With the recent demand of restaurants serving oysters in the half shell, many farms are moving away from filling mesh bags with their discarded shell. Historically, the discarded shell was placed back in plastic based mesh bags in the bays where oyster larvae could grow. Recent farming technology is evolving, and farms are beginning to raise oysters in hatcheries to cater for the live market. This prevents the oysters from cementing to each other and allows them to grow individually. Many of these farms are now looking to reduce, recycle and reuse their discarded shells.
