The volitional travel speed varies with reproductive state in mature female brown trout Salmo trutta.
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.
