Focal lionfish behaviors at different densities of local lionfish and prey fish in Eleuthera, Bahamas from July to August in 2012

<p>This was an observational field study on natural patch reefs with varying lionfish densities to determine if lionfish behavior and movements change at different local lionfish and prey fish densities. &nbsp;Each reef was visited at three times of day: dawn, midday, and dusk, and two focal lionfish were observed during each visit at each reef. Behaviors of all lionfish were recorded the moment they were first sighted (\"Initial behaviors\").&nbsp;One or two focal lionfish were observed for 10 minute intervals and all activity was recorded (\"Focal behaviors\"). &nbsp;The number of lionfish on each reef that arrived at or departed from each reef to/from the surrounding seagrass habtiat was recorded throughout each visit (\"Movement\"). &nbsp;Censuses of the native prey fish populations were conducted at the end of every visit (\"Native fish surveys\").</p>

本研究为一项针对不同蓑鲉（lionfish）密度的自然斑块礁开展的野外观测研究，旨在探究蓑鲉的行为与移动模式是否会随当地蓑鲉及猎物鱼类的种群密度变化而发生改变。每处斑块礁均于一日内的三个时段开展采样探访：黎明、正午与黄昏，且每次探访期间均观测2尾目标蓑鲉。所有蓑鲉的行为将在首次被观测到的瞬间予以记录，该记录项命名为「初始行为」。以10分钟为采样间隔，观测1至2尾目标蓑鲉并记录其全部活动，该记录项命名为「焦点行为」。每次探访全程均记录每处礁体上进出周边海草栖息地的蓑鲉个体数量，该记录项命名为「移动情况」。每次探访结束后，均开展本地猎物鱼类种群的普查工作，该记录项命名为「本地鱼类调查」。
