- ABSTRACTThis study aims to determine the diversity of crabs in the mangrove ecosystems in Natuna waters, Riau Islands. The study was conducted on 23 October to 5 November 2014. The crabs were collected from eight research stations using random method, by putting a transect quadrant of 1 x 1 m2 on an area of 10 x 10 m2 area at each mangrove observation station. Results obtained 274 individuals, from 21 species, 11 genera and 8 families. Crabs of the family Sesarmidae most diverse with 8 specie: Clistocoeloma sp., Nanosesarma edamensis, Parasesarma leptosoma, Parasesarma sp1., Perisesarma cf. brevicristatum, Perisesarma semperi, Perisesarma sp1. and Sarmatium crassum. Based on quantitative analysis, the index value of diversity ranged from 0.932 – 2.028, with the highest value obtained at Cemaga Utara (St. NTNM02). The eveness index in the range of 0.579 - 0.881 with the highest eveness at Cemaga Selatan (St. NTNM01).
