The volitional travel speed varies with reproductive state in mature female brown trout Salmo trutta
Abstract:This study tested the effect of reproduction on the volitional travel speed of mature female brown trout Salmo trutta L. The downstream travel speed in the pre-spawning state was 0·25 m s−1 (95% CI : 0·19, 0·34) while it increased significantly to 0·65 m s−1 (95% CI: 0·49, 0·87) in the post-spawning state. The results suggest state-dependent travel speed in S. trutta.
