This study reports the results of 5 years of monitoring reef fish post-larvae using light traps in the Bay of Tamandaré, north-east Brazil. An annotated checklist of pre-settlement fish species, their frequency of occurrence and taxonomic characteristics are provided. In total, 4,422 post-larval fishes belonging to 36 families, 56 genera and 76 species were captured. The most species-rich families were Carangidae (7), Lutjanidae (6) and Pomacentridae (4), while the families Gerreidae (30.47%), Holocentridae (16.54%), Blenniidae (12.01%), Labrisomidae (8.36%), Lutjanidae (8.29%) and Acanthuridae (5.95%) were the most abundant. This is the first study of the taxonomic diversity and assemblage structure of settlement-stage reef fishes in the tropical south-west Atlantic Ocean. Although a few common species were not captured due to selectivity of light traps, the composition and taxonomic diversity of this first collection suggests that light traps are useful for studies of the early life history of a wide range of pre-settlement reef fishes.
本研究报告了在巴西东北部塔曼达雷湾使用灯光诱捕器对珊瑚礁鱼类幼体进行5年监测的结果。提供了一份关于定居前鱼类物种的注释清单，包括它们的出现频率和分类特征。总共捕获了属于36科、56属和76种的4422尾幼体鱼类。物种最丰富的科是鲹科（7种）、笛鲷科（6种）和雀鲷科（4种），而银鲈科（30.47%）、金鳞鱼科（16.54%）、鳚科（12.01%）、唇齿鳚科（8.36%）、笛鲷科（8.29%）和刺尾鱼科（5.95%）是数量最多的科。这是对热带西南大西洋定居阶段珊瑚礁鱼类分类多样性和群落结构的首次研究。尽管由于灯光诱捕器的选择性，一些常见物种未被捕获，但这第一批收集样本的组成和分类多样性表明，灯光诱捕器对于研究广泛的定居前珊瑚礁鱼类的早期生活史很有用。
