This study explains about prospects in relation to current and future treatments for fish diseases. Currently, outbreaks of parasite and bacterial diseases have acted as an important limiting factor for fish farming. So producers have made use of massive amounts of chemicals and antibiotics to control mortalities and avoid economic losses. The therapy of fish diseases is not well regarded due to the side effects of the products available for use today, thus, studies of safer and more effective alternative treatments are needed. The use of herbal medicines in animals has shown promising to be a natural, biodegradable and have antimicrobial activity against many pathogens, including fish. In in vitro and in vivo experiments, we evaluated the potential of three herbal medicines against an important pathogen of fish, Ichthyophthirius multifiliis. Essential oils of Melaleuca alternifolia, Lavandula angustifolia and Mentha piperita, showed in vitro activity against I. multifiliis. Treatment with the essential oil of M. alternifolia in water was effective against the disease caused by this parasite. These three herbal oils showed potential as replacements to current treatments used to control of this important parasitic disease in fish
