Sensitivity of American Eels ( Anguilla rostrata ) and Atlantic Salmon ( Salmo salar ) to Weak Electric and Magnetic Fields
Two long distance migrating fishes, the American eel (Anguilla rostrata) and the Atlantic salmon (Salmo salar), consistently showed conditioned cardiac responses to weak electric fields applied perpendicular but not parallel to their bodies. In fields with a power density of 0.11 × 10 −3 pW/cm 3 , 6...
