Hematology is an indicator effectively and sensitively used to monitor the physiological and pathological changes in fish. A. acuminata is a traditional terrestrial plant from eastern Mallucas, Indonesia, used to cure hepatitis, diarrhea, and malaria. This fact indicates that this plant contains chemical compounds as anti-bacterial and immuno-stimulant being able to control diseases, particularly in fish.
