The aim of the scale sampling programme is to monitor and detect any changes to the stock structuring of the Dee’s salmon and sea trout populations. Scales provide us with information on the age composition of our salmon and sea trout stocks and the frequency with which they repeatedly spawn. Scales also highlight growth patterns of fish whilst at sea.
270 salmon scales and nine sea trout scales were sampled on the Dee in 2012 by Ghillies and angling club representatives. The Trust’s scale sampling programme started on the Dee in 2008 and previous reports can be found at http://www.riverdee.org.uk
