That is crazy that generations of people in ontario will grow up not knowing the difference between a pickerel and a walleye! If someone from your area Dono catches a pickerel do they call it a pickerel too or is it just that they haven't ever seen a pickerel to know the difference?

How does a section of the US start calling a sunfish a perch?

I find it fascinating that everything in the south is a 'bream' I wonder how far north you get before the bream name drops away and they are called sunfish again?

Sunfish, warmouth, and rock bass are all very different, I wonder why their names are intertwined/confused with each other?
