Description

  The present invention relates to a propagation block used for growing a root resource from juveniles to adults on the seabed, as well as to algae and fish as well as a root resource configured by using the root resource growth block. It relates to breeding reefs used for breeding.

Various breeding reefs have been proposed in the past for growing, breeding, and catching useful root resources such as abalone, shrimp, turban shell, sea urchin, and lobster. Among such breeding reefs, those with relatively simple structure are lobster breeding reefs that are installed in a multi-stage manner with a plurality of plate-like concrete plates with gaps of dimensions suitable for hiding lobsters (patents) Reference 1), and a relatively complicated structure is a concrete plate formed by combining a circular passage and a radial passage to the extent that a root resource can pass on a pedestal having a wide installation surface. The thing (refer patent document 2) which mounts the Sone resource breeding reef which becomes will be mentioned. The latter, in particular, is a stack of feed culture reefs that can cultivate plankton, etc. that feed the roots resources, and algae breeding reefs for growing algae, etc. As a result, it is possible to construct a multifunctional breeding reef that grows not only root resources but also feed biological algae and fish as a whole reef.

  In general, when cultivating sone resources, the sone resources are released into the sea when they have grown from larvae to juveniles with a length of several centimeters (abalones, tocobushi, turban shells, juvenile sea urchins, shrimp, etc.) However, the juveniles of released Sone resources are hidden in small gaps in the reef where they can not enter aliens such as octopuses and starfish that feed on them, and their bodies depend on the subsequent stages of growth. It moves sequentially in search of a wide space that matches the size of the. However, the Sone resource breeding reef, which is a component of the lobster breeding reef and the multifunctional breeding reef as described above, has almost uniform widths or passages formed in them. Although adults of resources are suitable for hiding themselves, they are too wide for hiding their bodies and can be easily caught by octopus legs and starfish, so that Sone resources are from young to adults It is not necessarily suitable for growing and settling on the spot. In addition, this type of breeding reef used by being submerged on the sea floor is usually made of concrete from the viewpoint of weight, durability, etc., but with huge concrete products manufactured using formwork, From the viewpoint of manufacturing accuracy and the like, there is a problem that it is difficult to form a small space suitable for the body length of the juvenile body. Furthermore, in the above-mentioned lobster breeding reef, if a plurality of concrete plates are alternately inclined and stacked, a gap is obtained in which one is narrowly opened and the other is opened wider. Although it is thought that it can settle in the place of the area according to the growth stage, as a real problem, it is very difficult to install such a huge concrete board on the seabed with good inclination.

  Therefore, in view of the above problems, the present invention forms a breeding reef that can form a hiding place of an appropriate size according to the growth stage of the Sone resource so that the Sone resource can settle for a long period of time. To provide a breeding reef suitable for the growth of not only rootstock resources but also other fish and algae. It is.

  That is, the Sone resource propagation block according to the present invention is a propagation block used for growing Sone resources such as abalone, Tokobushi, Sazae, sea urchin, lobster, from juveniles to adults, from a concrete block. The main body part is formed as a main body, a tapered surface inclined in one direction is formed on the outer surface of the main body part, and the outer surface having the tapered surface is faced to each other so as to be adjacent to the same kind of root resource breeding block. The entrance is narrow enough to allow the passage of the young plant of the Sone resource, and the exit is configured to form a wide Sone resource breeding space enough for the adult Sone resource to settle. To do.

