The threadfin shad is considered by most fishery managers to be the single most important prey fish in South Carolina’s reservoirs. Although the threadfin shad occurs in all but the coldest of the state’s waters, they are most productive in large impoundments. In these impoundments, the shad rarely lives past one year, and during that time it grows no more than three or four inches in length. This makes it an ideal sized food item for all advanced predators.
