This paper reviews the effects of long-term protective management on fish abundances at coral-reef reserves and nonreserves and on fish yields at nonreserves at four small islands in the central Philippines. One of the studied reefs lost its protection after ten years, becoming a natural experiment on the effects of protection. Factors influencing fish yields and management problems affecting Philippine marine reserves are briefly discussed. Fish abundances were censused visually; data showed that fish abundances and standing stock of highly fished species were significantly higher in reserves than in nonreserves and control sites. Annual fish yields were estimated with daily records of fish catches from various types of gear, and with monthly samples of catches. The data revealed that protection at the ten-year site was responsible for maintaining high fish yields; it also revealed that the reserve exported biomass to the nonreserve (fishing) area. The effects of less than five years' protection at two other reefs were not evident, although some species increased in abundance. A fish-monitoring program at the protected reefs is intended to test the generality of the conclusions drawn from data on one reef.