  When a plurality of Sone resource breeding blocks having such a configuration are placed on the seabed in a state where they are arranged side by side, between the outer surfaces having the tapered surfaces of adjacent Sone resource breeding blocks, an inlet that opens narrowly on one side and a wide opening on the other side. A root resource growth space having an exit opening is formed. And by making the entrance side wide enough for the body length of the Sone resource juvenile and setting the exit side to a size suitable for the adult body length of the Sone resource, Between the bodies grow on the entrance side while protecting themselves from external enemies such as octopus and starfish, gradually move to the exit side according to the growth stage, and settle in this Sone resource propagation space, Since the roots grown in this way can be caught from the exit side, it is possible to obtain an excellent breeding reef that is suitable for the growth and multiplication of roots and that can maintain the fishing ground for a long time. It becomes possible. Furthermore, since seawater circulates through the Sone resource breeding space through the inlet and the outlet, fresh seawater can be supplied to the Sone resource. In addition, when manufacturing the Sone resource growth block as a concrete product, it is not necessary to form a narrow slit corresponding to the body length of the juvenile body in a single Sone resource growth block, and a tapered surface is formed on the outer surface. Since it is possible to form the above-mentioned root resource growth space between the adjacent root resource growth blocks, it is possible to easily manufacture such a root resource growth block. It becomes.

  When constructing the reef reef of the Sone resource using a plurality of such Sone resource breeding blocks, it is easy to create a Sone resource breeding space that gradually expands from the entrance side to the exit side as described above. In order to be able to form, the same kind of roots of the same kind arranged adjacent to the outer surface of the main body part on the inlet side of the root resource breeding space, substantially matching the width dimension of the root resource breeding space on the inlet side. It is desirable to form a protrusion that faces a portion of the outer surface of the main body portion of the resource breeding block that is the entrance side of the root resource breeding space. In other words, if the adjacent Sone resource multiplication block is arranged using this protrusion as a guide, the Sone resource multiplication block can be sequentially installed while forming an appropriate Sone resource multiplication space. In some cases, the protrusion can also function as a protection for the main body, so that the main body can be prevented from being damaged. In addition, as the shape of the protruding portion that functions as a smooth guide at the time of installation of the Sone resource breeding block and also helps prevent damage to the main body portion, in the main body portion of the same kind of Sone resource breeding block that is adjacently arranged at the top, Examples include a part-spherical shape facing the outer surface on the entrance side of the Sone resource breeding space.

  In addition, in order to stably install the Sone resource breeding block on the seabed and realize permanence as a breeding reef, it is better to attach the Sone resource breeding block to other members that are submerged on the seabed. It is done. As a configuration for that purpose, it is preferable to provide an attachment portion for attachment to another member at the lower end portion of the main body portion. Here, of course, for example, a large concrete block or a reef that serves as a pedestal corresponds to the other member. Corresponding block.

  Furthermore, in order to perform simple attachment of the soot resource breeding block, it is preferable that the attachment portion is a shaft member for axially attaching to another member. In this way, when the shaft member is applied as the attachment part, particularly when the root resource breeding block is stacked vertically to form a breeding reef as described above, the upper root of the main body part is placed on the upper root part. It is good to provide the bearing part for engaging with the shaft member of a resource multiplication block, and attaching in the state which mounted the said other root resource multiplication block.

  In addition, it is not restricted to the engagement relationship of such a shaft member and a bearing part, By providing the suitable receiving part for attaching in the state which mounted the other soot resource multiplication block in the upper end part of a main-body part, It is possible to stack the Sone resource breeding blocks up and down.

  In order to provide a suitable supply of feed and additional hiding places to the root resource, it is preferable to allow algae to grow close to the root resource growth block. An example of the soot resource growth block for easily realizing this is that in which an attachment portion for attaching an algae growth member for growing algae is formed on the upper end portion of the main body portion.

  In particular, considering the ecology of the Sone resource that moves from the small gaps of the reef to the seabed as it grows from juveniles to adults, and considering the convenience of manufacturing and installing the Sone Resource Growth Block, The tapered surface is inclined up and down on the outer surface of the main body so that the space has an inlet on the upper end side and an outlet on the lower end side, and the upper end side of the tapered surface is positioned outward from the lower end side. It is desirable to form as follows.

