Method for fishing in process of vertical fish migration

FIELD: agriculture.

SUBSTANCE: 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.

EFFECT: invention makes it possible to remotely many times lift a passive fishing tool in accordance with change of a horisation of main fish mass location.

The invention relates to the field of fisheries - fishing passive fishing gear (GENDER): networks, circles, etc. in the course of their vertical migration (e.g., diurnal migration and others), as well as to the field of acoustics, and in particular, to the transmission of underwater sonar coded control signals.

The problem is solved by the invention is to increase the productivity and efficiency of fishing gear, the reduction of labor costs on an unlimited range of fishing with the expansion of the scope while ensuring environmental safety of fishing by remote control process is repeated at least two times, and uniform - synchronously on both sides, lift the FLOOR at a new depth, a certain hydroacoustic method according to fish tools: sonar, echo sounder, etc. or otherwise - according to many years of daily observations in the area of fishing and other, i.e. at a depth corresponding to the current horizon of finding fish in their vertical (e.g.daily etc.) migration: the bottom layer during the day (from 10:00 to 16:00), deep-layer - evening twilight (from 16:00 to 22:00), the near-surface layer at night (from 22:00 till 04:00) etc.

There is a method of catching fish, consisting of a horizontal installation of the FLOOR (e.g., network) in a given area of operation and to a predetermined depth is at, some hydroacoustic method according to fish tools (sonar, and others), or otherwise - according to observations in the area of fishing gear, ingestion of fish in the holding area action FLOOR and hold fish in it - they get stuck in the mesh, entanglement in Satnam denser and others, lifting FLOOR to the sea surface and the extraction of fish [1, 2].

The disadvantages of this method are:

1. The low efficiency of fishing because of the impossibility of catching fish in their vertical (e.g., daily) migration.

2. The inability remote lifting FLOOR to the surface after the process of fishing.

3. The inability of fishing in conditions of strong competition, the fishermen at the developed sea and floating ice, intensive navigation and other

There is a method of fishing marine biological objects (e.g., squid), lies in the vertical installation of the FLOOR (for example, vertical pelagic stage) in the specified area of fishing, some hydroacoustic method according to fish tools (sonar, and others), or otherwise - according to observations in the area of fisheries, the hit object of fishing in the zone of the FLOOR and hold the object of fishing - the ingestion of hooks with bait, lifting FLOOR to the sea surface and extracting object of fishing[1, 2, 3].

To the N. is the drawbacks of this method are:

1. Low efficiency due to catch marine biological objects in a small volume of water.

2. The inability remote lifting FLOOR to the surface after the process of fishing.

3. The inability of fishing in conditions of strong competition, the fishermen at the developed sea and floating ice, intensive navigation and other

The closest to the technical nature of the claimed is a method of catching fish in the process of vertical migration, selected as the prototype method, which consists in forming a horizontal manner from one or more networks and its installation in the formation of the vertical order of the one or more networks and its installation, piping horizontal and vertical orders of magnitude with a flexible coupling and combine them into a passive fishing gear (FLOOR)set in a given body of water determined in advance hydroacoustic method according to fish funds, or otherwise - according to observations in the area of fishing and other, ingestion of fish in the holding area action FLOOR and holding fish in it - they get stuck in the mesh and entanglement in Satnam tightly, lifting FLOOR to the sea surface and the extraction of fish [4].

The disadvantages of the prototype method are:

1. Lack of productivity (efficiency of fishing) fishing due to the inability of the CDF is planned taking into account the vertical migration of fish in the area.

2. Insufficient efficiency of fishing due to the use of a large number of horizontal and vertical networks, inability remote lifting FLOOR to the sea surface after the process of catching fish and other

3. High labor costs due to the use of a large number of horizontal and vertical networks and other

4. A limited range of fisheries - because of the impossibility of fishing under a floating ice, etc.

5. Limited scope - due to the inability of fishing in the developed sea state, active confrontation competitors and poachers, intensive shipping, etc.

6. The inability of emergency lifting FLOOR after separation (wind, excitement, passing ships, unfair competition and other) marker buoys on the surface and others

The problem is solved by the invention is to develop a method free from the above disadvantages.

The technical result of the proposed method is productive and operational catch of fish with the minimum of labour on an unlimited range of fishing with the expansion of the scope while ensuring environmental safety catch.

