If someone's fishing Sooner, Kaw, Keystone or downstream,  this may help anglers return the small white bass to grow up and immediately kill the invasive white perch. The white perch are by the way,  delicious when big enough to filet
Kurk, I got this off google so please check for accuracy.  If it has lines or stripes it is a white bass(very small stripers and hybrids will have lines, stripes or broken stripes, too).  If one pulls  the top sticky dorsal fin erect, and the soft dorsal fin right behind it is relaxed,  it's a white bass OR if holding the top spiny dorsal fin erect makes the soft dorsal fin right behind it erect, it's a white perch.  Also note the differences below in the anal fin. White perch are egg eaters and not indigenous or welcome in this state and classified as an invasive species.



is it a white bass (aka sand bass, sandie) or a white perch?

WHITE BASS (Morone chrysops)

  • The body is deepest below the dorsal fin and the depth remains fairly uniform below the entire spin dorsal fin.
  • From 6 to 10 dark lines run horizontally down the back and sides.
  • When the spiny dorsal fin is pulled erect, the soft dorsal fin remains relaxed.
  • Each of 3 bony anal fin spines are of different lengths and are arranged in ascending order.
  • The anal fin usually has I I or 12 soft rays behind the 3 bony spines.

WHITE PERCH (Morone americana)

  • The body is deepest just ahead of, or at the beginning of, the dorsal fin.
  • There are no lines or stripes on the back or sides.
  • When the spiny dorsal fin is pulled erect, the soft dorsal fin also becomes erect.
  • The second and third bony anal spines are almost exactly the same length.
  • The anal fin usually has 8 or 9 soft rays behind the 3 bony spines.