  Furthermore, in order for the Sone resource multiplication block itself to be able to supply the calcium components and the like necessary for the growth of Sone resources, as the concrete composition of the main body part, fly ash, clinker ash, fluidized bed ash, etc. It is good to contain coal ash. Coal ash is a large amount of waste discharged from thermal power plants, but effective reuse is being sought from the viewpoint of environmental conservation and waste disposal. Until now, fly ash that collected coal ash generated from a pulverized coal combustion boiler with an electric dust collector, clinker ash that crushed coal ash that fell to the bottom of the boiler, etc. have been mixed with cement as a concrete composition. However, the “fluidized bed ash (PFBC ash)” discharged from coal-fired power plants that use the pressurized fluidized bed combustion power generation system in particular is discharged by burning coal and limestone into a boiler. Since it is a coal ash, the content of calcium compounds is large, and when it reacts with water, it exhibits self-hardness, and therefore, its use as a substitute for cement has attracted attention. Therefore, if coal ash, which has been regarded as a waste material, is used as a raw material for the concrete ridge resource multiplication block, not only can the production price be reduced, but it can also provide new uses for coal ash. It will greatly contribute to the growth of the root resource growth block, which is the original purpose of the root resource growth block.

  Further, the propagation reef according to the present invention includes a plurality of sock root resource breeding blocks, and the adjacent soot resource breeding blocks are arranged in a plane so that the tapered surfaces formed on the outer surfaces thereof face each other. In addition, between these adjacent Sone resource propagation blocks, the entrance is narrow enough to allow the young plant of the Sone resource to pass through, and the exit is so wide that the adult Sone resource can settle. A space is formed.

  In the case of the Sone resource breeding reef having such a configuration, the Sone resource is appropriately grown from young to adult in the Sone resource breeding space formed between the plurality of Sone resource breeding blocks as described above and caught. In addition, it is possible to easily produce such a root resource growth block and to form a root resource growth space.

  In addition, examples of the plurality of root resource growth blocks suitable for forming such a root resource propagation reef include those having a generally square shape in plan view. By arranging them in order, an orderly breeding reef can be constructed in which the soot resource breeding space is efficiently arranged.

  Further, in order to obtain a root reed breeding reef having a multi-stage root reed propagation space, the same kind of reed root is placed on the upper surface side of a part or all of a plurality of reed blocks of a plurality of reeds arranged in a plane. It is preferable to attach the resource multiplication blocks in a stacked state.

  In addition, in order to allow the algae to grow and proliferate on this breeding reef while effectively using the upper surface side of the soot resource breeding block on which no other soot resource breeding block is placed, the upper surface side is opened. It is good to attach the algae growth member which grows algae to a root resource multiplication block. As described above, the algae that grows above the space for breeding the root of the root is a source of feed for the root and a good hiding place. In addition, if the algae growth member is detachably attached to the soot resource growth block, the algae growth member that has stopped functioning due to the algae dying, etc. By replacing it with an algae breeding member, new food and hiding place can be supplied to the soot resource. Moreover, when such an algae growth member is mainly composed of a concrete block, coal ash can be contained as a concrete composition, as in the case of the above-described sod resource growth block.

  In order to stably install the breeding reef on the sea floor as described above, the breeding reef is provided with a pedestal in which an arrangement portion capable of arranging and arranging a plurality of soot resource breeding blocks in a plane is provided. It is preferable to attach a plurality of soot resource multiplication blocks to the placement portion of the pedestal.

  In this case, in order to obtain a stable attachment state to the pedestal of the Sone resource multiplication block, a mounting portion for attachment to the pedestal is provided at the lower end portion of the main body of the Sone resource multiplication block, and the arrangement portion of the pedestal is provided. In addition, it is preferable to provide a receiving part for attaching the attachment part in a state where the Sone resource multiplication block is placed. Furthermore, in order to simplify the mounting operation and simplify the mounting structure, the mounting portion is a shaft member for axial mounting to other members including the base, and the receiving portion is engaged with the shaft member. What is necessary is just to set it as the bearing member for attaching in the state which mounted the root resource multiplication block in the arrangement | positioning part.

