DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial octopus reef, which mainly provides a place to grow from laying eggs to hatching and young octopus and young octopus.

[0002]

2. Description of the Related Art As octopus has not yet been cultivated, a plurality of octopus urns are submerged in the sea as a means of constructing a breeding environment for octopus in order to increase and stabilize the continually decreasing amount of octopus being caught. That is widely done. Until recently, unglazed octopus pots, which are easy to adapt to the natural environment, were used.However, from the viewpoints of strength, durability, and cost, the inventor made octopus pots made of synthetic resin, concrete, metal, etc. paid to the water flow case such that, proposed a filler into between the octopus pot (pebbles, oyster shells, etc.) octopus reef (real equity No. 3-56206) filled with.

[0003]

The octopus reef proposed above has an octopus pot that hatches from spawning as a breeding environment for octopus.
The filling material was superior to the traditional octopus jar, as it provided water purification action, a space for growing young octopus and young octopus and a habitat for feed creatures, but it required labor and cost in manufacturing. Had disadvantages. In addition, the habitat space of the octopus jars was not of high quality, as each octopus jar was sealed and accumulated sludge.

When a large number of octopus jars are viewed as underwater structures for constructing a breeding environment for octopus, placing individual octopus jars directly on the seafloor means that the octopus jars are buried under the seabed, tidal currents, seine nets, etc. Since there are many inconveniences such as changing, it is preferable to construct a fish reef having the integration as proposed above. Further, it is preferable to replace the unbaked unoccupied octopus jar with a octopus jar made of steel, synthetic resin, concrete or the like by utilizing the water purification effect of the filler. In light of this, the marine fish reef proposed earlier was considered based on the experience of single-line fishing of octopus and long-term diving surveys on fish reefs and reefs.
We decided to develop an octopus reef suitable for spawning, hatching, growth of juvenile octopus and young octopus.

[0005]

As a result, what has been developed is that a shelter filled with oysters is provided on a base having legs, and an octopus urn having a through-hole on the bottom surface is provided on the base around the shelter. This is an octopus fish reef that is laid out so that it is not blocked.

A plurality of octopus pots are preferably provided on the base via a plurality of reinforcing bars inserted along a bottom surface having a through hole, and the reinforcing bars are provided with an octopus so as not to block the through holes in the bottom surface. It is advisable to fix the relative position of the octopus pot with mortar on the bottom of the pot. It is preferable that the shelter has a flange on the lower outer periphery fitted into an angle frame on a base and fixed with a mortar, and the upper surface of the shelter is pressed by a holding tool provided on the angle frame, or the holding tool is covered by the mortar. There are flat bars as the holding tools, and angles and steel plates as the holding tools.

The base is preferably made of polygonal steel or concrete, and is preferably provided with legs at each corner. However, the base is a steel frame assembled in a square shape and has base plates at four corners. It is preferable to use a substrate provided with The octopus pot is preferably made of steel, synthetic resin, concrete, for example, a horizontally long registrar leaf or the like having a plurality of through-holes on the side surface and provided with a plurality of through holes on the bottom face, but may be a conventional unglazed octopus pot.

[0008]

The octopus fish reef of the present invention is installed on the sea floor, and the octopus pot is fixed on the base with the legs separated from the sea bottom. Movement by a net or the like can be prevented. In addition, since the arrangement relationship of the plurality of octopus pots can be determined and confirmed on land and connected via a base, the entire arrangement can be installed underwater while maintaining the arrangement relationship.

In the shelter, the flange fitted into the angle frame on the base is fixed with mortar, and then the flange is indirectly pressed by a pressing tool covered with the mortar, for example, an angle, or is mounted on the angle frame. Presser,
For example, when the upper surface is pressed with a flat bar, it can be easily and firmly attached to the base. The mortar functions as a weight to stabilize the entire reef on the sea floor. The oysters filled in the shelter function as a growth space or a habitat for juvenile octopus and juvenile octopus and a habitat for feed creatures, and further have a function of purifying water quality around the fish reef.

[0010] The octopus pot is fixed on the base via a plurality of reinforcing bars inserted along the bottom surface, so that the through hole formed in the bottom surface is not closed even if the base is planar. In addition, on the base of the frame, the octopus pot can be floated from the sea bottom by arranging both ends of the reinforcing bar on the frame. The mortar that fixes the relative positional relationship between the octopus pot and the reinforcing bar also functions as a weight. The octopus urn secures water permeability inside and outside the octopus urn and discharges sludge accumulated in the octopus urn by the through hole on the bottom surface, and can maintain the environment, particularly cleanliness, in the octopus urn. By improving the environment of the entire reef, even if the octopus pot is made of a material that is strong but has poor affinity for living things, it is possible to provide an environment that is naturally harmonious with the entire reef.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an octopus reef 1 of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an octopus reef 1 in which a truncated pyramid shelter 2 is provided at the center of a rectangular base 3 and a total of 12 octopus pots 5, 6 are arranged around the shelter 2 with an opening 4 facing outward. FIG. 3 is a partially broken perspective view of the octopus urn 5 of the fish reef 1 alone, and FIG. 3 is a cross-sectional view of the fish reef 1 near the shelter 2.

