Summary, Etc. Note: |
Abstract: Gizzard shad and threadfin shad reamins in predator stomachs can be specifically identified by differences in their gizzard dimensions. A separation line equidistant from the gizzard length-width means of the two species of standard deviations is presented, as well as a regression of total fish length on gizzard width. Fairly reliable identification is possible when gizzard widths are greater than 4 millimeters. |
