、これにより本各発明をするに至ったものである．By merging deep seawater and surface seawater, pushing up various nutrients such as nitrates and phosphates in the seabed or deep seawater, and promoting the generation of phytoplankton in the surface layer where sunlight reaches, it is possible to improve the production of fish and other fish. It is possible to dramatically increase resources and create highly productive artificial fishing grounds. This can be easily inferred from the fact that areas where warm and cold currents meet are natural fishing grounds. By the way, in order to merge deep seawater and surface seawater, it seems that proposals include building large structures on the ocean floor, sending compressed air toward the ocean floor, and even using pumps. In the ocean, where weather and sea conditions change rapidly and water pressure is high, all of these methods are not only extremely difficult to construct or install, but are also extremely expensive, making them economically unfeasible. It seems that there are few. As a result of intensive research, the present inventor was able to obtain the knowledge that it is possible to transform deep seawater into upwelling currents and surface seawater into descending currents by extremely simple and economical means. This is what led to the present inventions.

場合と同様に実施するものである．First, an embodiment of the current variable curtain of the present invention will be explained in detail. The current variable curtain A of the present invention has a unit sheet a having a diagonal line 1.
It is made by installing multiple pieces in series. The unit sheet a is made of high-strength synthetic fiber such as polyester synthetic fiber, and the groove 1 is formed as follows. For example, by aligning the left and right widths 2, 2, which are about one-fourth of the total length of the upper edge of the above-mentioned Hewei fiber fabric a' of a rectangular shape of 50 m long and 20 m wide, in the center, a cylindrical shape is formed at the rear side of the upper center. After forming the section 3 (FIGS. 2 and 3) and once separating the cylindrical section 3 at the joining section 4,
The gathered portion 4 is sewn 5 by using a patch cloth as appropriate.
At the same time, the separated portion of the cylindrical portion 3 is also sutured 6, and a required length 3' of the distal end of the cylindrical portion 3 is cut off, thereby forming the cylindrical portion 3 into a muscle outlet 7. On the other hand, on the lower side of the same fabric a', there are several strips on each side with a width of 8.8, which is about one-fourth of the total length of the lower edge. I
Take 9 and sew. As a result, the length of the Hewei fiber fabric a' remains 50m.
One width is 10m, which is about half of the original width, and the unit sheet a has the above-mentioned zero line l. This unit sheet a is made by sewing a required plurality of sheets, for example 10 sheets, in a row by overlapping and sewing the required width of the vertical edges of adjacent sheets with a non-stretchable rope-like core material 10 interposed between them. At the same time, the required width of the entire periphery of this continuous arrangement is covered with the same non-stretchable rope-like core material 11, folded back and sewn, and the eyelet fittings 12 are attached at the required intervals inside the rope-like core material 11. Attach and install with. As a result, the variable current curtain A in FIG. 1 is implemented. This current transformation curtain A further connects the required plurality of sheets to the eyelet metal fittings 12 between the adjacent vertical edges of the rope 1.
3 and connect them to create a current transformation curtain A' of the desired length.
(Figure 7). Reference numeral 14 denotes aX with a float 15 placed along the upper edge of the variable current curtain A', which is attached by an auxiliary rope 16 inserted through the eyelet fitting 12. The float 15 is made of a material and structure that can sufficiently withstand the water pressure at the installation depth, and fi'I! 414, or a type that ties around the main rope 14, as appropriate. Reference numeral 17 denotes a lower rope with a weight l8 placed along the lower edge of the variable current curtain A', and is also attached by an auxiliary rope 19 inserted through the eyelet fitting 12. As for 18, sandbags, concrete blocks, etc. are attached to the lower rope 17 using appropriate means such as hanging ropes. The horizontal variable current curtain A' has a total length of 500 to 2000
For example, in the arrangement shown in the plan view of FIG. 11, a plurality of fish of m size are prepared and installed vertically on the seabed of the sea area at a depth of 200 m, thereby creating an artificial fishing ground of the present invention. In the above, each current variable curtain A' is constructed by anchoring the weight 18 to the bottom of the seabed, floating the float 15 in the water, and anchoring the anchor row 120 in a V-shape in plan. ! 114 to V! It stands upright in a stretched state (Figure 8). The installation of this variable current curtain A' is carried out as follows. The current variable curtain A' is wound so that the lower edge side is on the inside and the upper edge side is on the outside, and one anchor rope 20 tied to the ILX 14 is tied to one end of the wound curtain on the work boat. The current variable curtain A' is made into a V-shape in plan and stretched between the ocean floor and the ocean floor, and a work boat is run to unwind the current variable curtain A' from one side and hang it down into the water in the direction of its extension. The other anchor rope 20, which is tied to the base X14 at the other end, is also made into a V-shape in plane and stretched between it and the sea bottom. Ri1
8 to the bottom of the sea, float 15 in the water, and [! 114 is placed in a standing position under tension. Deep seawater, which is flowing quietly along the ocean floor, first spreads to the left and right when it hits the variable current curtain A', and then gradually increases in height. As a result, the current-changing curtain A' is entirely deflected in the flow direction at λ, which contains the deep-sea water current, and at this time, the deep-sea water current rises along the current changing curtain A', and each unit series is Toa also gradually enlarges the bulge in the flow direction due to the resistance of the seawater flow to form the deep seawater 1, that is, to wet the deep seawater from the seawater outlet 7 to each unit seam. It is ejected upward in the direction of seawater flow, which is the opposite side of a. As a result, deep seawater transforms into upwelling currents and merges with surface seawater. In the above, the variable current curtain A' and the unit sheet a are:
Rope-shaped core material 10 whose periphery is non-stretchable. Since it is regulated by l1, the inside part is well bent or swelled so that the current transformation effect is carried out smoothly. Furthermore, even if the deep seawater current hits the current-changing curtain A' from either the front or the back, the deflection of the current-changing curtain A' and the bulge of each unit seat a occur along the flow direction of the current. , and the groove outlet 7 opens in the same direction (Figures 9 and 10). In the above, the deep drought is changed to Table II.
