México Jalisco composición específica de peces pesquería artesanal El Niño Oscilación del Sur captura por unidad de esfuerzo Mexico fish species composition small-scale fisheries El Niño southern oscillation catch per unit of effort In the tropical and subtropical coastal zone, were highly diverse fish communities occur, it is important to study the small scale fisheries exploiting these communities. For this study, 219 fishing days were carried out in Bahia de Navidad, Jalisco, Mexico. Four gillnets with different mesh sizes (76.2, 88.9, 101.6 and 114.3 mm) were used for the fishing operations, from April 1994 to March 1995 and from January 1998 to December 2000. A total of 26126 organisms weighting 11680 kg were caught. One hundred and eighty three species belonging to 57 families and 19 orders were identified. Ten species accumulated more than 60% of the total abundance and biomass, the remaining species (173) individually contributed with less than 2% of the total abundance and biomass. The most important species in the catch were Microlepidotus brevipinnis, Caranx caballus, Haemulon flaviguttatum, Scomberomorus sierra, C. caninus, C. sexfasciatus, Lutjanus guttatus and L. argentiventris. The catch per unit of effort showed a large var5287 mónica, biologíaiation during the study, both in number and biomass. On average, 110 fishes and 48.5 kg fishing day-1 were caught. The maximum values were recorded during January and October 1998 (250 fishes and 100 kg fishing day-1), and the minimum values were recorded during September and November 1994 (25 org. and 10 kg fishing day-1). The total abundance and biomass was lower during the 1994-95 period (F=6.16, 8.32, P < 0.05). There were statistically significant differences among the annual catch from each gillnet. All the environmental changes caused by the ENSO event had ecological and economic effects that can be rated from moderate to severe.
