Dr. Kevan Main

Senior Scientist Emeritus

Emeritus Senior Scientists

Today's Research for Tomorrow's Oceans



Dr. Kevan Main has led Mote’s aquaculture research programs since 2001. Before becoming a Mote Senior Scientist Emeritus in 2022, she served as Director of Mote’s 200-acre field station, Mote Aquaculture Research Park, in eastern Sarasota County. Dr. Main served as the Mote Eminent Scholar Chair in Fisheries and Aquaculture from 2013 through 2016. In 2012, Dr. Main was served as the President of the World Aquaculture Society. Her research interests are in developing sustainable aquaculture methods to produce marine fish, sturgeon, shrimp, abalone, and corals through aquaculture. Dr. Main received her Ph.D. from Florida State University and has more than 35 years of experience in the aquaculture of tropical and subtropical fish and invertebrates from around the world. She has published seven books and more than 98 peer-reviewed publications and has traveled to aquaculture facilities throughout Asia, Europe and the United States. In 2016, Dr. Main was recognized as a “White House Champion of Change for Sustainable Seafood.”
