Nutrition impacts every life stage of an animal. Failure to provide optimal nutrition can directly result in disease outbreaks or in a weakened immune system that can predispose fish to disease. Organisms known to cause disease in fish include bacteria, fungi, viruses, and various kinds of parasites. Nonliving agents that adversely affect fish health may originate from inside or outside the fish. This book is one of the few books to provide comprehensive information on nutrition as a means to improve fish health and defend against infection. Providing a comprehensive overview of the subject, the book equips aquatic animal health professionals with all the information needed to competently and effectively treat these patients, from transporting and examining fish to diagnostic techniques and the identification and treatment of specific diseases and syndromes.
