Self-organizing motion is an important yet inadequately understood phenomena in the field of collective behavior. For birds flocks, insect swarms, and fish schools, group behavior can provide a mechanism for defense against predators, better foraging and mating capabilities and increased hydro/aerodynamic efficiency in long-distance migration events. Although collective motion has received much scientific attention, more work is required to model and understand the mechanisms responsible for school initiation and formation, and information transfer within these groups. Here we investigate schooling of black tetra ( Gymnocorymbus ternetzi ) fish triggered by startle stimuli in the form of approaching objects. High-speed video and tagging techniques were used to track the school and individual members. We then measured several variables including reaction times, group formation shapes, fish velocity, group density, and leadership within the group. These data reveal three thin...

Tetra 鱼的学校形成特征和基于刺激的建模。

自组织运动是集体行为领域中一个重要但未被充分理解的现象。对于鸟群、昆虫群和鱼群，群体行为可以提供一种防御捕食者的机制，更好的觅食和交配能力，并在长距离迁徙事件中提高水力/空气动力效率。尽管集体运动受到了很多科学关注，但需要做更多的工作来模拟和理解负责学校启动和形成的机制，以及这些群体内的信息传递。在这里，我们调查了由接近物体形式的惊吓刺激引发的黑色 tetra ( Gymnocorymbus ternetzi ) 鱼的聚集。高速视频和标记技术被用来跟踪学校和个人成员。然后我们测量了几个变量，包括反应时间、群体形成形状、鱼的速度、群体密度和群体内的领导力。这些数据揭示了三个薄...