This objective is achieved in that in the known method of catching fish in the process of vertical migration, which consists in formirovaniyabrenda order of one or more networks FLOOR, its installation in a given body of water defined by hydroacoustic method according to fish funds, or otherwise - according to observations in the area of fishing and other, ingestion of fish in the holding area action FLOOR and holding fish in it (stuck in the mesh and entanglement in Satnam canvas), raising the FLOOR to the sea surface and the extraction of fish initial production FLOOR exercise in the lower part of the specified water - on the horizon, finding the main mass of the fish at this time of day - 1...1,5 height network, proactively; additionally, before each subsequent change of the horizon (reduced depth) finding the FLOOR, in series form, reinforce and towards the FLOOR emit sonar encoded synchronization signals F_C- to ensure the subsequent synchronous operation mechanical locks NPM or PTO, and hydroacoustic coded control signals F_iwork theorm or VPM - for simultaneous actuation mechanical locks and release adequate amounts of vertical desktop file; additionally carry out the first rise on the first FLOOR hydroacoustic encoded control signal F₁transmitted with CPF, after raising the main body of the fish on CH is Bina, exceed 1-1,5 height network FLOOR, changing depth FLOOR 2-3 heights of its network (proactive, equal to 1-1,5 heights network - synchronous operation of the lower mechanical locks two of the NPM and simultaneous release of the first stocks vertical desktop file that was previously at the bottom of the container; a second lifting FLOOR exercise on the second hydroacoustic encoded control signal F₂transmitted with CPF, after raising the main body of the fish at a depth greater than 1-1,5 height network FLOOR, changing depth FLOOR 1.5-2 height of its network - synchronous operation of the upper mechanical locks NPM and simultaneous release of the second vertical stocks working file that was previously in secondary containers; the third rise of FLOOR is done according to the third hydroacoustic encoded control signal F₃transmitted with CPF, after raising the main body of the fish at a depth greater than 1.5-2 height network FLOOR, changing depth FLOOR 1-1,5 height of its network - synchronous operation mechanical locks off and synchronous release is necessary (but not all) of the third vertical stocks working file that was previously in the upper containers and others stocks vertical desktop file for not less than 10% (to account for the flow near the mouth of the hall FLOOR) exceed the depth of the area of the installation FLOOR and placed in the respective upper containers in a certain way (laid Bay rings of the English stranglehold" - marine sites, easily dismissed when unwinding the Bay during ascent FLOOR) ensuring, thus, the possibility of emergency (due to breakage of the signal buoys that are previously on the surface and marking the boundaries of GENDER and other) lifting the FLOOR with any depth (including, from the bottom) on the surface of the sea; additionally use the backup - time management of all NPM and off through the use of each of them identical to each other timers, providing actuation of their respective mechanical locks at a set time in advance; in addition, on the surface of the sea mark the limits of the previously exposed FLOOR when using two identical marker buoys and landmarks with flashing beacons installed on both sides of the FLOOR and connected to the upper parts of the respective PTO by a thin vertical line, exclusive, due to the small burst of effort, the possibility of rise in the sea surface unfair competition FLOOR caught fish.

Figure 1 and figure 2 presents a structural diagram of a device that implements a method of catching fish in their vertical migration. While figure 1 illustrates a structural diagram of the device primarily to the General principle of the developed method; figure 2 illustrates the structure of the Naya diagram of the device primarily to the upper and lower remotely controlled (by the hydroacoustic channel) underwater modules.

Figure 3 illustrates the appearance of two (with two mechanical locks) lower subsea module (NPM), which has a negative buoyancy. Figure 4 illustrates the appearance of single-top subsea module (VPM), which has a positive buoyancy, and command module (KM).

Figure 5 in the form of corresponding histograms illustrates the average catches of fish in finding the FLOOR on one (histogram I), two (histogram II) and three (histogram III) horizons in the process of implementation of the developed method of catching fish in their vertical migration.

The device comprises (figure 1 and figure 2): fishing (1) a vessel (CPF), FLOOR (2) and the gear (OL) - fish (3). At CPF (1) are: device (4) arm-sample FLOOR (2), MILES (5), navigation radar (6) station (NRS) with an antenna (7). Thus KM (5) comprises sequentially electrically connected blocks: the formation of (8), gain (9) and radiation (10) hydroacoustic coded control signals F_i(F₁F₂and F₃and hydroacoustic coded synchronization signals F_C.

