长期以来，科学家们一直试图揭开安圭拉鳗属的迁徙秘密。作为地栖鱼类，鳗鳗一生大部分时间都生活在淡水中，直到它们回到热带的产卵地，尽管有一部分鳗鳗从不进入淡水，而是生活在靠近海岸线的咸淡水和海洋地区。分子系统发育研究表明，鳗鲡起源于深海中水海洋鳗鲡类，起源于印度-太平洋地区的热带鳗鲡是鳗鲡的最基础种。鳗鲡离开热带海洋到温带地区定居。热带物种每年的产卵和全年不断的幼虫生长延伸到大陆栖息地的招募期，对热带鳗鱼来说，这将持续一年。热带鳗鱼如A. celebesensis和A. borneensis的迁徙期相对较短，到产卵地的迁徙期不到100公里。相反，温带欧洲鳗鲡（A. anguilla）的迁徙距离最长，跨越大西洋迁徙5000多公里，在马尾藻海产卵。安圭拉属鱼类的祖先迁徙状态可能是地方性的、短期的、非季节性的、全年的洄游，如热带鳗鱼所定义的那样。随着全球海洋移民在世界范围内分散的扩大，移民规模会逐渐发生变化。温带鳗鲡从产卵区向沿海和内陆水域栖息地迁移数千公里，同时在热带地区保留产卵区，伴随着季节性下游和产卵迁徙，造成季节性招募的后果。最近的研究进展以及弹出式卫星档案标签等电子标签的可用性可以重建从大陆生长栖息地到产卵地点的整个产卵迁徙过程，并提供详细的迁徙行为和路线。近几十年来，鳗鲡洄游生态和洄游机制逐渐得到揭示。安圭拉、地下环境、大陆迁徙、多样性、海洋迁徙、产卵、农业科学、动物科学、环境科学、生态学、生物科学、动物学。
Scientists have long sought to uncover the secrets of the migration of anguillid eels, genus Anguilla. As catadromous fishes, anguillid eels spend most of their lives in freshwater until they return to their spawning grounds in the tropics, although part of the population never enters freshwater and instead resides in brackish and marine areas close to coastlines. Molecular phylogenetic research suggests that anguillid eels originated from deep-ocean midwater marine anguilliform species and that tropical eels originating from the Indo-Pacific region are the most basal species of anguillid eels. Anguillid eels left the tropical ocean to colonize temperate areas. The yearly spawning of tropical species and constant larval growth throughout the year extend to periods of recruitment in continental habitats to last all year for tropical eels. Tropical eels such as A. celebesensis and A. borneensis have relatively short migrations periods of less than 100 km to their spawning grounds. Conversely, the temperate European eel A. anguilla travels the longest distances and migrates more than 5000 km across the Atlantic Ocean to spawn in the Sargasso Sea. The ancestral state of migration in the genus Anguilla may have been local, short-scale and nonseasonal spawning migration throughout the year as defined in tropical eels. With the expansion of dispersion of global oceanic migration across the world, migration scales can gradually change. Temperate anguillid eels migrate thousands of kilometres from spawning areas to coastal and inland water habitats while retaining spawning areas in tropical areas, accompanied by seasonal downstream and spawning migrations with consequences for seasonal recruitment. Recent advances and the availability of electronic tags such as pop-up satellite archival tag could reconstruct the entire spawning migration from continental growth habitats to spawning sites with detailed migration behaviours and routes. Migration ecology and mechanisms throughout the life of anguillid eels have gradually been revealed in recent decades.
