Aymeric goes to work!
One month and a half after the graft (operation made on the oysters to make pearls), we have to check the oysters. Just after the grafting operation*, we put the oysters in fine mesh bags, before getting them back on the breeding lines. Now it's time to take them out, to control the retention rate, check if the oysters kept the nucleus. We simply look if the nucleus in the pouche, if it is, it means that the graft did not success and the oyster won't give us a pearl.
Oysters that have passed the check are carefully tied into the kangaroo baskets*, where they will stay until they have enough strength to resist to predators, or until the harvest in 18 months.
The remaining oysters are tied along a red rope and put back in the water on a transit line to make keshis or to serve as graft demonstrations for visitors.
(*) Graft operation: when we introduce into the gonad a small piece of the lips giving oyster (cell secreting mother-of-pearl) and a nucleus (small sphere) to produce a pearl.
(*) Kangaroos baskets: Basket nets with pouches in which we put the oysters.
The first day of check is satisfying, over 1500 oysters controlled, there is more than 80% of retention rate (more than 80% of the oysters kept the nucleus and are going to produce a pearl). It seems that Ben and his team have done their job. We just hope pearls will be pretty and good quality, rendez-vous in 18 months!
It's now up to us to take care of the oysters so that they can develop well and make beautiful pearls.
