Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for creating a seaweed bed (also referred to as a marine forest) centering on seaweeds and improving a marine environment to bring about propagation of fish and shellfish. The present invention relates to a structure for creating a seaweed bed capable of forming a permanent seaweed bed. Specifically, a structure such as a concrete block (hereinafter, referred to as a "skeleton structure") that includes a columnar portion disposed substantially vertically in the sea and can also function as an epiphytic floor for seaweed, A seaweed seed carrier for attaching a seaweed for transplantation to the skeletal structure is provided. In particular, the seaweed seed carrier can be securely mounted at a predetermined position of the columnar portion.

[0002]

2. Description of the Related Art At present, the promotion of coastal fisheries is an important issue in Japan, and the propagation and cultivation of seafood and seaweed are being attempted. However, in the coastal area, the so-called "iso-yake" phenomenon, in which the seaweed beds disappear due to various causes and the seafood that uses the seaweed beds as a place of life, is drastically expanding.

[0003] In general, seaweed grows on a relatively shallow seabed rock surface. However, the growth environment is extremely poor in the coastal waters because there is no spore supply source because there is no mother algae nearby, and rocks are covered with lime algae and seaweeds are difficult to grow. Also, the growth of seaweed is originally difficult in sandy and muddy waters. Therefore, in the regeneration of seaweed beds in such seashores and in the construction of seaweed beds in sandy and muddy seas,
It is important to transplant seaweed.

Conventionally, as a method of creating a seaweed bed, there has been known a method of installing a structure devised variously in the sea and waiting for the seaweed to naturally grow on the structure. . However, since these conventional methods rely on natural epiphytes, the epiphytic state of seaweeds, particularly in the early stage of development, is not only greatly influenced by uncertain natural factors, but also the development efficiency and time required for development are high. There was a fundamental problem in terms of certainty.

[0005] In recent years, young seaweeds for forming are formed on thin twisted yarns called seedlings used in seaweed aquaculture in advance, and the seedlings are directly wound around an appropriate position on a structure for construction such as a concrete block. Attempts have been made to submerge the seaweed on the surface of a construction structure by using the seaweed seeds as nuclei.
However, this conventional method is not only difficult to attach the seed and seedlings to the construction structure, but also its attachment state is unstable, and it is almost difficult to apply it to the construction structure installed in the sea. there were. In addition, if there is any problem in the installation state of seed seedlings after submersion, the seedlings that are thin and thread-shaped and are unstable in shape are likely to deteriorate from the problem location and easily fall off. There were drawbacks. In particular, seaweed seedlings have to be handled in a very small juvenile state because the seedlings themselves have little strength, and often do not grow smoothly after transplantation, resulting in a low success rate of creation. For this reason, there are many problems in the method of directly applying seed seedlings as described above as a means for transplanting seaweed seeds and seedlings, and the fact is that practical use has not been advanced.

Accordingly, the present applicant has prepared in advance a seaweed seed / seed carrier in which a seaweed seed / seedling at an appropriate growth stage is supported on a ring-shaped carrier base made of a suitable elastic material such as a synthetic resin.
As a seaweed for transplantation, a technique has already been proposed in which a seaweed bed is created from the seaweed seeds and seedlings that have settled on the column at the appropriate position on the columnar portion of the construction structure (skeleton structure) as a seaweed for transplantation. (Japanese Unexamined Patent Application Publication No. 10-136813,
000-139267). In the seaweed bed creation by the combination of this pillar-shaped construction structure and the seaweed seedling support,
There is an advantage that the work of attaching the seaweed seeds to the construction structure on the barge is facilitated, and the attachment state thereafter is also stabilized. In particular, since these transplanted seaweeds are fixed to the columnar portion which is installed almost vertically in the sea, the growth of seaweed seeds is greatly improved as compared with the conventional method, and good results have been obtained. . That is, by introducing the seaweed seeds to the seabed in the form of attaching an appropriate number of seaweed seed carriers to the columnar portions of the construction structure, it is possible to increase the amount of seaweed seeds introduced per unit area of the sea area. In addition, oxygen and nutrients are evenly distributed on the columnar portion, and the growth conditions for the seaweed's water depth are easily satisfied,
The success rate of land reclamation is extremely high because it is not easily affected by erosion and drifting sand.

