A total of 50 specimens of marine fish Siganus rivulatus were investigated for internal protozoa. The fish samples collected from two positions: EL-Sigalaa and Dungunab bay. The samples were taken from blood (from tail area) also from liver, kidney and gonad. The study revealed Haemogregarina sp. from blood, and Myxobolus sp. and Henneguya sp. recovered from Liver, kidney and gonad. Also the study revealed Cryptobia sp. from Liver of Siganus rivulatus. The parasite prevalence in EL-Sigalaa is 56% while that for Dungunab bay is 38%. Also the density of parasite is higher in EL- Sigalaa than that of Dungunab bay.The Gonads had higher density (78%) in both location and most of the parasite identified is Myxobolus sp.
