Coastal fish diversity of the Socotra Archipelago, Yemen: Fishes Checklist

The Socotra Archipelago, located in the eastern Gulf of Aden, has a unique marine environment which combines tropical and ‘pseudo-temperate’ elements. Studies on the fish biogeography of the archipelago, partially framed in regional studies, have substantially outpaced critical elementary research on the archipelago’s fish diversity. The present study seeks to close this gap and identifies the Socotra Archipelago as a major hotspot of coastal fish diversity in the Indian Ocean. The archipelago supports unique coastal fish assemblages which are predominantly composed of coral-associated (“reef”) species, in spite of the limited biogenic reef frameworks. A Preliminary Checklist comprises 682 species with confirmed records and a “Working List” includes an additional 51 records, totalling 733 faunal records in 108 families.索科特拉群岛（Socotra Archipelago）坐落于亚丁湾东部，拥有兼具热带与“准温带”特征的独特海洋环境。此前针对该群岛的鱼类生物地理学研究（部分依托区域研究框架）已大幅领先于针对该群岛鱼类多样性的关键基础性研究。本研究旨在填补这一研究空白，并确认索科特拉群岛为印度洋沿岸鱼类多样性的核心热点区域。尽管该群岛的生物礁框架较为有限，但其孕育的独特沿岸鱼类群落仍以珊瑚关联（“礁栖”）物种为主体。本研究的初步名录（Preliminary Checklist）收录了682种已获确认记录的物种，另有“工作名录（Working List）”补充51条记录，总计涵盖108个科的733条动物区系记录。
