Fish and Aquatic Organism Health
Fish disease research focuses on developing new techniques for detection and identification of emerging pathogens and other causative agents, linkages between disease resistance, virulence, and immunology, and the role of environmental stress on disease outbreaks and severity. USGS research investigates pathogens and other environmental factors that affect aquatic organism health to support the management, conservation, and restoration of aquatic species. Fish disease research includes both basic and applied science focused on understanding the factors that control the distribution and severity of infectious diseases affecting aquatic organisms and populations.