In turn, PAUL (2) contains: horizontal working FAL (11), negatively buoyant (backbone)to which is attached a horizontal network (12), vertical desktop file (13), positively with the th buoyancy (buira), located on two sides of the horizontal network (12) and the lower end attached to the corresponding (one of two) anchor (14), as well as having the necessary supplies vertical desktop file, placed in two (from different sides of the horizontal network) identical to each other the bottom (near the bottom) of the container (15), identical to each other averages (horizontal network) of the container (16) and identical upper (above the horizontal network) containers (17). However, the corresponding (located on different sides of the horizontal network (12) at the same distance from the bottom of the lower container (15) and medium-sized containers (16) has two identical NPM (18), and two identical VPM (19) are located above the horizontal network (12) and above the top of the container (17). Fishing gear (2) also contains: a thin vertical line (20)having positive buoyancy and attached to the lower end of the corresponding (one of two) VPM (19), and the upper end to the corresponding (one of two) marker buoy (21). In turn each of the two marker buoys (21) using a thin horizontal line (22)connected to the appropriate milestone (23), on the upper end of which is flashing beacon (24).

Each of the two NPM (18) and each of the two VPM (19) contains identical blocks: receive (25) and Wuxi is possible (26) hydroacoustic coded synchronization signals at a frequency F _Cand hydroacoustic coded control signals at frequencies F₁F₂and F₃identical to each other electromagnets (30) and mechanical locks (31), each of which is in the initial position of the inserted identical to each other connective rings (32)are identical to each other vysokoopasnye batteries (33) and timers (34).

Each of the two NPM (18) contains identical to each other decoders (27) and (28) hydroacoustic coded synchronization signals at a frequency F_Cand hydroacoustic coded control signals at frequencies F₁and F₂respectively, and each of the two VPM (19) contains identical to each other decoders (29) hydroacoustic coded synchronization signals at a frequency F_Cand hydroacoustic coded control signals at a frequency F₃.

Thus the output of each of viscoelastic batteries (33) EDL (18) and VPM (19) is connected with the respective gain blocks (26), decoders: (27), (28) and (29), magnets (30) and timers (34). In this case each of the two VPM (19) has a bright color and reflective coating for efficient visual search, as well as special radar coverage for effective technical search (effective reflection signals) using the NRS (6) CPF (1).

The way realize the t in the following way (figure 1, 2).

In the model scheme: CPF (2) leaves in the morning from the database, and should be in the area of fishing in relation to coastal fisheries, or leaves in the morning in a given square area of fishing in relation to ocean fisheries.

In the specified area of the catch of fish - OL (3) hydroacoustic method according to fish-finding sonar or echo sounder CPF (1) NRS (6) and the antenna (7), or otherwise - according to observations, etc. defines the characteristic depth finding OL (3) at any given time of the day (during vertical migration of fish).

As you know, CPF (1) can serve not one, but several - at least two, POS (2), therefore, depending on the fishing situation, anticipated the possibility of changes in accordance with the vertical migration of fish, horizon finding this FLOOR (2), as in sonar encoded control signal F_itransmitted using KM (5) with CPF (1), and set a predetermined time (for example, 16:00, 22:00 and 04:00 in the initial production FLOOR 10:00) - with appropriate timers (34). At this time, the control channel is back sonar control channel.

Then with CPF (1) in the daytime, when OL (3) is in the bottom layers of water, to carry out an initial staging GENDER (2) in the lower part specified in the underwater space - on the horizon, finding the main mass of the fish at this time of day: 1-1,5 height of a horizontal network (12) SEX (2) by pre-emption. While on the surface of the sea mark the limits of the exposed FLOOR (2) using two identical marker buoys (21) and joined them with a thin horizontal line (22), milestones (23) with flashing beacons (24)installed on both sides of the FLOOR (2) and connected to the upper parts of the respective VPM (19) by a thin vertical line (20), excluding, due to the small burst of effort, the possibility of rise in the sea surface unfair competition FLOOR (2), including those already caught fish.

