How these southern striped bass spend their days, especially related to spawning, became much clearer thanks to research conducted by fish biologist Jason Marsik with the South Carolina Department of Natural Resources (SCDNR) and his colleague, Dr. Jason Doll at Francis Marion University. Using Sport Fish Restoration dollars derived from federal excise taxes paid by the manufacturers of fishing tackle and a portion of the federal gas tax that is attributable to motorboats and small engines, the two sought to better understand striper habitat use and movements in the Great Pee Dee River, particularly at spawning time.
