本研究的目的是证明使用 COI 序列识别的鱼类幼虫为提高对当地鱼类丰富度的了解提供了独特的机会。 2014年10月至2015年3月，在印度洋西南部留尼汪岛西海岸，使用光诱器在中上层阶段末期对鱼类幼虫进行采样，每月一次。在捕获的5174只幼鱼中，选择了214个形态不同的标本，其中196个成功加了条形码，总共提供了101个不同的条形码索引号（BIN）。在这些 BIN 中，有 55 个从未在留尼旺专属经济区 (EEZ) 记录过，13 个是 BOLD 数据库中新添加的。即使在本研究期间收集鱼类幼体的采样工作量相对较低，它也允许在留尼旺专属经济区更新的鱼类清单中添加至少九个新物种。
The aim of this study was to demonstrate that fish larvae identified using their COI sequences offer a unique opportunity for improving the knowledge of local fish richness. Fish larvae were sampled at the end of their pelagic phase using light-traps set off the West Coast of La Reunion Island, southwestern Indian Ocean, once per month from October 2014 to March 2015. Among the 5174 larvae caught, 214 morphologically different specimens were selected, 196 successfully barcoded, giving a total of 101 different Barcode Index Numbers (BINs). Among these BINs, 55 had never been recorded in La Reunion exclusive economic zone (EEZ), and 13 were new for the BOLD database. Even if the sampling effort for collecting fish post-larvae during this study was relatively low, it allowed adding at least nine new species to an updated checklist of fishes of La Reunion EEZ.
