Abstract:
Coral reef resources, particularly corals, macrobenthos and reef fish in Pujada Bay in
the southeastern coast of Mindanao were assessed in 2002 to determine their status.
A one-shot standard survey methods of corals and their associate fish was conducted
in the reef sites of Guang-guang, Manguihay, Lawigan, Mamali and Macambol. Softbottom macrobenthos in these reef sites were monitored for one year. Hard coral
cover in Pujada Bay was in a poor to fair category. Reef fish had low diversity and
indicator species were low in abundance - the conditions indicative of a degraded reef.
Reef fishes were dominated by low-valued species and high-value species had low
incidence - a profile symptomatic of overfishing. The preponderance of herbivore fish
species in some reef areas bespeaks of the important role of vegetation in supporting
the productivity of the reef. The reef sites supported a diverse group of macrobenthos
largely, mollusks. Reefs in Macambol showed a good coral-reef fish condition while
that in Mamali was in a poor state. Despite the latter, the reef supported a good number
of macrobenthos and reef fish. Protective, enhancement and rehabilitation activities
are needed to stop if not reverse the dismal situation of the Bay. Good management
of land-based activities must also be pursued alongside reef ecosystem management.
