Abstract
The analyzed samples of plankton in this study were taken from oceanographic research R/V ONJUKU throughout the Yucatan shelf during September 2003. 45 stations were covered. For collecting the samples superficial tows were made with a 61 cm Bongo net fitted with 303 and 505 mm mesh netting. This work had the objective of analyzing the abundance and distribution of larvae of the families Serranidae and Lutjanidae. The Serranidae family is represented with 5 genuses (Anthias, Diplectrum, Epinephelus, Liopropoma and Serranus), 1 species (Epinephelus fulvus) with a total of 72 organisms, whereas the lutjanidae family is represented by 1 genus (Lutjanus) with 4 species (L. analis, L. campechanus, L. griseus, L synagris) and 125 total organisms. The most abundant species of the groupers was Epinephelus fulvus (30 organisms) and for the snappers it was Lutjanus synagris (57 organisms). The serranid larvae are distributed in the West zone and those of lutjanidos mainly in the East zone of the Yucatan shelf. Spatial distribution pattern of larvae was related to local oceanographic processes.
