Description

  The present invention comprises a growing part for growing seafood algae such as fish, shellfish, sea cucumbers, sea urchins, seaweeds, a supporting part for supporting the growing part, a direction changer, and a fixing for mooring the supporting part. A water depth variable mooring facility for aquaculture comprising a portion, a float for pulling the support portion into the water, and a mooring line connecting the support portion and the pull float via the direction changer .

Growing parts such as cages for raising seafood algae and cages, and holders made of wire rods, strings, shells, etc. are attached to support parts made of rope etc. Although it is installed, there is a “long line type” as a conventional method for mooring a growing part and a supporting part.
In the longline type, one end side of the mooring rope is connected to both ends of the trunk rope as a support portion that is extended in the horizontal direction, and the other end side of the hoisting rope is anchored to the rope rope such as a submarine soil or an anchor. The trunk rope is installed in a configuration in which the trunk rope is supported by a required layer such as a surface layer or a middle layer mainly by a float floating in the vicinity of the water surface (hereinafter referred to as a water surface float).
The longline type is a floating longline type in which water surface floats are directly attached to the trunk rope at regular intervals and are installed on the surface layer, and suspension ropes are arranged at predetermined intervals with respect to the trunk rope, and the water surface float is placed at the upper end of the suspension rope. Is attached, and the main rope is classified into the hanging longline type, which is installed from the upper layer to the middle layer.
The floating longline type is prone to the effects of waves because the water surface float and trunk line are installed near the water surface, which may cause problems in ship navigation, and has problems in terms of maintenance and safety.
The hanging longline type is widely used for aquaculture of shellfish such as scallops and oysters, sea cucumbers, seaweeds, etc., and is hung on a suspension rope of the required length connected to a water surface float floating near the water surface at regular intervals. A method of attaching the float for adjustment to the main points of the trunk rope, attached to the trunk of the trunk rope attached to the main trunk rope as a supported support, attached with the growing part of the holding body formed with cultured baskets or wire rods at the required intervals By adjusting the buoyancy, the depth of the trunk rope and the growing part is kept almost constant.
The hanging longline type has problems due to the above structure, which are listed below.
(1) Since trunk ropes and breeding departments are installed on the basis of water surface floats, external forces such as surface waves and tides are easily transmitted to trunk trunks and breeding departments, and facilities are easily damaged or damaged by aging. The target organism may be stressed by shaking, leading to poor growth, illness, and drowning. (2) Since the water depth of the breeding section is almost fixed, it may deviate from the appropriate water temperature due to regional characteristics and water temperature fluctuations, and there are cases of poor growth, illness, drowning, and death.
(3) When desalination occurs due to red tide or rain, damage cannot be avoided due to the structure that cannot move in the depth direction or move to other places.
(4) The water surface floats, suspension lines, trunks are swung by waves and blown by tidal currents, and the depth of the breeding section changes, making it difficult to stably install in deep water depths or near the bottom of the water. It is not suitable for target organism growth that needs to be cultivated in various places, and lacks functionality and versatility.
(5) Many members are arranged near the surface layer, and it is easy to attach extraneous deposits such as shellfish and algae. Oxygen deficiency, nutrient deficiency, poor growth, drowning, and death due to deposits are likely to occur. The load of waves and tidal currents hitting the deposits is applied, and the facilities are easily lost or damaged.
(6) There are many surface floats and suspension ropes near the surface of the water, which hinders operations and ship navigation, and is prone to screw entanglements and ride-through accidents, and lacks safety and facility maintenance.
(7) When pulling up the breeding unit for cleaning the deposits, the weight of the growing unit, target organism, trunk trunk, and the tension of the ropes are added, increasing the load and requiring equipment such as a crane. Because the trunk line and the rope are tense, the work is dangerous, and the workability, labor saving and safety are lacking.
(8) Trunk a rope with a length of about three times the water depth for the purpose of securing the anchor strength of the rope rope and alleviating the point where the rope is stretched and tensioned when the trunk rope or raising part is pulled up. Since it is necessary to arrange on both sides of the rope, the occupied area of the whole facility becomes large and the effective use of the fishing ground is lacking.

