Capt. L. Shields who resides near Corydon, Indiana, is a most successful
breeder and raiser of German carp. He states that when he wishes to feed
the fish he goes to the pond and rings a small bell. Instantly, the fish
from all parts of the pond start for their feeding place and gather in
immense numbers near the shore and fight for the particles of food when
thrown to them.
