There is a
white bass Morone chrysops and a
yellow bass Morone mississippiensis.
They are part of the temperate bass family, the Percichthyidae family. Collectively known as sea bass. This family has its roots in the ocean and through geologic changes, the white and yellow bass were land locked. The closely related
striped bass Morone saxatilis which is still an ocean fish except where it has been stocked into landlocked reservoirs. Of course there is our beloved
HSB hybrid(Iowa DNR goofed up describing the cross, ooops). There is also the
white perch Morone americana which is actually a temperate bass and is closely related to the other 3 species. Striped bass can actually be successfully crossed with yellow bass and white perch. However, the white bass X striped bass cross has become the most popular. White perch have now found their way into many Midwestern BOW's and from what I understand have greatly affected walleye populations through predation on their eggs and fry.
There are also several other purely saltwater sea bass from the same family...
