Community Structure Of Reef Fish In Eastern Luwu Water Territory

One bio-indicators the condition of coral reefs is a presence of reef fish. The purpose of research is to determine species composition, abundance, distribution and structure of reef fish communities in these waters. Data collection was conducted in April at six locations in the north and the south eastern Luwu. Mechanical Underwater Visual Cencus (UVC) and transect method (Line intercept Transec, LIT) with SCUBA equipment used for research data collection. Total reef fish species collected as many as 366 species belonging to 31 families, consisting of 150 species of fish target (fish consumption), 10 species of indicator fish (indicator species), 206 types of major fissh. The most dominant indicator type of fish is Chaetodon octofasciatus, while the major dominant family Pomacentridae, Labridae, and Apogonidae. Diversity index values ranged from 2.145 to 3.408. Dominance index (C) is in the range of 0.056 to 0.298. The result is expected to be a reference literature as basic data for the management of reef fish, especially in the waters of eastern Luw
