偏远的太平洋岛屿保护活跃的鲨鱼种群,但沿海海洋保护区因执法不力和过度捕捞而失败。 Remote Pacific islands protect thriving shark populations, but coastal MPAs fail due to weak enforcement and overfishing.

对东热带太平洋七个海洋保护区进行的一项新研究发现,加拉帕戈斯、马尔佩洛、克利珀顿和Revillagigedo等边远海洋岛屿由于强有力的保护和孤立,支持鲨鱼群,包括濒危物种,蓬勃发展。 A new study of seven marine protected areas in the Eastern Tropical Pacific finds remote oceanic islands like the Galápagos, Malpelo, Clipperton, and Revillagigedo support thriving shark populations, including endangered species, due to strong protection and isolation. 相反,厄瓜多尔、哥斯达黎加、哥伦比亚和墨西哥的沿海海洋保护区显示,由于长期过度捕捞和执法不力,大型掠食性鱼类数量大幅减少。 In contrast, coastal MPAs in Ecuador, Costa Rica, Colombia, and Mexico show drastically reduced numbers of large predatory fish, likely from long-term overfishing and weak enforcement. 研究人员利用诱饵水下摄像头记录偏远地区健康鲨鱼种群,包括表示有育婴功能的少年,而沿海地点很少看到鲨鱼。 Researchers used baited underwater cameras to document healthy shark populations in remote areas, including juveniles suggesting nursery functions, while coastal sites had few shark sightings. 研究结果强调,有效的海洋保护不仅需要指定,而且需要强有力的执法,特别是在易受非法捕捞和污染影响的近岸地区。 The findings highlight that effective marine protection requires more than just designation—it demands robust enforcement, especially in nearshore zones vulnerable to illegal fishing and pollution.
