I have caught some monster white bass lately while trolling for crappie. Another fellow has caught similar fish and assumed they were hybrids because of the size. Those I got I assumed were whites because only one stripe went completely to the tail. I didn't look at the tooth patches.
Following is the official Texas identifiaction guide, and I still think what I caught were whites, but next time I'll look in their mouths.http://www.tpwd.state.tx.us/publication ... rams.phtml
