We limited out on Dolphin in Key Largo while in rough seas. We trolled while looking for sets of birds. We caught dolphin from 150 to 750 feet. When you get close to the birds throw out ballyhoo, leaded skirt, or chunk bait on a J hook. When you hook a dolphin leave one in the water because it keeps the other dolphin around.
