Developing Tools to Manage Bighead Carp

Terrance D. Hubert, PhD, USGS Upper Midwest Environmental Sciences Center 

Synopsis:  Multiple investigations are developing tools for the management of invasive bigheaded carps (Bighead Carp Hypophthalmichthys nobilis and Silver Carp H. molitrix) that are spreading through the Mississippi River basin and threatening to invade others.  This presentation will provide an overview of the molecular surveillance methods USGS is developing, in collaboration with partners, to track and monitor populations of bigheaded carps and identify the limits of the range expansion.  The presentation will also discuss the development of potential physical and chemical controls intended to limit or reduce populations of bigheaded carps.  Results of laboratory and field investigations of eDNA surveillance tools and physical and chemical control tools will be presented and discussed.


Speaker Bios:   Terrance D. Hubert received a bachelor’s degree in chemistry from Ripon College in 1980.  From there he attended the University of Iowa where he studied naturally-occurring plant protective chemicals en route to earning a PhD in organic chemistry in 1985.  Following a one-year postdoctoral term in the Department of Chemistry at the University of Missouri, Dr. Hubert joined the staff of Hazleton Laboratories America where he conducted research on the metabolism of agricultural pesticides in support of registrations of these chemicals with the Environmental Protection Agency.  He entered into federal service in October of 1992 when he was hired at the Upper Midwest Environmental Sciences Center, U.S. Geological Survey, in LaCrosse, Wisconsin, to conduct studies to support the registration of fishery management chemicals, most notably the chemicals used control the invasive sea lamprey in the Great Lakes basin.  For the past six years, Dr. Hubert has also been actively engaged in bighead and silver carp control research, particularly in the efforts to develop methods of selectively delivering toxicants to the invasive fish.
