|
FIELD: commercial fishery. SUBSTANCE: method involves choosing space; setting fishing equipment; hauling-in fishing equipment and determining catching object, with vertical, bottom and vertical fishing longlines sequentially connected with one another being used as catching equipment; using buoy ropes of bottom longline as ridge for vertical longlines; attaching hooks along the entire length of bottom buoy ropes at 1.0-1.5 m pitch; determining catching objects by visible dimensional features; determining habitat horizon from formula: H=L·cos α, where H is habitat depth from water surface; L is distance from water surface to each of said hooks fixed on vertical longlines; α is angle defined between depth vertical in catching equipment setting region and buoy rope of vertical longline. EFFECT: increased precision in determining distribution of fish fauna in bathyal zone, epi-, meso- and bathypelagial zone. 2 dwg

Method for determining of trawl motion parameters and apparatus for performing the same / 2281649 Method involves providing additional signals according to deviation angles of right-hand and left-hand wires relative to diametrical plane of puller vessel and also signals according to angles of submersion of right-hand and left-hand wires into water relative to waterline plane of puller vessel, from which signals trawl motion parameter signals and puller vessel motion parameter signals are determined. Apparatus has right-hand and left-hand converters for converting angles of wire deviation from diametrical plane of puller vessel and also for converting angles of submersion of wires into water relative to waterline plane of puller vessel, with outputs thereof being outputs of apparatus by trawl motion parameters and puller vessel motion parameters. |
Trap for fish and other hydrobionts (versions) / 2266644 Four versions of traps are described, which contain netted web, rod-type carcass with rods pivotally connected with their proximate ends to central pivot hinge, and strap system for setting of netted web and lifting of trap. Strap system comprises straps secured with each other by their upper ends at securing point and connected with outer ends of rods. According to first version, strap system is further equipped with central strap, whose lower end is fixed on central pivotal means and on whose upper end is fixed guiding sleeve with straps having been passed therethrough for sliding, said straps extending from point where said straps are connected to rods outer ends for providing fast bringing thereof together and reliable holding of outer ends of rods. According to second version, straps secured with their upper ends to one another are passed for sliding through eyelets provided on outer ends of rods, and are fixed with their lower ends in the vicinity of proximate ends of rods. Netted web is set on strap branches between point of securing and eyelets, and on strap branches between eyelets and point of securing of their lower ends. Trap is therefore used as small-sized vertical bottom net. Strap system of third and fourth versions includes straps for successive connection of outer ends of rods, with netted web being set on said straps at site below said rods. According to third version, straps secured to one another with their upper ends are passed for sliding through eyelets at outer ends of rods and are successively fixed with their lower ends on ends of adjacent rods. Netted web is set on thus formed strap branches to allow netted web to be removed from carcass for extraction of fish caught. According to forth version, additional vertical netted web is set on strap branches arranged between point of securing thereof with outer ends of rods, and also on rods, said straps being connected with ends of said rods. So, one netted web serves as horizontal net and other netted web serves as vertical net to thereby increase reliability in determining of pecking and fish holding time. |

Wing net of hoop type / 2411725 Invention relates to area of industrial fishery, in particular, to devices for fishery in shallow zone. Wing net comprises net cylinder, fishing gears, stable, hoops, stakes for setting, float and light elements. Light elements are installed in area of fishing gears with supply from power thermocouples. Lower power thermocouples are arranged in area of fishing gears, and upper ones - in float joined by switching wires with lower power thermocouples of wing net. Float is arranged in the form of cylinder with insert in upper part from polished tin with reflecting parabolic surface and has shell from porous fibrous material with canopy. |
Method for fishing in process of vertical fish migration / 2480985 Invention relates to fishery. The method includes placement of a passive fishing tool at a largest depth during that time of the day, when the main mass of fish is available there. Upon daily migration of the main mass of fish the passive fishing tool is lifted. A hydroacoustic signal is emitted from a fishing vessel towards the passive fishing tool, and this signal synchronously actuates mechanical locks of underwater modules, releasing reserves of vertical working halliards, therefore depth of passive fishing tool location is reduced. Further changes of passive fishing tool location depth are carried out in a similar manner. |
