You caught a White Perch, not a Silver Bass
Here is a technical comparison:
White Bass
COMMON NAMES: White bass, Silver bass
SCIENTIFIC NAME: Morone chrysops
IDENTIFICATION: White bass are silvery in color and have a milky white belly. In addition, they have six or more dark lateral lines on the sides and back. This fish has two dorsal fins with the first having nine spines. The white bass closely resembles the hybrid striped bass and the white perch.
White Perch (Your mystery fish)
COMMON NAMES: White perch, Silver perch, Gray perch, Blue nose perch
SCIENTIFIC NAME: Morone americana
IDENTIFICATION: The white perch is a deep bodied fish that looks very similar to the white bass. The main difference is that the white perch is all silver and does not have dark lines running the length of the body.
Hope that helps! I know it's nice to know what you have caught
