Sol Azul has adapted to Mexico the French farming method for oyster production using plastic bags placed in intertidal beds. Rebar “beds” are placed directly on the intertidal zone, with Redlon polyethylene bags with the oysters resting on the beds. The beds do not require any concrete work and are completely movable, allowing the free exchange and movement of water. France produces some 130,000 metric tons per year of oysters using such technology. Similar techniques are used in the US and Canada. This farming method has the advantage to keep oysters growing individually and never in contact with the bottom.
From their birth oysters feed exclusively on the natural algae that grow in the water column (phytoplankton). Water currents and tides produce a continous exchange of water and natural food. Healthy sun expossure during the low tide keeps oysters clean and healthy, resulting in an extraordinarily clean product with extended shelf-life.
Sol Azul uses hatchery-reared oyster “seed” which are later transferred to grow in bags set over beds in intertidal flats. We use non-GMO biological triploid oysters, having several natural advantages over traditional diploid organisms; namely:
• Better resistance to high temperatures and higher growth rates.
• Triploid oysters are non-fertile so all metabolic energy is put into growth.
• Because triploids do not reproduce the risk of displacing other species are greatly reduced.