[0007]

In the prior art described above, when seaweeds for transplanting are respectively attached to a plurality of portions of the columnar portion of the construction structure, appropriate intervals are set so that adjacent seaweeds do not compete with each other. It is important to secure them, and it is necessary to properly control the mounting position of the seaweed seedling support. In addition, seaweed seeds placed in the air decrease in freshness over time, and especially in the early stages of the growth stage, the deterioration is more rapid. In the case of mounting on a surface, it is desirable to complete the mounting operation in as short a time as possible and settle down. If it takes much time to install the seaweed seed carrier, the subsequent growth of seaweed seeds will be greatly affected, and the success rate of seaweed beds will be reduced. Therefore, at the time of construction, it is convenient if there is a mark at a mounting portion of the columnar portion so that the mounting position of the seaweed can be visually confirmed. In response to such a construction request, the seaweed bed construction structure disclosed in Japanese Patent Application Laid-Open No. 2000-139267 provides a plurality of annular grooves at appropriate intervals in advance on the outer peripheral surface of the column. By adopting a configuration in which the ring-shaped seaweed seed-bearing tool is fitted in the annular groove, the seaweed seed-bearing tool can be quickly attached to an appropriate position of the columnar portion. Moreover, since the seaweed seed carrier is securely held in the annular groove and does not shift even when receiving the ocean current, the temporary roots of the seaweed seeds on the seaweed seed carrier grow smoothly, and the Can be set on the columnar part.

In the above-mentioned conventional example, concrete or synthetic resin is generally used as a material of a pillar constituting a part of a skeletal structure. Appropriate molds are required according to the external shape of the body. When a plurality of annular grooves are formed at predetermined positions on the outer peripheral surface as described above, generally, a ridge for forming the annular groove is provided on the inner peripheral surface of the mold. However, such a processed mold material is not only expensive, but also complicates the manufacturing process compared to the case of manufacturing a column with no peripheral surface, which increases the manufacturing cost of the skeletal structure. Is one of the factors. In addition, since the position of the annular groove becomes a fixed dedicated mold material, it basically responds to the change of the mounting position of the seaweed seed carrier that is set according to the environment of the sea area targeted for seaweed bed development There is a problem that cannot be done. Also, the formation of the annular groove on the outer peripheral surface of the column body causes a cross-sectional defect and causes a decrease in the strength of the column body. Therefore, it is necessary to consider the reinforcing means thereof, which also contributes to an increase in cost. ing.

[0009] The applicant of the present invention has conducted extensive and detailed studies in view of the importance of low cost and high design freedom as a requirement for widespread use of such a structure for seaweed bed development. Thus, the present inventors have conceived a structure for creating a seaweed bed according to the present invention. That is, without providing an annular groove on the outer peripheral surface of the pillar of the skeletal structure, it is possible to quickly attach the seaweed seedling support tool to the appropriate position,
It is an object of the present invention to provide a seaweed bed creation structure that can easily respond to a change in the mounting position.

[0010]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, at least one pillar is erected on a block-shaped base, and a seaweed seedling is supported on a support base. In a seaweed bed creation structure in which the supported seaweed seed-bearing device is attached to the outer peripheral surface of a pillar, the seaweed seed-bearing device is attached to a locking body fixed at a predetermined position on the outer surface of the pillar. It is characterized by being engaged via a.

That is, according to the present invention, an appropriately shaped engaging body is fixed in advance at a predetermined position on the outer peripheral surface of the column to which the seaweed seed carrier is to be attached, and the supporting base is engaged with the engaging body. Thus, since the seaweed seed-bearing device is engaged, the locking body serves as a mark of the mounting position as it is, and the seaweed seed-bearing device can be quickly mounted. Furthermore, since the seaweed seed and seedling holding device is attached via the locking body fixed to the surface of the column, the position thereof does not shift during the submerging operation, and the column is not moved by the current even after submerging. Does not shift in the circumferential direction or the vertical direction. For this reason, the seaweed seedlings on the seaweed seed-bearing device reliably settle at a predetermined position on the pillar surface in a short period of time. Such a pillar can be made of a general-purpose mold material without using an expensive dedicated mold material, so that it is inexpensive, and has no problem in strength because there is no cross-sectional defect. Furthermore, since the fixing position of the locking member can be selected at any position on the outer peripheral surface of the pillar, it is easy to cope with the case where the mounting position of the seaweed seedling support is changed according to design conditions.

