Karimunjawa is one of the National Parks in Indonesia, a marine conservation area known for its diverse coral reefs, and mangrove forest. This study aims to determine coral reef status in Menyawakan Island at the northwest part of Karimunjawa Archipelago. Coral coverage as well as reef fish data were collected from the South, West, North, and East side of Menyawakan Island. Surveys were conducted at a depth of 5 and 10 meters, using the Line Intercept Transect (LIT) for coral coverage and visual census for reef fish abundance. The highest coral cover, categorized as good condition, was found in the North side of Menyawakan Island at a depth of 5 m (64.94%). Pomacentrus shows the greatest abundance with 291 individuals on the South side of Menyawakan Island. Overall coral cover in Menyawakan Island is categorized as medium to good condition, while the highest reef fish abundance is dominated with family of Pomacentridae , which are native habitat in coral reef area.
