Abstract :The intensive use of antibiotics in aquaculture has resulted in increased resistance among fish pathogens, and this situation has led researchers to investigate the antibacterial properties of natural resources. The present study focused on an essential oil isolated from the leaves of Eucalyptus camaldulensis as a potential antibacterial that could be used against Aeromonas caviae . Eighteen compounds were identified in the essential oil, representing 86.68 % of the total oil. The components were found to be p-cymene insert ignore into journalissuearticles values(20.09%);, β-phellandrene insert ignore into journalissuearticles values(18.61%);, α-phellandrene insert ignore into journalissuearticles values(7.50%);, α-terpineol insert ignore into journalissuearticles values(6.02%);, terpinen-4-ol insert ignore into journalissuearticles values(5.50%);, Crypton insert ignore into journalissuearticles values(5.36%);, spathulenol insert ignore into journalissuearticles values(4.26%);, linalool insert ignore into journalissuearticles values(3.56%);, 1,8-cineole insert ignore into journalissuearticles values(2.77%);, farnesol insert ignore into journalissuearticles values(2.31%);, Cumin aldehyde insert ignore into journalissuearticles values(2.13%);, limonen insert ignore into journalissuearticles values(2.12%);, α-thujene insert ignore into journalissuearticles values(1.94%);, fellendral insert ignore into journalissuearticles values(1.13%);, γ-terpinene insert ignore into journalissuearticles values(1.10%);, sabinene insert ignore into journalissuearticles values(0.97%);, α-pinene insert ignore into journalissuearticles values(0.68%); and α-terpinen insert ignore into journalissuearticles values(0.63%);. The antibacterial efficiency of essential oils against Aeromonas caviae was determined using Minimum Inhibitory Concentration insert ignore into journalissuearticles values(MIC); and Minimum Bactericidal Concentration insert ignore into journalissuearticles values(MBC); values, ranging from 200 µg/ml to 400 µg/ml respectively. Our findings revealed the potential of essential oils isolated from Eucalyptus insert ignore into journalissuearticles values( Eucalyptus camaldulensis ); as a natural antibacterial agent that could efficiently contribute to the control of Aeromonas caviae infection in fish.