In order to solve these problems (Patent Document 1), “Floating and sinking ropes can be used to suspend aquaculture rods in the northern Japan Sea type floating and sinking aquaculture facility in Hokkaido and to sink trunk ropes and cultivation rods during typhoons. “Type offshore multi-stage aquaculture” is disclosed.
(Patent Document 2) states that “the structure is one in which two floats are attached to the aquaculture body, the outside float is inhaled, and the buoyancy is adjusted by exhausting the air. A “floating and sinking aquaculture ginger for use in the open ocean” characterized in that the body of the ginger rises by injecting air is disclosed.

JP 2004-305197 A JP-A-7-76

However, the above conventional technique has the following problems.
(1) (Patent Document 1) does not describe a specific configuration or method. However, judging from the drawings, the trunk line is usually formed by a water surface float attached to a suspension rope and an adjustment float attached to the trunk rope. It is presumed that the aquaculture culvert will be sunk by installing the cultivating trough near the surface layer, changing the suspension rope to a long one when necessary, and removing the adjustment float. However, the work of changing a large number of suspension ropes into a long one as described above and the work of removing the adjustment float are very troublesome, and there is a problem that the subsidence work is not in time when dealing with a typhoon or low pressure.
(2) (Patent Document 2), two floats are attached to the outer periphery of the aquaculture ginger body, the inner float fixes buoyancy, the outer float has an air hose connected to it, and an air valve with a float is provided. It is provided with a structure that adjusts buoyancy by intake and exhaust from the air valve, and passes through the metal fittings installed on the ginger position fixing anchor installed on the seabed with a plurality of wires attached to the outer frame of the ginger body bottom part. Attach a float for sinking to the tip, draw air from the outer float from the air valve, sink the ginger body, and inject air from the compressor loaded on the ship into the outer float via the air valve and air hose. Although a floating farming ginger for use in the open ocean, characterized by floating the main body, is shown, it has the following problems.
1. The floating farm is a complex structure for use in the sea, and the air hose and feeding pipe are connected from the underwater ginger body to the air valve with a float on the water surface and the feeding port held by the float. Even when the ginger body rises or sinks, the load and impact due to waves and tidal currents are repeatedly applied between the members and the members, which may damage the wires and the joints of the members. There is a problem in durability.
2. Because a compressor is required for the ascent operation, it is constrained in use, and it is assumed that the operation will not be in time when a typhoon such as a typhoon is required. Therefore, there is a high probability that the malfunction of the apparatus will occur, and there remains a problem of lack of versatility, operability, quickness, and manageability.

  In order to solve the above-mentioned problems, the present invention provides a growing part and a supporting part in which a floating float is disposed, a fixing part having a direction changing tool, a retracting float, and connecting the supporting part and the retracting float. The growing part and supporting part, which are composed of mooring lines and hold the target organism, are usually drawn downward by a pulling float and installed at a predetermined depth below the surface of the water to adjust the length of the mooring lines. It can be moved to the required depth level by operation, and depending on the situation, it is moored so that it can be lifted by lifting the pull-in action of the pull-in float and separated and moved to another place, functionality and operability , Safety, manageability, workability, robustness, maintainability, resource saving, versatility, low cost, healthy growth of target organisms, growth promotion, productivity, fishery utilization, operational efficiency An object of the present invention to provide for the aquaculture water depth variable mooring facilities.

