for the last two summers they have been along the NE coastline in vast shoals, some charter skippers reporting that there was that many they could see the shoals around their boats. Have haerd of one or two paties trying them as bait with a good deal of success, remember these are natural food for fish, and the vast shoals could show how the fish population has declined as not very mucj there to eat them, or the fish could be just eating their natural prey as they are plentiful. The lads who i have heard using them have broken them into piece 4 to 6 inches long.
