A semi-intensive method for spat production of the european flat oyster ( Ostrea edulis L.)

A semi-intensive method for oyster spat production was tested. Threa brood osyters liberated their internal larvae into a 5 m 3 plastic bag. The water in the bag was left stagnant for the period of pelagic larvae. The larvae were given PVC-plates as settling substrate and 7.9% of the observed pelagi...

Zusammenfassung:A semi-intensive method for oyster spat production was tested. Threa brood osyters liberated their internal larvae into a 5 m 3 plastic bag. The water in the bag was left stagnant for the period of pelagic larvae. The larvae were given PVC-plates as settling substrate and 7.9% of the observed pelagic larvae settled. A total of 130 000 flat oyster spat were taken out of the bag. The experiment was then repeated twice, with similar results. The experiment clearly demonstrated a promising method for spat production. The method is inexpensive and very little expertise is needed for success.
