As an effort to restore reef, artificial reefs were deployed at several areas especially within marine protected areas. Various types of artificial reef being used such as concrete unit, wooden boat, wabcore block and reef ball. These structure were said to be able to mimic the natural reef. The question is, does this man-made structure truly serve its purpose as habitat?
In my opinion, preliminary studies on the effectiveness of artificial reef should be done before any deployment being made. We cant simply dump anything and then hoping it will become new home for marine organisms.