With developed (more than 3-4 points) rough seas marker buoys (21), due to a small linear dimensions and sail, more securely held on the surface of the sea than a typical working buoys, with a much larger linear dimensions and windage. For the same reason, to work more effectively anchors (14), which, ultimately, to more securely hold in the water column horizontal network (12) and SEX (2), in General. When attempting unfair competitors and poachers to raise to the surface of the previously installed FLOOR (2), will break the corresponding thin vertical line (20)having a small breaking strength, and SEX with fish OS is anetta on the spot. The same thing will happen if the sea surface floating ice, passing ships and other

In the process of movement in the horizontal plane, with a gradual rise to the surface - feeding and so on, concentrations of fish - OL (2) falls within the enclosure area - preserving actions of PAUL (2), and the draught of the fishes in it: jam fish in the mesh and their entanglement in Satnam the canvas.

However, after some time in the natural process of daily migration of the bulk concentrations of fish out of the zone enclosure rises above a horizontal network (12) GENDER (2) and continues movement in the horizontal plane, with a gradual rise to the surface - foraging.

At the estimated time of lifting the FLOOR (2) to a new horizon, or based on fishing conditions, CPF (1) suitable in the area with the FLOOR (2), without scaring OL (3) its low frequency underwater acoustic noise operating mechanisms and others) and hydrodynamic (noises wrap water body CPF and other) noise and using fish sonar or echo sounder determines the horizon of the current location OL (3) in the water column, including the FLOOR (2).

With CPF (1), determining that the main concentrations of fish - OL (3) up to 1-1,5 height above the horizontal network (12), with KM (5) give hydroacoustic encrypted management team to operate the lower milling is a mini-castles (31) NPM (18) and the release of reserves vertical desktop file of the identical lower container (15), located on two sides of the horizontal network (12) and below it.

For this CPF (1) falls in the drift, and with its lower side unit (10) KM (5) to a depth of at least (to avoid shielding housing CPF) 5-10 m below keel CPF (1). Then, sequentially electrically connected blocks (8) and (9), shall set and increased to the required level (determined by the distance to the NPM FLOOR) hydroacoustic encoded (to prevent accidental actuation signals from natural and anthropogenic origin, and to exclude selection signals unfair competition) of the synchronization signal F_Cand its subsequent directed towards NPM (18) radiation, using block (10) KM (5).

In identical blocks of admission (25) and the gain (26), and identical to each other: the decoders (27) for the bottom of the locks of each of the two NPM (18), decoders (28) to the top of the locks of each of the two NPM (18), decoders (29) - locks for each of the two VPM (19), perform the reception, amplification and decoding (comparison predetermined synchronization code with the received code synchronization) received hydroacoustic coded synchronization signals F_C. In the case of the established and accepted codes of electronic blocks of all NPM (18) and VPM (19) are synchronized and transferred to the projection mode is of the reception of the corresponding sonar encoded control signal. Synchronization of all subsea modules is done so that in case of force majeure, it was possible to immediately cease fishing and to raise the FLOOR (2) on the surface of the sea, or on the basis of the fishery: fish abruptly went to the surface and so on, to provide synchronous lifting FLOOR (2) 2-3 height of a horizontal network (12), and 4-6 heights horizontal network (12), etc.

Then sequentially electrically connected blocks (8) and (9) carry out recruitment and increased to the required level hydroacoustic encoded control signal F₁and its subsequent directed towards NPM (18) radiation, using block (10) KM (5).

In identical blocks of admission (25), gain (26) and decoders (27) carry out the reception, amplification and decoding the received sonar coded control signals F₁. If a match is established and adopted codes, the control signals synchronously fed to the electromagnets (30), which in turn synchronously open lower mechanical locks (31) NPM (18). Under the action of positive buoyancy due to the VPM (19), from mechanical locks (31) synchronously released previously inserted in them connecting ring (32). Then from the bottom to be identical containers (15) synchronously leave adequate supplies vertical is working halyard (13) and horizontal network (12) synchronous rises to 2-3 of their height and occupies a new horizon.

In the process of movement in the horizontal plane, with a gradual rise (due to the natural diurnal migration) to the surface - feeding and so on, concentrations of fish - OL (2) enters a new zone of the harvest FLOOR (2) and the new (re) fishing: the jam fish in the mesh and their entanglement in Satnam the canvas. However, after some time in the natural process of daily migration of the bulk concentrations of fish out of the new zone enclosure rises above a horizontal network (12) GENDER (2) and continues movement in the horizontal plane, with a gradual rise to the surface - foraging.

