The Rossmore Oyster ponds were established in 1969 by David and Bridget Hugh-Jones. We now have 22 ponds, and the aim of these ponds is to help breed the native oysters, Ostrea edulis. The ponds are located in the North Channel of Cork Harbour, Ireland. These seed natives are then moved to fatten and finish in the Helford River in Cornwall. As each oyster was settled onto mussel shell when it starts its life, it comes with a small bit of mussel shell attached, and this is how it is easily identified.
