Aquatic animal health professionals diagnose, prevent and treat diseases, injuries and dysfunctions of aquatic animals by implementing appropriate sampling protocols. They supervise the use of medicines, including vaccines, and collect data on fish health, making regular reports to the appropriate personnel. They may provide care to a wide range of aquatic animals or specialise in the treatment of a particular group or in a particular speciality area. They may provide advice, support and training to farm staff on best practice with regard to the health and welfare of the cultured organisms.
