Size‐related differences in behaviour and spatial distribution of juvenile Atlantic salmon in a novel environment
Within a month of first feeding sibling juvenile salmon had developed not only large differences in size (up to fivefold in weight), but also significant differences in behaviour. Large fish remained in refuges (overhead cover) significantly longer after having been frightened. On leaving the shelte...
