Figure 5. Mean ± SE number of green sturgeon that successfully passed the unscreened diversion pipe at sweeping velocities of 0.15, 0.38 and 0.61 m/s and water diversion rates of 0.28, 0.42 and 0.57 m³/s.

Significant differences in the number of successful pipe passages at different flow combinations are marked with different letters (P≤0.039 for all significant pairwise comparisons).
