Structure of the fish community at a reef in Los Monjes Archipelago, Venezuela

In order to determine the community structure of reef fishes, visual counts were made along a transect established in a section of Monje Grande del Sur Island (Venezuela). A total of 57 fish species were identified. The families with the highest number of species were Pomacentridae (6), Scaridae (6)...

A total of 57 fish species were identified. The families with the highest number of species were Pomacentridae (6), Scaridae (6), Labridae (6) and Serranidae (5), while the families with the highest total number of individuals were Pomacentridae (2083), Labridae (513), Hemiramphidae (440) and Scaridae (246), with 79.9% of the 4105 individuals observed. Though most of the fish species were carnivorous, the planktivors Chromis multilineata (23.7%) and Stegastes partitus (19.4%) were the two most numerically important species. In general, our results suggest a different species composition of reef fishes compared with other coralline regions of Venezuela. Some commercial fish species that are subject to intense fishing activities elsewhere (e.g., Sphyraena barracuda) were also found. En un sector del Monje Grande del Sur (Venezuela) se delimitó un transepto, a lo largo del cual se hicieron censos visuales con el propósito de determinar la estructura de la comunidad de peces allí presente. Se identificó un total de 57 especies de peces. Las familias con mayor número de especies fueron Pomacentridae (6), Scaridae (6), Labridae (6) y Serranidae (5), mientras que las familias con mayor número total de individuos fueron Pomacentridae (2083), Labridae (513), Hemiramphidae (440) y Scaridae (246), agrupando 79.9% de los 4105 individuos censados. Aunque la mayoría de las especies resultaron ser carnívoras, fueron los planctívoros como Chromis multilineata (23.7%) y Stegastes partitus (19.4%) los que presentaron mayor importancia numérica. En general, los resultados manifiestan una estructura en la comunidad de peces diferente a la de otras zonas oralinas en el país. Además, se encuentran especies de interés comercial y poblaciones importantes de algunos taxa que están siendo objeto de amplia explotación en otros lugares (e.g., Sphyraena barracuda).
