Biography
BJ Schall is a fisheries research biologist currently working for the South Dakota Department of Game, Fish and Parks. BJ received his B.S. from South Dakota State University, and his M.S. from the University of Nebraska at Kearney. He spent nearly three years working as an invasive species biologist and has been in his current role since 2020. Much of BJ's past research has been focused on fish population dynamics. As part of the South Dakota Cooperative Fish and Wildlife Research Unit, BJ will be working a project using retrospective analysis to evaluate the effects of extreme flood events during 2019 on the fish communities, with an emphasis on a native (Blue Sucker), invasive (Silver Carp), and two sportfish (Channel Catfish and Flathead Catfish) species.
