The Tollesbury & Mersea Native Oyster Fishery Company Ltd was formed on 15th December 1876.

oyster dredging At that time about 640 men and 120 oyster smacks were employed from the villages of Tollesbury & Mersea. The apprenticeship was four years and the average earning for an oyster dredgerman was 10 shillings a week (50p).

Two types of shares were allocated: one for capital investors, one for dredgermen and others working in the fishery. The idea was that by buying into the Company stocks would be protected and returns stabilised. Daily management of the Company was by a Jury or committee of twelve members from Tollesbury and Mersea. On a rota basis decided by the Jury, members’ smacks worked dredging in the river in order to fairly distribute income from the fishery.

unloading oystersThe oyster industry had been booming during the middle of the 19th century with most of the stock being sent to Whitstable for relaying. There was, however, serious rivalry between the fisheries along the Suffolk, Essex and south coast and poaching of oysters and culch (marine shell eg old oyster shells) was not uncommon. To protect against theft or illegal dredging the Company had three Watch boats each manned by one person. Even in the 1920s oyster policeman were seen in the Blackwater.



oyster shucking The smaller smacks carried three hands for dredging, each working one dredge. The catch was then transferred to another smack with a juryman of the Company on board and the catch taken to the Packing Shed where it was sorted by jurymen standing at long benches, culling oysters into the various grades for sale or to be re-laid as stock. The layings in the creeks were dredged in open skiffs by haul towing (pulling the dredge by hand).

The industry carried on quite lucratively until the first and second world wars when men were drafted and mines and barbed wire were laid along the shore and in the river, making dredging and “picking up” (gathering oysters by hand) quite dangerous. In the latter half of the twentieth century harsh winters devastated the breeding stock. The Company was bought out by Mac Fisheries who over the next few years, having sold any natives they could, neglected to restock, clean the ground or lay more culch. This inevitably led to poor returns and the loss of interest by the owners.

oystersThe Blackwater Oysterman’s Association (BOA) was formed in 1979 to bring the oystermen together into one co-operative working group. In 1983 with the help of the BOA the Tollesbury & Mersea Native Oyster Fishery Company was bought back from Mac Fisheries and the Company set about repairing the neglect of its previous owners. Pressure was put on Anglian Water to build a new sewage treatment works to improve water quality, the silted seabed was cleaned, new culch laid and purification tanks built. New stock was imported as there was estimated to be less than 10,000 native oysters left. Since that time the Tollesbury & Mersea Native Oyster Fishery Company has endeavoured to continue to improve the quantity and quality of stock.
