Abstract

ABSTRACT Many fish schools are regarded as leaderless, where any individual can guide the direction of group motion at any given moment. We conditioned a fish school of black neon tetra (Hyphessobrycon herbertaxelrodi) to find food in aparticular location, while another group swam freely with no particular goal. Groups were composed of similar individuals in terms of body size, task knowledge and hunger level. Our hypothesis was that leadership would be less stable when fish were conditioned than when they were not. Although stability tended to be greater in the conditioned group, the hypothesis was not confirmed, as both groups showed asimilar degree of leadership stability. Leadership was not entirely random and some individuals took the lead more often than others. Leaders tended to be at the front of the school and their tendency to lead was loosely related to higher swimming speeds, and not related to task knowledge.

黑色霓虹灯四环乐学校的领导和集体行动:任务重要吗?

许多鱼群被认为是无领导的，任何个体都可以在任何给定的时刻引导群体运动的方向。我们训练了一群黑色霓虹鱼在特定的位置寻找食物，而另一组则自由地游泳，没有特定的目标。小组由体型、任务知识和饥饿程度相似的个体组成。我们的假设是，当鱼受到条件限制时，它们的领导力会比不受条件限制时更不稳定。尽管条件组的稳定性更强，但这一假设并未得到证实，因为两组的领导稳定性程度相似。领导并不完全是随机的，有些人比其他人更经常地担任领导。领导者往往站在学校的最前面，他们的领导倾向与更高的游泳速度有松散的关系，而与任务知识无关。

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
