1. Marine protected areas (MPAs) are becoming a widely used tool for the conservation of biodiversity and for fishery management; however, most of these areas are designed without prior knowledge of the basic ecological aspects of the species that they are trying to protect.
2. This study investigated the movement of two top predators: the Galapagos shark, Carcharhinus galapagensis, and the yellowtail amberjack, Seriola lalandi, in and around the Motu Motiro Hiva Marine Park (MMHMP) using MiniPAT satellite tags to determine the effectiveness of this MPA for the protection of these species.
3. The Galapagos sharks (n = 4) spent most of their tag deployment periods inside the MMHMP. However, high intraspecific variability was observed in their movement dynamics. Daily individual maximum movements ranged from 17 to 58 km and the maximum distance from Salas y Gómez Island, the only emergent island within the MMHMP, ranged from 31 to 139 km.
4. The maximum linear distance travelled for a female juvenile Galapagos shark (152 cm total length) was 236 km, which is greater than the maximum distance previously documented for juveniles of this species (<50 km).
5. For the yellowtail amberjack (n = 1), 91% of the satellite geolocations were within the MMHMP, with a maximum daily distance travelled of 6 km. The maximum distance travelled between points was 111 km and the maximum distance from Salas y Gómez Island was 62 km.
6. All archival tagged fish spent most of their time at depths of <50 m and never left the epipelagic zone. Daytime versus night‐time differences were pronounced in all individuals but showed high interindividual variability.
7. This study provides a baseline on the movement of these two top predators in the MMHMP and provides valuable insights for the creation of MPAs in the region and elsewhere.

智利最偏远的海洋保护区中顶级掠食者的迁徙活动：对加拉帕戈斯鲨鱼，加尔加斯鲨鱼和黄尾a鱼（Seriola lalandi）的保护意义

1. 海洋保护区正在成为保护生物多样性和渔业管理的一种广泛使用的工具；但是，大多数这些区域在设计时都没有事先了解他们要保护的物种的基本生态方面的知识。
2. 这项研究使用MiniPAT卫星标签调查了Motu Motiro Hiva海洋公园（MMHMP）及其周围的两个顶级捕食者的运动：加拉帕戈斯鲨鱼（Carcharhinus galapagensis）和黄尾a（Seriola lalandi），以确定该MPA对捕食者的有效性。保护这些物种。
3. 加拉帕戈斯鲨鱼（n = 4）在MMHMP内度过了大部分标签部署时间。但是，在它们的运动动力学中观察到了较高的种内变异性。每日个人最大运动范围为17至58公里，而距MMHMP内唯一出现的岛屿Salas yGómez岛的最大距离为31至139公里。
4. 雌性加拉帕戈斯幼鲨的最大线性距离（总长152 cm）为236 km，大于先前记录的该物种少年的最大线性距离（<50 km）。
5. 对于黄尾a（n = 1），91％的卫星地理位置位于MMHMP内，最大每日行进距离为6 km。两点之间的最大距离为111公里，到萨拉斯·戈麦斯岛的最大距离为62公里。
6. 所有带有档案标记的鱼大部分时间都在小于50 m的深度上度过，并且从未离开过上层带。在所有个体中白天与夜间的差异均明显，但个体间差异较大。
7. 这项研究为MMHMP中这两个顶级捕食者的运动提供了基线，并为在该地区和其他地方建立MPA提供了宝贵的见解。
