| Fish farming has suffered greatly in the last few years as a result of epizootic ulcerative syndrome (EUS). It has been discovered that several fish are afflicted with this widespread sickness. Fish with EUS experienced severe hematological abnormalities. At the 1% level of probability, the decline in leucocytes, hemoglobin content, and erythrocyte count was extremely significant. Additionally, the packed cell volume (PCV) percent-age value dropped. The current study found a trend of decline in the values of several chosen hematological markers in Channa punctatus. The decline was found to be caused by microcytic anemia, which was caused by EUS. EUS thus caused significant hematological changes in the fish under study, Channa punctatus.
Keywords: EUS, Channa punctatus, RBC, Hb, PCV, WBC.
