Description

[Detailed Description of the Invention] This invention relates to an abalone reef, and relates to an abalone reef in which a plurality of reef plates are inserted into a frame mounted on a frame body.

In recent years, international restrictions have been added to the area of deep-sea fishing, and on the other hand, international efforts to ban whaling have been gaining momentum, and the environment surrounding fishing is harsh. Therefore, measures are being considered to actively promote coastal fishing. It has become clear that the construction of artificial fishing reefs on the seabed provides new habitats for fish and shellfish and greatly contributes to the promotion of coastal fisheries. Many fishing reefs have been sunk there, and the results of those experiments are still being studied.
Abalone reefs, where abalone live artificially, are one of the research topics. In the conventional abalone reef,
Concrete blocks or stacked flat plates were placed underground, so in order to harvest the abalone that lived on the abalone reef, one had to put on an aqualung and crawl into the sea to harvest them. Depending on the shape of the fruit, it was easy to harvest the upper tier, but it was often difficult to harvest the lower tier because it was difficult to reach. Additionally, there was a defect in that the upper stage was irradiated with sunlight, but the lower stage was not sufficiently exposed to sunlight. Another disadvantage was that abalones rarely live on the same abalone reef from young to adult.

The purpose of this invention is to provide a new abalone reef that eliminates the drawbacks of the prior art described above.

According to this invention, reef plates of different heights are inserted into the frame, making it easy to take floating or floating seaweed into the abalone reef. . In addition, the bottom of the reef body has a structure with a complex uneven space, which provides a perfect "hiding place" for abalone, and prevents octopuses and fish that eat abalone from devouring farmed abalone. In addition, it is possible to grow abalone from young to young to adult on one abalone reef.

This invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a partially cutaway perspective view showing the entire abalone reef 100 according to this invention. Abalone reef 100
consists of a frame 200 and a reef plate 300, and the frame 2
A plurality of reef plates 300 are inserted into the frame of 00 so that the whole is fan-shaped. In this embodiment, the abalone reef 100 is made of concrete, but its material is not limited to concrete, and may also be made of plastic or the like.

FIG. 2 is a perspective view of the frame 200 of the abalone reef 100 according to this invention. The frame 200 consists of two support plates 210 and two end clamps 230. The two end clamps 230 clamp the support plate 210 from the left and right, and the ends that abut each other are held by the fixtures 40.
It is fixed at 0 and forms a frame. Support plate 210
consists of a side surface 211 molded into a substantially fan shape, left and right pieces 212 and 213, upper and lower pieces 214 and 215, and a protrusion piece 216. Left and right pieces 212, 21
3 and the upper and lower pieces 214 and 215 are
The left and right pieces 212,
A screw hole 217 is bored in 213. Further, at the lower end of the side surface 211, a lower end projection piece 216 is provided at right angles to the side surface toward the inside of the reef body, and
It protrudes in an arc shape along the end face. A hanging hook (not shown) of a lifting crane for sinking the abalone reef into the sea is locked to the overhanging upper piece 214.

The end clamping base 230 is made of concrete,
It consists of an end face holding part 232 and a base part 234. The end holding portion 232 is formed into a rectangular plate shape, and has screw holes 217 of the support plate 210 at both ends in the longitudinal direction.
A screw hole 235 having the same diameter is bored. The base portion 234 is composed of a triangular leg, and is integrally provided on the outer surface of the end surface holding portion 232 at an equal distance from both ends in the longitudinal direction so as to protrude integrally with the end surface holding portion 232 . Since the platform 234 is heavy and is located at the four corners of the frame 200, the abalone reef 100 can be stably placed on the seabed.

3A and 3B are perspective views showing the entire reef plate 300. The reef plate 300 according to this invention consists of two types of reef plates 310 and 320 having different heights.
The reef plate 310 consists of a rectangular plate part 312 and a side plate part 316. The rectangular plate part 312 is formed into a semicircular shape with rounded upper and lower ends, and has a water passage hole 315 in the center thereof, and has suspension overhangs at both ends in the upper longitudinal direction. 314 has been extended. The suspension overhang portion 314 is formed to have an oval or circular cross section. The side plate portion 316 is formed into a tapered substantially pentagonal fan shape, and is provided protruding from both lower end surfaces of the rectangular plate portion 312 .
In the reef plate 310, the lower end surface 313 of the rectangular plate portion 312 is formed to protrude from the lower end surface 317 of the side plate. Like the reef plate 310, the reef plate 320 includes a rectangular plate part 322 and a side plate part 326.
The rectangular plate part 322 is formed into a semicircular shape with rounded upper and lower ends, and has a water passage hole 325 in the center thereof, and a suspension overhang part at both ends in the upper longitudinal direction. 324 has been extended. The suspension overhang portion 324 is formed to have an oval or circular cross section. The side plate portion 326 is
The rectangular plate portion 32 is formed into a tapered substantially pentagonal fan shape.
2, protrudingly provided on both end surfaces of the lower part. Reef plate 320
In this case, the lower end surface 323 of the rectangular plate portion 322 and the lower end surface 327 of the side plate are molded to have the same height.

