【Abstract】 Seawater treated with magnetic field produced good biological effect on artificial rearing of young prawns and shortened the period of raising them to fully grown size. The survival rate of young prawns living in seawater treated with magnetizing device under three different intensities: 1, 600G, 2, 400G and 3, 000G all increased significantly, with an average increase of 17. 90%. The indoor survival rate of prawns was 78. 5% higher and their body length 10. 56% greater than that of the control. This was in large part due to a series of changes in physical and chemical properties of the seawater caused by the treatment, which promoted the metabolism of the young prawns and increased their resistance to diseases.更多还原
