然の岩礁帯は、このような条件を具備するイカの産卵に
適した場は少ない。It is generally known that squid often spawn on the underside of boulders on the ocean floor, on the ceilings of rock ledges and rock crevices. In particular,
The place where many eggs are laid is the ceiling 1n1 of a relatively narrow space with an opening height of about 20 to 50 cm. In addition, it is important that the environment is clear and has good tidal flow. However, there are few natural reef zones that have these conditions and are suitable for spawning squid.
本発明は、これらの背景のもとに、イカ等の産卵場など
の造成に供するに適し、海底設置の安定性も良好な魚礁
ブロックを提供するものである。すなわち、本発明は、
平面天板の中央部に平面天板の面積の１０〜３０％に相

１１ｊ面に平面天板中央部を中心として放射状に脚部が
垂設されている魚礁ブロックである。With these backgrounds in mind, the present invention provides a fish reef block that is suitable for creating spawning grounds for squid and the like and has good stability when installed on the seabed. That is, the present invention
A through hole with a width equivalent to 10 to 30% of the area of the flat top plate is provided in the center of the flat top plate, and a through hole is provided at the bottom of the flat top plate.
This is a fish reef block with legs hanging radially from the center of the flat top plate on the 11j surface.
第１図は本発明の魚礁ブロックの代表的実施態鴎を示す
斜視図である。FIG. 1 is a perspective view showing a typical embodiment of the fish reef block of the present invention.
平向天板１の中央部に平面天板１の面積の１０〜３０％

うに深さの浅い溝部が多数存在するような平面であって
もよい。10 to 30% of the area of the flat top plate 1 in the center of the flat top plate 1
A through hole 2 having a width within the range of is provided. The top plate 1 needs to be a flat top plate in order to form a flat ceiling surface with good water flow, which is preferred by squid. However, it only needs to be flat as a whole, and the surface does not necessarily have to be smooth. For example, it may be a flat surface with many shallow grooves so that laid eggs can easily land there. .
通孔２は潮通しを良好にするためにＩｉ！である。通孔
部の面積が平面天板１の面積の１０％未満の場合は潮通
しが不十分となり、また３０％を超える場合は、産卵に
適した安定した雰囲気の天井面が得られ難い。Through hole 2 is designed to improve drainage. It is. If the area of the through hole is less than 10% of the area of the flat top plate 1, drainage will be insufficient, and if it exceeds 30%, it will be difficult to obtain a ceiling surface with a stable atmosphere suitable for spawning.
平面天板１の形状は特に制限されないが、ある程度の変

どの正多角形状平面天板の場合は、魚礁ブロックを海底
に設置する際に方向性がなく沈設が容易で設置後もあら
ゆる潮流に対応できる利点も存する。The shape of the flat top plate 1 is not particularly limited, but in order to provide a certain degree of variation and to form a spawning place with uniform conditions throughout, it is preferable to have a regular polygonal flat top plate, particularly a regular hexagonal flat top plate. A shaped flat top plate is preferred. In the case of a regular polygonal flat top plate such as a regular hexagonal shape, there is no directionality when installing the fish reef block on the seabed, making it easy to sink, and it also has the advantage of being able to respond to any tidal current after installation.
通孔２の形状も制限はされないが、全体に均一な条件の
天井面を形成するためには、平面天板の形状と相似形の
正多角形状の通孔とし、かつ、両正多角形の対角線が重
なるように設けられるのが好ましい。There is no restriction on the shape of the through hole 2, but in order to form a ceiling surface with uniform conditions throughout, the through hole should be a regular polygon similar to the shape of the flat top plate, and both regular polygons should be formed. It is preferable that the diagonals are provided so that they overlap.

れる。Further, it is necessary that the legs 3 are vertically disposed on the lower surface of the flat top plate 1 in a radial manner centered on the center of the flat top plate. It is desirable that the leg portion 3 is a plate-like leg portion. By hanging the plate-shaped legs 3 radially on the lower surface, the flow flows into the through hole 2 from one direction of the flat top plate 1 and flows out radially on the lower surface of the flat top plate 1, or in the opposite direction. A flow passage is obtained.

In this case, normally the plate-shaped leg portion 3 does not extend to the portion where the through hole 2 is present. Further, the plate-like leg portion 3 may be provided with holes for water passage in the horizontal direction as appropriate.

る方が、魚礁ブロックの設置安定性が良好である。FIG. 2 is a perspective view showing another embodiment of the fish reef block of the present invention. In this aspect, the legs 3 are provided to extend radially to the periphery of the flat top plate 10, and the lower portions of the adjacent plate-shaped legs 3 are connected to each other by connecting members 4 along the periphery of the flat top plate 10. By connecting the legs 3 with the connecting members 4 in this way, the mechanical strength of the legs 3 vertically installed on the flat top plate 1 is greatly improved. In particular, it is effective to provide this connecting member 4 when the number of plate-shaped legs 3 is small and the height is high, or when the seabed at the place where the main fish reef pod is deposited is uneven and the tidal current is strong. The connecting member 4 may span not only the portion along the periphery of the flat top plate 10 but also the entire lower part of the plate-like leg portion 3. However, since the seabed where spawning grounds for squid etc. are created is usually uneven, it is better to install the connecting material 4 only in the area along the periphery of the flat top plate l, which will improve the installation stability of the fish reef block. is good.

の漸進１２通路が得られる。FIG. 3 is a perspective view showing yet another embodiment of the fish reef block of the present invention. That is, in this embodiment, several stages of reef blocks shown in FIGS. 1 and 2 are stacked. The present invention also provides a reef block constructed by stacking the single-stage reef pulls (hereinafter also simply referred to as reef boot units) of the present invention as described above to form an integrated whole. The most preferred embodiment of the present invention is one in which several stages are stacked like this. By stacking them in this way, the water passage which is most desired as a breeding ground for squid soup becomes extremely good. In other words, it flows into the through hole 2 from above the reef block unit stacked in the L-most stage, and flows out radially from the gap between each reef block unit formed by the hanging legs 3, or vice versa. Twelve progressive passages of directional flow are obtained.

ツクユニットを採用した実施態様である。As a stackable fish reef block unit, a through hole with a size corresponding to 10 to 30% of the area of the flat top plate is provided in the center of the flat top plate, and a hole in the center of the flat top plate is provided on the lower side of the flat top plate. It is not particularly limited as long as it is a fish reef plutsuku with legs hanging radially from the center. However, as a preferred embodiment, as shown in FIG. 3, the bottom fish reef block unit is a fish reef in which the lower parts of adjacent plate-shaped legs are connected to each other by a connecting member along the periphery of the flat top plate. This is an embodiment that employs a pull unit.

めつげる方法なども適宜採用することができる。By doing this, it is possible to provide the bottom fish reef block unit with legs that have sufficient mechanical strength against the weight of the stacked fish reef boot block units and the unevenness of the submerged seabed. . Further, it is desirable that the respective reef block units be appropriately fixed using bolts and nuts, for example. For this purpose, for example, a nut may be embedded in advance in the plate-like leg portion and the flat top plate, and a metal member having a bolt hole may be used to secure the two. In addition, there is a method in which through-holes are provided in a straight line in the fish reef pull unit from the top to the bottom, and reinforcing bars are passed through the holes and tightened from above and below, or there is no need to provide any through-holes.
A method of sandwiching and tightening the reef block units from the uppermost stage to the lowermost stage around the outer periphery of the reef block or the inner periphery of the through hole can also be adopted as appropriate.
