The coral communities of Mararison Island, Culasi, Antique, Philippines
2006
An assessment of the extensive fringing reefs surrounding Mararison lsland, Culasi, Antique was undertaken in 1994 to 1996 and in 1998 to provide scientific basis for management and enhancement of the island s resources as part of the Community Fisheries Resource Management project launched in 1991. The fringing reefs on the northwest side of the island are characterized by high percent coral cover (53-65%) consisting of very diverse coral species. The dominant forms are branching non-Acropora,with numerous small colonies of other coral forms. In contrast, the southeast side of the island fronting the fishing village is depau perate (4.7 -17.6% coral cover) with few small colonies of encrusting and massive corals characteristic of stressed reefs. However, highest coral cover consisting of dense stands of branching Acropora interspersed with branching non-Acropora was observed along the reef slope of Nablag station located at the western end of the island. Coral cover in the offshore reef (Guiob) was relatively fair (24%-46%). A total of 166 scleractinian corals were seen although only few species occurred frequently or provided high percent coral cover. Following the bleaching event of 1998, dramatic decreases (30%-61%) in live coral cover, particularly along the reef slopes, were observed in all stations.