The rectangular base 3 is a frame made of a steel angle, and has legs 9 to which the bottom plate 8 having the claws 7 is fixed to the lower end at the four corners as shown in FIG. Therefore, when the reef 1 is installed on the seabed, the bottom plate 8 is in contact with the seabed, so that stability is obtained, and the claws 7 may be hooked on the seabed, and may move under the influence of the tidal current and the seine net. Disappears.

The octopus urn (large) 5 is, as shown in FIG.
A horizontally long synthetic resin register leaf having an opening 4 on the side and a plurality of through holes 10 on the side and bottom surfaces. This octopus urn 5 is composed of two reinforcing bars 1
It is attached to the base 3 via 1,11. Octopus pot 5 and reinforcing bar 1
The relative positional relationship between the mortar 26 and the mortar 26 is determined by filling the bottom with the mortar 26 so as not to block the through hole 10.
Functions as a weight. A space is formed between the bottom of the octopus pot 5 and the sea bottom (since the rectangular base 3 of this embodiment is a frame, the octopus pots 5 and 6 have a space between the bottom and the sea bottom). The through holes 10 ensure water permeability inside the octopus pots 5 and 6, and the sludge in the octopus pots is discharged. The octopus urn (small) 6 is similarly attached to the base 3.

As shown in the side view of FIG. 3, the octopus urn 5 is formed by bending both ends of the reinforcing bars 11 and 11 so as not to block the through holes even on the planar base 22, for example, the concrete surface. The octopus pot 5 can be installed on the base 22, and the through hole 10 in the bottom of the octopus pot 5 ensures water permeability inside and outside the octopus pot. This water permeability is responsible for the inflow of fresh seawater required for octopus eggs laid in the octopus urn and the discharge of sludge and other substances that pollute the water quality. In this way, an environment suitable for octopus breeding, which has never existed before, is realized.

The shelter 2, as seen in FIG.
The entire surface is a truncated pyramid in which a net-like box is covered at the center of the above-mentioned square base 3 with an area of about 1/9. As shown in the sectional view of FIG. And fix the upper surface of the shelter 2 to the flat bar 13
It is held down and fixed. Alternatively, the shelter 23 may be fixed to the mortar 24 by covering another angle frame 25 which is a presser, as shown in the sectional view of FIG. The mortars 21, 24 function as weights for the entire fish reef. The oysters 14 filled in the shelters 2 and 23 not only purify the surrounding seawater but also inhabit feed organisms (such as crustaceans) necessary for the growth of juvenile octopus and juvenile octopus. Provide a growth space for

The octopus reef of the present invention can be freely configured and sized by a user when combining a shelter and an octopus urn on a base on land, so that the degree of freedom in installation can be secured. There is. FIG. 6 shows a shelter 16 and two octopus jars 17 each on the right and left sides on a rectangular base 15.
FIG. 2 is a perspective view of the marine fish reef 18 in which the squid is arranged. Since the octopus reef 18 requires a smaller installation area than that of the embodiment, it can be installed in a place where there is undulation on the sea floor due to a rock reef or the like.

[0017]

The octopus reef of the present invention has a base with legs, so there is no danger of being buried on the sea floor.
In addition, the entire fish reef becomes heavy due to mortar, etc., so that it does not move due to the effects of tidal currents and seine nets, and has an installation property that allows for integrated handling. In addition, the arrangement of the octopus urn and the shelter can be determined on land, and it has a versatility that can adopt various configurations, and it is possible to provide an appropriate fish reef according to a user's request. Another advantage is that all these members can be obtained at low cost.

A shelter provides a habitat or growth space for feed creatures, juvenile octopus, and juvenile octopus, and other fish (eg,
It is possible to create an environment that is very close to nature, for example, by enabling coexistence of sea cucumber with lobsters, rockfishes, scorpions, etc.). In addition, it has an effect of purifying the surrounding seawater, and has an advantage that the cleanliness until the hatching of the eggs can be secured.

Since the octopus pot has water permeability particularly through the through hole on the bottom surface, sludge does not accumulate inside the octopus pot, and permanent use while maintaining a clean space becomes possible. At present, when the number of octopus is drastically reduced and octopus cultivation has not yet been realized, it is desired to create a place where octopus can be sufficiently bred, and it can be said that the octopus reef of the present invention realizes this.
