This study aims to determine the community structure changes and to determine the abundance of herbivorous fish and coralivorous fish in Krueng Raya waters during and after the occurrence of coral bleaching. This research was conducted in three stages: June 2016, October 2016, and February 2017. There are 3 locations for data collection, including Benteng Inong Balee, Ahmad Rhang Manyang, and Lhok Mee in Mesjid Raya Sub-District, Aceh Besar District. Reef fish abundance data were collected at a depth of 36 meters using the visual census technique (VCT) -belt transect method. The study results show that there were six families, 17 genera, and 47 species belonging to the herbivorous and coralivorous fish groups. The mostabundantfamilywasthe Chaetodontidae family,while the leastfishfamily wasthe Kyphosidae family. The highest abundance of corallivorous fish was found at station 2 in October 2016, with a value of 509 ind/ha. The lowest was found at station 3 in October 2016, with a value of 182 ind/ha. The highest abundance of herbivorous fish was found at station 3 in February 2017, with a value of 498 ind/ha. The lowest was found at station 3 in October 2016, with a value of 150 ind/ha.
