Pumpkinseeds are a beautiful fish. Not sure if they are prolific as bluegill and would become stunted. Like Pike, The chains like marshy areas to reproduce but I think the pickerel will reproduce even in the pond as long as there is some submerged vegetation. I think northern pike are more finicky about needing marshy shallow areas for reproduction. Like Bill Cody said, they can become stunted especially if food is scarce, but they are very cannibalistic and may self balance in a small pond.
