Method for determination of trawl catch efficiency Method implies use of hydroacoustic echo-ranging device to determine amount of fish in front of trawl. Hydroacoustic echo-ranging device may be installed at one and/or both trawl boards. Echo ranging of target stocks in the space between trawl boards and trawl wings is carried out either from one board towards the other board or from both boards alternately towards one another. Sound impulses are emitted simultaneously or alternately. Then number of caught fish is divided by total number of fish in front of trawl to determine catch efficiency. |

Self-filling drinker comprises a frame with a drinking bowl in it, a cover with watering cups, a feeding pipe with a valve-and-float mechanism and a heating unit. The drinking bowl and water heater are connected to each other by horizontal branch pipes aligned with respect to the watering cups; perforated branch pipes are mounted in the middle part of the drinking bowl. The perforated branch pipes are inclined at an angle ϕ 3°...10° to the vertical axis of the feeding pipe and are vertically perforated with the holes being sloped at an angle α 40°...60° to the axis of the branch pipe in the drinking bowl. |

Tackle consists of an impounding part which includes a harvesting cloth and a net bag, which are made of water-permeable material, a top rope, a footrope the middle part of which is horizontal and conjugated with vertical end sections, baffles and lead weights. Tackle is provided with a vertical symmetry axis, and height of the harvesting cloth exceeds the height of the net bag mouth. Harvesting cloth is equipped with a load-bearing frame which includes at least one horizontal ledger and at least two vertical ledgers. Lower edge of the net bag mouth coincides with horizontal ledger positioned along upper rope. Ends of that rope are connected with lower rope, above its horizontal section, and ends of vertical ropes are connected with lower angles of the net bag mouth and the appropriate extreme points of horizontal section of lower rope. Sector of the harvesting cloth, which is located between horizontal rope and vertical rope corresponding to it, is made in the form of a right triangle. |

Device preventing fish from leaving trawl Device used for preventing fish from leaving the trawl consists of equal groups of acoustic-and-optic emitters of sound and light pulse signals, and echo-sounding fish control sensors in the trawl cross sections, which are discretely located along the trawl envelope from its mouth to the trawl bag. Echo-sounding sensors are installed after the appropriate acoustic-pulse emitters relative to trawl mouth, and acoustic-optic emitters are made so that they can form acoustic and optic areas directed at an angle to longitudinal trawl axis in the direction of trawl bag. |

Squid fishery method and device for its implementation Method implies concentrating the fishery targets simultaneously by light and sound; sound signals are sonar signals imitating signals of physostomous fish (pilchards, anchovies, smelts etc.) on which squids are feeding. Additionally squid visual and auditory receptors are affected by generating moving air bubbles and moving bionoise field imitating horizontal and vertical moving of fish signals in the centreline plane under the ship hull. Additionally a bubble screen is produced under the ship hull to absorb partially energy of hydroacoustic signals generated by the ship hull. Device for the method implementation comprises compressed air source with control unit at the outlet, pneumatic fish signal emitters sequentially connected by flexible pipes, return valves and receivers with the volume exceeding the previous one. The receivers are fitted with flexible cases and made of elastic material; each receiver is equipped with a sinker with the weight exceeding the previous one. Compressed air source with control unit are placed on the ship and pneumatic fish signal emitters are placed under the ship hull in the centreline plane. |

Device for fishing of young fish Device contains waterborne vehicle, traps representing a net of the cone form and capacity for catch concentration. It additionally contains arm-frame, fixed on a snout of the waterborne vehicle, traps are additionally equipped with a zip fastener, anchor wire and spacing rings, first of them are equally on the exterior part of the net within 1 metre, and next-to-last and the last one on distance of 15-20 cm. Traps are located along boards of the waterborne vehicle, and front part of the trap is attached to the arm-frame, and back part to the spacing ring which is fixed by an anchor wire to the back wall in capacity for catch concentration. The capacity for catch concentration is executed in the form of a storage box with a firm bottom which is rigidly fixed on an aft end of the waterborne vehicle. The length of the storage box is 50-60 cm longer than a boat stern, the front side of the storage box has apertures for its fastening to the stern of the waterborne vehicle and two apertures for fastening a back part of a trap to them. The back side of the storage box contains a window tightened from the interior side with seine netting with cell of 3 mm and two loops for fastening of anchor wire. The top part is executed in the form of a frame fitted of 10 mm with the seine netting. |
