Eggs of pike (Esox lucius L.) after period of adaptation (control) were subjected to 30 min action of the magnetic field (constant 4 mT and aletrnating 15 mT). The inflicted changes in the embryonic motories were observed under a microscope and recorded on videotape. The following aspects of the embryogenesis were affected: quasi-peristalsis, heart muscle action, somatic motorics. Three different mechanisms of the magnetic field are taken into consideration: directly on actomyosin structures in the quasi-peristalsis, on automatic centres of the developing heart, on developing structures of the central nervous system.
