Operation Oyster - BSAC's UK diving conservation project

Did you know that the UK’s only native oyster, Ostrea edulis, is in decline, with a 95% drop in population numbers due to overfishing, disease, pollution and habitat loss?

But you can help us to protect this vulnerable species and reverse its decline by supporting BSAC’s Operation Oyster.

One of the largest environmental projects ever organised by BSAC (British Sub Aqua Club), Operation Oyster aims to engage members, divers and snorkellers in helping to rehabilitate the UK’s vulnerable native oyster beds.

Operation Oyster will include a nationwide citizen science project – launched in summer 2021 – through which divers and snorkellers can contribute to the data held on the native oyster populations around the British Isles.

Working with our partners – the Zoological Society London (ZSL), University of Portsmouth and the Blue Marine Foundation – all the data gathered by Operation Oyster will directly support the long-term restoration of the oysters’ natural habitat and ultimately increase their population numbers around the UK.
