An infographic highlighting a study finding that black carp, which are an invasive fish species in North America, are now known to be established in the wild in parts of the Mississippi River basin. The infographic was created by the USGS. The USGS was one of the study’s co-authors and the research was led by Southern Illinois University.
Patrick Kroboth
Patrick is a Research Fish Biologist at the Columbia Environmental Research Center.
Patrick has been a fish biologist with the U.S. Geological Survey Columbia Environmental Research Center since 2017 with research emphasis on invasive fish species, specifically Black Carp, Bighead Carp, Grass Carp, and Silver Carp. This research includes development of methods to improve capture, early detection, and control, and study of habitat use and movement. His prior experience ranges across lotic and lentic aquatic ecosystems studying recreational and commercial fisheries, invasive species, and threatened and endangered species.
