Marine reserves deliver impressive increases in the abundance and size of exploited species on protected reefs, but larval dispersal makes it difficult to estimate their wider benefits. Australia's Great Barrier Reef (GBR) contains an extensive network of marine reserves. By combining GBR-wide fish surveys, larval dispersal models, and commercial fishery catch data, we calculate the system-wide ecological and economic contributions of these reserves for coral groupers ( spp.), the region's most important line fishery. Despite covering only 30% of reef habitat, the GBR's marine reserve network contains half of the species' biomass and generates most of its reproductive output (55%), half of the system's larval settlement (50%), and almost half of the total fishery yield (47%).
海洋保护区能显著增加受保护珊瑚礁上被开发利用物种的数量和体型，但幼体扩散使得评估其更广泛的效益变得困难。澳大利亚的大堡礁（GBR）拥有广泛的海洋保护区网络。通过整合全大堡礁范围的鱼类调查、幼体扩散模型和商业渔业捕捞数据，我们计算了这些保护区对珊瑚石斑鱼（珊瑚石斑鱼属物种）这一该地区最重要的延绳钓渔业的全系统生态和经济贡献。尽管海洋保护区网络仅覆盖了30%的珊瑚礁栖息地，但却包含了该物种一半的生物量，并产生了大部分的繁殖产出（55%）、系统内一半的幼体沉降量（50%）以及几乎一半的渔业总产量（47%）。
