Threadfin shad gizzard weights were used to determine the total length and total weight of threadfin shad. It was found that a high degree of correlation existed among the parameters tested and that the best relationship was between body weight to gizzard weight empty. Using this information it is possible to estimate the weights of threadfin shad eaten by predatory fish.
