Bullheads are considered an absolute delicacy in parts of Michigan, Wisconsin, and Minnesota.
Several years ago a few PB friends gathered at Sunil's pond to harvest at least150 pounds of them. We had a lot of fun doing it. I brought a few of them home.
They were a hefty bunch, averaging somewhere between 1.5 to 2.5 lbs.
The fillets provided the main attraction for a Father's Day party and a 4th of July party. Each party was attended by about 40 friends and relatives, and nobody went home hungry.
I'd rather that they don't invade my ponds, but if they do -- I'd just catch them, invite some friends to a party, and eat those tasty fish.
