The composition of the larval fish assemblage in the sound-scattering layer of the continental shelf waters off the coast of south-eastern Brazil (12 and 22° S), a research project that is part of the Brazilian programme Avaliação do Potencial Sustentável de Recursos Vivos na Zona Econômica Exclusiva (REVIZEE), is described. Samples were collected during daylight hours and at dusk at five oceanographic stations in the winter of 1999 using an Isaacs-Kidd Midwater Trawl (IKMT). The oceanographic stations were chosen based on the detection of plankton layers by acoustic observation. A total of 2192 larval fish were identified, comprising 52 families and 62 species. Maurolicus stehmanni (Sternoptychidae) was the most abundant species found within the study area, comprising 18·5% of all identified larvae, followed by Psilotris celsus (Gobiidae) at 10·9%.
描述了巴西东南部海岸（南纬12度和22度）大陆架水域声学散射层中幼鱼组合的构成，该研究项目是巴西专属经济区生物资源可持续潜力评估计划（REVIZEE）的一部分。1999年冬季，在白天和黄昏时分，使用伊萨克斯-基德中层拖网（IKMT）在五个海洋学站点采集样本。这些海洋学站点是根据声学观测对浮游生物层的探测来选定的。共鉴定出2192尾幼鱼，分属52科62种。斯氏钻光鱼（光器鱼科）是研究区域内数量最多的物种，占所有鉴定出的幼鱼的18.5%，其次是高氏裸身鰕虎鱼（鰕虎鱼科），占10.9%。
