Russian scientists from Saint Petersburg have developed electronic lure for fish.
      
      The device looks like a small cylinder, which generates four types of signals. First of them – flashing light – attracts most curious fishes. Two other signals - vibration and weak electromagnetic impulses – affect fishes’ lateral line, telling them that several small fishes are already eating something very tasty. The last signal generates sounds of particular frequency, which was proved to attract fish.
      
      Electronic lure needs only several minutes to attract fish – you throw it to the water and then start fishing several m away from it. The device works on the batteries, which are enough for 300 hours of operation.
