Abstract

This study describes the taxonomic composition and horizontal distribution of Serranidae larvae along the Southeastern Brazilian Bight (SBB, approximately 22°S and 28°S), and investigates how environmental and biological factors influence the larval distribution. Ichthyoplankton samples were collected in 10 oceanographic cruises conducted from 1975 to 1981. Serranidae larvae were identified into 15 species, including 11 genera and four subfamilies. Except for Diplectrum formosum, which was widely distributed throughout the SBB, Hyporthodus spp. and Baldwinella vivanus were distributed in the southern portion of the SBB, while other species were distributed mainly in the northern portion of the SBB, inside the 200 m isobath. Local depth, latitude, distance from the closest island and salinity were factors that influenced significantly on the distribution and abundance of the most abundant taxa D. formosum, Diplectrum spp., Serranus spp. and Mycteroperca spp. Significant progress was made in identifying grouper larvae from the SBB (Epinephelus morio, Epinephelus itajara and Hyporthodus nigritus).

巴西湾东南部Serranidae（放线菌目：鲈形目）幼虫的组成和分布

本研究描述了巴西东南湾(SBB，约22°S和28°S) Serranidae幼虫的分类组成和水平分布，并探讨了环境和生物因素对幼虫分布的影响。在1975年至1981年期间进行了10次海洋考察，收集了浮游鱼样本。蚕科幼虫鉴定为4亚科11属15种。除广泛分布于南海带内的formosum Diplectrum外，主要分布在南海带南部的hypthodus spp.和Baldwinella vivanus .，其他种类主要分布在南海带北部200 m等深线内。当地深度、纬度、离最近岛屿的距离和盐度是影响最丰富的分类群D. formosum、Diplectrum spp.、Serranus spp.和Mycteroperca spp分布和丰度的主要因素，对SBB石斑鱼幼虫(Epinephelus morio、Epinephelus itajara和Hyporthodus nigritus)的鉴定取得了重大进展。Mariana Rodrigues dos-Santos1*， Mario Katsuragawa1, Maria de Lourdes Zani-Teixeira1, Jana Menegassi del faver2

期刊介绍： The Brazilian Journal of Oceanography covers the entire spectrum of disciplines within the science of oceanography, publishing articles dealing with the biological oceanography, physical oceanography, marine chemistry, sedimentology and geology, from coastal and estuarine waters out to the open sea. Emphasis is placed on inter-disciplinary process-oriented contributions. BJO also publishes issues dedicated to results of scientific meetings and of large inter-disciplinary studies or topical issues on specific subjects. The audience is composed by physical, chemical and biological oceanographers, marine sedimentologists, geologists and geochemists, marine biologists and ecologists. Papers sent to BJO must present results from original research and be written in english.
