The micro-nursery

Micro-nurseries receive larvae from larval breeding.

These developed larvae, called pediveligerous eyed larvae, due to the appearance of a small black dot resembling an eye, continue their development within the micro-nurseries. They will metamorphose there, in pools supplied with filtered sea water, supplemented with phytoplankton for adequate nourishment.

The metamorphosis allows the larva to transform into a real small shell, the micro-spat. This will remain in micro-nursery breeding until its size allows it to be raised in good conditions outdoors, within the nurseries.

ℹ️ During this step, in order to obtain so-called “one by one” oysters, we breed the larvae, seeking their metamorphosis and settlement on their rock, in the presence of oyster shell powder. This microbroken powder, made of flakes less than one millimetre in size, allows each larva to find its flake (its rock) and attach itself to it!