Moreover, since there are very few members installed near the water surface, the facility is affected by waves and tides. In addition, since the cylindrical pull-in float 8 is installed in a vertical cone shape, the vertical movement due to the waves is suppressed, and the growth parts 2A and 2B and the support part 3 are always installed in the middle layer. It is less susceptible to the effects of wave and tidal currents, fluctuations in water temperature, red tides, and rainwater desalination, reducing the stress caused by shaking and shaking of the target organisms, and avoiding the loss or damage of facilities due to aging Can Can, because deposit is less prevents insufficient oxygen deficiency and nutrients, to reduce the influence of wave and tidal current deposits itself and deposits undergo important effect that can be obtained.
The mooring line 5 standing up from the direction changer 7 is tensioned in the water due to the action of the pull-in float 8 and is not entangled with screws. Accidents can be prevented.
In addition, the conventional hanging longline type is easily affected by waves and tides on the surface and upper layers due to the structure of the facility, and the purpose is to reduce the angle between the leopard and the bottom of the water to secure the anchorage of the leash In order to prevent the shock caused by waves from being easily transmitted from the leash to the breeding department, it is necessary to secure the length of the leash more than a certain level, and when the trunk line is raised during operation, the leash is stretched and difficult to pull up. In order to alleviate this, the horizontal distance from the end of the trunk rope to the anchor rope fixing part is about 2.5 to 3 times the water depth at high tide.
The aquaculture water depth variable mooring facility 1 is structured so that the influence of waves and tides on the surface layer and upper layer is small due to the structure of the facility, and the impact caused by the waves is not easily transmitted to the breeding parts 2A, 2B and the support part 3. As will be described later, the mooring line 5 can be extended when the growing parts 2A and 2B are levitated to loosen the support part 3 and the mooring line 5, so that the horizontal distance from the end of the support part 3 to the fixed part 6 is Normally, each can be moored at 1.0 to 1.5 times the water depth at high tide, and can be moored at about 0.2 times the water depth if necessary, and the area occupied by the facility is greatly reduced, Can be used effectively.
The mooring line 5 receives a load when the pull-in float 8 moves up and down due to waves, so that it is mainly made of polypropylene split yarn or polyethylene monofilament rope having a diameter of 18 to 40 mm and a tensile strength of about 4 to 16 tons. However, a large impact is not applied except for the mooring line 5, but by using a material according to the mooring line 5, the entire facility can be used for a long time.
The levitation float 4 and the pull-in float 8 have a pressure resistance of 50 m or more, the levitation float 4 is distributed so that each part of the trunk 3 is installed at substantially the same depth, and the pull-in float 8 is one mooring cable. The number is not limited to one for five, but a plurality can be arranged in the depth direction and the horizontal direction.
When the fixing portion 6 is made of earth, it is desirable that the underwater mass is four times or more the buoyancy of the draw-in float 8, and even in a small-scale facility, the total underwater mass is 1000 kg or more. Each rope is tied to the rope ring that secures. Note that the fixing portion 6 may be formed of a concrete block, a driven anchor, or the like instead of the earthwork.
Here, the breeding part 2A mainly for seafood breeding and the breeding part 2B mainly for seaweed breeding are added to improve the production efficiency by the combined breeding of seafood and seaweed, and environmental conservation such as water quality improvement. It is intended, and can be adopted at any time in the following embodiments as well.

FIG. 2 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility of the first embodiment is moved to the upper layer.
In FIG. 2, 5 'is a mooring line for installing the growing parts 2A and 2B in the upper layer, and 5C is a mooring line upper layer adjusting part for the mooring line 5'.
In FIG. 2, the mooring line 5 'is connected to the right and left mooring line measuring part 5A by connecting the mooring line upper layer adjusting part 5C longer than the mooring line middle layer adjusting part 5B. 2B is moved to the upper layer.
FIG. 2 shows a state in which the breeding units 2A and 2B are moved from the middle layer to the upper layer in the normal water depth hierarchy shown in FIG. In this way, by simply changing the length of the mooring line, it is possible to easily move the breeding units 2A and 2B to the depth level close to the appropriate water temperature zone of the target organism for growth, thereby promoting growth.
The breeding units 2A and 2B are installed in the upper layer, but the facility is configured to be drawn in the water bottom direction with the draw-in float 8 via the water bottom direction changer 7, and is shaken because it is installed with reference to the water bottom. And the impact is suppressed, the target organism is not subject to great stress, and the facility can be preserved in normal operations other than large storms.

FIG. 3 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the first embodiment is moved to the bottom layer.
In FIG. 3, reference numeral 5 ″ denotes a mooring line in which the mooring line measuring part 5A is arranged independently to move the growing parts 2A and 2B to the bottom layer.
In FIG. 3, the mooring line 5 ″ (the mooring line measuring part 5A) is directly connected to the retracting float 8, so that the support part 3 is drawn and the growing parts 2A and 2B are moved to the bottom layer.
In the case of the conventional hanging longline type, since it is installed based on the water surface float, in order to receive strong waves and tidal currents, the deeper the water depth, the greater the blowing of the growing part becomes, making it difficult to install at the required water depth. However, in all of the variable depth mooring facilities of the present invention, one end side of the mooring line 5 is connected to both ends of the support part 3, and the other end side of the mooring line 5 is attached to the fixed part 6 of the water bottom. 7 is connected to the draw-in float 8, and the support portion 3 is configured to be drawn in the direction of the bottom of the water, and is installed with reference to the bottom of the water, so that it can be installed at the required depth level and submerged deeply.

