| Electric currents make changes and physiological effects on fish and affect reproductive indicators such as gamete quality, corticosteroid levels and ovarian function. In this study, 180 pieces of zebrafish were placed in 12 plastic containers, each of which contained 1.5 liters of city water, and were classified into 4 groups. Then the groups were affected by three different doses of electromagnetic waves (with intensities of 2.5, 5 and 7.5 milli Tesla) chronically (28 days). One group was also considered as a control. After the end of the exposure period, the histological examination of ovarian tissue showed that long-term exposure at the intensity of 7.5 milli Tesla has a greater effect on ovarian tissue than the intensity of 2.5 and 5 milli Tesla. So that a higher percentage of oocytes leave the normal process and enter the atresia phase. These oocytes will not have normal fertilization if released. Increasing of magnetic field intensity is associated with increasing of oocyte diameter so that the size of the oocyte reaches its highest level at the intensity of 7.5 milli Tesla. In general, the presence of magnetic waves in sea waters may affect the reproduction of marine organisms in the long term. |
