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）密度的自然斑礁开展的观测性野外研究，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密度变化而发生改变。每个斑礁均于一日中的三个时段开展调查：黎明、正午与黄昏，且每次调查时均选取两条目标蓑鲉进行观测。所有蓑鲉在首次被观测到时的行为均被记录，此部分记为「初始行为（Initial behaviors）」。选取1~2条目标蓑鲉进行时长10分钟的连续观测，并记录其全部活动，此部分记为「焦点行为（Focal behaviors）」。每次调查期间，均记录每个斑礁上蓑鲉从周边海草生境迁入或迁出的数量，此部分记为「移动（Movement）」。每次调查结束后，均开展本地猎物鱼类种群的普查工作，此部分记为「本地鱼类调查（Native fish surveys）」。
