The effect of electromagnetic waves of cell phones on hematological and reproductive indices of koi fish (Cyprinus carpio) brood stocks

Nowadays, it is necessary to be considering the effects of electromagnetic waves caused by modern technology on fish. The effect of mobile electromagnetic waves (900MHz) was studied on some of hematological and reproductive parameters of koi fish female and male brooders in 10 days and in 3 experimental groups: control (without receiving waves), treatment 1 and treatment 2 (4 times a day and each time for 30 minutes in faced with mobile phones, in a “stand by” position and in a “calling mode” respectively). At the end of the experiment, blood samples were collected from the caudal vein and the blood parameters (RBC, WBC, Hb, Hct, MCV, MCH and MCHC) were determined with the current hematological methods. The level of GTH II was measured by radio immunoassay (RIA). The GSI and HSI indices were also calculated by measuring gonad and liver weight, respectively, and their ratio with body weight. The reproductive success in the males and females of control group was more than the other two treatments. In both sexes, the HSI of treatment 2 significantly increased. The lowest mean of RBC, Hb and Hct was in the females of treatment 2, and, the highest levels of WBC and neutrophil and the lowest percent of lymphocyte belonged to the males of treatment 2. The results showed that mobile-induced electromagnetic waves produced numerous negative biological effects on female and male of koi fish.
