UPV Journal of Natural Sciences, 2006 - University of the Philippines in the VisayasAn 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.
Community-based coral farming for reef rehabilitation, biodiversity conservation and as a livelihood option for fisherfolk T Heeger, FB Sotto, JL Gatus & C Laron - In LMB Garcia (Ed.), Responsible Aquaculture Development in Southeast Asia. Proceedings of the Seminar-Workshop on Aquaculture Development … Southeast Asia organized by the SEAFDEC Aquaculture Department, 12-14 October 1999, Iloilo City, Philippines, 2001 - SEAFDEC Aquaculture DepartmentThe present condition of marine resources in the Philippines is critical and a majority of coastal communities live below the poverty line. If it continues, the progressive degradation of coral reefs and overexploitation poses a dangerous trend. Coastal resource management strategies are facing a new challenge: the integration of social, economic and natural sciences in future concepts to reverse the current status of ecosystem destruction and improvement of the people s living conditions. Hence, the primary objective of the coral farm is to provide alternative livelihood to fisher families from their resources on a sustained basis. The second objective is the rehabilitation of degraded reefs. Currently coral colonies of 64 species are taken through fragmentation from the wild. After 6-12 weeks (depending on the species) of grow-out in the farm, the fragments were deployed at the rehabilitation site at an average of 2 fragments per square meter (=12.5% cover). The survival of fragments is high at 84%, despite the fact that some coral colonies were placed in unsuitable substrates by the fisherfolk. More trainings have to be conducted improve their knowledge of coral biology and community structure. The net cost of rehabilitating a one-hectare reef is U$2,100 for 12.5% cover. Additional profit from coral marketing is used for community projects identified by the folk. In this case, coral farming may be an option for livelihood and a cost-effective tool for reef rehabilitation.
Small-scale fisheries of coral reefs and the need for community-based resource management in Malalison Island, Philippines Fish landings in Malalison Island in the west central Philippines were monitored from February 1991 to January 1992 to determine the types of fishing gear employed, the predominant species caught, the catch per unit effort (CPUE), and the yield from the coral reefs. Fishing was monitored only during the spring tide periods, after a preliminary sampling showed no significant differences among four lunar phases. A total of 494 fishing operations was recorded. CPUE (kg per fisher h−1) by gear was 1.1 for spear guns, 1.4 for spear guns with compressor, 0.4 for set gill nets, 2.4 for drive-in gill nets, 1.2 for drift gill nets, and 0.7 for hook-and-lines. The CPUEs of Malalison gears are similar to those of other coral reef fisheries. Dominant species caught were fusiliers and surgeonfishes by gill net. surgeonfishes by spear gun, and snappers and groupers by hook-and-line. The fish yield from the Malalison coral reefs was estimated to be 5.8 t km−2 year−1, which is low, and similar to overexploited. reefs in the Philippines and elsewhere. Live coral cover averages 35% in Malalison. Reef degradation, high fishing effort, low yields, and the poverty of the fishing community suggest ‘Malthusian over-fishing’. Community based management and resource enhancement are being initiated by the SEAF-DEC Aquaculture Department to protect and sustain the fishery and improve the economy in Malalison Island.
