The potential of freshwater farming in the Special Region of Yogyakarta is very high. Infectious and non-infectious diseases can cause significant economic losses. The main problem of infectious disease is caused by viruses, bacteria, fungi and parasites. This study was conducted to identify diseases that attack freshwater fish using data analysis on fish disease cases in the Laboratory of Pathology, Faculty of Veterinary Medicine, UGM in 2019. A total of 239 cases of fish diseases were examined by the Laboratory Diagnostic Co-assistance students in 2019 from the Special Region of Yogyakarta which includes Sleman district, Kulonprogo district, Yogyakarta City, Bantul district and Gunungkidul district. Based on data analysis, it showed that the highest fish sample was tilapia (52%), came from Sleman Regency (94%). The highest disease infection was caused by bacterial infections (54%) followed by parasite infections (35%). Macroscopic changes were observed in the liver (25%), skin (19%). and gills (26%). These changes included a yellow swollen liver, ulcer in the skin, fragile consistency and nodules in the surface of kidneys, attachment lamella and necrosis of gill lamellas. The parasite identification resulted in following parasite taxa/species Dactylogyrus., Trichodina sp., Gyrodactylus sp. and Ichtyopthirius sp. in the Parasitology Laboratory. The histopathological changes were identified using the the Hematoxillin & Eosin st aining technique, the organs showed dermatitis (18%), hepatitis (27%) and branchitis (23%). It can be concluded that in this research the highest cases of freshwater fish disease in Yogyakarta Special Region were caused by bacterial infections of tilapia from the Sleman district.
