Here, 11, 14 and 17 infrapopulations of<jats:italic>Gyliauchen volubilis<\/jats:italic>(Trematoda: Digenea),<jats:italic>Procamallanus elatensis<\/jats:italic>(Nematoda) and<jats:italic>Sclerocollum rubrimaris<\/jats:italic>(Acanthocephala), respectively, were collected from the fish<jats:italic>Siganus rivulatus<\/jats:italic>(Siganidae) in the Red Sea, from a chronically polluted small bay at Sharm El-Sheikh, South Sinai, Egypt. Water and sediment samples from the bay, tissue samples (intestines, liver, and muscle) from each fish, and samples from each parasite were taken for heavy metal analyses of cadmium and lead. Cadmium concentrations in intestines, liver and muscle of non-infected and infected fishes were much lower than those of lead, and both metal concentrations decreased in the order: liver\u00a0&gt;\u00a0intestines\u00a0&gt;\u00a0muscle. Cadmium and lead concentrations in the tissues of fishes infected with<jats:italic>G. volubilis<\/jats:italic>or<jats:italic>P. elatensis<\/jats:italic>were slightly lower than those in non-infected ones, while in the tissues of fishes infected with<jats:italic>Sc. rubrimaris<\/jats:italic>, they were much lower. Low concentrations of cadmium and lead in<jats:italic>G. volubilis<\/jats:italic>and<jats:italic>P. elatensis<\/jats:italic>are associated with their limited ability or capacity to accumulate trace metals. Therefore, bioconcentration factors corresponding to these species were relatively low, and both are herein considered as weak bioindicators. By contrast, high concentrations of cadmium and lead in<jats:italic>S. rubrimaris<\/jats:italic>are associated with its high ability to accumulate trace metals. Of the present three host\u2013parasite systems, only the<jats:italic>Siganus rivulatus<\/jats:italic>\u2013<jats:italic>Sclerocollum rubrimaris<\/jats:italic>system seems to be promising for biomonitoring of metal pollution in the Red Sea.<\/jats:p>","DOI":"10.1051\/parasite\/2019014","type":"journal-article","created":{"date-parts":[[2019,3,6]],"date-time":"2019-03-06T09:59:33Z","timestamp":1551866373000},"page":"12","source":"Crossref","is-referenced-by-count":34,"title":["Environmental Parasitology: intestinal helminth parasites of the siganid fish<i>Siganus rivulatus<\/i>as bioindicators for trace metal pollution in the Red Sea"],"prefix":"10.1051","volume":"26","author":[{"given":"Zaki M.","family":"Al-Hasawi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2019,3,6]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"378","DOI":"10.1017\/S0022149X11000551","volume":"86","author":"Al-Jahdali","year":"2012","journal-title":"Journal of Helminthology"},{"key":"R2","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1051\/parasite\/2012193227","volume":"19","author":"Al-Jahdali","year":"2012","journal-title":"Parasite"},{"key":"R3","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1017\/S0022149X11000186","volume":"86","author":"Al-Jahdali","year":"2012","journal-title":"Journal of Helminthology"},{"key":"R4","doi-asserted-by":"crossref","first-page":"2024","DOI":"10.3844\/ajassp.2009.2024.2029","volume":"6","author":"Al-Khatani","year":"2009","journal-title":"American Journal of Applied Sciences"},{"key":"R5","doi-asserted-by":"crossref","first-page":"273","DOI":"10.14411\/fp.2013.031","volume":"60","author":"Amin","year":"2013","journal-title":"Folia Parasitologica"},{"key":"R6","first-page":"196","volume":"42","author":"Amini","year":"2013","journal-title":"Indian Journal of Geo-Marine Sciences"},{"key":"R7","doi-asserted-by":"crossref","first-page":"929","DOI":"10.1007\/s00436-006-0384-8","volume":"100","author":"Baru\u0161","year":"2007","journal-title":"Parasitology Research"},{"key":"R8","first-page":"117","volume":"2","author":"Bayoumy","year":"2008","journal-title":"Global Veterinaria"},{"key":"R9","first-page":"15","volume":"72C","author":"Buckley","year":"1992","journal-title":"Comparative Biochemistry and Physiology"},{"key":"R10","doi-asserted-by":"crossref","first-page":"352","DOI":"10.1007\/BF00213171","volume":"27","author":"Campbell","year":"1994","journal-title":"Archives of Environmental Contamination and Toxicology"},{"key":"R11","first-page":"149","volume":"22","author":"Canli","year":"1998","journal-title":"Turkish Journal of Zoology"},{"key":"R12","first-page":"451","volume":"25","author":"Dauvalter","year":"1998","journal-title":"Water Resources"},{"key":"R13","doi-asserted-by":"crossref","first-page":"101","DOI":"10.24039\/rnh2009321117","volume":"3","author":"De Buron","year":"2009","journal-title":"Neotropical Helminthology"},{"key":"R14","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1016\/j.meatsci.2006.03.012","volume":"74","author":"Demirezen","year":"2006","journal-title":"Meat Science"},{"key":"R15","doi-asserted-by":"crossref","first-page":"387","DOI":"10.1111\/j.1095-8649.1989.tb03321.x","volume":"34","author":"Diamant","year":"1989","journal-title":"Journal of Fish Biology"},{"key":"R16","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1007\/s10661-006-0987-7","volume":"118","author":"Dural","year":"2006","journal-title":"Environmental Monitoring and Assessment"},{"key":"R17","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1080\/00222937900770041","volume":"13","author":"Fusco","year":"1979","journal-title":"Journal of Natural History"},{"key":"R18","doi-asserted-by":"crossref","unstructured":"Goater TM, Goater CP, Esch GW. 2013.
