Abstract

  Ethiopia has large water resources with estimated surface area of 733 km² of major Lakes and dams, 275 km² of small water bodies and 7,285 km long rivers within the country. The country has home of highly diversified flora and fauna. More than 200 species of fish are present in lakes, rivers and dams of Ethiopia. A cross sectional study was conducted from November 2017 to April 2018 in Sebeta National Fishery and Other Aquatic Life Research Center, central Ethiopia to study clinical sign, prevalence and risk factors of in Trichodiniasis in fish. 384 Live fish were collected randomly after the fish were collected by fisher man using fish net. Wet smear technique was conducted from gill tissue biopsy and skin scraping. The diseased fish had signs of dullness, detachment of scales, excessive mucus accumulation, ulcerations, congested fin base and pale gill. Out of 384 fish, 233 (60.7%) were found to be positive for trichodiniasis. Analysis of possible risk factors has shown that, there was statistically significant association (P < 0.05) between prevalence of disease and sex, parasites infestation, examined organs, body weight and total body length. However, the difference was not statistically significant (P > 0.05) between disease occurrence with species and pond number in area. In conclusion, the present finding has demonstrated that trichodiniasis is one of the important parasites of fish in the study area. Therefore, further epidemiological investigations are required to determine the trichodina species and different risk factor on the occurrence of the disease.
