Abstract

Historically, the gizzard shad's, Dorosoma cepedianum (Le Seuer), role in the management of warm-water sport fisheries has evolved amid considerable controversy. Initially recognized as potential forage for piscivorous species in suitable waters (e.g. see Lagler and Applegate 1943 and Eschmeyer 1944), this species is currently maligned because of its "probable" competitive effects on desirable species (e.g. see Jenkins 1957), suggested no doubt by its great capacity for attaining and maintaining populations of mass proportions. Prevailing management practices in most areas call for its control if not its elimination (e.g. see Bowers 1955). It is interesting to note that evidence has recently been presented to the effect that under certain conditions at least, the shad's forage potential may be reflected in increased production of desirable species (Schneidermeyer and Lewis 1956).