In the above construction, the support base and the locking member of the seaweed seed and seedling support tool are each formed in a substantially annular shape, and each of the support bases is provided with a hookable portion which can be hooked to each other. The locking body and the support base form a pair of annular bodies, and each of the locking bodies and the supporting base are provided with engaging portions that can be engaged with each other. Thus, the support base may be engaged with the locking body in an annular state. In any case, each locking body serves as a mark when attaching the seaweed seed and seedling holding tool, and the seaweed seed and seedling holding tool is securely fixed to a predetermined position of the pillar by the locking body.

Further, according to the invention of claim 4 of the present application, a seaweed seed / seedling support tool in which a seaweed seed / seedling is carried on a supporting substrate in a skeletal structure having at least one pillar standing on a block-shaped base. Is attached to the outer peripheral surface of the column, the seaweed seed and seedling holding tool is attached to the non-applied portion of the column where the algal nutrient paint is applied to the outer peripheral surface while leaving a predetermined position in advance. It is characterized by being able to. In this case, since the non-applied portion existing at a predetermined position on the outer peripheral surface of the column functions as a mark of the mounting position, the seaweed seedling support tool can be quickly and securely mounted at the predetermined position on the column as in each of the above inventions. Can be. Furthermore, the seaweed seedlings attached to the pillar surface absorb nutrients contained therein and grow well due to the presence of the coating layer of the algal nourishing paint, and the seaweed grows throughout the skeletal structure. Become thriving.

The algal nourishing paint in the above invention may be a paint containing a general chemical fertilizer. Among them, a photosynthetic bacterium proposed by the present applicant, a carrier using porous particles, and a nutrient component of the photosynthetic bacterium are proposed. A water environment improving paint (see JP-A-5-247378) is particularly suitable. When this paint is applied to the surface of the pillar, it maintains a high epiphyte rate of seaweed and can stably supply nutrients necessary for the growth of seaweed for a long period of time.
It is convenient for growing seaweed seeds that are the core of seaweed bed development.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION In the practice of the present invention, various types of seaweed seed and seedling carriers used in the above inventions can be selected. In other words, the seaweed seed and seed carrier
Appropriate material, a supporting substrate made of a shape in which a seaweed seedling for transplantation is supported, and by handling with the supporting substrate interposed, the mounting work to the pillar is facilitated,
In addition, there are many advantages such as preventing damage to the seaweed seedlings during the installation work and facilitating storage before construction. Specifically, for example, a string-shaped body having an appropriate thickness and rigidity such as a rope or a hose is used as a support substrate for the seaweed seedlings, and the seaweed seedlings are formed by winding the seedling thread described above on the string-like body,
Some are grown in the sea until the leaf-like portion becomes appropriately large. In this case, what is grown in the state of a long cord-like body may be divided into appropriate lengths according to the dimensions of the column and used, or may be grown as long as it can be applied to the column. Further, the seaweed seed carrier comprising a string-shaped body on which these seaweed seeds have been grown may be applied as it is, but this string-shaped body is used as a first supporting base, and further a rod-shaped, a band-shaped, and a plate-shaped. It is also possible to apply the present invention to a pillar in combination with a second supporting substrate having an appropriate shape such as a shape. It corresponds to the seaweed seed / seed carrier. Then, at the mounting position of the seaweed seed and seedling holding tool on the outer peripheral surface of the pillar, a locking body having a shape suitable for the supporting base may be selected and fixed in advance. That is, in the case of the former seaweed seed / seedling support tool mainly composed of a string-shaped support base, for example, an L-shaped stopper is fixed at a plurality of locations along the circumferential direction of the mounting position at the column side as a locking body on the pillar side. Then, the supporting base portion can be fitted and engaged with them. Further, in the seaweed seed / seed carrier having the second supporting base, an appropriately-shaped engaging body capable of engaging the second supporting base is fixed in advance to a predetermined position of the column, and the second supporting base is fixed. It will be attached via a base.

