Mangrove crabs ( Scylla tranquebarica ) are one of the fisheries commodities with high economic value. However, there are several obstacles in the process of developing crab culture, such as parasitic infections. The presence of parasites can reduce production in crab culture, one of which is the parasite Octolasmis sp. The purpose of this study was to identify Octolasmis parasites that infect mangrove crabs and knowing the prevalence rate of the parasite Octolasmis sp. on mangrove crabs in Lubuk Kertang, Langkat. This research used exploratory method, while the sampling technique used in sampling was the random sampling method. Crab identified as many as 15 crabs. The results showed that the type Octolasmis sp. identified to attack mangrove crabs in Lubuk Kertang, Langkat are Octolasmis cor and Octolasmis angulata . The prevalence rate of the Octolasmis parasite was based on the number of parasites found, the Octolasmis cor parasite is 93.3% and the number of O. angulata is 53.3%. Based on the prevalence and intensity of octolasmis found more octolasmis cor than octolasmis angulata .