Since the buoyancy of the float 4 for levitation causes the growing parts 2A and 2B to float after the support part 3 and the support part 3 and the mooring line 5 ″ (the mooring line measuring part 5A) are loosened, the support part 3 is reworked. Thus, the breeding units 2A and 2B can be drawn close to each other, can be easily pulled up on the ship, and necessary operations such as harvesting of target organisms and maintenance of each unit can be quickly performed.
In accordance with the above procedure, the support portion 3 can be easily lifted by connecting and extending the feeding line 5D to the mooring line middle layer adjusting part 5B in FIG. 1 and the mooring line upper layer adjusting part 5C in FIG. The required work thereafter can be performed in the same manner as described above.
Further, although not shown in the figure, the mooring line 5 "(the mooring line measuring part 5A) connected to both ends of the support part 3 is separated by detaching the mooring line 5" (the mooring line measuring part 5A) with respect to aging, red tide, rainwater desalination, water temperature fluctuation, and the like. It can be moved to a safe place, such as by coasting the required part composed of the parts 2A, 2B, the support part 3, and the floating float 4, and after being temporarily moored at the evacuation destination, it is returned to the original place. 1 to FIG. 3 can be restored.
In addition, the operation of floating the growing portion and the support portion and loosening the support portion and the mooring line can be performed in substantially the same manner in any of the embodiments of the present invention.

  From the state of FIG. 3, after attaching the sonic actuation type stopper to one drawing float 8 and fixing the mark float 9A, the drawing float 8 and mark float 9A are submerged and the other mark float 9A is removed. You can also. Thereby, the target on the water surface can be eliminated, and even if the facility is detected by a fish finder or the like, there is no clue on the water surface, and the antitheft effect can be enhanced. When necessary, the sound wave actuated stopper is released by sound wave operation, the fixed mark float 9A is floated, and the support part 3 can be floated by an operation according to the above.

FIG. 5 is a main part enlarged schematic front view showing a connected state of each part in FIG. 1.
In FIG. 5, 5 a is a connecting eye formed at the end of the mooring cable fixed part 5 </ b> A, 5 b is a connecting eye formed at both ends of the mooring line middle layer adjusting part 5 </ b> B, and 8 a is a pull-in float 8. The connecting eye 10 is a lashing cord for linking and linking adjacent connecting portions.
In FIG. 5, the connecting eye 5 a of the mooring cable fixed part 5 </ b> A and the lower connecting eye 5 b of the mooring cable middle layer adjusting part 5 </ b> B are connected by the securing cable 10, and the upper side of the mooring cable middle layer adjusting part 5 </ b> B is connected. The connecting eye 5 b and the connecting eye 8 a of the pull-in float 8 are connected by a lashing rope 10.

(Embodiment 2)
The aquaculture water depth variable mooring facility according to the second embodiment of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the thing similar to Embodiment 1, and description is abbreviate | omitted.
FIG. 6 is a partially omitted schematic front view of the aquaculture water depth variable mooring facility according to the second embodiment.
In FIG. 6, reference numeral 11 denotes aquaculture water depth variable mooring facility according to the second embodiment, 12 is a grounding part that is mainly used for landing, and a rearing part using a culture basket formed in a circular shape or a rectangular shape in plan view, and 12A A suspension hand for attaching the upper part of the growing part 12 to a support part 13 to be described later, 13 is a support part using a trunk rope, 14A is a floating float for bottoming adjustment attached to both ends of the support part 13, Reference numeral 14B denotes a floating float disposed on the support portion 13, and reference numeral 15 denotes a mooring line used for landing the growing portion 12 on a water bottom that is always installed.

