These surveys determine the area of each bed, the density of mussels, the percentage cover, and the estimated stock (in tonnes), and marketable stock (mussels greater than 50mm in length) for each bed, and are used to assess the condition of the bed and whether the bed could support a viable mussel fishery.

Transects are walked across each mussel bed using the Dutch Wand method of surveying, data on the extent of each bed was also used to create GIS layers of the area of the beds. Results are compared to those from previous years.
