Lifting trap. RU patent 2442326. |
|
FIELD: commercial fishery. SUBSTANCE: invention refers to commercial fishery and can be used for hauling of fish and sea invertebrates that positively respond to light. The technical result of the invention is a possibility to open a lifting trap in horizontal and vertical directions that provides a considerable enlargement of the hauled amount. The lifting trap includes netting, a chafer, spacer assemblies, devices used for control of opening and closing of the trap, a compressed air source. The spacer assemblies are linked with the netting so that they cab fold up during dipping and lifting of the trap. They are radially located in the trap mouth. The compressed air source communicates with the ambient environment and with the spacer assemblies. One end of the netting is attached to the mouth ring of the netting cone. Another one - to the flexible pneumatic ring. Between them the hard rods are installed. Due to compressed air supply to the pneumatic ring the chafer rises at the angle of 45° in relation to the mouth ring of the netting cone. EFFECT: possibility to open a lifting trap in horizontal and vertical directions that provides a considerable enlargement of the hauled amount. 1 dwg, 4 dwg

Procedure of arrangement of fishing tackle under ice and facility for this procedure (versions) / 2358425 Invention refers to industrial fishery, particularly to technical facilities for ice fishing. The procedure consists in making two holes at a distance approximately equal to the length of the fishing net; a fisherman lowers a self-propelled underwater tackle by means of a gripping appliance into the first starting hole into water under ice; a priming halyard fishing line is secured to the body of the self-propelled underwater tackle. A bitter end of the halyard is left on ice surface. Required direction of motion of the underwater tackle is set; the tackle is transferred by means of its propulsive arrangement under ice in preset direction of fishing net placing. At the end of process of transfer of the underwater tackle the second - finish hole is made. The second fisherman, who follows underwater tackle movement over the ice, continuously determines location of the tackle by listening to a device receiving emitted signals. When the underwater tackle reaches distance approximately equal to length of the fishing net, the first fisherman stops motion of the tackle by pulling the fishing line through the first hole; and the second hole is made in front along run of motion. Further the first fisherman lowers the fishing line till the underwater tackle appears in the second hole; here the second fisherman pulls it out with the gripping appliance on ice surface together with the fishing line, which has been drawn in this way between two holes. Upon following the underwater tackle signal location is performed on base of implementation of inductive coupling of the receiving device of the second fisherman and a transmitting device of the underwater tackle. The assembly of the facility consists of the gripping appliance of the underwater tackle and the underwater tackle proper with the fishing net fastened to its body, also of a screw propeller with an electric motor connected to it, of pressure tight installed switch and of electric power source, the output of which is connected to the output of the switch. Additionally a direction finder is incorporated into the assembly of the facility; the direction finder contains a receiving device with a receiving aerial connected to it, a sound indicator and a power source, the output of which via the switch is connected to the feed circuit of the receiving device, while the output of the receiving device is connected to the sound indicator. The underwater tackle additionally contains a transmitting device with a transmitting aerial connected to it and a pulse generator, the output of which is connected to the input of the transmitting device; the electric motor, feed circuits of the transmitting device and the pulse generator are connected to the second output of the switch. |
Method for controlling sea mammal behavior in fishing / 2248008 Method involves building and emitting information and energy sonar signals for controlling sea mammal behavior (including sea mammals having no natural predators) when catching fish in great volume of aquatic medium. The control actions are done in effective and short-term manner in frequency bandwidth restricted with frequency bandwidth being maximum sensitivity to fishes selected as fishing object. The information signals are built in unit for producing information signals in the channel for producing and emitting information signals being like sonar signals emitted by selected fishing equipment, fishing-boat body, systems and mechanisms when moving to fishing area or setting fishing gears. At the same time, several autonomous marine systems are installed and set in operation far from fishing area in water column at different horizons by switching on electric current. Light emission signals are sent at the same time according to program executed by the unit for producing and amplifying information signals. The sonar signals and light signals have an effect upon sea mammals and modify their behavior characteristics. |