As a specific example of the second support base, a flexible material such as a synthetic resin is used to form a C-shape or the like in a substantially annular shape with one portion opened, and the gap between the open ends is widened. The one that can be mounted in the lateral direction with respect to the pillar body, and the same material is formed in a substantially strip shape, and the one that is curved and attached annularly along the peripheral surface when attached to the pillar body;
Further, there are several types, such as an endless ring, which is inserted into the column from the upper end thereof.
However, in any case, if a structure is provided in which a part of the seaweed seed and carrier is fixed by the engaging means with the engaging body, the fixing of the seaweed seed and seedling holding device is more reliable. And particularly, speeding up the installation work at sea. In the case of the former end-like substrate having a substantially annular or band-like shape, the annular state can be maintained even after the material is attached to the column by the elasticity of the material itself or a hooking means provided at the end. It is preferably made of a flexible material such as a synthetic resin, rubber, or metal. Specific examples of the synthetic resin include a polyamide resin, a thermoplastic elastomer, a polyurethane, and a polyolefin resin.

In order to grow the seaweed seeds on the string-shaped supporting substrate, a method generally used in seaweed aquaculture can be applied. For example, a seedling suitable for attaching seaweed spores such as Cremona (trade name) is immersed in a water tank in which the seaweed spores float, and the seaweed spores are attached to the seedlings to germinate. Attached by being spirally wound around a suitably thick supporting substrate such as a rope or hose, and then horizontally installed or suspended in the sea, and the temporary roots of the seaweed larva attach to the supporting substrate And grow to an appropriate size that can withstand transplantation. As the kind of seaweed used here, when the main purpose is to use it as a feed, seaweed seaweeds such as alame, scallop, and black ome are preferable, and among them, the vine seaweed which is highly adaptable to the environment is particularly preferable. Of course, the present invention can be widely applied to not only seaweed seaweeds but also other seaweed species such as honda straw. The size of the seaweed when used as a seaweed seed carrier varies depending on the type of seaweed, the construction time, the environment of the creation area, and the like. Generally, the length of the leaf portion is preferably about 10 cm or more. In addition, when the string-shaped body with the seaweed seeds is used as the first support substrate and is used by being combined with the second support substrate, it may be arranged along the longitudinal direction of the second support substrate, or in some places. It may be provided, and when grown in the sea in the form of a long string, it can be cut into appropriate lengths when needed. In this case, since it is not necessary to grow in the state of the seaweed seed carrier, the space required for producing the seaweed seed carrier can be reduced. In addition,
In order to couple the first support base to the second support base, for example, a plurality of hook-shaped portions are formed at predetermined intervals on the outer peripheral surface side of the second support base, and the first support base is fitted therein. Alternatively, both may be bound by a separate fastener.

Further, the skeletal structure serving as an epiphytic floor of seaweed is one in which at least one pillar is erected on a concrete base having an appropriate shape such as a cross shape or a rectangular shape in plan view. As the material of the pillars, metal, wood, synthetic resin, etc. can be used in addition to concrete, and the cross-sectional shape is not limited to a circle but may be a polygon or a hollow inside. . In addition, when the cross-sectional shape of the columnar portion is polygonal, the supporting substrate of the seaweed seed and seedling supporting device naturally has a shape suitable for it. And it is generally assumed that the mounting work of the seaweed seed / seedling holding device to these skeletal structures is performed on a barge in a target sea area,
It may be performed in the sea after the skeletal structure has been deposited.
Even in such a case, the attachment position of the seaweed seed / seed carrier is clear, which is convenient for performing the operation.

FIG. 6 is a front view of the structure for creating a seaweed bed according to the present invention, showing a state in which the seagrass seed / seed carrier 1 is being attached to the skeletal structure 2. This skeletal structure 2 has a substantially cross-shaped base 3 made of concrete, and a circular column 4 made of a similar material, each of which is provided at four protruding portions of the cross.
The books were erected one by one. Locking members 10 (see FIGS. 1 and 2) are provided at regular intervals on the outer peripheral surface of each pillar 4.
Each is fixed to a predetermined position in advance. These locking members 10 expand both ends of the band-shaped main body 11 against elasticity,

