Influence of Magnetic Field and Cu²⁺ Ions on the Early Development in Roach Rutilus Rutilus (L.) (Cyprinidae, Cypriniformes)

Abstract

Effect of the magnetic field (72.5 Hz, 150 T), solutions of Cu2+ ions (0.01 mg/l and 0.001 mg/l) and the combined effect of these factors on the eggs of roach Rutilus rutilus was studied. Survival and hatching rate of eggs, size-weight and morphological indices of fingerlings were considered. It is shown that the direction and intensity of biological effects caused by the combined effect of the magnetic field and Cu2+ solutions can differ from the effects caused by these factors separately.
