海洋保护区被视为保护被开发物种和促进沿海渔业有效管理的旗舰工具。然而，海洋保护区在多大程度上是全球相互关联的，能够有效地在渔业对粮食和生计安全至关重要的地区播种，这在很大程度上是未知的。使用一个流体动力学模型的幼虫扩散，我们预测，大多数海洋保护区是不相互关联的电流和捕鱼区的潜在利益目前是有限的，因为国家高度依赖沿海渔业得到很少的幼虫供应海洋保护区。然而，这种全球性的不匹配是可以扭转的，办法是将新的海洋保护区放在足够偏远的地区，以尽量减少社会和经济成本，但通过洋流充分连接，以培育开发最多的渔业和濒危生态系统。
Marine reserves are viewed as flagship tools to protect exploited species and to contribute to the effective management of coastal fisheries. Yet, the extent to which marine reserves are globally interconnected and able to effectively seed areas, where fisheries are most critical for food and livelihood security is largely unknown. Using a hydrodynamic model of larval dispersal, we predict that most marine reserves are not interconnected by currents and that their potential benefits to fishing areas are presently limited, since countries with high dependency on coastal fisheries receive very little larval supply from marine reserves. This global mismatch could be reversed, however, by placing new marine reserves in areas sufficiently remote to minimize social and economic costs but sufficiently connected through sea currents to seed the most exploited fisheries and endangered ecosystems.