By analogy with the above, with CPF (1), determining that the main concentrations of fish - OL (3) up to 1-1,5 height of a horizontal network (12), with KM (5) give hydroacoustic encrypted management team to operate the upper mechanical locks (31) NPM (18) and the release of reserves vertical desktop file of the identical medium containers (16), located on two sides of the horizontal network (12) and under it. For this CPF (1) again lies in the drift and with its lower side unit (10) KM (5) to a depth of at least 5-10 m below keel CPF (1). Then, sequentially electrically connected blocks (8) and (9), shall set and increased to the required level hydroacoustic encoded synchronization signal F Cand its subsequent directed towards NPM (18) radiation, using block (10) KM (5).

In identical blocks of admission (25) and the gain (26), and identical to each other: the decoders (28) to the top of the locks of each of the two NPM (18) and decoders (29) - locks for each of the two VPM (19), perform the reception, amplification and decoding the received sonar coded synchronization signals F_C. In the case of the established and accepted code the appropriate e-blocks all NPM (18) and all electronic components VPM (19) are synchronized and transferred to the standby mode receive corresponding acoustic encoded control signal. Then sequentially electrically connected blocks (8) and (9) carry out recruitment and increased to the required level hydroacoustic encoded control signal F₂and its follow - directed towards NPM (18) radiation, using block (10) KM (5).

In identical blocks of admission (25), gain (26) and decoders (28) carry out the reception, amplification and decoding the received sonar coded control signals F₂. In the case of the established and accepted code the control signals synchronously fed to the electromagnets (30), which in turn synchronously open top m is a mechanical locks (31) NPM (18). Under the action of positive buoyancy due to the VPM (19), from mechanical locks (31) synchronously released previously inserted in them connecting ring (32). Then from medium to be identical containers (16) synchronous leave adequate supplies vertical desktop file (13), and a horizontal network (12) synchronous rises to 2-3 of their height and occupies a new horizon.

In the process of movement in the horizontal plane, with a gradual rise (due to the natural diurnal migration) to the surface - feeding and so on, concentrations of fish - OL (2) enters the second new area of harvest FLOOR (2) and the new (third) catch of fish in it: jam fish in the mesh and their entanglement in Satnam the canvas. However, after some time in the natural process of daily migration of the bulk concentrations of fish out of the second new zone enclosure rises above a horizontal network (12) GENDER (2) and continues movement in the horizontal plane, with a gradual rise to the surface - foraging.

By analogy with the above, with CPF (1), determining that the main concentrations of fish - OL (3) up to 1-1,5 height of a horizontal network (12), with KM (5) give hydroacoustic encrypted management team to operate mechanical locks (31) VPM (19) and the release of reserves vertical desktop file ID from stichnyh each other top containers (17), located on two sides of the horizontal network (12) and above it. For this CPF (1) again lies in the drift and with its lower side unit (10) KM (5) to a depth of at least 5-10 m below keel CPF (1). Then, sequentially electrically connected blocks (8) and (9), shall set and increased to the required level hydroacoustic encoded synchronization signal F_Cand its subsequent directed towards VPM (19) radiation, using block (10) KM (5).

In identical blocks of admission (25) and the gain (26), and identical to each other decoders (29) of each of the two VPM (19), perform the reception, amplification and decoding the received sonar coded synchronization signals F_C. If a match is established and adopted codes, e-blocks all VPM (19) are synchronized and transferred to the standby mode receive corresponding acoustic encoded control signal. Then sequentially electrically connected blocks (8) and (9) carry out recruitment and increased to the required level hydroacoustic encoded control signal F₃and its subsequent directed towards VPM (19) radiation, using block (10) KM (5).

In identical blocks of admission (25), gain (26) and decoders (29) carry out the reception, amplification and decoding rinyateh hydroacoustic coded control signals F ₃. In the case of the established and accepted code the control signals synchronously fed to the electromagnets (30), which in turn synchronously open mechanical locks (31) VPM (19). Under the action of positive buoyancy due to the VPM (19), from mechanical locks (31) synchronously released previously inserted in them connecting ring (32). Then from the top to be identical containers (17) synchronously leave adequate supplies vertical desktop file (13), and a horizontal network (12) synchronous rises to 2-3 of their height and occupies the third new horizon.

