In-vivo measurements of nonstationary blood flows in Dannio Rerio fish embryo have been performed using laser Doppler microscopy technique. Time-dependences of the velocity of pulsatile blood flow in arteria and veina of the embryo have been registered by monitoring the heterodyne energy spectra of the Laser Doppler Microscope signal, generated by light scattered by moving erythrocytes. The spectral characteristics of the registered signal are discussed.
