In 1933 a german by the name of Jacobi, a Naturalist, collected live trout and kept them in artificial ponds. During the breeding season, Jacobi would express fish eggs and Milt (fish sperm) from the fish into a mixing container, then gently mixing them together. By doing so, he was creating a higher than normal success of fertilization of the eggs, compared to fertilization in the wild. After the eggs hatched, he would move the fish fry into larger ponds.