  Furthermore, a positioning part is formed on the pedestal for positioning and fixing the root resource multiplication block arranged at the end of the plurality of root resource multiplication blocks arranged in a plane on the arrangement part. It will be very easy to install the Sone Resource Growth Block. In particular, when the attachment member is a shaft member and the receiving member is a bearing member, the root resource growth block attached to the pedestal can be rotated to maintain the appropriate shape of the root resource growth space. Although there is a possibility that it may disappear, by fixing the root resource growth block at the end by this positioning portion, it is possible to suppress the rotation of all the root resource growth blocks aligned in a plane.

  In addition, it is preferable to install such breeding reefs on sandy ground and on the seabed where there are few gaps between the reefs and the existing seaweed beds necessary for the growth of root resources, but in this case, the pedestal should be installed stably. For this purpose, a plurality of legs that pierce the sandy ground on the seabed may be formed at the lower end of the pedestal.

  If such a leg part is formed on the pedestal, an arrangement part for installing the root resource breeding block is formed on the upper end part side of the pedestal, and on the inner side of the leg part on the lower surface side of the arrangement part, fish, For example, it is possible to form a fish reef space that is a hiding place for scorpionfish, Thailand, rockfish, and flounder that normally inhabit the reef. Therefore, in this breeding reef, in addition to the propagation of root resources, the growth of fish, or even algae It is also possible to increase the growth of In addition, the Sone resource breeding space and the fish reef space are connected to simplify the catch of the Sone resource grown in the Sone resource breeding space, and to secure a suitable tide to the Sone resource breeding space. In the upper part of the pedestal, an arrangement part is formed so as to form a parallel shape or a grid, and the soot resource breeding space has an inlet on the upper side and an outlet on the lower side in the arrangement part. It is suitable to arrange the breeding block so as to communicate the sone resource breeding space and the fish reef space vertically.

  In addition, in order to efficiently protect the root resources, algae, and fish and shellfish that grow on the breeding reef from other supplementary organisms, the breeding reef is protected by the root root resource breeding block, or the root root resource breeding block and the algal breeding member. Is preferably provided with a protective member having water permeability.

  The Sone resource breeding block of the present invention is formed by forming a tapered surface inclined in one direction on the outer surface of a main body made of a concrete block as a main body. By arranging adjacently so as to face each other, between the outer surfaces having this tapered surface, the entrance is narrow enough to allow the passage of the young plant of the Sone resource so that the adult of the Sone resource can settle A breeding reef that forms a wide space for breeding roots can be constructed. In such breeding reefs, it is possible to suitably breed roots such as abalone, mushrooms, turban shells, sea urchins, lobsters, etc. from juveniles to adults on the seabed, and to catch fish after growing. Suitable for use in root culture. In other words, the Sone resource breeding space formed between the plurality of Sone resource breeding blocks has a shape that opens narrowly on the entrance side and widens on the exit side. Inhabits and protects against external enemies such as octopus and starfish, and moves to the exit side as it matures, so it settles in the Sone resource breeding space for a long time until it is caught be able to. In addition, when each Sone resource breeding block is manufactured as a concrete product, a Sone resource breeding space is formed between adjacent Sone resource breeding blocks simply by forming a tapered surface on the outer surface of the main body. Therefore, it is not necessary to form a narrow slit suitable for the body length of the young body, and it can be easily manufactured. Furthermore, by attaching such a soot resource growth block to a pedestal installed on the seabed, or by attaching an algae growth member to the soot resource growth block, not only the soot resource, but also other seafood and algae Multifunctional and excellent breeding reefs that can also be obtained.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The present embodiment shown in FIGS. 1, 2 and 3 grows and grows root resources such as abalone, tocobushi, sazae, sea urchin, and lobster from juveniles to adults, and seaweed such as arame, swordfish, kurome and hondawala. This is a breeding reef 1 that is used by being submerged in the seabed for the purpose of growing sea bream (hereinafter, “algae”), and for the purpose of growing seafood such as scorpionfish, Thailand, sea bream, and flounder. The breeding reef 1 is a structure that is set on the seabed of sandy ground where no natural rocky zone exists, but is preferably installed on the sandy ground near the rocky zone that is already a good fishing ground. In this embodiment, the breeding reef 1 includes a root resource breeding block 2 whose main purpose is to grow and grow a root resource, and an algae breeding member 3 whose main purpose is to grow algae and form an algae field ( In the present embodiment, two types of algae growth members 3 ′ and 3 ″ are used, but when they are collectively used, reference numeral 3 is used) and installed on the seabed to support the root resource growth block 2 and the algae growth member 3 The pedestal 4 is provided as a main component.

