Nevertheless, little is known about the mechanisms and nature of local adaptation to specific environments in stream living salmonids. Using an interdisciplinary approach involving behaviour, physiology and genetics I will examine fitness variation among families adopting different behavioural strategies in a range of habitats in the wild. Previous studies performed in laboratory conditions have shown that dominant, more aggressive individuals grow faster than subordinates. This project consists of three interrelated parts: 1) Behavioural variation among families of salmonids and consequences for survival, growth rate and dispersal in habitats of different complexity. 2) Spatial and temporal space use in the wild in relation to various behavioural strategies. 3) Physiological costs of different behavioural tactics and foraging positions in the wild. By incorporating molecular tools into all three interrelated parts I will be able to relate family differences in behavioural properties to factors such as growth, dispersal and movement at various foraging sites. The results from my research can aid in understanding local adaptation and the structuring of populations, which in turn may facilitate development of stocking tools as well as guidelines for protection and restoration of salmonid populations.
