Duane Chapman is a Fish Biologist at the Columbia Environmental Research Center.
From 2002 - 2021, Duane led a team have focused on the biology and control of bighead, silver, black, and grass carps and other invasive aquatic species. He is now working part time, completing writing projects, mentoring, and assisting in risk assessments and other partner collaborations. His research and that of his team has focused on improvement of capture, harvest, and early detection methodologies, use of eDNA to estimate abundance and detect spawning, the use of early life history and spawning behavior of carp for the development of control techniques, and risk assessments. His research is global in focus, and integrates information and research from around the world to address invasive species problems in the United States. As he moves toward anticipated full retirement in 2024, the team he led is now guided by Dr. Jesse Fischer.

Black Carp Biology, Assessment, and Control
Black Carp (Mylopharyngodon piceus) is the largest of the four non-indigenous carp species, reaching sizes well in excess of 100 pounds. CERC scientists, in cooperation with federal and state partners, are studying the biology, ecology, and behavior of black carp and developing tools to monitor, assess, and control this non-indigenous species.Early Life History of Bighead, Silver, Black, and Grass Carps
Grass, bighead, black, and silver carps spawn in turbulent rivers and their eggs develop and hatch while drifting downriver. The larvae also have a short period of developing in the drift, and then they must swim from the river and find appropriate low- or no-flow nursery areas. Rivers which are not long enough, turbulent enough, or without nursery areas in the correct locations are not likely to...Invasive Carp Species Section
Bighead carp (Hypophthalmichthys nobilis) and the closely related silver carp (Hypophthalmichthys molitrix) (together, the bigheaded carps) and black carp (Mylopharyngodon piceus) are rapidly expanding in numbers and distribution in the Mississippi and Missouri River basins.Tracking radio-tagged Asian Carp with Unmanned Aircraft System
The ability to track fish such as invasive Asian carp is critical in characterizing their habitat, use and movement, spawning locations, feeding habitats, overwinter refugia, and general movement patterns. We anticipate that a UAS-based approach for tracking fish that are radio-tagged will prove effective and used widely. - Data
