The effect of a 100-300-fold attenuated geomagnetic field on the embryonic development of great ramshorn Planorbarius corneus and oxidation-reduction properties in water environment were studied in a hypomagnetic chamber. Mainly the hypomagnetic field effected beneficial influence on the development of mollusks: teratogenic effects were less massive, i.e. embryos that first occurred in hypomagnetic conditions were characterized by low death rate. The mobility index increased in embryos on the stage of late veliger and post-metamorphosis. Under the sharp increasing of the magnetic field to the normal level the embryos and juvenile mollusks rapidly perished (practically, their growth was stopped). Type of induction was dependent on adaptation of juvenile P. corneus to a magnetic field. Mollusks growth in the normal geomagnetic field would prefer the conditions with maximal induction, whereas mollusks developed in the hypomagnetic chamber, on the contrary, chose the conditions with minimal induction. It was revealed that the oxidation-reduction potential of water increased as magnetic induction attenuated pointing to a natural decline that testifies about the regular decreasing of internal energy of water molecules, which, in our opinion, is caused the inhibition of the mollusk embryonic development.
