Atlantic Croaker Group Shoaling Dynamics

This study examined the influence of oil exposure on group dynamics in Atlantic croaker. Wild caught live croaker were collected and placed into one of 3 treatment groups; control, mixed, or oil. Mixed and oil groups were conducted using a high and low oil dose. Groups were then placed in an arena and 10 minute recording of movements were taken and assessed for velocity, distance moved, distance to closest neighbor, and distance to the wall.

本研究探究了石油暴露对大西洋石首鱼（Atlantic croaker）种群动态的影响。研究人员采集野生活体大西洋石首鱼，将其分配至3个实验组：对照组、混合组与石油暴露组。其中混合组与石油暴露组分别设置高、低两种石油剂量。随后将各组鱼群置于行为观测池（arena）中，录制10分钟的运动影像，并针对运动速度、移动距离、与最近邻个体的间距以及与池壁的间距四项指标开展分析评估。相关影像数据可于GRIIDC数据集R4.x258.000:0047中获取。
