The seaside is covered by various types of coast type to maximize the diversity of ecosystem. The lagoon side is covered by rich topsoil covered of various plants and cultivation.

The bottom of the lagoon is open to the deep sea, but protected from unwanted predator by a net. Many forms of mariculture are practiced in box and other systems hanging at different depth. The low sea state of the lagoon may shelter floating photobioreactors producing algae as the base of the mariculture food chain.
