Title

2011 Devon and Severn IFCA Taw Torridge Mussel Stock Assessment

Abstract

Stock assessment of the mussel beds on the Taw Torridge Estuary, carried out using the Dutch Wand methodology. The results include 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 of the eight beds. This survey forms the baseline of data for the mussels on the Taw Torridge, against which all future stock assessments will be compared.

Lineage

The data was collected by the Devon and Severn Inshore Fisheries and Conservation Authority. Transects were 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 were compared to the 2001 survey conducted by Cefas.
