Abstract

Zooplankton composition and abundance study from Chantuto and Panzacola estuarine systems, Chiapas, in dry (May of 1997) and rainy seasons (July of 1997) is presented. Zooplankton samples were taken using a standard net with 30 cm in mouth diameter and a mesh opening of 250 µm. Temperature, salinity, pH, and dissolved oxygen were measured in the water. The differences of the physical-chemical parameters among the dry and rainy seasons were found in the salinity averages, 23 to 13 psu respectively and in the percentages of oxygen saturation , 90 to 50 % respectively. Twenty species of zooplankton were identified, a genus of the Phylum Chaetognatha, 11 larval forms and several non identified species of fish eggs. In the dry season the copepods Canthocalanus pauper and Pseudodiaptomus culebrensis were dominant while in rainy season the dominant species was Oithona nana. None of the mentioned copepods had been considered before as dominants in Mexican estuarine systems.
