In addition, many of these artificial reefs for the protection and rearing of young fish and for spawning are small reefs installed in shallow areas of the sea, and are made of concrete, which is cheap to manufacture and has become a monopoly.

However, in shallow waters, the influence of waves is greater than in deep waters, and the structure of the reef is required to be robust. For this reason, if they are made of concrete, it is necessary to make the members larger or to reinforce them with reinforcing bars to ensure strength, which results in disadvantages such as a smaller living space for fish and a smaller spawning area because the members are larger.

In addition, concrete construction requires temporary members such as formwork, and it takes about four weeks to reach the specified strength, and after installation in the sea, concrete scum occurs, and seaweed, which is said to be useful for fish, may be damaged for a long time. There is a risk that it will not stick to the surface.

Figure 1 is a perspective view showing one embodiment of the steel artificial reef of the present invention, Figure 2 is a front view of the same, and Figure 3 is a sectional view taken along line a-a' in Figure 2. A steel shelf plate 2 using a steel plate is a steel wall plate that maintains the distance between the steel shelf plates 1, and is fixed to the shelf plate 1 by welding perpendicularly. This steel wall board 2 starts from 1/2 of one side of the shelf board 1, crosses (or longitudinally) the center of the shelf board 1, and extends to 1/2 part of one side of the opposite side of the shelf board 1.
It is placed between the shelf boards 1, and the wall board 2 symmetrically closes about half of one of the side openings 8 between the shelf boards 1. Divide the interior space into two. Further, a through hole 3 was formed in the lower edge of the wall plate 2 by a horizontally long rectangular notch.

The through hole 3 may be a semicircular notch as shown in FIGS. 8 and 9, or may be a large number of small holes as shown in FIGS. 10 and 11. As an example, as shown in FIG. 12, the through holes 3 are provided only in the internal space partitioning part of the wall board 2, and the through holes 3 are not provided in the part that closes the opening 8 between the shelf boards 1. It is also possible to do so.

Then, as shown in FIG. 5, the first level of shelf boards 1 and wall boards 2 is set on the bottom plate 4 by penetrating and fixing the end of the shelf board 1 with reinforcing bars 6, and then The second layer is stacked, but at this time, the second
The wall plates 2 in the tiers are arranged with their orientations shifted by 90 degrees from the wall plates 2 in the first tier (see Fig. 6).

Incidentally, as shown in FIG. 3, if the left and right ends of the wall plate 2 are positioned so as to abut against the outside of the threaded reinforcing bar 6, the overall stability will be further increased.

Next, I will explain how to use the fish reef of this invention.
First of all, fish reefs are generally placed on the seabed, so it is desirable for them to be stable in any direction against horizontal forces such as tidal currents. Even "l"
The reaction force acts on this length and is stable.

In addition, when looking at the spawning of spear squid, it seems that they prefer places with relatively weak currents against the constantly changing currents due to tides, wind, etc., and they prefer places with relatively weak currents. The part indicated by diagonal lines E corresponds to this, and the part indicated by grid lines F corresponds to the flow as shown by arrow C. In this way, a safe zone for spawning can be secured against currents in any direction, and since the wall plate 2 changes by 90 degrees on each floor, a more stable action can be obtained, and the structure is more stable. The balance is also good.

As described above, the steel artificial reef of the present invention can be freely selected in shape and size from the viewpoint of the material, can be manufactured in a shorter period of time than a concrete reef, and can make effective use of factory space. In addition, there is no need for materials such as concrete casting forms for making fish reefs, and since attached organisms are attached immediately after the reef is placed, it has an excellent attracting effect for fish, and its dark black color is advantageous for raising squid eggs.