In the process of movement in the horizontal plane, with a gradual rise (due to the natural diurnal migration) to the surface - feeding and so on, concentrations of fish - OL (2) falls in the third new area of harvest FLOOR (2), and there is a new (fourth) the draught of the fishes in it: jam fish in the mesh and their entanglement in Satnam the canvas.

As previously noted, in the case of using information on typical horizons find the fish according to many years of daily observations, or inability, for any reason, the approach CPF (1) by SEX (2), signal to actuate the respective electromagnets (30) and castles (31) NPM (18) and VPM (19) comes from the respective timers (34). While using the appropriate viscoelastic item is tori (33) is the power amplifier units (26), the decoders: (27), (28) and (29)and the magnets (30) and timers (34).

After the process of catching fish data FLOOR (2) to one (for example, to the West when the East wind) tip: marker buoy (21)which is connected with a thin horizontal line (22) with the appropriate milestone (23), on the upper end of which is flashing beacon (24) - if present on the surface of the sea, or in the settlement point in the event of breakage of the marker buoy (21) with milestone (23), the ascent of the corresponding MPI (19), the body of which has a bright color and reflective coating (for the best visual search), and special radar coverage (for best technical search), suitable CPF (1) NRS (6).

Once detected (visually or technically) emerges at the surface of the sea VPM (19) carry out his ascent to the CPF Board (1), and then, by means of vertical desktop file (13) and the device (4) arm-sample FLOOR (2), taking on Board CPF (1) the FLOOR (2) with fish - OL (3). Then FLOOR (2) to prepare for a new production, for which: each of the NRM (18) and each of the VPM (19) is switched to standby mode (standby reception hydroacoustic coded synchronization signals and control) by turning 90° clockwise inserted into corresponding mechanical locks (31) of the connecting rings (32)and apase vertical desktop file in a certain way (excluding tangling with automatic unwinding) are accommodated in the respective bottom (15), medium (16) and upper (17) containers.

When you do this:

1. The high productivity of the fishing reach due to the fact that:

the original production FLOOR exercise, using data from fish-finding sonar (sonar), or long-term observations in the lower part of the specified water - on the horizon, finding the main mass of the fish at this time of day, with a small pre-emption;

- produce multiple depth change of location of the FLOOR, using data pre-fish-finding sonar (sonar), or long-term observations on the horizon, finding the main mass of the fish at this time of day, with a little proactive, and others;

- used backup (temporary) control of all NPM and off through the use of each of them identical timers;

- safeguard the FLOOR from being stolen by unscrupulous competitors by connecting VPM and marker buoys thin vertical line, exclusive, due to the small burst of effort, lifting with it the surface of the sea FLOOR, etc;

2. High efficiency gear reach due to the fact that:

with CPF carry out the production of only one horizontal network, and then repeatedly, either remotely or at a specified time, raise it to a new depth in accordance with the change in g is of rizona find the majority of fish OL in the process of vertical migration;

one CPF can simultaneously serve several FLOORS. For example, one FLOOR be controlled remotely by the hydroacoustic channel, and the other (the other) HALF - temporary-channel etc.

3. Low labor costs provide due to the fact that:

- deck team is encouraged to work 2 times - one setting and fetching the FLOOR, and then repeatedly, either remotely or at a specified time, the FLOOR is raised to a new depth in accordance with the changing horizon of finding the main mass of the fish, without the participation of the deck crew.

In other words, instead of 4 productions-FLOOR samples at different depths provide only one production sample GENDER:

one CPF, with the same effort of the deck crew, can simultaneously serve four FLOORS. For example, one FLOOR be controlled remotely by the hydroacoustic channel, and three temporary channel, etc.

4. The extension of the area of fisheries reach due to the fact that:

- provide, due to the presence of channel automatic emergency search and rise to the surface of the sea FLOOR, possibility of fishing in areas with hard ground, when the hooks anchors and subsequent breakage vertical working files usually lose the FLOOR and refuse from fishing in productive areas;

- provide, because hydro is justiceship coded control signals, the possibility of fishing in terms of floating ice, when the FLOOR immediately pick up on the sea surface during the formation (due to wind, current, etc. corresponding hole on it, etc.;

5. Extending the scope of application of reach due to the fact that:

- provide, through hydroacoustic coded control signals, the possibility of fishing in the developed sea state;

- provide, through hydroacoustic coded control signals, the possibility of fishing with intensive shipping;

- provide, through hydroacoustic coded control signals, fishing and delivery of products (without lifting of the FLOOR) with the active opposition of competitors and poachers (usually in a very productive fishing area), etc.

