Broodstock development of groupers
2004
Mathew, Grace
The major constraint in grouper farming is the shortage and irregular availability of fingerlings trom the wild at theright time. For a regular supply of sufficient quantity of hatchery-produced seeds, healthy broodstock is highlyessential. Many of the culturable species of groupers arc protogynous hermaphrodites. They mature initially asfemales and latcr become males; in nature this transfonnation would take a very long time. Broodstock can either becaught from the wild or can be developed by rearing fingerlings in captivity.
