Indonesia’s coral reefs support over half of all small-scale fishers globally and are thus an important economic and sociocultural resource. These coral reef fisheries, however, are threatened from a variety of stressors including overexploitation. No-take fisheries closures are thought to be a suitable management strategy in Indonesia that provide a refuge for fish species with different ecological and life-history characteristics. While examining such indicators is increasingly important to determine management efficacy, few have done so in Indonesia. I investigate community ecological and life-history responses to no-take fisheries closures using abundance data from 2009-2015 in three regions across Indonesia’s Sunda Banda Seascape. Overall, fish biomass was 30% greater in no-take closures than fished reefs. The only functional groups to respond to management were corallivores and detritivores, and fished reefs had greater biomasses of these groups. No-take closures had fish communities with greater maximum lengths, longer life spans, slower growth rates, and higher mean trophic levels. Surprisingly, total fish biomass was not a good predictor for life history values or functional group biomass. These results indicate that non-target fish species may thrive in fished reefs where predators with slow life histories are reduced. Also, no-take closures in Indonesia’s Sunda Banda Seascape are facilitating recovery of life-history characteristics and fish biomass but these impacts are not uniformly distributed across functional groups. My findings are of value to current ecosystem-based management objectives attempting to achieve broader conservation goals of maintaining ecological sustainability.
