Hydrodynamic quantificational measures of zebrafish pectoral fin movements (a) pictorial representation of zebrafish pectoral fin movements (b) experimental image of zebrafish pectoral fin movements (c) for the control group and (d) the Cochineal Red pigment 0.2‰ group. The vorticity contour is super-imposed with the velocity vector field (black arrows) generated during pectoral fin beatings (a) upstroke and (b) down-stroke of zebrafish larvae (6 d.p.f.).
