Summary

Cornwall Inshore Fisheries and Conservation Authority (IFCA) conduct annual dredge surveys within the Fal Oyster Fishery since taking over management of the fishery in 2014. The purpose of the survey was initially to assess the distribution and abundance of native oysters (Ostrea edulis) within the Fal Fishery management area in the River Fal, Cornwall. Since 2016, the survey has been developed to also assess queenies (queen scallop, Aequipecten opercularis; variegated scallop, Mimachlamys varia) distribution and abundance. The aims of the survey were to investigate the relative abundance and distribution of native oysters (O. edulis) and scallops (queen scallop, A. opercularis; variegated scallop, M. varia) within the Fal Oyster Fishery. Slipper limpets (Crepidula fornicata) were recorded at each site using a SACFOR style scheme. Species of bycatch were also recorded across the survey area as a list of species present. In 2016, a total of 89 sites were completed and a total of 1665 oysters and 3257 scallops were recorded. The analysis was done by Geographic Area; Outer Harbour, Harbour and River.
