THE ELECTROSENSOR SYSTEMS OF THE ROUND-MOUTH AND FISHES

Using the round-mouth and the fishes, the morphofunctional properties of the electrosensor systems of the ampulled electroreceptors and the mechanisms of reception of the magnetic field effects by the animals. Two types of the electrosensor systems i.e., an- and catelectrosensor systems, which have the different properties of the electroreceptor cells, the innervation and central representation, have been revealed. Both systems are adapted to the reception of the infralow-frequency electric fields. The ability of the electrosensitive fishes to react to the arising and approaching the earthquakes, cyclones, and to perceive the electric fields of the biological origin has been shown. Experimentally established has been the law of reception, not known earlier, the effects of the Earth magnetic field by the water vertebrates. The results of the work insert the principal changes in the representation about the functional assignment of the electrosensor systems, on its base the creation of the new methods of prognosing of many geophysical phenomena (tsunami, cyclones, earthquakes) and the development of the new instruments of orientation and navigation. The materials of investigations are used in the Polar Scientific Research Institute of Sea Fishery and Oceanography in the development of the selective devices of catching, have been introduced in some organization.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
