Summary

Motivation flat oyster pilot in wind farms. Flat oyster beds provide natural hard-substrate habitat in a predominantly soft-bottom marine environment. In addition, they change environmental conditions by filtering, nutrient recycling and carbon storage. Hence, North Sea marine life, probably even including fish production, will increase when flat oyster beds are restored. Since bottom-trawling fishery is excluded in wind farms, an essential condition for flat oyster restoration is fulfilled here. Basic conditions for flat oyster growth and reproduction, such as food availability, sediment composition and sea floor stability, are also met in several wind farms off the Dutch coast. Hence, flat oyster restoration in wind farms constitutes a potential marine biodiversity enrichment opportunity. The current report provides key information on design, deployment, monitoring and final removal of a flat oyster restoration pilot in a wind farm in the Dutch part of the North Sea.
