200 healthy common carps (Cyprinus carpio) were divided into the following groups (n=10 each): exposure to a magnetic field of 1) 0.1 mT for 0.5 hours, 2) 0.1 mT for 1 h, 3) 1 mT for 0.5 h, 4) 1 mT for 1 hour, 5) 3 mT for 0.5 h, 6) 3 mT for 1 hour, 7) 5 mT for 0.5 h, 8) 5 mT for 1 h, 9) 7 mT for 0.5 h, 10) 7 mT for 1 h. For each group, a separate sham exposure group was used. After (sham) exposure, fish were returned to their aquaria for 2 weeks.
acrylic experimental cubes (15 cm Π8 cm Π6 cm) filled with aquarium water and placed inside the coil
Setup
cylindrical coil, 50 cm in length, with inner diameter of 9.6 cm and outer diameter 11.5 cm, made of 980 turns of 2.5 mm diameter enameled copper wire; fish were positioned inside the coil on an elevated platform to ensure all of them received the same magneticfield intensity; the coil was located in an east-west direction and the magnetic field was parallel to the long axis of fish body; temperature was maintained at 16°C
