All carangid larvae used in this study are from the larval fish collection of the Zooplankton and Ichthyoplankton Integrated Laboratory of Federal University of Rio de Janeiro – Brazil (DZUFRJ). Carangid larvae were collected in 13 surveys (nine in the dry season and four during the rainy season) between 1998 and 2008, from Bahia (12°S) to Rio de Janeiro (23°S), comprising 158 sampling stations (45 coastal; 98 oceanic; 15 over seamounts). A bongo net with 330 and 500-μm mesh size was towed at a speed of about two knots, obliquely (surface-bottom-surface) from a maximum depth of 200 m. Samples were collected both during the day and at night and combined in the analysis. A total of 1321 carangid larvae were identified representing 14 species: Decapterus punctatus (56.7%), Chloroscombrus chrysurus (16.8%), Caranx crysos (8.4%), Selar crumenophthalmus (6.3%), Trachurus lathami (6.3%), Caranx latus (2.4%), Carangoides bartholomaei (1.3%), Oligoplites spp. (0.6%), Pseudocaranx dentex (0.3%), Seriola dumerili (0.2%), Elagatis bipinnulata (0.2%), Selene setapinnis (0.2%), Trachinotus carolinus (0.2%) and Selene vomer (0.1%). There was no significant difference in carangid density (P = 0.17) or in species composition (P = 0.09) among the coastal, oceanic and seamount stations. Although there was a significant difference in larval densities between the dry and rainy periods (P = 0.000264), the community composition did not vary significantly (P = 0.47). Therefore, seasonality (rainy and dry periods) seems to be the main factor affecting carangid densities although the community composition is not influenced by sampling periods or by the gradient coast-ocean.
