Abstract

An artificial reef is a man-made, underwater structure, generally built for the cause of promoting marine life in areas of the generally featureless bottom surface. Many reefs are built by the deploying existing materials to create a reef. An artificial reef is a human made structure base that is built up of specific aim of promoting the marine life of an area.

Some artificial reefs were generally built such as reef balls made from concrete or polyvinyl chloride (PVC) whilst others are manmade coral reef items that have been sunk on purpose such as wrecks or construction debris matter. Regardless of how they are built artificial reefs generally provide hard surfaces where invertebrates such as oysters and barnacles as well as corals attach. The accumulation of these things can be easily making artificial reefs popular with other species of fish who will visit the areas to feed.