6. Ensuring environmental safety of fishing (harvesting) reach due to the fact that:

- provide, through hydroacoustic coded control signals, the possibility of emergency after separation (wind, excitement, passing ships and other) marker buoys, floating FLOOR to the surface;

- provide, thanks to a temporary control channel, the automatic surfacing at the specified time on the FLOOR surface, etc.

Distinctive features of the prototype characteristics of the proposed method are:

1. The original formulation of P Is L is carried out in the lower part of the specified water - on the horizon, finding the main mass of the fish at this time of day - 1...1,5 height network proactively.

2. Before each subsequent change of horizon finding FLOOR emit sonar encoded synchronization signals F_C.

3. The first synchronous lifting FLOOR exercise at the first sonar encoded control signal F₁transmitted with CPF, after raising the main body of the fish at a depth greater than 1-1,5 height network FLOOR, changing depth FLOOR 2-3 heights of its network proactively equal to 1-1,5 heights network.

4. The second synchronous lifting FLOOR exercise on the second hydroacoustic encoded control signal F₂transmitted with CPF, after raising the main body of the fish at a depth greater than 1-1,5 height network FLOOR, changing the depth of location of the FLOOR at 1.5-2 height of their network.

5. The third synchronous lifting FLOOR exercise on the third hydroacoustic encoded control signal F₃transmitted with CPF, after raising the main body of the fish at a depth greater than 1.5-2 height network FLOOR, changing depth FLOOR 1-1,5 height of their network.

6. Emergency lifting the FLOOR with any depth (including the bottom) to the surface of conduct at any time or at any stage of the ascent, on the third hydroacoustic encoded signal to control the means F ₃transmitted with the CPF, as well as by a third stock vertical desktop file for not less than 10% (to account during installation FLOOR) greater than the depth of the area of the installation FLOOR and placed in the respective upper containers.

7. Stocks vertical desktop file in the lower, middle and upper containers stacked rings of the English stranglehold", easily dismissed when unwinding during ascent the FLOOR.

8. To change the depth of location of the FLOOR in the process of vertical migration of fish used backup (temporary) control of all NPM and off through the use of each of them is identical to the timers.

9. On the surface of the sea mark the limits of the previously exposed FLOOR using two identical small marker buoys and landmarks with flashing beacons installed on both sides of the FLOOR and connected to the upper parts of the respective VPM.

10. Safeguard the FLOOR from being stolen by unscrupulous competitors by connecting VPM and marker buoys thin vertical line, exclusive, due to the small burst of effort, lifting with it the surface of the sea FLOOR.

The presence of the distinctive features of the prototype features allows you to make a conclusion on the conformity of the proposed method the criterion of "novelty".

Analysis of izvestnyh technical solutions to detect in these distinctive characteristics have shown the following.

Signs 3, 4, 5, 6, and 10 are new and unknown use them to catch fish in their vertical migration.

Signs 2, 7 and 8 is new and unknown use them to catch fish in their vertical migration. At the same time known use: grounds 2 - in telemetry, characteristic 7 - in navigation and fishing, characteristic 8 - in Oceanography.

Signs 1 and 9 is well known in the draught of the fishes.

Thus, the presence of new significant features, in conjunction with the known, provides the appearance of the proposed solutions new properties that do not match the properties of the known technical solutions - productive (efficient) and efficiently (quickly) to catch fish in their vertical migration with minimal labor costs on an unlimited range of fishing (rocky ground, floating ice, and others) extension of scope (at the developed sea, intensive labour and others) while ensuring environmental safety (automatic search and rise to the surface from any depth, including from the bottom) fishing.

In this case, we have a new set of features and their new relationship, and not easy integration of new features and is already known, namely the operations in the proposed sequence and leads to the quality of the new effect.

This fact allows to make a conclusion on the conformity of the developed method the criterion of "substantial differences".

An example implementation of the method.

