随着河流洄游崩溃，淡水鱼类种群数量暴跌81%

* *Draft:* 《迁徙淡水鱼类全球评估》在巴西举行的CMS第十五次缔约方大会（COP15）上发布，发现迁徙淡水鱼类是全球受威胁最严重的物种之一。 * *Refinement:* "CMS" stands for Convention on the Conservation of Migratory Species of Wild Animals. In Chinese context, usually translated as "养护野生动物移栖物种公约" or simply "迁徙物种公约". I will use the full name or standard abbreviation context. Let's stick to "《养护野生动物移栖物种公约》（CMS）" for clarity or just "CMS" if the context allows. The text says "CMS 15th Meeting...", so "CMS第十五次缔约方大会". * *Continuation:* "These fish are critical for..." -> 这些鱼类对于维持河流健康、支持主要内陆渔业以及为数亿人提供食物和生计至关重要。 * *P2 (Heading):* "Hundreds of Migratory Fish Species Need Global Protection" * *Draft:* 数百种迁徙鱼类需要全球保护。 * *P3:* "The assessment highlights hundreds of migratory fish species that require coordinated international action." * *Draft:* 该评估强调有数百种迁徙鱼类需要协调一致的国际行动。 * *Continuation:* "It provides strong evidence that fish relying on connected rivers across national borders are declining quickly due to..." * *Draft:* 它提供了强有力的证据，表明依赖跨国界连通河流的鱼类正因大坝建设、栖息地破碎化、污染、过度捕捞以及与气候相关的生态系统变化而迅速减少。 * *P4:* "In total, 325 migratory freshwater fish species have been identified as candidates for international conservation efforts..." * *Draft:* 总共有325种迁徙淡水鱼类被确定为国际保护工作的候选对象，这表明跨界河流系统中存在一场很大程度上被忽视的生物多样性危机。 * *P5:* "A regional breakdown of the 325 migratory freshwater fish species deemed candidates for international protection (beyond the 24 already listed) under the Convention's Appendices I (species requiring strict protection) and II (species needing international cooperation):" * *Draft:* 根据该公约附录I（需要严格保护的物种）和附录II（需要国际合作的物种），被认定为国际保护候选对象的325种迁徙淡水鱼类的区域分布细目（除已列入的24种外）： * *注明:* The structure is a lead-in to a list. * *List:* * Asia: 205 -> 亚洲：205种 * South America: 55 -> 南美洲：55种 * Africa: 42 -> 非洲：42种 * Europe: 50 -> 欧洲：50种 * North America: 32 -> 北美洲：32种 * *P6:* "(The total adds to more than 325 because some species occur on multiple continents.)" * *Draft:* （总数超过325种，是因为某些物种出现在多个大陆。） * *P7:* "Key river systems identified as priorities include..." * *Draft:* 被确定为优先保护的重点河流系统包括南美洲的亚马逊河和拉普拉塔-巴拉那河、欧洲的多瑙河、亚洲的湄公河、非洲的尼罗河以及印度次大陆的恒河-布拉马普特拉河。 * *P8:* "Based on extensive global datasets and IUCN assessments of nearly 15,000 freshwater fish species..." * *Draft:* 基于广泛的全球数据集和IUCN对近15,000种淡水鱼类的评估，该报告提供了迄今为止关于迁徙淡水鱼类所面临保护挑战的最全面概述。 * *注明:* IUCN = 世界自然保护联盟. * *P9:* "It also outlines practical steps governments can take immediately, including:" * *Draft:* 报告还概述了各国政府可立即采取的切实措施，包括： * *List:* * protection of migration corridors and environmental flows -> 保护迁徙走廊和环境流 * basin-scale action plans and transboundary monitoring -> 流域尺度的行动计划和跨界监测 * coordinated seasonal fisheries -> 协调的季节性渔业管理 * *P10 (Heading):* "A Largely Overlooked Freshwater Biodiversity Crisis" * *Draft:* 一场很大程度上被忽视的淡水生物多样性危机 * *P11:* "Animals living in freshwater ecosystems are declining faster than those on land or in the oceans..." * *Draft:* 生活在淡水生态系统中的动物数量下降速度比陆地或海洋中的动物更快，然而迁徙淡水鱼类的崩溃却相对较少受到全球关注。 * *P12:* "These fish depend on long, uninterrupted river pathways that link spawning grounds, feeding areas, and floodplain nurseries..." * *Draft:* 这些鱼类依赖于连接产卵场、觅食区和洪泛平原育幼场的漫长且不间断的河流通道，这些通道往往跨越多个国家。 * *Continuation:* "When dams, altered water flows, or habitat degradation disrupt these connections, populations can drop quickly." * *Draft:* 当大坝、水流改变或栖息地退化破坏了这些连接时，种群数量可能会迅速下降。 4. **Final Review:** * Check terminology: * "Migratory Freshwater Fishes" -> 迁徙淡水鱼类 (Standard). * "CMS" -> 《养护野生动物移栖物种公约》 (Standard full name, usually abbreviated as CMS in brackets or just CMS if context is clear.
