EMSWORTH OYSTERS

Oyster regulation and the “R” month tradition
Until the early 19th century, oyster fishing was largely unregulated, with independent fishermen moving from one depleted bed to another and showing little concern for conservation. As stocks declined, fishermen travelled further, with East Coast and French crews crossing the Channel, and Emsworth oystermen later working as far as the North Sea, Falmouth, Normandy and Brittany. In 1843, Britain and France agreed a Convention banning dredging during the May-to-August breeding season. This protected stocks, avoided poorer-quality summer oysters, and helped establish the tradition of eating oysters only in months containing an “R”.

Rivalry, co-operation and protection of Emsworth’s oyster beds
By the mid-19th century, East Coast oystermen were co-operating with Emsworth, using the sheltered harbour to overwinter young oysters. Yet rivalry remained, with disputes involving Beaulieu fishermen, East Coast crews and Matthew Russell’s private beds at Ware Island. Emsworth fishermen accused others of stripping their harbour and damaging their trade, while also expanding into French and East Coast waters themselves. In 1871 they formed the Emsworth Dredgermen’s Co-operative Society, gaining rights over 300 acres of harbour. They also protected oysters in foreshore pens, though some supposed oyster-growing structures were probably eel traps.

Expansion, decline and the typhoid scandal
In the early 19th century, French, Dutch and English oyster fishermen crossed the Channel in growing competition, depleting natural breeding grounds. Artificial beds, protected ponds and larger boats allowed wealthier operators to dredge further afield, pushing smaller fishermen out. By the 1880s, merchants James Duncan Foster and John Kennett dominated Emsworth’s oyster trade, acquiring many foreshore pens while others fell into disuse. In 1902, Emsworth oysters served at banquets caused typhoid outbreaks, killing the Dean of Winchester. In 1903, London’s Fishmongers banned Emsworth oysters and the harbour trade collapsed.

War, recovery and renewed threats
In 1914, Emsworth’s new sewage system stopped raw waste entering the harbour, but the First World War prevented the oyster trade from recovering, as men were called up and shipping was restricted. Between the wars, the industry revived on a smaller scale, with harbour beds recovering and over 40,000 spat seeded in 1936. Catches reached about 100,000 oysters a week, but fertiliser pollution and pleasure-boat moorings threatened the beds. The Second World War brought another collapse, with labour shortages, boating restrictions, enemy attacks near Thorney Island and major oyster losses at Hayling.

Post-war revival and modern pressures
After the Second World War, Emsworth’s oyster industry recovered slowly. In 1958, the Emsworth Dredgermen’s Co-operative Society tried to revive it by testing oyster breeds, planning to reopen Fowley Island ponds, checking pollution and restarting dredging. Poaching remained a problem and the trade never regained its former scale. Further efforts in the 1970s and 1980s introduced Pacific oysters, with 33 tons dredged in 1985 and sold for £56,000. However, pollution from pleasure-boat anti-fouling paint harmed oysters, while only 10–15 boats continued small-scale dredging.

The end of Emsworth’s oyster industry and hope for the future
By the beginning of the 21st century, Emsworth’s once-thriving oyster industry had effectively ended. Although the Emsworth Dredgermen’s Co-operative Society continued to exist, many members were no longer active fishermen and some no longer lived locally. The local dredging license lapsed and was picked up by a large international cooperation and, as the new season opened, large trawlers were plundering the harbour waters once more. The already fragile oyster stocks - and other delicate ecosystems - suffered huge damages.

Recognising the impacts, the Harbour Conservancy revoked the license, banning trawling in the harbour. Today this ban stands as well as legislation stopping any Chichester Harbour shellfish being sold for human consumption. Although poaching is still an issue.

Hopes for the future of Emsworth oysters must come from a balanced approach of dedicated oyster restoration, alongside wider ecosystem protection against pollution and habitat pressures.