FIG. 6 shows a state in which the support portion 13 is drawn into the bottom layer by the action of the pull-in float 8 to which the mooring line 15 is connected, the growing portion 12 is landed, and the suspension hand 12A is slack.
The aquaculture depth variable mooring facility 11 according to the second embodiment is different from the aquaculture depth variable mooring facility 1 according to the first embodiment with respect to the underwater weight of the contents to be accommodated such as the breeding unit 12 and the rearing target organism. The buoyancy of the float for float 14B is set to a small value, and the float is floated when the pull-in action is solved by compensating the buoyancy with the float float 14A for bottoming adjustment. This is to suppress the floating action of the floating float 14A for adjusting the bottom when it is drawn into the water bottom, so that the growing part 12 is bottomed in a stable state.
Near the bottom of the water, the effects of aging and tidal currents are small, so the facility can be prevented from being lost or damaged. With the breeding unit 12 in the bottom, scallops, abalone, scallops, sea urchins, sea cucumbers, etc. The environment is suitable for the target organism suitable for growth, and since the breeding unit 12 does not shake, it can be cultivated with sand or soil inside, and larvae, red shellfish, sea cucumber, etc. are grown under more suitable conditions Can be promoted.
In addition, since it is easy to receive a food damage near the bottom of the water, and the burying of the growing part 12 is likely to occur due to the sludge sludge, the bottom of the condition is such that the mesh of the cultured cage used as the growing part 12 is reduced to prevent the food damage or the burial is not buried. It is desirable to select
Here, in the aquaculture water depth variable mooring apparatus 11 of the second embodiment, since the impact applied to the mooring line 15 is difficult to be transmitted in order to install the growing part 12 with the bottom always attached, it is difficult to transmit the support part 13 of the mooring line 15. The distance between the end and the direction changer 7 attached to the fixed part 6 can be shortened, and the horizontal distance from the end of the support part 13 to the fixed part 6 is about 0.4 times the water depth at high tide. Moored.
As a result, the occupied area of the facility can be suppressed in a fishing ground with a deep water depth or a fishing ground where the facility is congested.

FIG. 7 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the second embodiment is levitated near the water surface.
In FIG. 7, reference numerals 15 </ b> D denote feeding cables connected between the mooring cable 15 and the pull-in float 8.
In FIG. 7, the mooring line 15 on one side is removed from the float 8 for pull-in, and the feed line 15D is connected and unwound. 12 floats together with the support portion 13.
At this time, the growing part 12 is under the water surface, but the support part 13 is loose, so that it is easy to handle, the suspension hand 12A can be pulled up to the water surface, can be pulled up on the ship, feeding, cleaning, harvesting Etc. can be easily performed. In addition, although not shown, a method of coasting a required portion composed of the growing portion 12, the support portion 13, and the floats 14 </ b> A and 14 </ b> B by cutting off the mooring lines 15 connected to both ends of the support portion 13. 6 can be moved to a safe place, and after being temporarily moored at the evacuated place, it can be easily returned to the original place and restored to the state of FIG.

Since the aquaculture water depth variable mooring facility according to the second embodiment is configured as described above, the following actions are obtained.
(1) The breeding unit 12 can be settled in a stable state, the influence of aging and tides is small, red tide, rainfall desalination, water temperature fluctuations are difficult, and the target organism is not subject to stress due to shaking, By accommodating sand, soil, or the like inside the breeding unit 12, the growth of the target organism can be promoted, the facility can be prevented from being washed away or damaged, and the healthy breeding property, growth promoting property, and maintainability are excellent.
(2) The distance from the end of the support portion 13 to the fixed portion 6 can be shortened and moored at a depth of less than half the depth of the water. It can be moored with a small size and excels in fishing ground availability.

(Embodiment 3)
An aquaculture water depth variable mooring facility according to Embodiment 3 of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the thing similar to Embodiment 1, and description is abbreviate | omitted.
FIG. 8 is a partially omitted schematic front view of the aquaculture water depth variable mooring facility according to the third embodiment.
In FIG. 8, 21 is an aquaculture water depth variable mooring facility according to the third embodiment, 22 is an example of a breeding section, and a breeding section using a cylindrical or rectangular tubular farm basket that is formed long in the left-right direction in the figure. 22A is a suspension for attaching the lower part of the growing part 22 to the support part 23 using the trunk rope, and 23A is formed of a rope body similar to the support part 23, and is arranged in parallel with the support part 23. The second support part 23a is connected to the upper part of the support part 23a. The connection part 23a is formed on both ends of the support part 23 and connected to the ends of the mooring line 25 and the rope 27 described later. Floating float attached to the part 23A, 25 is a mooring line for installing the growing part 22 on the bottom layer, 26 is a rope anchoring part formed of soil on the bottom of the water, 27 is one end side of the support part 23 and the rope This is a leash that connects the fixing portion 26.

