Marine‐protected areas (MPAs) are an effective means of improving habitat quality and biodiversity in the world’s oceans. While the advantages of MPAs as a mechanism for conservation and biodiversity are well established, the potential improvements to fishery performance resulting from a network of MPAs are still being established. Countries around the world have committed to establishing networks of MPAs within their waters by 2020, in response to the United Nations Convention on Biological Diversity. This, coupled with the increasing global demand for seafood and heavy reliance on fishery resources as a source of economic development for many coastal communities, means that an understanding of how these networks can be expected to impact fishery performance is extremely important. We use a difference‐in‐difference modelling approach to isolate the change in the fishery performance associated with the south‐east marine reserve network in Australia. We find no evidence that the economic performance of adjacent fisheries was negatively impacted by the network. This lack of impact is likely due to a network design explicitly intended to avoid effort displacement in key fisheries, along with fishery management changes intended to remove excess fishing capacity.

海洋保护区网络如何影响邻近的渔业？来自澳大利亚的证据

海洋保护区（MPA）是改善世界海洋中栖息地质量和生物多样性的有效手段。尽管海洋保护区作为保护和生物多样性机制的优势已得到充分确立，但海洋保护区网络对渔业绩效的潜在改善作用仍在建立之中。为响应《联合国生物多样性公约》，世界各国承诺到2020年在其水域内建立海洋保护区网络。这加上全球对海鲜的需求不断增长以及对许多沿海社区经济发展的依赖-渔业资源的严重依赖，这意味着对这些网络如何影响渔业绩效的理解至关重要。我们使用差异建模方法来隔离与澳大利亚东南海洋保护区网络相关的渔业绩效变化。我们找不到证据表明该网络对邻近渔业的经济表现产生负面影响。这种影响的缺乏可能是由于网络设计明确旨在避免关键渔业的工作量转移，以及旨在消除过度捕捞能力的渔业管理变更。
