation, they provide important shelter and reproduction space. These reefs help break strong sea waves, promoting the growth of seaweed, seagrasses, and marine plants, which serve as food for other organisms. Some artificial reefs use pre-existing objects like shipwrecks, as seen in Redbird Reef, Delaware.
