Hydrokinetic Turbine Effects on Fish Swimming Behaviour
Figure 7
Distance between fish and rotor for body shape categories of fish.
Means and 95 % confidence intervals of the closest distance (metres) between passing fish and rotor centre, during control conditions and in the presence of the rotor. The dotted line indicates the outer edge of the rotor. Only fish observed within the camera stereo-field are included. Body shapes: C compressiform (control n=201, impact n=129), F fusiform (control n=249, impact n=134) and G globiform (control n=9, impact n=5).
