The aim of this study is detecting the prevalence of infection with Sarcotaces sp. (copepods), which infest some marine fish species at the Eastern province of Saudi Arabia, as well as recording the clinical sings and post mortem lesions, seasonal variation of the infestation and detecting the relation between size of the infected fish and prevalence of sarcotaces infestation. At different times between Marsh, 2012 and February, 2013, a total of 660 fish belonging to 18 species freshly collected from Arabian Gulf, Qatef, Eastern Province of Saudi Arabia, for routine examination. About 6 fish only infested with Sarcotaces. Eighteen fish species were examined only one species; Epinephelus chlorostigma, infested with sarcotaces with prevalence percentage 6.74%. Fish infected with Sarcotaces sp. showed no any clinical abnormalities and appeared to be completely normal. Epinephelus chlorostigma infected with Sarcotaces sp. had cysts, pyriform in shape, gray in color in the flank muscles near to the anal vent. The cysts appeared only when fish are filleted and cut cysts release copious black fluid over fillets. Sarcotaces infest only old and large fishes. Prevalence of sarcotaces was higher in warm seasons, summer and spring with prevalence17.85% and 3.84% respectively. Scan Electron Microscope (SEM) was carried out for isolated Sarcotaces and cysts, also histopathological examination for musculature of infected fish were carried out. A new host and geographical record for Sarcotaces is presented, being this first record of Sarcotaces sp. in the Arabian Gulf.
