Dispersal of grouper larvae drives local resource sharing in a coral reef fishery.

摘要: Summary In many tropical nations, fisheries management requires a community-based approach because small customary marine tenure areas define the spatial scale of [1]. However, fate larvae originating from community's is unknown, and thus degree to which community can expect their actions replenish within unclear [2, 3]. Furthermore, whether how much larval dispersal links provide strong basis for cooperative [4, 5]. Using genetic parentage analysis, we measured single, managed spawning aggregation squaretail coral grouper ( Plectropomus areolatus ) determined its contribution replenishment five up 33 km at Manus Island, Papua New Guinea. Within area containing aggregation, 17%–25% juveniles were produced by aggregation. four adjacent areas, 6%–17% Larval kernels predict that 50% settled 14 km These results strongly suggest both local benefits communities over scales.
