The aim of the study is survey of internal protozoan of one species of fish at White Nile (Sudan). A total of 1200 samples from 300 specimens of Oreochromis niloticus were investigated for internal protozoa. The fish samples collected in the period from (October, 2013 to March, 2014) from three positions: Kosti, Jabal Awalia and Khartoum. The (1200) samples were taken from Blood (from tail area), Liver, Kidney and Gonads. The study revealed Trypanosoma sp. from Blood, also Myxobolus sp., Myxosporea sp. and Cryptobia sp. recovered from Liver, Kidney and Gonad of Oreochromis niloticus. The total infected samples (from Blood, Liver, Kidney and Gonads) in Kosti are 164 samples, in Jabal Awalia are (119 samples) and in Khartoum are 157samples and generally the total infected samples from the White Nile Sudan are 440 samples in total of 1200 samples.  The prevalence of protozoan parasite in Kosti is 85% in total while that for Jabal Awalia is 70% in total and in Khartoum is 85%. Also the density of protozoan parasite is highest in Kosti. The Kidney have the highest density (60%) and most of the parasite is Cryptobia.

Key Word: Survey, Parasites, Internal Protozoa, Oreochromis niloticus.
