Recently, the global state of marine fisheries and its effects on ecosystems have received much scientific (and public) scrutiny. There is little doubt that global limits to exploitation have been reached and that recovery of depleted stocks must become a cornerstone of fisheries management. Yet, current trends appear to be diverging between well-assessed regions showing stabilization of fish biomass and other regions continuing to decline. This divergence can be explained by improved controls on exploitation rates in several wealthy countries, but low management capacity elsewhere. Here, we identify an urgent need to direct priorities towards 'fisheries-conservation hotspots' of increasing exploitation rates, high biodiversity, and poor management capacity, and conclude that the future of fish depends, at least in part, on redoubling science, co-management and conservation efforts in those regions.
最近,海洋渔业的全球状况及其对生态系统的影响受到了科学界(和公众)的广泛关注。毫无疑问,全球渔业资源的开发已经达到了极限,恢复枯竭的鱼类种群必须成为渔业管理的基石。然而,目前的趋势似乎在两种情况之间出现了分化:评估较好的地区鱼类生物量趋于稳定,而其他地区仍在继续下降。这种分化可以用一些富裕国家对捕捞率的控制有所改善来解释,但其他地区的管理能力却很低。在这里,我们认为迫切需要将重点放在捕捞率不断提高、生物多样性高和管理能力差的“渔业保护热点地区”上,并得出结论,鱼类的未来至少部分取决于在这些地区加倍努力开展科学研究、共同管理和保护工作。
