Parasitological examination of 150 young-of-the-year roach (Rutilus rutilus) during winter 2001/2002 in northeast Germany revealed the presence of larval Philometra obturans and Neoergasilus japonicus. This is the first record of roach as a paratenic host for P. obturans, and both records are the first for Germany. There is evidence that P. obturans has been overlooked in previous studies, whereas N. japonicus appears to be a neozoan species originating from Eastern Asia.
KEY WORDS: Philometra obturans, Nematoda, Neoergasilus japonicus, Copepoda, roach, Germany
