The study was conducted to evaluate the effect of 900MHz radiofrequency - electromagnetic waves ( RF-EMW ) sent out from mobile phone on spawning and gonadotropin hormone II level in male and female brooders of Pterophyllum scalare. 54 mature male and female angelfish with weight of 6.7±0.5 g and length of 76.9±2.3mm divided into three groups including control, exposed groups 1 and 2, and each group with three replicates. For 10 days, experimental 1 and 2 groups were exposed to three mobile phones 4 times a day and each time for 30 minutes. The experimental group 1 was exposed to non-calling switched-on mobile phones and the experimental group 2 was exposed to calling mode mobile phones. The concentration of GtH II measured using ELISA method. Three pair of fishes of control spawned during the test. The results indicated that in the level of GtH II of females increased significantly in exposed group 2 in compared to other groups. In males, the level of GtH II increased significantly in exposed groups 1 and 2 in compared to control group.
