We investigated pairwise association patterns and shoal fidelity in free-ranging, individual three-spine sticklebacks (Gasterosteus aculeatus) by capturing entire shoals of sticklebacks and tagging each shoal member with a unique individual mark before releasing the shoal at the point of capture. We recaptured tagged fishes in the study area on five subsequent days, noting their identity, their location and the individuals with which they were associated. Stable partner associations between fishes were observed which might provide the basis for shoal fidelity via social networks. These results suggest the potential for the kinds of inter-individual association patterns assumed by models of predator inspection and 'tit-for-tat' behaviours in free-ranging fishes.
我们通过捕获整群三刺鱼，并在捕获点将每群三刺鱼的成员标记上独特的个体标记后再放生，研究了自由活动的个体三刺鱼（Gasterosteus aculeatus）之间的两两关联模式和鱼群忠诚度。在随后的五天里，我们在研究区域重新捕获了带标记的鱼，记录它们的身份、位置以及与之关联的个体。观察到鱼之间存在稳定的伙伴关联，这可能为通过社交网络实现鱼群忠诚度提供基础。这些结果表明，在自由活动的鱼类中，存在着捕食者检查模型和“以牙还牙”行为所假设的个体间关联模式的可能性。
