  abstract = {{D}espite actions to manage sustainably tropical {P}acific {O}cean reef fisheries, managers have faced failures and frustrations because of unpredicted mass mortality events triggered by climate variability. {T}he consequences of these events on the long-term population dynamics of living resources need to be better understood for better management decisions. {H}ere, we use a giant clam ({T}ridacna maxima) spatially explicit population model to compare the efficiency of several management strategies under various scenarios of natural mortality, including mass mortality due to climatic anomalies. {T}he model was parameterized by in situ estimations of growth and mortality and fishing effort, and was validated by historical and new in situ surveys of giant clam stocks in two {F}rench {P}olynesia lagoons. {P}rojections on the long run (100 years) suggested that the best management strategy was a decrease of fishing pressure through quota implementation, regardless of the mortality regime considered. {I}n contrast, increasing the minimum legal size of catch and closing areas to fishing were less efficient. {W}hen high mortality occurred due to climate variability, the efficiency of all management scenarios decreased markedly. {S}imulating {E}l {N}ifio {S}outhern {O}scillation event by adding temporal autocorrelation in natural mortality rates increased the natural variability of stocks, and also decreased the efficiency of management. {T}hese results highlight the difficulties that managers in small {P}acific islands can expect in the future in the face of global warming, climate anomalies and new mass mortalities.},
