The KY Dept of Fish & Wildlife Resources (Dept of Fisheries) put out a booklet (reprint) in 1999 that shows the major fishes of the state. Color pics & descriptions, distribution areas, nicknames, etc. is contained in the booklet.

It shows a Longear Sunfish as being "Also called" a "bream", "sun granny", "sunperch", "creek perch", and (oddly enough) a "PUMPKINSEED" ..... YET, in the Description section it plainly says "This fish should not be confused with the Pumpkinseed (pictured on pg32)".

When you get into the "nickname" game, when trying to identify Sunfish species, you're gonna find yourself understanding why so many people just call them all "Brim"
