broodstock
Parent fish group
Broodstock are the adult fish, shellfish, or other aquatic animals kept specifically for breeding purposes.
In aquaculture, maintaining healthy broodstock is essential for producing the next generation: The hatchery selects its broodstock from the strongest specimens.
The term applies to any species raised commercially—salmon, oysters, shrimp, tilapia.
