ABSTRACT Research on the intensity and prevalence of ectoparasites in mangrove crabs (scyllaserrata) has been conducted in the brackish waters of Cadek Village, Baitussalam District, Aceh Besar in November to December 2020. The purpose of this study was to determine the types of ectoparasites, their prevalence and intensity in mangrove crabs (Scylla serrata) in Cadek Village, Baitussalam District, Aceh Besar District. Samples were taken randomly and the data were analyzed descriptively in the form of tables and figures. The results showed that 1) The types of ectoparasites infecting mangrove crabs in the brackish waters of Cadek Village were Octolasmis and Zootahmnium sp. 2) The prevalence value of the ectoparasite species infested with Scylla serrata in the brackish waters of Cadek Village is Zoothamnium sp. 40% and Octolasmis sp. 90% who fall into this category of parasites almost always infest Scylla serrata. 3) The intensity value of the ectoparasite species infested with Scylla serrata in the brackish waters of Cadek Village was Zoothamnium sp. 6.75 parasites / head and Octolasmis sp. 69 parasites / fish included in the very heavy infestation category.
