Effect of lionfish presence on native fish abundance on satellite coral heads in seagrass habitats on Eleuthera, Bahamas during 2013 (Biodiversity Loss Effects Lionfish project)

<p>This field experiment was conducted on coral patch reefs to test for the effect of lionfish presence on native fish abundance both on main reefs where lionfish resided and in habitats surrounding the main reefs (satellite coral heads, open areas, and standardized habitat units [SHUs]). The experiment used 16 main reefs which were manipulated so that 8 reefs had few lionfish present (low lionfish treatment) and 8 had lionfish present at naturally-observed densities (high lionfish treatment). Complete censuses of the native prey fish populations on each reef and in the surrounding habitats were conducted weekly for 7 weeks during the summer recruitment season.&nbsp;</p>

本野外控制实验以珊瑚斑礁为研究对象，旨在探究蓑鲉（lionfish）的存在对本土猎物鱼类丰度的影响，实验覆盖范围同时包含蓑鲉栖息的主礁区，以及主礁周边生境（包括卫星珊瑚礁、开阔区域与标准化生境单元[standardized habitat units, SHUs]）。本实验共设置16个主礁，通过人为调控实现两组处理：8个主礁仅维持低密度蓑鲉种群（低蓑鲉密度处理组），剩余8个主礁保持自然观测到的蓑鲉种群密度（高蓑鲉密度处理组）。在夏季鱼类补充季期间，研究人员连续7周、每周对每个主礁及其周边生境中的本土猎物鱼类种群开展全面普查。
