The extensive use of antibiotics and various chemical compounds has resulted in drug residue and resistant pathogens in treated fish. Drug residue not only pollutes the environment, but also threatens human consumers. In contrast, garlic as a well‐known natural antibiotic that causes no environmental or physical side effects has shown to be effective for the treatment of many diseases in humans and animals owing to its antimicrobial, antioxidant, and antihypertensive properties. In aquacultural operations, garlic with dose optimization is strongly recommended. This review focuses on the application of garlic in various fish diseases treatments and the prospects of using garlic preparations in aquaculture.
