Members of several shoaling species have been shown to prefer to associate with familiar individuals, enhancing the benefits of aggregation. The authors used a series of social preference tasks in the laboratory to evaluate whether prior familiarity with potential partners influences preference of shoaling partner in male zebrafish (Danio rerio), a social species found in shallow, slow-moving waters. The authors found that though male zebrafish exhibited a strong preference for shoaling with a male conspecific as opposed to remaining alone, they exhibited no preference for familiar over unfamiliar conspecifics. This suggests that the benefits of familiarity for shoaling behaviour may not be as important for male zebrafish as has been shown in other social fish species.
研究表明，一些群居物种的成员更喜欢与熟悉的个体结伴，从而增强了群体聚集的好处。作者在实验室中使用了一系列社会偏好任务来评估潜在伴侣的熟悉度是否会影响雄性斑马鱼（Danio rerio）的群居伙伴偏好，雄性斑马鱼是一种生活在浅水区、水流缓慢的水域中的群居物种。作者发现，虽然雄性斑马鱼表现出强烈的偏好与同种雄性个体一起群居，而不是独自生活，但它们对熟悉的同种个体没有表现出偏好。这表明，熟悉度对雄性斑马鱼的群居行为的好处可能不如其他社交鱼类物种那么重要。
