The perspective view of a breeding reef. Side view of breeding reef. The top view and bottom view of a breeding reef. Explanatory drawing of the modification of a breeding reef.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a breeding reef. FIG. 2 is a side view of the breeding reef. FIG. 3 is a top view and a bottom view of the breeding reef, where (a) is a top view and (b) is a bottom view.

  As shown in FIGS. 1 to 3, the breeding reef 1 of the present embodiment is submerged in the sea to propagate seaweed. The breeding reef 1 includes a base 10, a plurality of columnar members 20, an upper holding member 30, a side holding member 40, a fastener 50, and an anticorrosion net 60.

  The base 10 is the basis for the formation of the algae basin M surrounded by the anticorrosion net 60, and is composed of a material such as concrete that is so heavy that the algae basin sinks to the seabed, and the breeding reef 1 flows into the ocean current. Plays the role of weight to prevent. In order to increase the weight of the base 10, the height h (see FIG. 2) of the base 10 may be increased.

  Moreover, the leg part 11 is formed in the bottom face of the base 10 so that it may protrude with respect to the seabed. When the legs 11 are formed on the bottom surface of the base 10, the legs 11 are easily buried in the sea bottom due to the weight of the breeding reef 1, and the legs 11 are buried in the sea bottom, thereby preventing the breeding reef 1 from being washed away by the tide. To do.

  A through hole 12 is formed in the center of the base 10 for reducing the resistance of water when the breeding reef 1 is submerged. Further, a plurality of handles H for fishing with a crane or the like when the breeding reef 1 is submerged on the sea floor are fixedly disposed on the upper portion of the base 10.

  The columnar member 20 is erected on the upper surface of the base 10. In this embodiment, although the case where the number of columnar members is four was illustrated, it does not restrict to this. A structure for fixing the upper holding member 30 is provided on the top surface of the columnar member 20, and a holding groove 21 for fixing the side holding member 40 is formed on the side surface.

  The upper holding member 30 is fixed to the upper part of the columnar member 20 and holds the anticorrosion net 60 above the columnar member 20. The upper holding member 30 includes a top surface fixture 31 that is fixed to the top surface of the columnar member 20 and an upper posture holder 32 that holds the posture above the anticorrosion net 60.

  As the top fixture 31, L-shaped angle steel or the like can be used. The inner end portion of the top surface fixture 31 is fixed to the top surface of the columnar member 20 by a bolt, while the outer end portion is fixed to the upper posture holder 32 by welding. Since the top surface fixing tool 31 is disposed so as to extend from the columnar member 20 to the outer side of the seaweed basin M, the upper posture holder 32 is fixed to the outside of the columnar member 20, and as a result, more than the columnar member 20. The anticorrosion net 60 is held outside.

  The upper posture holder 32 is obtained by processing a steel pipe into a ring shape. The upper part of the seaweed bed M is covered by the anti-corrosion net 60 being hung on the upper posture holder 32.

  The side holding member 40 is fixed to the side portion of the columnar member 20 and holds the anticorrosion net 60 so that the anticorrosion net 60 is separated from the side of the columnar member 20. The side holding member 40 includes a side surface fixture 41 that fits in the holding groove 21 formed on the side surface of the columnar member 20, and a side posture holder 42 that holds the side posture of the anticorrosion net 60. The

  As shown in FIG. 2, the side surface fixture 41 has holding rings (upper holding ring 41 a and lower holding ring 41 b) that fit into holding grooves 21 formed at two locations on the side of the columnar member 20. Moreover, it has the extension part 41c extended from the upper holding ring 41a to the outer side of the seaweed bed M, and the connection part 41d which connects the extension part 41c and the lower holding ring 41b.

  The upper portion of the outer end portion of the extending portion 41c and the lower portion of the side posture holder 42 are welded, so that 41 and the side posture holder 42 are integrated. Thus, the side surface fixing tool 41 is composed of a plurality of members, and holds the side posture holding tool 42 in two upper and lower stages, so that the weight of the side posture holding tool 42 can be more effectively supported.

  The side posture holder 42 is obtained by processing a steel pipe into a ring shape. By applying the anticorrosion net 60 to the side posture holding tool 42, the posture of the side portion of the seaweed bed M is held.

  In the present embodiment, the side posture holder 42 is a member having the same size as the upper posture holder 32. That is, both the upper posture holder 32 and the side posture holder 42 are obtained by processing a steel pipe into a ring shape with the same size. If comprised in this way, if it attaches the top | upper surface fixing tool 31 to a ring-shaped steel pipe, it will become the upper holding member 30, and if it attaches the side surface fixing tool 41 to a ring-shaped steel pipe, it will become the side holding member 40, Therefore The versatility of 60 holders becomes high.

  The fastener 50 is a member for fastening the lower end of the anticorrosion net 60 to the surface of the base 10. Specifically, a plurality of bolts and the like for fixing the anticorrosion net 60 are provided at the lower end of the seaweed bed M.

  The anticorrosion net 60 is a net that prevents fish from entering the algae ground. The material is not limited, and it may be made of metal, synthetic resin, or fibrous. The size of the net of the net is not limited, and it is necessary to change it appropriately according to the type of seaweed to be propagated and the size of fish that prevents invasion.

  By comprising as mentioned above, the seaweed field M covered with the anti-corrosion net 60 is formed on the base 10, and the penetration | invasion to seaweed fields M, such as fish which eats seaweed, can be prevented. Moreover, if it is set as the structure which keeps the anti-corrosion net 60 spaced apart and hold | maintained to the side of the columnar member 20, the damage of the seaweed adhering to the columnar member 20 can also be prevented. For this reason, seaweed can be reliably propagated in the seaweed bed M and the columnar member 20.

  Further, when the upper holding member 30 and the side holding member 40 hold the anticorrosion net 60 in the outer direction of the seaweed bed than the columnar member 20, the seaweed bed M can be configured widely outside, and the columnar shape. The adhesion of seaweed to the member 20 can be promoted.

  Further, the upper holding member 30 is composed of separate members such as a top surface fixing tool 31 and an upper posture holding tool, and the side holding member 40 is composed of separate members called a side surface fixing tool 41 and a side posture holding tool 42. And the magnitude | size of the seaweed bed M can be changed easily by changing the magnitude | size of the upper attitude | position holder 32 and the side attitude holder 42. FIG.

  In the present embodiment, one side holding member 40 is used, but the present invention is not limited to this. In other words, a plurality of the columnar members 20 may be used depending on the length. FIG. 4 is an explanatory view of a modified example of a breeding reef. (A) is a breeding reef 2 configured to use two side holding members 40, and (b) is configured to use three side holding members 40. It is breeding reef 3. In FIG. 4, the anticorrosion net 60 is partially omitted.

  As shown in FIG. 4, when the length of the columnar member 20 is increased, the posture of the anticorrosion net 60 is held by using a plurality of side holding members 40. Thus, even when the long columnar member 20 is used to increase the height of the seaweed bed M, the posture of the anticorrosion net 60 can be maintained. As shown in FIG. 4, as the columnar member 20 becomes longer, if the height of the base 10 is increased, the weight of the base 10 increases, so that the posture of the high breeding reef can be stabilized. Can keep.
