National Fish Hatchery System. Image Details. The National Fish Hatchery System works to support healthy, self-sustaining populations of fish and other aquatic species across the country. Every year we raise and stock over 100 million fish to support the recovery and restoration of imperiled species, recreational fishing, and tribal subsistence fisheries.
The Maryland Department of Naural Resources Fishing and Boating Services Hatcheries Division is responsible for production of nearly two dozen species for fish stock enhancement, education and outreach, shellfish production, cooperative fish culture projects, and restoration of anadromous species in Maryland waters of the Chesapeake Bay. A variety of strategies are used to raise fish for stocking, including intensive culture, extensive culture and integrated culture.

By 2000, biologists estimated that fewer than ten adults were returning to the basin annually. On September 11, 2001, an effort began to collect the last remaining juveniles from drying pools in one of the few streams where they were found.
The fish raising cycle begins with the return of the adults to the hatchery in the fall and winter. The adults remain in holding ponds until they are mature enough to spawn. During spawning events, we sort the fish based on species, maturity, and sex. Afterwards, we remove the females' eggs, fertilizing and cleaning them, before placing them into incubation trays.
