る。<Prior art and its problems> It has already been established that spiny lobsters generally prefer to live in the spaces between stones formed by aggregation of multiple natural stones. Conventionally, a fish reef for spiny lobster has been developed as shown in, for example, Japanese Utility Model Application Publication No. 56-26562. The reef for spiny lobsters shown in this publication has a cubic frame made of H-beam steel, with narrow screen material on the upper frame and wide screen material on the lower frame. By storing a large number of natural stones in each frame and screen material, the upper cylindrical frame can be used for raising young shrimp, and the lower cylindrical frame can be used for raising parent shrimp.

好むこともわかつた。 However, further observation of the behavior of the spiny lobster revealed that it does not penetrate deep into the cave formed by the large number of natural stones, but always stays near the entrance. Further observation of the cause of this shows that when an octopus, which is considered to be the natural enemy of spiny lobsters, tries to attack the spiny lobsters, it appears that
It was also discovered that this was done to maintain a position that made it easy to jump out quickly. In addition, the material forming the space does not need to be natural stone, and the shape of the natural stone is important. I also learned that I like space.

Only the so-called surface layer, the inner natural stone portion, was completely wasted.

A plurality of gate-shaped concrete blocks are stacked with a space layer provided, and a plurality of natural stones or concrete blocks formed approximately in the shape of natural stones are housed in the hollow frame, and the plurality of natural stones or concrete blocks are stacked. The thickness of the empty layer formed by aggregation is reduced, but a large number of empty layers are formed to increase the storage area for spiny lobsters.

Reference numeral 1 is a frame body in which a hole 2 for the entrance and exit of the spiny lobster is formed, and this frame body 1 is hollow. It is formed as a set of two pieces so as to form part 3, and is formed in a cylindrical or gate shape as a whole. Further, the frame 1 may be made of concrete or iron, for example. A set of frames 1 formed in this way
A plurality of them are stacked by providing a space layer 4. 5
is a natural stone (chestnut stone) or a concrete block formed into a substantially natural stone shape stored in the hollow part 3 of the frame 1, and this natural stone 5 (or concrete block; the same shall apply hereinafter) is exposed to the outside from both sides of the frame 1. In order to prevent the spiny lobster from coming out, a frame (not shown) may be provided on both sides of the frame 1 with holes for the entrance and exit of the spiny lobster as well as water passage holes. 6 is frame 1
This vegetation material 6 is arranged on the outer peripheral surface of the
For example, it is constructed by using so-called artificial turf or by adhering seaweed spores to the artificial turf.

ることになるのである。<Function> Therefore, the spiny lobster enters the inside of the frame 1 through the entrance/exit hole/water passage hole 2, but this entrance/exit hole/water passage hole 2 is present on both the front and back sides of a pair of frame bodies 1. Therefore, you can freely enter and exit from either of them. The spiny lobster that entered through this entrance/exit hole/water passage hole 2 enters the cavity formed by the collection of natural stones 5 housed in the hollow part 3 of the frame 1.
That's where they make their home. This sky layer is 2
They are formed continuously within a set of frames 1, and the interval between two frames 1 is not planned to be very long, so for example, spiny lobsters that enter from the front side of frame 1 It is also possible to come out from the back. Since a plurality of the above-mentioned frames 1 are stacked on top of each other via the spatial layer 4, the movement of the spiny lobster to each frame 1 can be performed from the spatial layer 4 as well. In addition, when the frame 1 is made of iron, so-called iron ions are generated, which has the effect of promoting the growth of spiny lobster, and by providing the vegetation material 6, seaweed can grow from the frame 1. Not only is it possible to harvest seaweed such as kelp, but it also serves to hide the body of the spiny lobster from predators.

By creating layers and stacking them,
Since a plurality of natural stones or concrete blocks formed approximately in the shape of natural stones are housed in the hollow frame, the thickness of the hollow layer formed by the aggregation of the plurality of natural stones or concrete blocks can be reduced. However, by forming a large number of these empty layers, it has the effect of increasing the storage area for spiny lobsters.
