Wyre and Rousay Sounds NCMPA

Status: Designated


Site overview This site was designated to protect maerl beds and the kelp and seaweed communities found here. These types of habitat act as a refuge for juvenile fish and a safe feeding ground for larger marine animals.

At risk The use of bottom towed gear throughout this site should be limited because maerl beds are easily damaged or even destroyed when fishing in this way, and they can take up to 10 years to even start to recover.