  First, as shown in FIGS. 1 to 4, the Sone resource breeding block 2 has two types (2 ′, 2 ″) (hereinafter, generally referred to as reference numeral 2). These are mainly composed of a main body portion 21 made of a concrete block as a common configuration. As shown in FIG. 5 (a perspective view in (a) and a front view in (b)), the main body portion 21 is a regular quadrilateral whose lower surface 21b is substantially square and smaller than the upper surface 21a under a substantially square plate in plan view. It has a shape in which the truncated pyramid is continuous. That is, the main body 21 has four upstanding outer surfaces 21c, but the portion corresponding to the outer surface of the flat plate of each outer surface 21c is an upstanding surface 21d that stands up in a substantially vertical direction. A portion corresponding to the outer side surface of the regular quadrangular pyramid is a tapered surface 21e that is gradually inclined inward from above to below. Although the size of the main body 21 can be set as appropriate, in this embodiment, for example, one side of the upper surface 21a is about 500 mm, one side of the lower surface 21b is about 350 mm, and the overall height is about 350 mm (breakdown) The flat plate portion is about 100 mm and the regular square frustum portion is about 250 mm). Further, on the upper end side of the outer surface 21c of the main body portion 21, that is, on the two outer surfaces 21d adjacent to each other among the four standing surfaces 21d in the flat plate portion, the protruding portions 22 that protrude further outward are provided. In the present embodiment, for example, a concrete block having a hemispherical shape with a radius of about 30 mm is used as the protrusion 22, and the protrusion 22 is formed simultaneously with the manufacturing of the main body 21. In addition, although there is no restriction | limiting in particular in the number and position of the projection part 22 in the two standing surfaces 21d, in this embodiment, the two projection parts 22 are provided in the both ends and upper ends of the two standing surfaces 21d, respectively. Yes. In addition, a cylindrical bearing portion 23 is formed at the center of the upper surface 21a of the main body portion 21 as a receiving portion for mounting and attaching another root resource propagation block 2 ". In the case where no other root resource growth block 2 ″ is placed on the resource growth block 2 ′, hooks 25 are attached using the bearing portions 23, so that the root resource growth block 2 ″ is attached to the seabed. In addition, the center of the lower surface 21b of the main body portion 21 is provided with a pedestal 4 disposed below the root resource breeding block 2 '. A shaft member 24 is provided so as to protrude downward as an attachment portion for attachment to the other root resource breeding block 2.

