许多珊瑚礁鱼类表现出定期的本地化之间的觅食和产卵区的迁移，但影响这些迁移模式的因素，如距离，频率和产卵场的保真度知之甚少。本研究的目的是调查的模式迁移到产卵场的外科手术，Ctenochaetus striatus（Acanthuridae）。我们探讨了一个人的大小和性别之间的关系，距离和频率，它从它的觅食区迁移到产卵地点，保真度特定的产卵地点和聚集产卵的个人的数量。为了实现这一点，406 C。在巴布亚新几内亚新不列颠Kimbe湾（5 ° 30'S 150 ° 6 'E）的近岸礁石上捕获并标记条纹鱼。标记的个体在空间离散但重叠的摄食区（最大直径平均值）内一直被观察到
Many coral reef fishes exhibit regular localised migrations between feeding and spawning areas, but the factors affecting these migration patterns, such as the distance, frequency and spawning site fidelity are poorly understood. The aim of this study was to investigate the patterns of migration to spawning sites of the surgeonfish, Ctenochaetus striatus (Acanthuridae). We explored relationships amongst an individual's size and sex, the distance and frequency it migrated from its feeding area to spawning sites, fidelity to particular spawning sites and the number of individuals that aggregated to spawn. In order to achieve this, 406 C. striatus were captured and tagged on inshore reefs in Kimbe Bay (5 degrees 30'S 150 degrees 6'E), New Britain, Papua New Guinea. Tagged individuals were consistently observed within spatially discrete but overlapping feeding areas (maximum diameter averaging
