Calibration |
Once the
collected naissain, it is then appropriate to
sort it according to its size. It is thus gauged, first
once, put out of pocket, and installed on the ground or
oyster beds, same. Seven months are passed before a new
calibration. Meanwhile, the pockets will have been turned
4 times on average so to prevent that they do not push
wildly through those. |
Collecting |
The operation of
Collecting consists in collecting the larvae (invisible
with the naked il), laid by oysters thanks to
collectors (such as the tiles), immersed beforehand in a
mixture of lime and sand. |
Marketing |
It is spread out
over one year: the third year. The oysters wait their
hour of tasting patiently |
Shellfish farming |
Breeding of the
edible shells. |
Growth (period of...) |
Following the
second calibration the oysters are reinstalled again on
the parks where they will profit 11 months during, being
disturbed only by the transfer of the pockets (to avoid
which do not fix themselves at it). |
Désatrocage |
One month
separates us from now on installation from the tiles. At
present, it is advisable to clean oysters with to
separate them from various parasites such as naissain,
sponges, herbes
The oysters are then désatroquées
and the first oysters are ready with to be marketed. |
Détrocage |
Six months later,
the larvae became small oysters not larger than a nail of
inch and must then to be withdrawn from these tiles.
Formerly détroquées with the hand, the naissain is
recovered today mechanically. The lime-sand mixture then
plays its role of buffer between the tile and the
naissain. |
Abrasion |
Bridge ufs.
Their fecundation by the male. |
Oyster |
The oyster is one
bivalvular mollusc (2 asymmetrical valves),
lamellibranche (gills in plates), pertaining to the
command of the filibranches, the sub-order of the
anysomyaires and the family of ostréidés, which
according to species' is high (or, more rarely, fished)
for her flesh, or for its invaluable concretions
(mother-of-pearl, pearl). |
