Parasitic fauna of the marine greater lizard fish Saurida undosquamis (Richardson, 1848)

Through examination of 125 specimens of the marine greater lizard fish Saurida undosquamis (Richardson, 1848) obtained from Zagazig fish market and its source from Gulf of Suez, the overall prevalence was 44.8%. The parasitic fauna was composed of Acanthocephala; Serrasentis sagittifer (prevalence: 12.8%), Cestoda; Oncodiscus sauridae (prevalence: 5.6%), Nematoda; Echinocephalus species larvae (prevalence: 4%), female of Philometra species (prevalence: 13.6%) and Trematoda; Lecithochirium grandiporum (prevalence: 16%) and juvenile didymozoid; Neotorticaecum (prevalence: 2.4%). The most prevalent parasitic fauna was nematodes followed by trematodes then acanthocephala and cestodes. The detected parasitic fauna was morphologically described by light microscope.
