Guadalupe's inhabit the Guadalupe River in Texas. They look sorta different in coloration than Northern LMB and don't grow as large. They are sometimes called spotted bass but I'm not sure that's correct.
A Guadalupe is a type of large perch with a greenish-color and a peculiar brow knot over its eyes. I've had the opportunity to catch and fry up these fish and they make fine table fare. They definitely can't be confused with a bass.
