摘　　要：为探究斑马鱼(Danio rerio)对有无繁殖经历的成年异性同类是否具有视觉偏好,在斑马鱼繁殖期,将有、无繁殖经历的成年异性斑马鱼作为刺激鱼分别置于装有雄性(或雌性)受试鱼鱼缸的两侧鱼缸内,拍摄受试鱼偏好行为视频10 min后,对它们的有关偏好行为测试参数进行分析。结果显示:1)与雌性受试鱼相比,雄性受试鱼撞击有繁殖经历偏好区缸壁的时间和频次、撞击两侧偏好区缸壁的总时间和总频次、靠近各偏好区的频次及靠近两侧偏好区的总频次均有明显的增加;2)雄性斑马鱼撞击有繁殖经历偏好区缸壁的时间、频次明显多于撞击无繁殖经历偏好区缸壁的时间、频次,它们靠近有繁殖经历偏好区的时间也明显多于靠近无繁殖经历偏好区的时间。上述结果提示雄性斑马鱼在繁殖过程中占据主导地位,且对有繁殖经历的雌性斑马鱼有更强的视觉偏好;雌性斑马鱼在繁殖过程中处于从属地位,对配偶的选择与对方是否有繁殖经历无明显的偏好性。To investigate whether zebrafish(Danio rerio)have a visual preference for adult heterosexual conspecifics with or without breeding experience,adult heterosexual zebrafish with and without breeding experience were placed as stimulus fish on both sides of the tank containing male(or female)subject fish during the zebrafish breeding season,and after taking videos of the subjects’preference behaviors for 10 min,their parameters related to the preference behavior test were analyzed.The results showed that:1)The duration and frequency of hitting the wall of the preference zone with breeding experience,the total duration and frequency of hitting the wall of both preference zones,the frequency of closing to each preference zone,and the total frequency of closing to each preference zone,were all significantly higher in male zebrafish than in female test fish.2)The duration and frequency of hitting the wall of the preference zone with breeding experience was significantly more than that of hitting the wall of the preference zone with no breeding experience,the duration of male zebrafish closing the breeding experience preference area was significantly more than that of closing the non-breeding experience preference area.These results suggest that male zebrafish dominate the breeding process and have a stronger visual preference for female zebrafish with breeding experience,while female zebrafish are in a subordinate position during the breeding process and do not have a clear preference for mates with or without breeding experience.
