Gizzard Shad are planktivores, straining minute organic particles with their gill rakers into their pharyngeal organ which is thought to concentrate and process food for swallowing. As you travel to more northern latitudes, gizzard shad, due to temperature range and colder lake temperatures, will frequently occupy more shallow depths than they would in the South. and the Texas Department of State Health Services.

Names and dates are hyperlinked to their relevant specimen records. [9] As zooplankton are a nutritionally superior food than detritus, if large zooplankton (e.g., Daphnia) are available, gizzard shad probably prefer to feed on this resource. Origin and dispersal of the alewife, Alosa pseudoharengus, and the gizzard shad, Dorosoma cepedianum, in the Great Lakes. American Fisheries Society, Bethesda, MD.