The aquaculture depth variable mooring facility 21 according to the third embodiment is different from the aquaculture depth variable mooring facilities 1 and 11 according to the first and second embodiments in that one end side of the support portion 23 is connected to the leopard fixing portion 26 by the leash rope 27. And the support part 23 and the second support part 23A are arranged in parallel in the depth direction, and the breeding part 22 using the cultured basket is installed between them.
In FIG. 8, one end side of the support portion 23 is moored by the leash rope fixing portion 26 and the leash rope 27, and the other end side is provided with the retraction float 8 and the fixing portion 6 including the direction changer 7 and the growing portion 22 in the bottom layer. It is moored by a mooring line 25 for the purpose, and the support part 23 is drawn into the vicinity of the water bottom, and is installed in the bottom layer, which is a level where the growing part 22 is always installed.
As a result, water temperature fluctuations such as high water temperature in summer, red tides, rainwater desalination are less affected, and the target organisms can be protected. A suitable environment can be obtained in the training of facilities and sufficient facility maintenance can be achieved against aging.
In the case of a target organism that needs to be grown near the bottom of the water, if the growing portion 22 is landed on the bottom of the water, it will be damaged by shellfish, etc., or the growing portion 22 may be buried with soft mud or sludge near the bottom of the water. However, the aquaculture depth variable mooring facility 21 of the third embodiment suspends the breeding unit 22 from the bottom of the water even if the support unit 23 is grounded. It can be separated from the water bottom by the length of 22A, and can be prevented from being buried due to food damage or soft mud that is easily received when the bottom reaches the bottom, and a good growing environment can be maintained.

The aquaculture variable depth mooring facility 21 of the third embodiment performs the operation of changing the water depth of the breeding unit 22 at one place on the mooring line 25 side, so that it is shorter than the aquaculture variable depth mooring facility 1 of the first embodiment. It is possible to operate the target organisms and the facility for breeding with respect to aging.
Further, since one side of the support part 23 is moored by the leash fixing part 26, the shaking and movement of the facility are reduced and stability is increased, and the growing part 22 is moved downward by the support part 23 via the suspension 22A. In addition to being pulled, the upper part is pulled upward by the buoyancy of the floating float 24, so that a stable state is maintained. Furthermore, as a normal facility orientation, when the tidal current is installed in the longitudinal direction of the facility, the blowing of the breeding part 22 and the support part 23 and running water resistance can be suppressed, so fish, shellfish, sea urchins, sea cucumbers, etc. It is possible to reduce the stress of the target organisms for the breeding, reduce the load on the facility due to the tidal current, and prevent the loss and damage.
In the vicinity of the water surface, the pulling float 8 and the mark float 9A to which the mooring line 25 is connected are only floating, and the mooring line 25 in tension in the water does not get tangled with the screw, and the guide float 8A is attached. Since the rope 8 is made of a sinking material, it is less likely to get entangled, and the operation and navigation of the ship are safe, and it is possible to prevent a ride-off accident caused by a ship passing nearby. In addition, since there are few targets on the surface of the water and it is difficult to detect the existence of facilities, theft by outsiders can be prevented. Furthermore, the float 8 for drawing-in can be submerged by substantially the same operation as that for the aquaculture water depth variable mooring facility 1 of the first embodiment, and operations necessary for these can be performed at one place on the side of the mooring line 25.
In the case of the conventional hanging longline type, the horizontal distance from the end of the trunk rope as a support part to the rope anchoring part is moored at about 2.5 to 3 times the water depth, respectively. In the aquaculture water depth variable mooring facility 21 of the third embodiment to be used, the horizontal distance from the end of the support portion 23 to the fixing portion 6 or the leopard fixing portion 26 is 1.0 to 1 of the water depth at high tide. It can be moored at about 5 times, and the area occupied by the facility can be significantly reduced.
Note that the rope 17, the support portion 23, and the mooring line 25 are substantially the same as the mooring line 5 used in the aquaculture water depth variable mooring 1 of the first embodiment.
The aquaculture basket used as the breeding unit 22 has a low shielding rate and excellent water exchange, residual feed and excrement outflow characteristics, similar to the breeding unit 12 of the aquaculture water depth variable mooring facility 11 of the second embodiment. A metal frame or a combination of a special rope frame and a net is preferably used.