In actual use, as shown in Figure 1,
The support plate 210 is held between the left and right sides by the holding stands 230,
The joint end is fixed with a fixture 400, and the frame 200 is fixed.
Configure. The frame 200 has a reef board 3 with a high board width.
10, and a reef plate 3 slightly lower than the reef plate 310.
20 are alternately inserted successively adjacent to each other from the end face holding plate 230. When inserting, insert the side end face 3 of the side plate part.

30, and lower end surfaces 317, 32 of the side plates.
7 is attached to the lower end projection piece 216 of the support plate 210, and the suspension overhang portion 314 is mounted to the upper piece 214 of the support plate 210. After inserting the reef plate 300 into the frame 200, concrete adhesive is poured into the gaps between the frame and the reef plates, and between the reef plates to strongly bond the entire abalone reef 100 into one piece. do.

In this embodiment, the side plate portions 30 of the reef plates 310 and 320 are arranged so that a total of 13 reef plates 300, including seven reef plates 310 and six reef plates 320, can be inserted.
6,326 angles and widths are set. However, it is not limited to this, and the side plate portion 3
It is also possible to increase or decrease the number of reef plates to be inserted by changing the angle of 16,326.
Furthermore, in this embodiment, the reef plates 310 and 32
0 and 0 are inserted alternately, but the invention is not limited to this, and may be inserted in other combinations.

When Abalone Reef 100 was sunk to the seabed, platform 2
34 is heavy and is located at the lower corner of the abalone reef 100, so it acts as a "weight" and allows the abalone reef 100 to be deposited in a stable state on the seabed. Furthermore, a reef plate 3 protruding from the frame 200
The top surface of 10,320 mm is shaped like an arc, so it has wave resistance. In addition, reef plates 310, 32
0 is inserted with the upper part of the rectangular plate parts 312, 322 and the suspension overhang parts 314, 324 protruding from the frame 200, so that the spores of seaweed floating in the sea are taken into the inside of the abalone reef. reef plate 310,
320, and can be constantly replenished with abalone food. Similarly, the reef plate 310,
320 is inserted vertically and diagonally into the frame 200, and the sunlight irradiating from the sea surface can be taken into the inside of the abalone reef 100.
It is possible to promote the growth of kelp and the like that have settled on the reef plates 310 and 320, and to supply sufficient food for abalone. Therefore, the abalone's food is eaten up,
There is no risk of the abalone being moved to another location, resulting in a ``rock-burning'' condition, and the abalone can be grown from young to adult shellfish suitable for harvesting on one reef. Furthermore, since there is a height difference between the reef plates 310 and 320, a gap 50 is created between adjacent reef plates. Therefore, Abalone Reef 100
When the abalone is deposited on the seabed, the abalone can freely move from the front surface to the back surface of the reef plate through the gap 50 created at the bottom of the abalone reef 100. Moreover, the presence of this space 50 also provides a suitable hiding place for the abalone to protect itself when attacked by fish, octopuses, etc. that feed on the abalone.

Since the abalone reef 100 according to this invention has the configuration as detailed above, more seaweed such as kelp that is food for abalone can be taken into the interior of the abalone reef 100, and the area for receiving sunlight is large. By promoting good growth, it is possible to constantly replenish the supply of feed to the abalone. In addition, since feed can be constantly supplied and replenished, the fishing reef does not become so-called rocky shore, and all abalones from young to adult can be kept safely on one reef. Furthermore, since the abalones remain safe until harvest time, the abalones do not move to other rocky areas, resulting in a stable harvest. Also,
By installing the abalone at a depth of 3 to 5 meters, it is possible to harvest abalone from a boat without diving into the sea, making it extremely efficient. It can be safely deposited on the seabed, and the rounded tips of the reef plates provide wave resistance.
