Popis: Despite being an important component of the marine ecosystem and posing health risks to human seafood consumers, fish parasites in Indonesia have yet to be adequately described. Here, we analyzed the diet and metazoan parasite fauna of seven commercial fish species (Alectis indica,Carangoides chrysophrys,Johnius borneensis,Mene maculata,Trichiurus lepturus,Upeneus asymmetricus,U. moluccensis) landed in Java, Indonesia. We isolated 11 endoparasite species, established 22 new host and 14 new locality records, and extended parasitological records ofA. indicaby 24%,C. chrysophrysby 25%,J. borneensisby 40%,M. maculataby 44%,U. asymmetricusby 100%, andU. moluccensisby 17%. We genetically identified the trematodeStephanostomumcf.uku(of Bray et al. 2005) fromAlecta indicafor the first time in Indonesia and provided the sequence of its 28S marker. Stomach content analysis revealed seven different prey items, and the examined fish species were grouped into four feeding categories, which differed significantly in their respective endoparasite fauna. All but two examined fish species hosted potentially zoonotic nematodes, which reveal a risk for parasite-borne diseases in Indonesian food fishes and call for more consequent monitoring with regard to seafood safety in this region. With this study, we were able to establish an association between the feeding ecology and the endoparasite fauna of marine fishes which will help to better understand the transmission pathways of (potentially zoonotic) parasites in food fishes in tropical waters.
