Abstract

The richness of aquatic snails was determined, on two basin of the state of Tabasco, samples were taken at 23 locations during two seasons, the rainy season (September and October 2008) and the dry season (April and May 2009). The organisms were collected from the roots of Rhizophora mangle (red mangrove) and those adhered to Eichhornia crassipes (water hyacinth). Thirteen gastropods and three bivalves associated with water hyacinth as well as four gastropods and four bivalves from mangrove roots were collected. The CH Grijalva River-Villahermosa present he highest species richness 21 and 20 species were within the Subc. Carrizal River 52.17% of the species were from freshwater and collected on water lily; 30.44% were collected were brackish and collected on mangrove roots; 17.39% on euryhaline and harvested on both vegetation types. As for the estimation of richness, a difference of one to five species was observed between then species richness estimated and that estimated with SChao2. Of the 23 species recorded in this study none are listed in the NOM-059-SEMARNAT-2010. The most abundant freshwater species on the two basins were Pyrgophorus coronatus, Mexinauta impluviata, Littoridinops tenuipes, Mayabina polita and Pomacea flagellata; and brackish Mytilopsis leucophaeata, Brachidontes exustus, Littorina angulifera, Neritina virginea and Musculium transversum. The greatest richness and abundance of molluscs associated with both E. crassipes as R. mangle were present during the rainy season.
