The objective of this study is to determine the prevalence and intensity of Trichodina sp. in Nile tilapia (Oreochromis sp.) fry, as well as to morphologically identify the species of Trichodina sp. Nile tilapia fry specimens measuring 1.5-3 cm were obtained from the Freshwater Fish Seed Centre (Balai Benih Ikan Air Tawar = BBIAT) in Muntilan, Magelang Regency. Morphological identification was conducted by quantifying the diameter of the adhesive disc, diameter of the denticulate ring, and the number of denticles. The results indicated that the prevalence of Trichodina sp. in Nile tilapia fry at BBIAT Muntilan was observed in all samples (100%), with a density of 130.15 individuals per fish. The identified species include T. heterodentata, T. mutabilis, and T. centrostrigeata, as well as unidentified species of Trichodina sp.
