The movement of biological swarms is widespread in nature, and collective behavior enhances a swarm's adaptability to its environment. However, most research focuses on free swarm movement, overlooking the impact of environmental constraints such as tubes. This study examines the swimming behavior of Petitella georgiae through a tube. Observations of position, speed, and direction reveal that each fish is influenced by the swarm's distribution in its field of view. The speed ratio between the middle region and edge region positively correlates with tube angles, and higher speeds are associated with higher densities within specific angle ranges.
生物群体的运动在自然界中广泛存在，集体行为增强了群体对环境的适应性。然而，大多数研究集中在自由群体运动上，忽视了诸如管道等环境限制的影响。本研究通过管道考察了乔治小杆菌的游动行为。对位置、速度和方向的观察表明，每条鱼都受到其视野中群体分布的影响。中间区域和边缘区域的速度比与管道角度呈正相关，在特定角度范围内，较高的速度与较高的密度相关。