FIG. 9 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the third embodiment is moved to the upper layer.
In FIG. 9, 25 ′ is a mooring line used when moving the growing part 22 to the upper layer, 25 A is also used as the mooring line 25, and a mooring line fixed part of the mooring line 25 ′, and 25 C is a mooring line It is a mooring line upper layer adjustment part of the mooring line 25 ′ that connects the standard part 25 </ b> A and the pull-in float 8.
In FIG. 9, one end side of the support portion 23 is moored by a mooring line 25 ′ that connects a mooring line measuring portion 25 </ b> A and a mooring line upper layer adjustment unit 25 </ b> C, and the growing portion 22 is installed in the upper layer.
This is the case when shellfish, sea urchins, sea cucumbers, etc. that are suitable for breeding near the bottom of the water, when they are grown near the upper layer close to the appropriate water temperature, such as during the water temperature rising period from spring to early summer or the water temperature falling period in early winter. While promoting the growth in a water temperature zone as close as possible to the optimum water temperature, the growth part 22 is installed in the upper layer, but the structure of the facility can stably suppress shaking and blowing. Since it is submerged in a hierarchy at a predetermined depth from the water surface, it is possible to avoid the effects of summer high water temperature, desalination due to aging and rainfall, red tide, etc. as expected.

FIG. 10 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the third embodiment is levitated near the water surface.
In FIG. 10, reference numeral 25 </ b> D denotes a feeding line connected between the mooring line 25 and the pull-in float 8 when the mooring line 25 is drawn out.
In FIG. 10, the mooring line 25 is removed from the drawing float 8 and the drawing line 25D is connected to the drawing line 25D so that the drawing action of the drawing float 8 is released. Since the second support portion 23A, the support portion 23, and the rope 17 are slackened, the second support surfaced on the water surface without any load being applied. The breeding unit 22 can be pulled to the work ship by pulling the part 23A, and operations such as cleaning, feeding, sorting, and harvesting can be easily performed.
In the case of the conventional hanging longline type, in addition to the weight of the breeding unit and the target organism, the tension of the leopard rope is applied, and in order to lift the breeding unit to the surface of the water or on the ship, equipment with a large lifting capacity is required. As the trunk rope was pulled up, the rope was tightly stretched, and the trunk rope was stretched, which was dangerous to the work related to the breeding department, but the variable mooring facilities for aquaculture of each embodiment of the present invention are all Even if the lifting work is not performed, the necessary parts such as the breeding part surface and the support part, the mooring line, and the leash are loosened, so that the necessary work after the surface can be safely and easily performed.

FIG. 11 is a partially omitted schematic front view showing a state when evacuating a breeding portion of the aquaculture water depth variable mooring facility according to the second embodiment.
In FIG. 11, 28 is a tether for connecting the rope 27 and the mooring line 25 to remain in the water, 28 </ b> A is a tether float attached to the tether 28, and 28 a is a mooring line formed at both ends of the tether 28. 25, a connecting part such as a connecting eye to which the ends of the rope 27 are connected, 29 is a work ship mooring part, 29A is a work ship mooring line, and 29B is a work ship mooring fixing part.
FIG. 11 shows a procedure for evacuation for storm, red tide, rainwater desalination, etc., and the support part 23 is separated from the mooring line 25 and the rope 27 from the state of FIG. While the part 22, the support part 23, and the second support part 23A are connected, they are floated by the buoyancy of the floating float 24 and can be moved as they are, and the mooring line 25 and the rope 27 are connected by the connecting line 28a. The tether float 28A is attached and left in water.
At this time, since the connecting portions 23a and 28a such as connecting eyes are formed at both ends of the support portion 23 and the connecting cord 28, the mooring cord 25 and the rope 27 can be easily attached and detached.
In FIG. 11, necessary parts such as the breeding unit 22 that needs to be evacuated are separated and floated. In this state, the breeding unit 22 in which the target organism is accommodated is laid together with the support unit 23 and the second support unit 23A. Thus, it is possible to move to a safe place, and after temporarily mooring at the evacuation destination, it can be easily returned to the original place and restored to the state shown in FIGS. It is possible to simply coast using the connecting portion 23a of the support portion 23, and the workability is excellent.
Here, the method of ascending and evacuating the breeding unit 22 and the like is substantially the same in the aquaculture depth variable mooring facilities 1 and 11 of the first and second embodiments and the aquaculture depth variable aquaculture facilities of the following embodiments. The same procedure can be performed.
In the case of a conventional hanging longline facility, it is difficult to evacuate the required part such as the breeding part to another place or move from the position where the growing part is installed to a deeper place. It took a lot of time and there was the actual situation of being injured without being in time for a sudden situation.
Here, the work ship mooring part 29 installed on the surface of the water by the work ship mooring line 29A and the work ship mooring fixing part 29B is installed for the purpose of mooring the mooring line 25 and mooring the work ship when performing necessary work at sea.
