Doc got your point, such terms as perch, bluegill, sunfish are interchanged to describe the same fish, but I always thought brim was a generic term and not a species of sunfish. Then again Bass are a type of sunfish....and walleye are a perch so when my daughter is catching sunfish and calls it perch jerking it always gets on my nerves. I have hooked some 1- 2lb bluegill on beaver but always on a drop shot or jig, but then could have been red ear since I don't look at panfish that close but sure were not any type of perch....
