Method of fishing and catching marine invertebrates / 2406300 Invention may be used in the fishery of aquatic organisms positively reacting to light. Method of catching fish and marine invertebrates is to place on the perimetre of the boat of light sources parallel to the water surface for at least two levels with the possibility of rotation about the vertical and/or one of the horizontal axis and/or towards their longitudinal axis, at that the power of light sources placed on the lower level is lower than the power of light sources located on the upper level. Concentration of catch is carried out by displacement of commercial peak of the spectral characteristic of light sources located on the lower level, towards the red light and/or their alternate turning-off towards the light sources located above the gear. Preferably, the light sources of the upper level with a capacity of up to 5 kW are placed above the deck at the height of the upper tier of ship masts. At the lower level the lamps are used with capacity from 0.5 to 1.5 kW. Upon completion of the concentration with the well-known techniques the object of fishing is captured, the gear is raised, and the catch is notched. |
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. |

Method of manufacture of float for deep-water fishing gear and float manufactured by such method / 2251265 Proposed method of manufacture of float for deep-water fishing gear comes to its manufacture of material of uniformly closed porous structure and small specific weight in form of one or more preliminarily prepared blanks. First blanks in form of cylinders or prisms with through inner longitudinal hole along central axis are made from material and then each blank is subjected to preliminary stress by compressing to form float member. If float is made up several members, the latter are assembled and connected to each other, and then surfaces are leveled up to make float streamlined without sharp edges and longitudinal hole is machined, and in 20-30 days after machining, additional compacting-hardening is carried out by lowering the float starting from depth of 200 m with gradual increase of depth of immersion. Preliminary compression of blanks can be done by uniformly compacting porous structure with decrease of initial sizes of blanks till setting of material is stopped. In case of single-member float, face at angle of 45° can be removed from both sides of end face surface of blank before preliminary compression. Connection of members preliminarily stressed by compression can be made non-split. Non-split connection of preliminarily stressed blanks can be done by gluing. Machining of longitudinal hole can be done by short time power action in direction to center of float along central line from both end faces. |
