        Abstract

        To determine the structure of the ichthyoplankton assemblage
        along a saline gradient in the Pánuco river estuary, sampling was
        performed in: January, March, May, July, September, and November in 2017
        at nine sites, with a standard network with a mesh opening of 500 μm. 1
        165 eggs and 526 fish larvae were collected from 18 species, three of them
        from freshwater. The highest specific richness was observed in the middle
        estuary and lagoon of Pueblo Viejo. The highest values of diversity and
        evenness was found in November (2.7 and 0.9, respectively). The dominance
        was greatest in July (0.4) due to the abundance of Anchoa mitchilli.
        The ichthyoplankton assemblage was characterized by a greater number of
        dominant marine and estuarine species, a low number of freshwater species
        and a decrease in species richness upstream.
