Catchment : At the age of 3, the oyster begins its reproductive periods in June, July. It is milking and then this milk is being freed in July. The plankton turns into a larva that can be carried away by currents.
Oyster farmers who know the locations where the larvae will go, place collectors (Plastic tubes, cups) in these passages for catches. 15 days later the set young oysters form their shells, begin to nourish themselves and grow. Only two basins in France are in favour of natural reproduction: ARCACHON & MARENNES-OLERON.
½ Raising: Between 18 and 24 months, oysters are separated from the collectors which remained glued per 2 or 3 and then placed in farms on the ground for 1 year, they are recovered with a fork to be separated (separated 1 by 1) then ready-sized, the oysters are placed in plastic bags on tables, in half-raising farms for 1 year, where pockets are turned regularly.
The raising: The year passed, these oysters are changed farms for a ready-finish of the shell and quality of meat of the shellfish during this long period, the vigilance of oyster farmers is damned. Predators are numerous (Starfish, Percing abalones, Birds, etc.) during this period of 4 years, bad weather and heat have also caused considerable losses sometimes. We just have to mature them in fattening ponds. The last year the oyster can be as raised in fattening pond as which earned it the appellation Pousse en Claire.
