These Rivers are designated as Special Areas of Conservation (SAC) partly because they support internationally important populations of twait shad. Allis Shad is also a feature of the sites and a secondary reason for selection as a SAC. Records of other species of freshwater and estuarine fish are also recorded as part of this dataset. This provides a collation of existing knowledge, habitat and shad data, and provides evidence to design and implement a suitable juvenile monitoring programme for their condition assessment. There were 5 survey sites along the River Usk, 5 sites along the River Wye and 5 sites along the River Tywi. Further data is available in paper format in the associated report with historical records of eggs surveys extending back to 1980. This historical data is collated from the Environment Agency.

Juvenile shad seine netting was undertaken in September and October 2005 and July 2006 in accordance with protocols described by Hillman et al (2003). Each sample station was netted multiple times and counts recorded for each. All fish were measured and a sub sample identified to species, using gill raker counts. The confidence in this dataset is high as it was undertaken by experienced staff.
