Remote Consequences of the Influence of Slow Magnetic Field Fluctuations on the Embryos of Roach Rutilus rutilus (Cyprinidae)

— The paper describes the remote effects of magnetic field variations with intensity of 100, 300 and 500 nTl and duration of 6 h on embryos of roach Rutilus rutilus . The exposure lasted from the 2nd to the 7th or from the 33rd to the 38th hours post fertilization. The impact of the investigated factors led to changes in the body length-weight parameters and redistribution of the vertebrae between the parts of the spine in underyearlings. Analysis of variance revealed a significant effect of the exposure time and the interaction of factors of the intensity of magnetic fluctuations, as well as different exposure times on the studied parameters