In the present embodiment, for example, the algae growth member 3 ′ having a square shape in plan view with a side of about 200 mm (FIG. 6A) and the algae growth member 3 ′ having a rectangular shape in plan view with a long side of about 250 mm × a short side of about 100 mm are used. '(Fig. 6 (b)) has two types of shapes. In addition, the thickness of each of the algae growth members 3 ′ and 3 ″ is, for example, about 50 mm. Further, a through-hole 31 ′ having a thickness penetrating in the center of the algae growth members 3 ′ and 3 ″. , 31 ″, and the algal growth member 3 ′, 3 ″ are placed on the root resource growth block 2 ′ with the bolts 26 inserted through the through holes 31 ′, 31 ″. A resin-made butterfly nut 32 is screwed to the upper end portion of the bolt 26. Also, the concrete composition of the algae breeding member 3 is, for example, a weight ratio similar to that of the main body portion 21 of the root resource breeding block 2, for example, Powder (40% cement, 60% coal ash) and water 30% Such an algae breeding member 3 is mounted on the soot resource breeding block 2 ″ with no algae grown on the surface. You may try to land the algae spores and zoospores flowing into the tide The algae grown in advance in the sea or in the onshore water tank may be attached to the soot resource breeding block 2 ″ in a state in which the algae has been activated on the surface. In order to perform the above, the seed yarn to which the algae spores and zoospores are attached may be wound around the algae growth member 3. The shape of the algae growth member 3 is not limited to the above-described one, for example, on the upper surface. Concavities and convexities can be formed, and the algae can be easily rooted and settled.

  The pedestal 4 is a large concrete structure having a size and a weight that can maintain a stable installation state over a long period of time on the seabed. Specifically, as shown in FIG. 7, the pedestal 4 has, for example, a frame-shaped main body 41 having a hexagonal shape in plan view, and a total of six protruding from the six corner portions of the frame-shaped main body 41 obliquely downward and outward. The leg part 42 of a book and the crosspiece 43 passed between a pair of inner side surfaces of the frame-shaped main body 41 are manufactured integrally with cement, aggregate, and water as a concrete composition. Here, the height dimension from the lower end of the leg portion 42 to the upper end of the frame-shaped main body 41 is, for example, about 900 mm, and the lower end of the frame-shaped main body 41 is still higher than the seabed even if the leg portion 42 pierces the sand ground on the seabed. To be positioned. Further, four horizontal bars 43 having the same thickness as the frame-shaped main body 41 are provided in parallel at predetermined intervals, and a slit 4s having a width of, for example, about 80 mm is provided between the horizontal bars 42. Is forming. Each of the horizontal rails 43 functions as an arrangement unit for arranging the root resource breeding block 2, and a plurality (in the illustrated example, 4 in the illustrated example) are arranged in a straight line as the arrangement position of the root resource breeding block 2. And the bearing member 44 as a receiving part for receiving and fixing the shaft member 24 of the root resource breeding block 2 so as to communicate with each hole 43a. It is embedded in the crosspiece 43. Here, as the bearing member 44, as shown in FIG. 8, a bowl-shaped bearing main body 44a provided with a plurality of spring washers 44b for engaging the shaft member 24 inserted therein so as to be difficult to be removed is a disc-like shape. What was embed | buried in the crosspiece 43 with the reinforcement board 44c and the anchor reinforcement 44d is employ | adopted. In addition, on the upper surface of the frame-shaped main body 41 located outside the horizontal rails 43 at both ends, it is arranged at the end of the plurality of root resource breeding blocks 2 to be arranged on the horizontal rails 43 as will be described later. Four positioning portions 45 are provided for positioning and fixing the root resource breeding block 2 "to be used. These positioning portions are frame-shaped main bodies in a state where the L-shaped steel material is erected so that the inner angle side faces inward. In this embodiment, such a pedestal 4 is manufactured using a predetermined formwork at the seaside near the sea where the breeding reef 1 is installed.

