It does look like a pickerel, even small pike have some red or brown in the fins, that looks very green.
Very informative article, I live in Bristol but grew up in Burlington, drive through the town quite often. I saw the equipment being used to dredge that pond parked on George Washington trpk, thought it was to dig out the trout ponds a few years back. They forgot to mention the predation by bald eagles and ospreys up there too. I do like how it scientifically graphed why I caught absolutely nothing while I ice fished as a student up at UConn at MHR, 2006 and 2007. Nice post.
