   Sammanfattning : As all of Sweden's hydropower is to be re-examined within a 20-year period, methods are needed to carry out ecological investigations of dammed waterways. The first aim of this thesis is to evaluate whether methods for salmon and trout habitat mapping take all relevant indicators into account. LÄS MER

3. 2. Linking habitat characteristics and juvenile density to quantify Salmo salar & Salmo trutta smolt production in River Sävarån, Northern Sweden
