DLNR manages the marine resources of this near shore urban area, and allows fishing during even-numbered years.

However, no fishing is allowed during odd-numbered years, so that fish and other aquatic species can rest and repopulate.

The Waikiki-Diamond Head shoreline fisheries management area encompasses the nearshore waters between the 'Ewa wall of the Waikiki War Memorial Natatorium and the Diamond Head Lighthouse, and from the high-water mark on shore to a minimum seaward distance of 500 yards, or to the edge of the reef if one occurs beyond 500 yards.

Adjacent to the fisheries management area is the Waikiki Marine Life Conservation District, located between the 'Ewa edge of the Natatorium and the 'Ewa edge of the Kapahulu groin (seawall).
