Biologists recently stocked 37,000 threadfin shad into Greers Ferry in an effort to reestablish this vital forage species. Crappie, bass and hybrid stripers all have shown poor condition in the last year, primarily because of a lack of forage species. Upon investigation, the threadfin shad population in the lake was completely gone. Stockings of all predator fish have been suspended, and all stockings will focus on minnows, shad, bream and other prey species until the forage base can support the predator fish already swimming in the lake.
