El The production process for larvae and seeds in the Cultimar Hatchery is described in the adjoining diagram:

The farming processes for Japanese oysters as followed by most of our clients may be divided into 2 different trends:

  • From individual seeds that can be grown on inter-tidal racks or suspended on long lines in lanterns or in hanging nets.
  • From remotely set larvae, using collectors that are then separated, ending up with individual bunches containing a series of substrates, usually scallop shells, to which the oysters cling in variable amounts.


The growing period varies depending on the starting size and on the bio-oceanographic conditions (temperature, nutrients, etc.) of the site used, from 6 months in warm waters up to 30 months in cold waters.