FIG. 7 is a cross-sectional view showing a main part of the attached state of the seaweed seedling support 1. Here, the seaweed seed / seed carrier 1
Are stacked from the outside on the locking body 10 fixed to the outer peripheral surface of the column 4, and in this state, the locking hole 28 as a locking section in the second support base 20 and the locking section The hook 14 is securely fixed by engaging with the hook-shaped projection 14. In addition, if a specific mounting procedure is described also with reference to FIG. 6, the operator is located toward the connecting portions at both ends of the locking body 10. Next, the seaweed seed and seedling holding tool 1
On the back side of the column 4, the open end side of the second support base 20 is expanded, and in this state, the second support base 20 is externally fitted to the column 4 from the back side and stacked on the locking body 10. At this time, the projecting piece 15 located on the opposite side of the coupling portion of the locking body 10 can support the seaweed seedling carrier 1 before being engaged. It helps to reduce the burden on the user. Then, as described above, the locking hole 28 of the second support base 20 is

As described above, in the structure for constructing a seaweed bed according to the present invention, since the anchor 10 serving as a mark is fixed to the position where the seaweed seedling carrier 1 is to be mounted in advance, the worker may be lost. The seaweed seed / seed carrier 1 can be quickly and reliably attached to an appropriate position without any need. Therefore, when performing the installation work at sea, the seaweed seedlings 3 for transplantation are required.
The damage to 1 is small, which leads to an increase in the success rate of seaweed bed development. Incidentally, the length of the pillars 4 in the skeletal structure 2 is about 4 m, and in this case, the number of the seaweed seed and seedling holding tools 1 attached to one pillar 4 is preferably about 7 pieces, It is changed as appropriate depending on the type of seaweed seeds used. Furthermore, algae paint may be applied to the ridge on the upper surface side of the base 3 or the outer peripheral surface of the column 4.

Next, FIG. 8 shows a perspective view of a locking body used in the second embodiment of the seaweed bed construction structure according to the present invention, and FIG.
FIG. 3 is a cross-sectional view showing a main part of a state in which the seaweed seed / seed carrier is attached to the anchor. The locking body 40 used here is
Two hook-shaped projections 41 are formed on the surface of a curved plate that is adapted to the curved surface of the column 4 to be fixed, and an adhesive is applied to a predetermined position of the column 4 in the same manner as in the previous embodiment. Is fixed through. In this embodiment, the seaweed seed / seed carrier 1 of the above embodiment is used.
Is applied, and the hook holes 28 as the hooking portions of the second support base 20 are hooked into the hook-like projections 41 as the hooking portions of the locking body 40.
The seaweed seed / seed carrier 1 can be securely attached to the column 4 at a predetermined position.

In both of the above embodiments, the locking members 10 and 40 serve not only as a mark for the mounting position of the seaweed seed carrier 1 but also for fixing the seaweed seed carrier 1 to the column 4 more firmly. It also functions as a means. In the construction of such a structure for seaweed bed creation, it is an important technical matter that determines how quickly a perishable seaweed seedling is attached to a predetermined position of a pillar and settles, which determines the success rate of seaweed bed creation. Therefore, if the structure can be fixed only by the seaweed seed and seedling holding device without using the locking body, it is possible to cope with this by simply indicating the mounting position on the outer peripheral surface of the pillar.

FIG. 10 shows a third embodiment of the structure for creating a seaweed bed according to the present invention, in which no locking member is used. In other words, the outer peripheral surface of the pillar 4 erected on the base 3 is coated with a coating film 6 made of algae paint except for the position where the seaweed seed carrier 5 is to be attached. The non-applied portion 7 on which the algae paint is not applied is attached as a mark. FIG. 11 shows a method of forming the non-applied portion 7, in which a masking tape 8 is wrapped around a predetermined position of the column 4 in advance, and a spray gun 9 or the like is used around the masking tape 8 as appropriate to cover the entire outer peripheral surface. After applying P, the masking tape 8 is removed to form the non-applied portion 7. In this case as well, since the mark is present on the surface of the pillar 4 as in the above-described embodiment, the seaweed seedling support 5 can be quickly attached to an appropriate position. In the seaweed seed / seed carrier 5 used here, the support base 51 is a modification of the second support base 20 in the seaweed seed / seed carrier 1 used in the above-mentioned embodiment, although not explicitly shown in the figure. That is, a hook-shaped projection is provided in place of the hooking hole 28 at one end, and the hook-like projection is provided at the hooking hole 2 at the other end.
By engaging with 8, the ring itself can be connected in a ring shape, and the shape of other parts and the use of the first supporting substrate 30 on which the seaweed seeds 31 have been grown are the same. Therefore, due to the presence of the substantially U-shaped bulging portions provided at two places of the second support base 51 made of a material having moderate elasticity, the second supporting base 51 is elastically fitted to the column 4. Therefore, the column 4 can be reliably fixed at a predetermined position without providing a locking body.

