What is the effect on shellfish, such as oysters and mussels?

Mussels and oysters respond to underwater noise by closing their valves, causing food intake to stop temporarily. ONE-Dyas has commissioned a study of the existing literature on the subject. ONE-Dyas is also prepared to commission additional research into effects on non-protected species such as shellfish and marine crustaceans. The EIA examines which techniques can be used to minimise the impact of the activities.
