Scottish fisheries, in the Firth of Forth, around Shetland, and on the westĬoast, with the exception of Loch Ryan, are no longer important commercially.Īttempts are being made at the present time, with some success, to grow and That previously flourished around Swansea and Milford Haven is no longer active,Īlthough there are some recent signs of a revival, and previously active Suffolk and Whitstable in Kent, on the south coast between Chichester and Poole,Īnd on the south west coast between the rivers Dart and Helford. Present time (1980) are on the south east coast between the river Blythe in The three most important fishing areas in the UK at the Winters have all taken their toll over the years, and stocks are only nowīeginning to recover. Overfishing, pollution, pest infestation, unfavourable summers and severe Native oysters have been fished around the coasts of the UK at least since Roman times, and were for long an important part of the nation's diet. The name oyster is written in other languages as All species can grow to a size of about 100 Mm, measured across the shell, depending on local bylaws, and Pacific oystersĪre marketed from 60 mm upwards. Native oysters are marketed when they reach a size of 62-64 All show a wide variation in shape, colour and Ridges, but Pacific and Portuguese oysters are not always readilyĭistinguishable from each other. The native, while the shell of the Portuguese oyster usually has even sharper Pacific oyster is more deeply cupped, rougher and more elongated than that of One half of the shell almost flat and the other half cupped. The native oyster is roughly fan shaped, almost circular, with Oyster is sometimes called the Japanese oyster, but these names are not The native oyster is sometimes called the flat oyster, and the Pacific The name native, Pacific or Portuguese oyster is restricted to the appropriate The Portuguese oyster, CrassostreaĪngulata, is no longer grown here, imports of seed having ceased in 1970.Īll three species may be offered for retail sale simply as oyster, but use of Native oyster, Ostrea edulis, and the Pacific oyster, Crassostrea Three species of oyster are met with in the UK trade. Some information is also given on grading, yield and composition, and Storage of whole oysters and oyster meats, and the preparation of oyster More detail the handling and distribution of live oysters, the freezing and cold Since installation, there has been a marked increase in biodiversity at both locations.This note describes the species of oyster marketed in the UK,īriefly describes cultivation, harvesting and cleansing, and then discusses in The inaccessible nature of the work, combined with working with the delicate young oyster spat and large tidal fluctuations, required a substantial amount of pre-planning and coordination between project partners in order for this project to be a success. Both reefs were located in approximately 3-10′ of water (large tidal fluctuations) and were accessible only by boat. Similarly, at the second location, ER&M placed and secured a number of pre-spatted concrete “reefballs”, with the same intent of re-introducing a living oyster reef to the site. The purpose was to re-create a living oyster bar, raised high enough above the surrounding bottom to protect it against the suffocating effects of siltation. At the first location, ER&M utilized clean, bagged shell to create a containment structure within which loose native shell was placed to create a raised “base” on which pre-spatted shell (clean oyster shell with attached live young oysters) would be deposited. Scope: ER&M was tasked with creating new oyster beds, utilizing 2 separate techniques, at 2 locations within a coastal bay.
