TENS of thousands of “small but mighty” oysters have been dropped into the Harbour to improve water quality.
The 50,000 mature oysters, which have have a combined weight of nearly 6,000kg, are capable of filtering around 9.5 million litres of water daily.
The project uses “triploid” oysters, which are sterile and do not reproduce. This allows them to grow faster and remain plump year-round, providing consistent water filtration.
They are also safe for marine environments and are commonly used in aquaculture due to their resilience and efficiency.
Ports head of maritime operations Louise Stafford said: “Oysters, small but mighty, possess an incredible ability to filter water.
“We are aiming to harness this natural skill to further improve water quality in the harbour.”
She continued: “We’re grateful to the Jersey Oyster Company, who have helped to provide these triploid oysters, which will play a crucial role in filtering the water.
“We’re now considering similar projects in other areas of our harbour.”
The oysters have been placed beneath Albert Pier, under the marina access ramp, and next to the accommodation pods.
Their health, and effectiveness in improving water quality, will be closely monitored to help inform future environmental initiatives.
Chris Le Masurier, the owner of the Jersey Oyster Company, added: “We are incredibly grateful to be collaborating with Ports of Jersey on this innovative project.
“This initiative not only highlights the remarkable natural abilities of oysters but also underscores our commitment to sustainability.
“By working together, we aim to make St Helier Harbour a cleaner, healthier, and more sustainable environment for future generations.”
