The ichthyofauna obtained in 1998 by riparian fishing in Barra de Navidad, Jalisco, Mexico was quantified. 6 944 organisms belonging to 130 species were caught and weighted. 30% of the species belonged to Carangidae, Haemulidae and Sciaenidae families. The most important species in number and biomass were Microlepidotus brevipinnis, Caranx caninus and C. caballus. Species number, abundance and biomass fluctuated during the year. The largest number of species was caught in June (61), the minimum in March (33). January had the maximum abundance (1 397 organisms), while the minimum was obtained during August (251). The maximum biomass values were from January (556.5 Kg), and the lowest from August (114.7 Kg). Eighteen species accumulated 87% of the total abundance, while 20 species represented 86.3% of the biomass. There were large in differences species number, abundance and biomass nets of different mesh size.
