| Sumario: | Many rocky reefs exist in the Gulf of California; however, there are few studies on the fish communitiesthat inhabit them. In the present work, these communities are evaluated through visual censusesat four sites of the southwestem coast of the gulf. The specifíc richness, frequency, evenness anddiversity were analyzed at each site. Seasonal changes and differences among the sites studied werealso analyzed. A total of 76 species was registered. Five species were the most abundant in most ofthe zones and during the greater part of the study: Stegastes spp., Thalassoma lucasanum, Abudefduftroschelii, Chromis atrilobata and Haemulon maculicauda. Only the tirst three species were present inall censuses made. Differences were found in the structure of the communities between differentseasons and between study sites; however, the diversity values had no significant differences. Thezone with the greatest number of species was Cueva de León. A positive relationship was foundbetween specific richness and temperature. |
