The Indonesian fish parasite fauna is evaluated from literature since 1840, 678 new parasite records, 621 parasite and 315 host species. New species descriptions, records and methods demonstrate a higher biodiversity than thought (different geno- for similar morphotypes). Most former records originate from commercial or cultured fish. The current knowledge in a host-parasite checklist enables risk evaluation for aquaculture and fishery industries. The knowledge of the local species phylogeny enables conclusions on worldwide zoogeography and is discussed with a parasite checklist from Hawaii.
