In 2018 Devon and Severn IFCA has carried out a stock assessment on the public mussel beds on the Teign 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.
