尽管国际沃茨覆盖了世界上60%以上的海洋,但对这些地区的渔业如何塑造生态系统过程的了解却令人惊讶地贫乏。海鸟在渔船上觅食,这对其种群有潜在的有害影响,但对与船只有关的重叠程度和行为知之甚少。我们使用新型生物记录设备,探测雷达辐射并记录船只和海鸟的位置,测量海鸟和渔船重叠的真实程度,并对国际沃茨的捕捞强度和船只分布情况作出估计。在繁殖期间,来自克罗泽群岛的流浪信天翁(Diomedea exulans)在距离殖民地2500公里的地方巡逻了1000多万平方公里的区域。高达79.5%的记录器连接到鸟类检测船只。信天翁和渔业之间的重叠程度对海鸟的副渔获物风险具有广泛的影响,并揭示了整个海洋的密集捕鱼区。我们认为,配备雷达探测器的海鸟是监测南大洋船只存在的极好工具,为监测非法捕捞活动的存在和更好地了解捕捞活动对海鸟的影响提供了一种新方法。 文章影响声明:安装在受威胁信天翁上的新记录仪检测和定位船只的雷达辐射,以估计南大洋的渔业范围。
Despite international waters covering over 60% of the world's oceans, understanding of how fisheries in these regions shape ecosystem processes is surprisingly poor. Seabirds forage at fishing vessels, which has potentially deleterious effects for their population, but the extent of overlap and behavior in relation to ships is poorly known. Using novel biologging devices, which detect radar emissions and record the position of boats and seabirds, we measured the true extent of the overlap between seabirds and fishing vessels and generated estimates of the intensity of fishing and distribution of vessels in international waters. During breeding, wandering albatrosses (Diomedea exulans) from the Crozet Islands patrolled an area of over 10 million km2 at distances up to 2500 km from the colony. Up to 79.5% of loggers attached to birds detected vessels. The extent of overlap between albatrosses and fisheries has widespread implications for bycatch risk in seabirds and reveals the areas of intense fishing throughout the ocean. We suggest that seabirds equipped with radar detectors are excellent monitors of the presence of vessels in the Southern Ocean and offer a new way to monitor the presence of illegal fisheries and to better understand the impact of fisheries on seabirds. Article impact statement: New logger fitted on threatened albatrosses detects and locates radar emissions of boats to estimate fisheries extent in the Southern Ocean.
