- Coral reef is a natural wealth owned by Indonesia. Target fish are types of consumption fish which associated with coral reefs. This study aimed to determine the extent of coral coverage to the abundance of target fish group in the territorial waters of Tangkil Island, Lampung Bay. The study was conducted in August 2016 at 2 station. Data were taken by using quadratic transects for coral reefs and transect belts with transect belt video methods for target fish. The types of coral reefs found in Tangkil Island, Lampung Bay were : Acropora Branching, Acropora Encrusting, Acropora Digitate, Acropora Submassive, Coral Branching, Coral Foliose, Coral Massive, Coral Mushrom.
