 | | The old dogma regarding gizzard shad (and threadfin shad for that matter) was based on an expectation of severe competition for food between shad and sport fish species, primarily with bluegill. |
 | | Therefore, gizÂzard and threadfin shad, being filter feeders, would out compete bluegill for food, causing a decline in the bluegill population, both in number and quality, and a corresponding decline in the bass population. |
 | | The gizzard shad populations in the research ponds were, on average, nearly 600 pounds per acre. |
