尽管湄公河下游流域的洄游鱼类具有重要的经济和生态意义，但对它们的研究仍然不足，这阻碍了有效的管理，以维持有价值的渔业，并解决栖息地退化、开发和过度捕捞等严重威胁。从潜在的知识需求列表中，一组渔业专业人员最频繁地确定了柬埔寨洄游鱼类管理的六个优先事项：(1)种群丰度和趋势，(2)生命周期和生活史，(3)洄游时间和触发因素，(4)洄游路线和距离，(5)主要栖息地和产卵区的位置，以及(6)环境和栖息地要求。这些需求与解决这些需求的九种相关方法一起进行了讨论，包括依赖渔业和独立渔业的抽样、生殖技术和圈养研究、耳石和遗传分析工具，以及标记和成像技术。提出了一个建议的研究框架，为洄游鱼类的适应性管理提供信息。虽然重点放在柬埔寨，但该分析也适用于其他LMB国家，因为洄游鱼类在整个流域都有，并跨越边界洄游。建议需要一个强有力的研究和监测议程，以便优先考虑知识需求并选择适当的方法来回答对柬埔寨可持续洄游鱼类管理至关重要的问题。
Despite their economic and ecological importance, migratory fishes of the Lower Mekong Basin (LMB) remain understudied, which hampers effective management to sustain valuable fisheries and address serious threats such as habitat degradation, development and overharvest. From a list of potential knowledge needs, a group of fisheries professionals most frequently identified six top priorities for managing migratory fishes in Cambodia: (1) population abundances and trends, (2) life cycles and life history, (3) migration timing and triggers, (4) migration routes and distances, (5) locations of key habitats and spawning areas, and (6) environmental and habitat requirements. These needs are discussed along with nine relevant methodologies for addressing them, including fisheries‐dependent and fisheries‐independent sampling, reproductive techniques and captive studies, otolith and genetic analysis tools, and tagging and imaging techniques. A suggested research framework is also presented to inform adaptive management of migratory fishes. While emphasis is given to Cambodia, the analysis is also applicable to other LMB countries, given that migratory fishes occur throughout the basin and migrate across borders. It is suggested that a robust research and monitoring agenda is required to prioritise knowledge needs and select appropriate methodologies to answer questions vital to inform sustainable migratory fish management in Cambodia.
