Shark sanctuaries are an ambitious attempt to protect huge areas of ocean space to curtail overfishing of sharks. If shark sanctuaries are to succeed, effective surveillance and enforcement is urgently needed. We use a case study with a high level of illegal shark fishing within a shark sanctuary to help motivate three actionable opportunities to create truly effective shark sanctuaries by leveraging satellite technology: (1) require vessel tracking systems; (2) partner with international research organizations; and (3) ban vessels previously associated with illegal fishing from shark sanctuaries. Sustaining the level of fishing mortality observed in our case study would lead even a healthy shark population to collapse to <10% of its unfished state in fewer than five years. We outline implementations pathways and provide a roadmap to pair new and emerging satellite technologies with existing international agreements to offer new hope for shark conservation successes globally.

利用卫星技术创建真正的鲨鱼保护区

鲨鱼保护区是一项雄心勃勃的尝试，目的是保护广阔的海洋区域，以减少鲨鱼的过度捕捞。如果要成功地建立鲨鱼保护区，那么迫切需要有效的监视和执法。我们使用一个案例研究来研究鲨鱼保护区内的大量非法鲨鱼捕捞活动，以利用卫星技术来帮助激发三个切实可行的机会来创建真正有效的鲨鱼保护区：（1）需要船只跟踪系统；（2）与国际研究组织合作；（3）禁止以前与鲨鱼保护区非法捕鱼有关的船只。维持我们的案例研究中观察到的捕捞死亡率水平，甚至会导致健康的鲨鱼种群在不到五年的时间内崩溃到其未捕捞状态的<10％。
