Aquatic and fisheries science is the study of aquatic ecosystems to increase scientific understanding and to apply basic ecological principles to their management, thereby sustaining them for multiple uses. Aquatic ecosystems include wetlands, streams, lakes, estuaries and oceans. Aquatic science professionals study and manage valued natural systems for seafoods, drinking water, recreation, transportation and aesthetics. This field of study has a long history; for example, the American Fisheries Society was founded in and the American Society of Limnology and Oceanography in Aquatic systems and their organisms are sufficiently distinct from terrestrial systems that numerous professional organizations and scientific journals have been founded specifically to foster communication among aquatic science professionals. Dence conducted pioneering studies on aquatic systems in New York in the early s. The present aquatic program at ESF builds on that early tradition with a wide array of aquatic courses.
