Morphomechanical study on the changes taking place in the course of the embryonic development of the bleak (Albur nus alburnus L.) conducted on the live fish in vertical and ho rizontal light beams, revealed that the cupies some 30% of the entire egg's ining 70% is the perivitelline space. The blastodisc and the before the hatching always take up lateral No lipid droplets (structural eggs of the other teleost fishes are present in the yolk mass of the bleak eggs. Biological justification of the above extraordinary phe-no mena as well as their adaptive importance is discussed.
