Some highly productive reef fisheries in the southern Philippines 24 yield sustainable harvests of 30 metric tons per square kilometer per year and produce up to 70 percent of the total fish catch in a given area. Small-scale fishermen in such areas can harvest up to 5,000 kg of fish a year (White, Hale, Renard, and Cortesi 1994).
