Fish hatcheries were developed during the latter part of the nineteenth century in an effort to supplement dwindling fish stocks. In nature, fish lay thousands of eggs, but most juveniles die in massive numbers because of insufficient food, predators, and diseases. In hatcheries, eggs hatch under controlled conditions and juveniles are able to grow in a protected environment. These conditions result in diminished losses, and young fish can be returned to their natural environment in sufficient quantities to replenish populations.

In 1871, The National Fish Hatchery System (NFHS) was established by Congress through the creation of a U.S. Commissioner of Fish and Fisheries. In 1885, the first hatchery programs were undertaken by the NFHS in an effort to replenish shad and lobster populations. By 1916 the federal government operated more than 100 hatcheries, and many states also had opened their own hatcheries. Fish populations being augmented with hatchery stock included cod, pollack, haddock, flounder, salmon, and lobster.

Hatcheries were also involved in the intentional transplanting of species. Although most programs failed and new stocks did not take hold, there were notable successes. Shad and striped bass (rockfish), two of Atlantic species...
