Hey, that's my fish! Now I know where you were looking for answers, Tim. To respond to this for others to see, numerous biologists here in MN have said it's a GS x PS cross. They also stated that it's nearly impossible to tell the difference between hybrids when a green sunfish is involved. The fisheries boys would count this as a green sunfish or a hybrid and toss it back. They wouldn't classify it any further. One researcher asked for samples from the fish we've been catching, as pumpkins are rare in this waterway, and green sunfish even rarer. These fish are abundant however. I'm sticking with green x pumpkinseed until the Jerry Spring DNA test confirms it... ;)
