Description: Data of infestation of the Black Sea shrimp Palaemon adspersus were obtained. In 2015 - 2016 years the number of shrimp ranged from 5 to 15 specimen per m2. 220 spec. of grass shrimp the size of 2.5 - 6 cm was investigated. Frequency of metacercariae Helicometra fasciata (Rudolphi, 1819) (Family Opecoelidae) in the P. adspersus was 3%, and Gynaecotyle adunca (Linton, 1905) (Family Microphallidae) - 23%. Metacercariae G. adunca prefer excretory system, and H. fasciata - blood system, but they can meet together in the pectoral muscles of the shrimp. Preference both metacercaria of based walking legs of the shrimp may indicate a competitive interspecific relations trematodes. In larger hosts, for example, in the crab Carcinus aestuarii absence of metacercaria G. adunca in pectoral muscles is caused, apparently, by the host immune barrier-stout tissues gills.
