Monthly sampling in 21 sites in the Cuyutlán Lagoon, México were carried out from March toJune 1999 and October 1999 to December 2000, where 1,719 fish from 22 families were collected. The most abundant were: yellowfin mojarra (Gerres cinereus) with 43.86 %, white mullet (Mugil curema) in 24.89 %, mojarra (Diapterus peruvianus) with 6.34 %, Pacific thread herring (Opisthonema libertate) with 5.29 % and with 3 % Pacific crevalle jack (Caranx caninus) and longjaw leatherjack (Oligoplites altus). The specific richness changed from 3.52 in May 1999 to 15.48 in October 2000. The equitativity fluctuated from 0 in the 18th station named Palo Verde to 0.93 in the 20th site in the same area. The diversity index presented valuesfrom 0.33 in May 1999 to 1.06 in October 2000. By its physical and biological characteristics the lagoon can be divided into two different areas. The opening of the channel Boca de Tepalcates increased the diversity of species of fish, but it will take time to know how the biomass is going to change.
