Based on data from KKP, Indonesia recorded the value of crab meat exports in

Attacks from ectoparasites can cause harm organs in the host organism, among others, damage to the body surface and  the gills of the host. This study aims to find out identification, intensity and prevalence of ectoparasites found in crab in Margasari Village Waters, Labuhan Maringgai District, East Lampung Regency. This study includes taking 40 crab samples obtained from the catch of fishermen from two stations, Panceran and Gambas stations. The data of ectoparasite samples found from the examination results are then recorded and for ectoparasite attacks on crab can be analyzed by counting prevalence and intensity. Crab ectoparasites identified in the Margasari village, Labuhan Maringgai, East Lampung Regency, among others Octolasmis sp., Chelonibia sp., and Thompsonia sp.
