description The composition, abundance and diversity of fishes in two reef patches located in Mochima National Park (Venezuela) were analyzed from January 2001 to January 2002. Monthly captures were made in deep zones. A total of 829 individuals were found and 67 species were recorded, of which 25 were common to both localities. In Cautaro, 547 specimens, belonging to 51 species and 24 families, were caught. The most abundant families were Scaridae (39.31%), Chaetodontidae (17.18%), Pomacentridae (13.89%), and Haemulidae (11.71%). Diversity ranged from 0.68 to 3.21 bits/ind, evenness from 0.29 to 0.98, and species richness from 0.68 to 2.24. Five of the species were permanent residents, seven were recurrent visitors and thirty-nine were occasional visitors. The most abundant species were Sparisoma aurofrenatum (39.31%), Chaetodon capistratus (16.27%) and Abudefduf saxatilis (13.89%). In Manzanillo, 282 specimens, belonging to 41 species and 21 families, were caught. The most numerous families were Sparidae (23.76%), Haemulidae (16.31%), and Chaetodontidae (11.70%). Diversity ranged from 1.00 to 3.22 bits/ind, evenness from 0.5 to 1, and species richness from 0.95 to 2.50. Three of the species were permanent residents, eight were recurrent visitors and thirty were occasional visitors. The most abundant species were Diplodus argenteus (23.76%), C. capistratus (11.70%), and Haemulon flavolineatum (11.34%). The higher species diversity found in Cautaro than in Manzanillo could be due to the higher structural complexity of the former.

Se analizó la composición, abundancia y diversidad de peces en dos parches coralinos en las localidades de Cautaro y Manzanillo del Parque Nacional Mochima (Venezuela), desde enero de 2001 hasta enero de 2002. Las capturas se efectuaron mensualmente en zonas profundas. Se recolectó un total de 829 individuos y se registraron 67 especies, de las cuales 25 fueron comunes a las dos localidades. En Cautaro, se capturaron 547 especímenes pertenecientes a 51 especies y 24 familias. Las familias más numerosas fueron Scaridae (39.31%), Chaetodontidae (17.18%), Pomacentridae (13.89%) y Haemulidae (11.71%). La diversidad fluctuó entre 0.68 y 3.21 bits/ind, la equitatividad entre 0.29 y 0.98, y la riqueza entre 0.68 y 2.24. Se determinó que 5 de las especies eran residentes permanentes, 7 eran visitantes cíclicos y 39 eran visitantes ocasionales. Las especies más abundantes fueron Sparisoma aurofrenatum (39.31%), Chaetodon capistratus (16.27%) y Abudefduf saxatilis (13.89%). En Manzanillo, se capturaron 282 peces pertenecientes a 41 especies y 21 familias. Las familias más numerosas fueron Sparidae (23.76%), Haemulidae (16.31%) y Chaetodontidae (11.70%). La diversidad mensual osciló entre 1.00 y 3.22 bits/ind, la equitatividad entre 0.50 y 1, y la riqueza entre 0.95 y 2.50. Se determinó que 3 especies eran residentes, 8 eran visitantes cíclicos y 30 eran visitantes ocasionales. Las más abundantes fueron Diplodus argenteus (23.76%), C. capistratus (11.70%) y Haemulon flavolineatum (11.34%). La mayor diversidad de especies en Cautaro puede explicarse por su mayor complejidad estructural en comparación con Manzanillo.
