This study was conducted to determine and compare the antimicrobial property of the epidermal mucus of Tilapia (Oreochromis spp.) from two environmental conditions, the fish tank and fishpond. The antimicrobial property was determined using Filter Paper Disc Diffusion Method with Amoxicillin and Nystatin as the positive controls and distilled water as the negative control. Results showed significant differences in the effects of the treatments when tested against Escherichia coli, Staphylococcus aureus, Bacillus cereus, Bacillus subtilis, Bacillus megaterium, Pseudomonas aeruginosa, Candida albicans, Aspergillus niger and Aspergillus flavus (p<0.05). The Duncan’s Multiple Range Test further proved that the mucus of Tilapia from fishpond was significantly higher in terms of antibacterial property compared to mucus of Tilapia from fish tank. On the other hand, both of the epidermal mucus of Tilapia from fishpond and fish tank did not show any inhibitory effect against P. aeruginosa and A. niger. The epidermal mucus of Tilapia showed bacteriostatic, fungistatic and bactericidal effects against test microorganisms. Based on the results, the mucus of Oreochromis spp. from fishpond and fish tank are potential sources of antimicrobial compounds.
