Background: Aeromonas species is one of the most important causes of diseases in Clarias gariepinus, a public health threat with significant economic losses. Objectives: In this research, the prevalence and variety of Aeromonas species isolated from C. gariepinus cultured in an earthen pond were investigated, as well as the antibiogram and multiple antibiotic resistance indexMethods: Aeromonas species were isolated by culture and biochemical test and confirmed using a Microbact 24E kit. The antibiotic susceptibility to 10 antibiotics was determined using the Kirby-Bauer disk diffusion method.Results: Aeromonas species were isolated with a prevalence of 43.1% with 4 different phenospecies with the highest prevalence of 46(24 %) for Aeromonas hydrophila followed by 15(7.8%) for Aeromonas caviae, then 10(5.2%) for Aeromonas veronii sobria, and the least was observed for Aeromonas veronii veronii 6(3.1%). The Aeromonas species showed high resistance to amoxicillin, ampicillin, colistin sulfate, oxytetracycline, trimethoprim/sulfamethoxazole, and penicillin, with varying resistant patterns, and the multiple antibiotic resistance index values ranged between 0.20 and 0.80. Conclusion: There was a diversity of Aeromonas species associated with multiple antibiotic-resistant leading to the wide spread of antimicrobial resistance. Therefore, there is a need to control the use of antibiotics and ensure the effective use of biosecurity and preventive management measures in fish farms.
