Definition of wiper (Entry 2 of 2)

: a hybrid striped bass that is a cross between a female striped bass (Morone saxatilis) and a male white bass (Morone chrysops) and is silvery-white with dark usually discontinuous or irregular horizontal stripes along the sides

Note: The wiper has an aggressive nature and is bred chiefly as a sport fish for stocking lakes, streams, and reservoirs.

White bass and striped bass have solid stripes on their bodies. The hybrid fish, also called wipers or whiterock bass, have broken horizontal stripes, grow larger than white bass and are more tolerant of warm water than stripers.— D'Arcy Egan While wipers are far from unpalatable, their flesh is of a coarser texture and tastes a little more "fishy" than crappie or walleye fillets.— Steve Davis

called also palmetto bass, whiterock bass

— compare sunshine bass
