Welcome to the Fish Health Section of the American Fisheries Society

The Fish Health Section (FHS) is one of the largest and most international sections of the American Fisheries Society. The FHS was formed in 1972 to give fish biologists, diagnosticians, researchers, aquaculturists, veterinarians, administrators, and others involved in fish health, an organization for communication and interaction.
