LICHEN OYSTER REEFS

Artifical oyster reefs constitute a key part of the transitional park, forming the second line of defense for the seagrass meadows and inner harbor.

The concrete reef units were designed with the intention of maximising the probability of succesful oyster larvae attachement by increasing the available surface area, while providing verticality and sheltered spaces. The textured surface provides additional opportunities for organisms to attach.

As new larvae attach to old oyster shells, the oyster reef will gradually increase in height. The artificial reef units will contribute to this by providing an immeditate vertical presence which will allow larvae to more easily attach on the textured surface and increase with sediment retention. The recycled concrete will be mixed with an eco-mix of concrete provided by Econcrete, to improve it’s compatibility with marine flora and fauna.