  Each part having the above configuration is installed in the sea as follows to form the breeding reef 1. First, after the pedestal 4 is manufactured, the Sone resource multiplication block 2 is suspended to the pedestal 4 sequentially with a crane on the land, and the shaft member 24 is inserted into the hole 43a formed in the horizontal rail 43 of the pedestal 4 from above, The shaft member 24 is engaged with the spring washer 44 b of the bearing member 24. At this time, in the present embodiment, four holes 43a and bearing members 44 are provided in the four horizontal bars 43 at equal intervals in the front, rear, left, and right directions. 2 are arranged in a substantially square grid shape. Here, on each of the 16 root resource propagation blocks 2 among the 16 root resource growth blocks 2, another root resource growth block 2 is placed on each of the four root resource growth blocks 2, and the letter B in plan view. Since the algal growth member 3 is placed on the 12 outer periphery side root-bone resource growth blocks 2 forming the mold, the root-resource growth block 2 'having the basic structure is applied to the inner four. , The root resource propagation block 2 "provided with the bolts 26 is applied to the outer twelve. Further, the upper four parts placed on the root resource propagation block 2 'are the root resource propagation blocks. Block 2 "is applied. Regarding the arrangement order of the 16 roots of the ridge resource multiplication block 2 on the lower side, for example, the ridge resource multiplication block 2 ′ at the upper left side of the page shown in FIG. It is better to install the Sone resource multiplication block 2 ′ or Sone resource multiplication block 2 ″, which will be adjacent to each other, in order so that they face each other. When the next Sone resource multiplication block 2 is arranged next to the Sone resource multiplication block 2 already installed on the horizontal rail 43, the hemispherical protrusion 22 in the Sone resource multiplication block 2 already installed becomes In addition to exhibiting a function for securing a space between the root resource breeding block 2 and functioning as a guide to a predetermined arrangement position of the adjacent root resource breeding block 2, it is also used for preventing damage to the main body 21. As a protector And thus the ability. Further, it is sufficient Similarly for Isone resource proliferation block 2 "of the upper side. A plurality (20 in total) of the soot resource breeding blocks 2 arranged in this manner are arranged in a grid shape in plan view. Due to such an arrangement, even if a horizontal rotational force centering on the shaft member 24 and the bearing member 44 acts on the Sone resource breeding block 2, the Sone resource breeding block 2 Since the deterring force against rotation works by abutting against the protrusion 22, the grid-like arrangement is not disturbed. In particular, among the root-side resource growth blocks 2 on the lower stage side, the four root-stock resource growth blocks 2 "arranged at the corners are positioned by the positioning unit 45 and are fixed so as not to rotate horizontally. In addition, in the state where four algae-growing members 3 ′ having a square shape in plan view are mounted on the root-side resource growth block 2 ″ on the outer peripheral side on the lower stage side, In the state where four algae-growing members 3 "having a rectangular shape in plan view are placed on the root-resource-growing block 2", butterfly nuts 32 are screwed onto the bolts 26, so that each algae-growing member 3 is Fix it. In addition, you may make it fix the algae growth member 3 to the pedestal 4 of the seabed in the state where the soot resource growth block 2 "was attached in advance. After installation, it is placed on a trolley etc. and transported to the sea area where the breeding reef 1 is installed, and is sunk on the seabed.

  In the breeding reef 1 installed on the seabed in this way, as shown in a partially enlarged view in FIG. 9, between the outer side surfaces 21c composed of the rising surface 21d and the tapered surface 21e of the adjacent soot resource breeding block 2 There is a trumpet-shaped space that is narrowly opened upward and widened downward, and in this embodiment, this space is defined as a root resource breeding space S1. The opening width on the upper end side of the soot resource breeding space S1 substantially coincides with the protruding length (about 30 mm) of the protruding portion 22 from the main body portion 21, and the opening width on the lower end side is an opposing tapered surface 21e. It corresponds to the distance between the bottom edges of Further, the Sone resource breeding space S <b> 1 communicates with a slit 4 s formed between adjacent horizontal bars 43 of the pedestal 4 on the lower end side. Furthermore, although the lower end side of the leg part 42 of the base 4 is pierced into the sand ground of the seabed SB, it is raised by the height of the leg part 42 and the lower surface of the horizontal rail 43 is positioned so as to float from the seabed SB. A space that is low in height but spread in the horizontal direction is formed between the lower surfaces of the frame-shaped main body 41 and the horizontal rail 43 and the seabed SB inside the plurality of leg portions 42. In the present embodiment, this space is used as a fish reef space. S2. That is, the Sone resource breeding space S1, the slit 4s, and the fish reef space S2 are integrated with each other, and seawater flows up and down in this continuous space.

