O.K. I see 3 different species of pickerel.
Grass
Redfin
Chain
But searching fishbase, they have the same information for both the grass and redfin pickerels. Even the same picture. Another place said grass pickerel don't get larger than 9" while redfin are supposed to reach 15.5 inches, while chain pickerel could reach up to 30".
But, with any of the pickerels, where to source them for a pond? How well would they do in a pond with any typd of Bass, given their fusiform shape?
I always thought a chain pickerel x musky hybrid would be sportfish that might work for more southern waters.
