Most marine organisms produce tiny offspring that are dispersed unknown distances by oceanic currents. Our present strategies to manage marine resources lack this vital piece of information. This study will apply two revolutionary techniques that finally enable us to determine how far marine larvae travel. Using the team that developed these techniques, field studies will for the first time measure both retention of fish larvae within marine protected areas and dispersal of larvae to adjacent fished areas on coral reefs. This information can be directly applied to optimize the size of reserves and their spacing in marine protected area networks.

大多数海洋生物产生微小的后代，这些后代被洋流分散到未知的距离。我们目前管理海洋资源的战略缺乏这一重要信息。这项研究将采用两种革命性的技术，最终使我们能够确定海洋幼虫的旅行距离。利用开发这些技术的小组，实地研究将首次测量海洋保护区内鱼苗的保留情况和鱼苗向珊瑚礁上邻近捕鱼区的扩散情况。这一信息可直接用于优化海洋保护区网络中的保护区规模及其间距。
