The proposed growth pockets are robust and manufactured with diamond mesh patterns, available in mesh sizes from 6 to 18 millimeters. The pockets are semi-rigid and shaped according to the producer's specifications and dimensions. 

  • The float is attached in the pocket with zip ties.

Ostrea & Tricks

The Roll Block attachment and the T-Ostrea textile tie allow a 360° rotation of the pocket around the bar.

Indeed, this system allows the pockets to follow the tide level naturally thanks to the float and to naturally stir the oysters.
