Juvenile chain pickerel

The jury is still out. BTW "redfins" are not a good distinguishing characteristic on redfin pickerel. Unless they come from Dustin.
It could just be that there is a certain amount of proportional range amongst individuals. The first time I saw it in October, I was skeptical that it was a redfin. I had never seen a redfin in person before (at that time), but I thought they were supposed to look more like grass pickerels than does this fish. Also, its fins are not red. But Matt insisted it was a redfin, so I took his word, since he has more experience. When you saw it that day in December, Brian, and said it was not a redfin, but a chain, I felt vindicated.
(Just kidding. I wanted to use that smilie!)
I still say it looks EXACTLY like the pictures of a chain pickerel from NatureServe Explorer. That's my story and I'm sticking to it. It is a chain pickerel.
I think, in the end, though, only Matt will resolve the debate by updating us several months from now as the fish grows (or doesn't grow, as the case may be).
Seeing those pictures of juvenile chain pickerels has been quite informative. Thanks, guys!

Interspecific differences in ontogentic development of the color patterns (Crossman 1962a, 1966) are inconsistent in Virginia fish. Often the side of large young and small juvenile redfin pickerel is distinctly barred, blotched, or both, resembling small chain pickerel. Some of the atypical fish may be hybrids
both quotes from Freshwater Fishes of VA, p. 240
Hybridization causes problems of identification in southeastern Virginia.
This fish was collected in the eastern portion of VA.

Branchiostegal ray count = 13
Submandibular pores = 4
Lateral line scale count = 118
The ray count and the scale count are at the high end for Redfin.
The pore count could be either Chain or Redfin
But the ray count though on the high end for a Redfin, is below the minimum number for a Chain.
So I would assume that this fish was indeed a Redfin, or possible hybrid Redfin x Chain. But would rule out pure Chain.
Though remember that this fish outgrew another redfin 2 to 1. Possible heterosis?
This fish was 4-6 inches in August, and today it measured 11.75 inches, quite astounding growth for a Redfin.

In your experience is this common? So should we all make sure to have a nice top on any pickerel tanks?
Fish died. After being vigorously courted by a large grass pickerel for two days, the fish in question which was totally uninterested, and fairly disgusted, found a hole and took a leap. Sad, but I was able to do some ID work on it.

i dont know much about red or grass pickerel but i was under the understanding that a grass was a mix between a red and a chain???????????? if this is true then wouldnt a hybrid just be a grass????????? i am prob way off cause before a couple days ago i didnt now there was any kind of pickerel besides chain
Chain Pickerel = Esox Niger
Grass Pickerel = Esox Americanus Vermiculatus
Redfin Pickerel = Esox Americanus Americanus
Grass Pickerel and Redfin Pickerel are the same species. The Redfin Pickerel is a regional variant that exists to the east of the Appalacians. The Grass Pickerel is a regional variant that exists west of the Appalacians. For some reason, there are no pickerels in the Appalacians. There are intergrades in the Gulf coastal area.

I JUST finished acclimating the new guy and put him in the tank with the other. They are nearly identical in pattern, but the one I have been raising has got to be a chain now that I see them together and see snout length. I will post pics tomorrow hopefully to compare a 4 inch chain to a 4 inch redfin side by side.