In each of the above embodiments, the first supporting substrate 30 on which the seaweed seeds 31 have set is replaced with the second supporting substrate 2.
Although the case where the thing attached to 0,51 and integrated was applied as a seaweed seedling support tool is described, it is also possible to handle them separately. That is, the first supporting substrate 30 on which the seaweed seedlings 31 have been grown is directly used as a seaweed seedling supporting tool, and the first supporting substrate 30 is attached to the second supporting substrates 20 and 51 previously fixed to a predetermined position of the column 4, In one embodiment or the second embodiment, only the second support base 20 is previously coupled to the respective locking bodies 10 and 40 fixed at predetermined positions of the column 4, and the seaweed seeds and seedlings are immediately before the sinking. The attached first supporting substrate 30 may be attached to the second supporting substrate 20 as a seaweed seedling supporting device. Also,
The second support substrate 51 used in the third embodiment may be fixed to the column 4 and the first support substrate 30 may be attached thereto. When these work procedures are selected, the second support substrate 51 is used. 20 and 51 function as locking members, and the same effect is obtained. Furthermore, the seaweed seed and carrier may be attached to the skeletal structure in the sea after the skeletal structure is submerged. Even in this case, the attachment position is clear, which leads to an improvement in workability.

In each of the above embodiments, all of the plurality of pillars 4 erected on the skeletal structure 2 are provided with the seaweed seedling support 1.
Is described, but especially if it is not required to create a seaweed bed in a short period of time, zoospores that are attached to at least one of a plurality of pillars and released from mature seaweed there It is also possible to make the seaweed grow around through the seaweed.
One may be provided for each pillar. Furthermore, such as changing the supporting base and the locking body to another material or shape, or changing the shape of the non-applied portion and the method of forming the same when the mounting position of the seaweed seed carrier is specified by the algae paint. Various modifications within the technical idea of the invention are of course possible.

As described above, in the structure for creating a seaweed bed according to claim 1 of the present invention, the seaweed seed support is fixed to the pillar at the predetermined position on the outer peripheral surface of the pillar. Since it is configured to engage and engage, the locking body serves as a mark of the mounting position as it is, and the mounting work can be speeded up. Furthermore, since the seaweed seed carrier is engaged with the anchor via the locking body fixed to the pillar surface, the seaweed seed carrier on the seaweed seed carrier is not shifted from a predetermined position of the pillar. Settles on the surface of the pillars in a short period of time, and the seaweeds proliferate around it as a base point. Such a pillar can be manufactured inexpensively by eliminating the need for an expensive dedicated mold, since a separately manufactured locking body may be fixed to the surface of a pillar made of a general-purpose mold. There is no problem in strength because there is no. Furthermore, since the fixing position of the locking member can be selected at any position on the outer peripheral surface of the pillar, it is easy to cope with the case where the mounting position of the seaweed seedling support is changed according to design conditions.

Also in the case of the second or third aspect, similarly, each of the locking members serves as a mark for attaching the seaweed seedling support at a predetermined position, and is fixed to the pillar surface. The seaweed seed carrier is securely fixed at a predetermined position of the pillar by the locking body.

Further, according to the invention of claim 4 of the present application, the algal coating is applied to the outer peripheral surface of the column of the skeletal structure except for the position where the seaweed seed and seedling holder is to be attached, and the non-applied portion is applied. Since it is attached as a mark, the seaweed seed / seed carrier can be quickly attached to a predetermined position of the pillar in the same manner as in the above-described inventions. In particular, according to this configuration,
Seaweed seeds attached to the surface of the pillars have a coating layer of algae nourishing paint nearby, so they absorb nutrients contained in them and grow well, realizing seaweed bed development in a short period of time. .
