The purpose of this study was to determine the type and level of prevalence and intensity of ectoparasites that infect mud crabs (Scylla serrata) in Asahan district. The method of data collection was carried out by field observation methods carried out in the sea silos, Pematang Baru, and Sei Kepayang areas. The crab samples observed were live crabs, the number of mud crabs taken for the sample was 10% of each population. Furthermore, in the carapace, the type of parasite that attacks is Trichodina sp with a prevalence rate of 38%. This parasite infected 5 of the 13 samples. Then the types of parasites Carchesium sp and Poecilasmatidae each with a prevalence rate of 31% these two types of parasites infect 4 samples of crabs found at the foot of theroad, this type of parasite infects 4 out of 13 samples. Then the types of parasites Carchesium sp and Poecilasmatidae each with a prevalence rate of 31% these two types of parasites infect 4 samples of crabs found at the foot of theroad, this type of parasite infects 4 out of 13 samples. Then the types of parasites Carchesium sp and Poecilasmatidae sp each with a prevalence rate of 31% these two types of parasites infect 4 samples of crabs found at the foot of theroad, this type of parasite infects 4 out of 13 samples. The crabs that attack the sea silos are Octolasmis sp, Ichtyopthyrius multifilis, Trichodina sp, Zoothamnium sp. The parasites that attack the new ponds are Octolasmis sp, Carchesium sp, Zoothamnium sp, and the parasites that attack Sei Kepayang are Octolasmis sp, Carchesium sp, Poecilasmatidae sp, Trichodina sp. The intensity of the parasites found was classified as moderate but for the parasite Octolasmis sp.
