Abstract

Inorder to know the possible larval sizes vertical distribution pattern of Sciaenidae family in the southern Gulf of Mexico, larvae from 22 stations distributed in 4 transects located off Del Carmen and Machona Lagoons, Términos Lagoon and Grijalba-Usumacinta system, was analysed. Sampling was carried out during spring season, with open-close nets; 75 cm mouth diamenter, 235 cm length nad 505 mm mesh. The sampled layers in the water column were taken on the following ranges: 0-6 m, 6-12 m, 12-16 m, 45-55 m and 95-105 m depth. Salinity and temperature data were recorder from the water column at every station. A total of 294 Sciaenidae larvae were caught, blonging to the taxa: Cynoscion arenarius (56.0%), Stellifer lanceolatus (13.0%), Menticirrhus spp. (12.2%), Cynoscion nothus (10.15), Larimus fasciatus (1.0%) y Micropogonias spp. (0.9%). Larvae of these taxa occurred on the inner continental shelf, ca. 50 km from de the coastline mainly in areas between 18-36 m depth, and they were caugh only in the surface layer or in coastal stations.  The larvae vertical distribution shown that 81.4% occurred at 6-12 m depth, 15.9% at the surface layer and only four larave at 12-18 m layer. In the study period the larvae of this family dwell above 20 m depth and esentially correspond to larvae less than 3 mm, in preflexion and flexion stages.
