Exe Estuary Cockle Stock Assessment 2012 to 2017
Since 2012 Devon and Severn IFCA has carried out stock assessments on the public mussel beds on the Exe Estuary, south Devon. 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.

Data is collected by Devon and Severn IFCA, during March or April each year. 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.
