Some preliminary studies of the effects of a static magnetic field on the life cycle of the Lebistes reticulatus (guppy).
Lebistes reticulatus (guppy) was subjected to a continuous treatment of a 500-G homogeneous magnetic field within a specially designed horseshoe magnet encompassing a small aquarium. The experiment was carried through several generations with the following results: in the first generation, the brood size was normal but the gestation period was reduced by 30%; the second generation had an average reduction of spawn rate of 50% and a reduction of the gestation period of 30%; and in the third generation, reproduction was completely inhibited as long as the fish remained within the magnetic field.
