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.
