This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and then reared for 60 days. The obtained results revealed that all growth indices were significantly (p < 0.05) improved by increasing in the EMFs intensity. 2 mT treatment indicated the highest final weight (43.95 ± 0.27 g), weight gain (6.83 ± 0.10 g), weight gain rate (20.94 ± 0.13 %), daily growth rate (0.38 ± 0.00 g day-1), specific growth rate (1.26 ± 0.01 % day-1) and the lowest food conversion ratio (p < 0.05). Survival rate had significantly (p < 0.05) increased in all exposed treatments compared to the control group.
