勾配を有するものが好ましい。In FIG. 1, four leg wall plates 1 are arranged radially, that is, in a cross shape in this case, with one end of each leg wall plate located at the center of a circle, and from near the upper end of each leg wall plate 1. A slope plate 2 having a downward slope is provided. The slope plate 2 is generally a flat plate with a four-sided shape, but a five-curved plate may also be used.As for the downward slope, it is sufficient that the slope is downward as a whole, for example, it may be a step-like downward slope. . 9. The slope of the slope plate 2 should be appropriately determined by taking into consideration the height of the leg wall plate 1, the horizontal spread of the fish reef block, the number and size of the through holes drilled in the slope plate 2, etc. Good luck, but
In view of the habits of spiny lobsters and the like, it is preferable that the slope be about 30 to 60 degrees.

宜選ぶことにより所望の奥行きとすることができるが。The slope plate 2 is provided with grooves 3 in a grid pattern on its surface.
A plurality of through holes 4 are drilled from the bottom of the groove to the back surface of the slope plate. Although the shape of the through-hole 4 is not particularly limited, it is preferable to have a through-hole cutter in the form of a slit, such as a horizontally long quadrilateral shape as shown in FIG. Further, the depth of the through hole 4 can be set to a desired depth by appropriately selecting the thickness of the slope plate 2.

ができる。Other methods include drilling the through-hole not perpendicularly to the surface of the slope plate but with a certain degree of inclination, and a method in which a cylindrical object is inserted into the through-hole even if the slope plate has a small thickness. The depth of the through hole can also be adjusted by employing the like.

ま念１種々の成長段階にある大きさの異なるイセエビ等
を対象とするという観点からは１貫通孔４は適宜大きさ
の異なる貫通孔を穿設したものが好ましく用いられる。Note 1: From the viewpoint of targeting spiny lobsters and the like of different sizes at various growth stages, it is preferable to use through holes 4 having different sizes as appropriate.

更に、脚壁板１にも表面から裏面に至る貫通孔を穿設す

させた態様も良好である。In Figure 1, grooves 3 are provided in a lattice pattern on the surface of the slope plate, and the presence of these grooves facilitates the movement of spiny lobsters etc. from one through hole to another, especially for escaping foreign predators. This has the advantage of making it easier to move around. Therefore, in addition to the groove configuration shown in FIG. 1, a configuration in which a sloped plate having a considerable thickness is used and one through hole is communicated with a tunnel type groove is also suitable.

また、斜面板０脚壁板共に必ずしも面構造である必要は
なく１例えば格子状などの骨構造であってもよい。Further, both the slope plate and the leg wall plate do not necessarily have to have a planar structure, but may have a bone structure such as a lattice shape.

The major feature of the embodiment shown in the figure is that the slope plate has a plurality of through holes, a flannel portion 2-a, and a frame portion 2 into which the panel portion is fitted.
-b, and the panel portion and the frame portion are configured to be detachable. The advantage of such a configuration is that the panel portion 2 can be replaced with a panel portion having an optimum through hole 4 as appropriate depending on the type of fish and shellfish such as spiny lobster to be used. Panel part 2-1 and frame part 2-b
As shown in Fig. 2, a typical fixing means is a nut embedded in one of the flannel part and the frame part in advance, and the other is tightened and fixed using a melt. Any fixing means, such as fixing them together, may be used.

んどみられない。(Operations and Effects) The fish reef block of the present invention has the following excellent effects as a fish reef block by adopting the above configuration. First, since the through-holes are drilled in the slope plate, an environment similar to that found in holes such as cracks on slopes of rocky areas, etc., which spiny lobsters and the like like, can be obtained. In addition, by drilling through holes of different sizes as appropriate, it is possible to target spiny lobsters, etc. at various growth stages. Due to the presence of the through-hole, a through-hole of an optimal size remains in either case, making it possible to cope with environmental changes over time. Furthermore, the existence of the through holes and the space between the slope plate and the leg wall plate makes it easy to protect against external enemies, and in the case where grooves are provided between the through holes, the through holes can easily escape from the external enemies and move easily. can. In addition, the presence of the five through holes allows for good water flow, and since the through holes are provided in the slope plate, sand and mud will not accumulate inside the through holes and cause blockages. In addition, the positional stability is good, there is relatively no directionality, and there is hardly any so-called netting such as fishing nets.
