r2002, herring is caught in the lakes I fish by using a sodium light mounted to the side of the boat. What happens is the sodium light running off of a generator draws in the herring to the top of the water under the light and the instant the net is thrown the light goes out so the bait cannot see the net. The bait fishermen around here fish from a 23' skiff with a HUGH tank the size of a septic tank in the middle of their boat to transport the bait. This is how the commercial fishermen catch the bait they sell.