Field tests of the developed method was carried out on the fishing ground in the North Bay (Peter the Great Bay, sea of Japan) in 2001, as well as in the Republic of Korea in 2005-2007, a total of 16 productions were made FLOOR, and 48 remote changes in the depth of location of horizontal networks, and not recorded not a single case of failure of the NPM and VPM. It was also performed on 8 FLOOR productions, as well as a 24 auto - temporary control channel, remote changes in the depth of location of horizontal networks, and not recorded not a single case of failure timers NPM and VPM.

Figure 3 and figure 4 illustrates the appearance of two NPM negatively buoyant, and single-VPM, with positive buoyancy, and KM used in the process of testing the developed method of catching fish.

In table 1 in the corresponding rows and 5 is in the form of corresponding histograms, presents the average catches of fish (kg) when experimental (length 50 m, height 2.5 m) FLOOR on one (histogram I), two (histogram II) and three (histogram III) horizons in the process of implementing elaborately what about the way of catching fish in their vertical migration. Testing of the developed method was carried out in the coastal areas of the Republic of Korea on one of the fishing vessels of the company "BluWave" (Seoul).

As can be seen from table 1 and figure 5, when the experimental FLOOR at two horizons within 12 hours of its effectiveness increases ~ 350 kg (~ 70%), and when the three horizons for 18 h ~ 750 kg (~ 150%). It should be noted that when the circuit performances of the experimental FLOOR as the prototype method (one horizontal chain length of 50 m and a width of 2.5 m, and two vertical network length of 50 m and a width of 2.5 m, located at the edge of the horizontal network) catchability for 18 h 750 is g (win ~500 kg or ~66,7%), and when the model scheme of the experimental setting FLOOR as the method-analogue (one horizontal chain length of 50 m and a width of 2.5 m) catchability for 18 h amounted to 600 kg (win ~650 kg or ~108,3%). However, the implementation of the prototype method the duration of the process of setting-sampling in 4-5 times the length of the developed method and accounted for 5-6 h with the involvement of the second CPF. It should also be noted that when the sea is rough more than 2-3 points to put even experimental (shortened) PAUL was not possible. Thus, the advantages of the developed method of catching fish in their vertical migration before the method of the prototype obvious. When you do this:

1. The high productivity of the crystals was achieved due to the fact that:

the original production FLOOR was carried out using data of fish-finding sonar (sonar) or long-term observations in the lower part of the specified water - on the horizon, finding the main mass of the fish at this time of day, with a small pre-emption;

- produced multiple depth change of location of the FLOOR, using data pre-fish-finding sonar (sonar), or long-term observations on the horizon, finding the main mass of the fish at this time of day, with a little proactive, and others;

- used backup (temporary) the Board all the NPM and off through the use of each of them identical timers;

- ensured the safety of the FLOOR from being stolen by unscrupulous competitors by connecting VPM and marker buoys thin vertical line, exclusive, due to the small burst of effort, lifting with it the surface of the sea FLOOR, and others;

2. High efficiency gear was reached due to the fact that:

with CPF staged only one horizontal network, and then repeatedly, remotely or over a specified time raised it to a new depth in accordance with the changing horizon of finding the main mass of the fish - OL in the process of vertical migration;

one CPF simultaneously serve several FLOORS. For example, one FLOOR was controlled remotely by the hydroacoustic channel, and the other (the other) HALF - temporary-channel etc.

3. Low labor costs was provided by the fact that:

- deck team involved in the work 2 times - one setting and fetching the FLOOR, and then repeatedly, either remotely or at a specified time, the FLOOR was raised to a new depth in accordance with the changing horizon of finding the main mass of the fish, without the participation of the deck crew;

one CPF, with the same effort of the deck crew, could simultaneously serve four FLOORS;

4. The extension of the area of fishing was achieved due to the fact that ensured the prob is the possibility of fishing in areas with hard ground, etc.

5. The expansion of the scope was achieved due to the fact that:

- ensure the possibility of fishing in the developed (more than 3 points) the sea;

- ensure the possibility of fishing in the intensive coastal shipping;

- ensure the possibility of putting products when the FLOOR under the water, etc.

6. Ensuring environmental safety gear achieved through:

- provide the capability emergency ascent on the FLOOR surface;

- provided the ability to automatically surfacing at the specified time on the FLOOR surface, etc.