  Such a breeding reef 1 is an adult from a juvenile body of a sock root resource (for example, abalone A1, sea bream A2, sea urchin A3, lobster (not shown), etc.) using the sod resource breeding space S1, the slit 4s and the fish reef space S2. , Growth of algae B using the algae growth member 3 (for example, arame, kajime, kurome, hondawala, etc.), formation of algae basin by growth and growth, seafood (for example, flounder C1, other fish C2) using the reef space S2, etc. Etc.) is possible. For example, when this breeding reef 1 is used for abalone A1 culture, if the abalone juvenile A1a grown to a length of about 3 cm is discharged from the breeding reef 1, the juvenile A1a has a space that fits its own length. , And enters the root resource breeding space S1 through the opening on the upper end side, and adheres to the rising surface 21d on the upper end side in the main body portion 21 of the root resource breeding block 2. In this way, if the opening is on the upper end side of the narrow ridge resource breeding space S1, the larvae A1a can easily enter using it as an entrance, but it is too narrow for external enemies such as octopus and starfish to compensate for the larvae A1a. Since they cannot eat, the larvae A1a can grow safely in the Sone resource breeding space S1. The abalone A1b moves downward toward the tapered surface 21e of the main body 21 as the body length grows and the abalone A1c that has grown to adulthood settles in the slit 4s between the cross rails 43 and the reef space S2. become. The slits 4s and the reef space S2 are large enough for humans to reach their hands, so that the adult abalone A1c can be caught. Further, although not described in detail, the same can be said for sour root resources such as tuna shrimp A2, sea urchin A3, and other lobsters. In addition, the coal ash included in the concrete composition that is the main material of the Sone resource breeding block 2 contains a large amount of calcium component, so if it exudes into the sea, it will help the growth of Sone resources. . In addition, a large amount of plankton is collected on the algae growth member 3 on the root resource growth block 2 because the algae B grows to form an algae field, and this feeds the root resource and small fish C3. The algae can also be a good hiding place for small fish C3. If algae B has died, the algae growth member 3 may be removed from the root resource growth block 2 and replaced with a new one. Furthermore, the reef space S2 and the slit 4s, which are relatively large spaces, serve as a hiding place for small or medium-sized seafood. A great habitat. Thus, the breeding reef 1 of the present embodiment greatly contributes to the establishment of a good fishing ground by breeding root resources, algae, and seafood.

  In order to prevent the root resources, algae, and seafood that grow, multiply, and settle on the breeding reef 1 of this embodiment from being damaged by relatively large supplementary organisms, What is necessary is just to cover the algae growth member 3 with protective members which have water permeability, such as a cage | basket, a net, and a fence. As an example, the protective member 5 shown in FIG. 10 has four pillars 51 standing on the frame-like main body 41 of the base 4 and a frame is formed by passing a crosspiece 52 between the pillars 51, and a fence 53 is formed on the frame. It is attached. By doing in this way, internal root resources, algae, and seafood can settle more safely in the breeding reef 1.

  The present invention is not limited to the embodiment described above. For example, it is possible to construct a breeding reef from only a plurality of root resource breeding blocks, or to construct a breeding reef from a plurality of root resource breeding blocks and an algal breeding member. In these cases, the Sone resource breeding block may be installed directly on the seabed or on a natural reef. In addition, various modifications can be made without departing from the spirit of the present invention with respect to the specific shape and configuration of the root resource growth block, the algae growth member, the pedestal, and other specific components.