We have explained the case of merging with seawater, but on the other hand, to transform surface seawater to merge with deep seawater and thereby return the combined seawater to a place where sunlight can reach, do the following. In the one shown in FIG. 7, the current changing curtain A', which is made by connecting a plurality of current changing curtains A of the above structure and having a desired length, has the upper edge where the horizontal outlet 7 is located, and The parent w414 with the float 15 was placed along it, and the side with the 119 was used as the lower edge, and the lower w417 with the weight l8 was placed along it, but for the current variable curtain A'', on the contrary,
! The side where I9 is located is the upper edge, and the parent *l4 with float l5 is placed along it, and the side where the zero strip outlet 7 is located is the lower edge, and below it! 11117 along, and a sandbag as above on this lower rope l7. A weight l8 such as a concrete block is connected with a connecting rope 21 of the required length. This variable current curtain 6" is installed at a required depth where the surface seawater flows, with the weight 18 touching the bottom of the seabed, the float 15 floating in the water, and the main rope 14 being tensioned by the anchor rope 20. The bridge is erected (Fig. 12)
．． When this current-changing curtain A1 is hit by a surface seawater current, it becomes pregnant and the whole bends greatly in the direction of the flow, and
At this time, each unit sheet a also gradually expands in the flow direction due to the resistance of the seawater flow to form the groove 1, and the surface seawater is pumped from the groove outlet 7 to each unit sheet. The water is ejected on the opposite side of A, that is, downward in the direction of seawater flow. As a result, the surface seawater turns into a downward current and joins the deep seawater, and at this time, no matter whether the flow of surface seawater hits the current transformation curtain A'' from either the front or back side, it will flow into the current transformation curtain A#. Deflection and bulge of each unit sheet a occur along the flow direction of the seawater current, and the striped outlet 7 opens in the same direction (Fig. 13). Installation of this current transformation curtain A'' This is carried out in the same manner as in the case of the current variable curtain A'.

こともできる．According to the artificial fishing ground of the present invention, the deep seawater current or the surface seawater current hits the current-transforming curtain, inflates its entire body and each unit sheet, and flows along the diagonal lines, resulting in a deformed mass. The water then merges with surface seawater or deep seawater, respectively. In the above, the current-changing curtain is made up of a series of unit sheets, and regardless of whether the flow direction of the seawater current is forward or backward, it swells in the direction of flow due to the resistance of the seawater current, and performs a predetermined current-changing effect. In addition, the grooves of each unit sheet have groove outlet ports, which allow the seawater flow to blow through to the opposite side of each unit sheet, that is, in the flow direction of the seawater flow, so that the resistance of the seawater flow can be reduced, and the resistance can be even greater. The entire current-changing curtain bends, flexibly resisting the seawater current. According to the method of the present invention, a variable current curtain that has been wound so that the lower edge side is inside and the upper edge side is outside is placed at one end! Stretch one of the anchor ropes tied to llw4 between it and the bottom of the sea area, and unwrap the current flow curtain from one side and let it hang in the water and let it out in the direction of its extension. At the same time, the other anchor rope tied to the main rope at the other end is also stretched between the sea floor and the bottom of the sea area, so that the weight of the variable current curtain is brought to the bottom, the float is suspended in the water, and the main rope is suspended. By setting the net upright under tension, it is possible to easily create the desired artificial fishing ground, and it eliminates the various obstacles that would arise when constructing a large rigid structure on the seabed in deep water, which has been proposed in the past. No. Furthermore, the current variable curtain of the present invention has a plurality of unit sheets each having a circular strip having a circular strip outlet, or a plurality of unit sheets each having a circular strip having a circular strip outlet, or a plurality of unit sheets having a circular strip having a circular strip outlet, or a plurality of unit sheets having a circular strip having a circular strip outlet, or a plurality of unit sheets are arranged in series with the overlapped portions of adjacent unit sheets. It is manufactured using an extremely simple structure, either by interposing a non-stretchable rope-like core material between the two, or by attaching a main rope with a float along the upper edge and a lower rope with a weight along the lower edge. Not only is it easy to do this, but it can also be done at a low cost. Moreover, even if the current variable curtain is once installed in an upright position, it can be easily changed or removed if necessary, and it can also be easily pulled up for inspection.
