Aeromonas hydrophila is the most common bacteria that causes mortality among fish.
But the antibiotics used to treat the fish is limited, expensive and have bad side effects
to fish. In this experiment, Aloe vera extract was used to substitute antibiotics. The
objective of this experiment is to investigate the healing effect of Aloe vera extract to
heal the infected fish and to know the best concentration of extraction from Aloe vera
that helps heal the infected fish. The experiment was conducted by using 120 tilapia
fish immersed in 10 7 CFU/ml Aeromonas hydrophila. A diet was prepared with different
concentration of Aloe vera gel extract which is 0%, 25%, 50% and 100%. In the
present experiment, it shows that the best concentration to heal the fish is 100%
concentration as the least number of dead fish recorded. The best concentration in
descending order are 100%, 25%, 50% and 0%.
