Effect of lionfish presence on native fish abundance in main reefs where lionfish resided 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>

本野外实验以斑块珊瑚礁为研究对象，旨在评估蓑鲉（lionfish）的存在对本土鱼类丰度的影响，实验覆盖两类区域：一是蓑鲉栖息的主礁区，二是主礁周边的各类生境，包括卫星状珊瑚礁块、开阔区域与标准化生境单元（standardized habitat units, SHUs）。本实验共设置16处主礁并开展人为调控：其中8处主礁维持低蓑鲉种群密度（低蓑鲉处理组），剩余8处维持野外自然观测到的蓑鲉种群密度（高蓑鲉处理组）。在夏季鱼类招募季，研究人员连续7周每周对每处主礁及其周边生境中的本土猎物鱼类种群开展全面普查。
