Historic accounts place Ostrea edulis at the centre of important local fisheries in South Wales back to the Roman occupation of Britain and describe a fishery supporting 200 vessels landing over 9 million oysters at its peak in the 19th century. Ostrea edulis are found on a wide variety of firm and stable seabed habitats where clean hard surfaces exist for larval settlement but it is likely that more complex habitat forms have historically existed including oyster banks and reefs. The aim of this study was to identify the scope and potential approaches for restoration of native oyster populations and habitats in South Wales. The associated report describes the options for practical approaches for restoration of the native oyster in its natural habitat in South Wales to meet UK and Welsh Biodiversity Action Plan (BAP) targets for recovery.
