Abstract : Possible effects of the proposed Sanguine communication system on American eels (Anguilla rostrata) and Atlantic salmon (Salmo salar) were investigated in three ways. Conditioned cardiac deceleration techniques demonstrated that both species are marginally sensitive to Sanguine level ELF (60 - 75 Hz) electric fields (0.007 - 0.70 V/m) but not to magnetic field (0.5 gauss). Locomotor activity levels or diel patterns of the fishes were not affected by alternating 24 hr periods of exposure and nonexposure to the ELF electric or magnetic fields. Activity rhythms were not entrained (synchronized) by one-hr exposures every 23 hr to ELF electric or magnetic fields. It is concluded that while at least these two species can probably perceive Sanguine electromagnetic radiation, their normal behavior is unlikely to be affected by such fields.
