National Broodstock Program’s Egg Distribution Service

The National Fish Hatchery System runs a National Broodstock Program that provides about 60 million fish eggs  to our partners every year. The eggs and resulting fish are used to support recreational fishing, produce fish to mitigate habitat loss due to dam construction, support Tribal fisheries, provide a disease-free source of eggs to make forage fish for endangered species recovery programs and support fisheries research.
