description	The Petenes Biosphere Reserve (RBLP) is located on the coast of Campeche in the Gulf of Mexico. In this ecosystem nektonic fauna is distinguished for its abundance and diversity as well as the wide seagrasses beds. The purpose of the present work was to analyze the dominant fish associations in a variable environment (dry and rainy season) and a nycthemeral framework. Six sampling campaigns were made in a site located near Jaina Island in the central region of the RBLP between December 2010 and October 2011. In a period of 24 h biological samples were collected every 2 h, and temperature, salinity, dissolved oxygen and pH were measured. All fishes were identified and the dominant species were determined. Statistical techniques of classification and ordering were applied in order to analyze the interspecific associations and the correlations between species abundance and environmental variability. A total volume of 10 602 fish weighing 163.62 kg were captured, identifying 44 species, grouping them in 33 genera and 23 families, 14 of which resulted dominant. Haemulon plumierii was outstanding for its abundance. The canonic correspondence analysis for dry season emphasized the relationship between salinity and pH with the abundance of Eucinostomus gula, Acanthostracion quadricornis and Haemulon aurolineatum. For the rainy season, the relationship between dissolved oxygen and Lagodon rhomboids is evident. There were no significant statistical differences between the groups by climatic period.

La Reserva de la Biósfera Los Petenes (RBLP) se localiza en la costa de Campeche, en el Golfo de México. En este ecosistema destacan la fauna nectónica por su abundancia y diversidad, y la amplia cobertura de pastos marinos. El objetivo del presente trabajo fue analizar las asociaciones de los peces dominantes en un marco de variabilidad ambiental temporal (época de secas y época de lluvias) y nictemeral (día y noche). Se realizaron seis campañas de muestreo entre diciembre 2010 y octubre 2011, en un sitio ubicado cerca de Isla Jaina en la región central de la RBLP. Se recolectaron muestras biológicas cada 2 h en un período de 24 h y se realizaron mediciones de temperatura, salinidad, oxígeno disuelto y pH del agua. Se identificaron todos los peces, determinando a las especies dominantes. Las asociaciones interespecíficas y las relaciones entre abundancia y variables ambientales se establecieron mediante técnicas estadísticas de clasificación y ordenación. Se capturaron 10 602 peces con un peso conjunto de 163.62 kg, identificando 44 especies, agrupadas en 33 géneros y 23 familias, de las cuales, 14 resultaron dominantes, destacando la abundancia de Haemulon plumierii. Los dendrogramas específicos construidos por época climática y ciclo nictemeral permitieron identificar tres grupos funcionales. El análisis de correspondencias canónicas para la época de secas destacó relaciones entre salinidad y pH con la abundancia de Eucinostomus gula, Acanthostracion quadricornis y Haemulon aurolineatum. En la época de lluvias, se asoció el oxígeno disuelto con Lagodon rhomboides. No se encontraron diferencias significativas entre las agrupaciones por época climática.
