Résumé : A fish community was studied in Terminos Lagoon, Mexico over a one year period. Diurnal (24-h) and seasonal variations of several diversity indices - density, biomass, frequency and numerical abundance - were statistically related to changes in salinity, temperature, tide, and light periods. There were seasonal variations in all parameters of the community. The ecological parameters of the fish community remained high, reflecting a daily and seasonal succession of dominant fish species. The similarity in nichthemeral and seasonal changes exhibited by certain assemblages of species indicates that some dominant groups are influenced more by light period than by tidal stage. Community inhabitants and consumers of different trophic categories were seasonally quantified. Cyclical visitors (49%) and second-order consumers (49%) were dominant throughout the entire year. Twenty species were quantitatively important in terms of frequency, biomass and numerical abundance.
