SAC Monitoring: Shad Egg Survey River Usk and River Wye (2012)

The River Usk and Wye are designated as a Special Area of Conservation (SAC) under the EC 92/43/EEC Habitats Directive for several features including twaite shad (Alosa fallax) and allis shad (Alosa alosa). Shads are migratory members of the Clupeidae (herring family) that ascend rivers to spawn in late spring. The populations of both species are threatened in Europe mainly due to obstructions to migration and issues surrounding water quality. In the UK, significant populations of shad spawn in the Rivers Severn, Usk, Wye and Tywi. The River Usk and Wye have been designated as a Special Area of Conservation (SAC) for shads and other features including salmon, lampreys and bullhead. The purpose of this data capture was to assist with the assessment of Favourable Conservation Status along the Usk and Wye to supplement the main shad spawning distribution condiftion assessment for the Usk (previous surveys conducted in 2010 and 2011) and the Wye (previous surveys were conducted in 2011). 7 sites were chosen along the length of the River Usk and 10 along the length of the River Wye. Both surveys were conducted between high river flows events, and work was carried out by qualified Countryside Council for Wales monitoring staff.
