These data describe the species richness and abundance as part of MCR LTER's reef fish monitoring program to track long-term patterns in species abundance and diversity. This study began in 2000 in the lagoons off of the north shore of the island of Moorea, French Polynesia and the dataset is updated annually. The abundance and life history stage (adults, juveniles or recruits) of all taxa of fishes associated with selected colonies (5-16 colonies per site) of the mound forming coral Porites rus are recorded at seven reef sites located along the north shore of Moorea. These sites are characterized by differences in water depth, distance to the fore reef and the number and types of neighboring corals. Counts are performed by a pair of divers using SCUBA and include semi-cryptic species. The collection of these data was suspended following the last survey conducted in July 2011 due to the extremely low abundance of live P. rus at these locations.
