The seasonal Native oyster (ostrea edulis) is native to North-West Europe.  It is fairly flat and almost round in shape.  The Mersea Native was recently awarded Presidia status by the Slow Food movement.  This award aims to protect the Native, which is under threat, but also highlights its exemplary quality.

The rock oyster (crassostrea gigas) also grows wild in the River Blackwater and is available to buy all year round.  It is is almost rock-like in shape and, because it filters a lot more water than its Native counterpart, is saltier in flavour.  

Both species of oyster are cultivated with a passion to produce something truly wonderful. The desire is to share the rich story of where these oysters are from and the history of the people producing them.
