Duane C Chapman


Duane Chapman is a Supervisory Fish Biologist at the Columbia Environmental Research Center in Columbia, MO. Since 2002, he and his team have focused on the biology and control of bighead, silver, black, and grass carps and other invasive aquatic species. Present research focuses on improvement of capture and harvest methodologies including development the “Modified Unified Method” to remove very large quantities carp and further modification of the method to serve as an early detection or rapid response technique. His team investigates the use of eDNA to estimate abundance and detect spawning, and the use of early life history and spawning behavior of carp for the development of control techniques, and risk assessments. Additionally, his team is researching the biology of black carp, the newest, largest, and least understood of the invasive carps, assessing movements, habitat selections, sources, diets, and risk to native species. His research is global in focus, and integrates information and research from around the world to address invasive species problems in the United States.
