FIELD: industrial fishing. SUBSTANCE: TV method of gaging hydroacoustic equipment system involves getting strictly synchronic information from one and the same volume of water by proper positioning video camera and acoustic antenna. Novelty is positioning hydroacoustic antenna between stereopair of stereo TV camera on common carrier and introduction of unit for synchronization of measuring of parameters of echosignals and density of fish mass on video image. Device has fathometer, echo indicator, stereo TV camera, video signal receiver, device of registration and processing acoustic and video information and measurement synchronization unit. EFFECT: enhanced searching efficiency. 2 cl, 3 dwg
