Marine Fish Culture

Marine fish culture involves rearing of marine fish from fry or fingerlings to marketable size in cages suspended by floating rafts usually in sheltered coastal areas.

The species cultured changed gradually over the recent years depending on the availability of imported fry. Common species under culture include green grouper, brown-spotted grouper, giant grouper, Russell's snapper, mangrove snapper, goldlined seabream, star snapper and red drum.

Fry are mostly imported from the Mainland, Taiwan, Thailand, Philippines or Indonesia. Traditionally, marine cultured fish are fed with trash fish. In recent years, increasing number of marine fish farmers have changed over to use moist or dry pellet feed which significantly reduces pollution caused by fish feed and improves both the feed efficiency as well as fish health.
