first the MNR referred to them as yellow pickeral and knew that chain pickerel were different species , so the "no thats walleye not a chain pickerel" does not hold water
only because they made an agreement with the US the mnr now refer to them as walleye
hell the US doesn't even have a firm handle on English ask them to spell harbour or neighbour next the argument will be do we call it a sofa or couch or chesterfield
everyone knows what each name means so just except it and move on
