| Outline of Final Research Achievements |
A bibliographical survey was made concerning host-parasite relationships between fish and cymothoid isopods from Japan. Thirty-five species of cymothoid isopods parasitic on fish have been recognized. I proposed the standard Japanese name for 3 genera and 9 species that had no standard Japanese name so far, and changed the standard Japanese name for the 6 species. Elthusa moritakii sp. nov., a branchial parasite of the deepwater bullhead sculpin Ereunias grallator, is described from Japan. In addition, new host records of Elthusa propinqua were reported. We also report on the morphology and ecology of juveniles.
