Title: Regional juvenile salmonid monitoring programme : annual report 1993
Author: National Rivers Authority Welsh Region
Document Type: Monograph
Abstract:
The programme of juvenile salmonid stock monitoring was continued in 1993, the ninth year in succession that such a study has been carried out. The data collected is used to form baseline information on the status of juvenile stocks at both a catchment and regional level and can be used to monitor any changes to environmental factors both natural and man-made. As a consequence of the large number of catchments in the Welsh Region (over 50) covering 20,000 km of rivers and streams and given limited resources, not all catchments can be sampled in one year. Therefore, whilst several large key catchments are sampled on an annual basis the smaller catchments are sampled on a rolling programme.
