摘      要：Mangrove ecosystems are sites with high biodiversity of benthic fauna, and fiddler crabs(genus Uca) are common benthic fauna in mangroves. The North Sulawesi in Indonesia has a good condition of mangrove while the information of the fiddler crabs is still limited. Manual samplings were conducted in wet, dry and transient seasons at a mangrove in Kema, North Sulawesi to investigate the species composition, density and distribution pattern of fiddler crabs. A total of 168 individuals, subjected to eight species of genus Uca crabs were collected at the mangrove, with U. triangularis having the highest abundance and U. annulipes having the lowest abundance.The densities of fiddle crabs were 27.56 ind./m2, 32.89 ind./m2and 14.22 ind./m2at the seaward, middle and landward zones, respectively, and the density was higher in dry and wet seasons than in transient season.
