Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial fish reef suitable for breeding fish and shellfish and seaweed, especially Japanese spiny shrimp, by fully colonizing them.

Ise! 11! J:; and sacs, including the dens, occur from the Boso Peninsula on the Pacific side of Japan to the southern part of Bonyo, and they all have similar habitats in that they live in the Tatami C1 zone.

The inventor was located in Muroto City, Kochi Prefecture, and conducted an actual diving survey of Ise-Ebi-o and the rocky reef area east of it. As a result, Ise shrimp prefer hollows in rocky reefs that are slightly higher than the ocean floor, where seawater flows without stagnation, and where they can escape up, down, left and right, and where there is plenty of sunlight. I realized that any place where N algae grows would be a perfect habitat. Also.

I learned that they prefer places with almost the same conditions as Ise shrimp, as long as there are secret places where they can hide.

This paper presents a proposal based on this knowledge, and will explain its details based on drawings. .

A large number of circular shelves 1 made of concrete are connected in a horizontal position through a columnar support 112 located at the center, with appropriate spacing between the upper and lower sides. Gaps 3 for fish habitat were formed around the entire circumference. Imomoto composition. The diameter of the upper circular shelf 1 is smaller than that of the upper one.

Down the circular outer peripheral side of each column 1 (formed on the tapered surface of 'Q g4, and at the diagonal position of each column 1, there are cut-out holes 4 that reach the outer circumferential surface of the support column 2 and are vertically aligned. do.

5. It is recessed and decorated. ,,.

Incidentally, in terms of the preferred dimensions of each part when the main purpose is to establish a habitation of Ise shrimp, the outer diameter of the circular shelf 1 below the lobster should be approximately 200 cm.
m, the outer fZ of the topmost circular shelf 1 is approximately 140 cm, and the support post 2
The outer diameter of is approximately 5', Qcm, and the vertical height of gap 3 is approximately 24cm.
m, the width of the moxibustion cutter 4 is about 20 cm.

In such a case, when the lowest circular shelf 1 is submerged in the sea so that its flat bottom surface touches the seabed, the gap 3 is
Because it has an annular shape surrounding the gap 3, seawater can circulate smoothly within the gap 3.

It also flows up and down via the notch 4. In addition, because of the presence of the notches 4, there is moderate sunlight from the upper circular shelf 1 to the lower circular shelf 1, so there is seaweed especially around the notches 4 on the top surface of each column l. It is well established and flourishes. With this seaweed colonization, each gap 3 becomes moderately dark. And one lap groove 5
It is also possible to actively plant seaweed bacteria. As a result, each gap 3 becomes a perfect habitat for the spiny shrimp, and the spiny shrimp moves around in all directions on each shelf 1, and uses the notches 4 between the upper and lower circular shelves 1 and 1. I can do it myself, move to the heart, -□. In addition, the gap 3 between the two becomes a home for rockfish. Furthermore, the bags containing the cavities are fixed in the lower surface of each column 1, particularly in the lower surface 1 and the circumferential groove 5.

□ In addition, FIG. 3 shows another embodiment of the present invention, in which holes 6 that penetrate vertically through each circular shelf 1 are formed vertically in series with the same phase instead of the notches 4. The remaining points are substantially the same as those of the above embodiment.

In addition, there are methods in which the first group of shelves and the through support columns 2 are molded separately and joined together instead of being molded as one piece with concrete 1, or they are molded after being divided into multiple stages vertically and then molded. A method of stacking and connecting them can also be adopted.

As explained above, in the present invention, a large number of circular shelves 1 are connected in a horizontal posture with appropriate intervals vertically via the pillars 2 located near the center, and fish can be placed between each circular shelf 1. Habitat room 8i3 is formed. Therefore, a large number of fish habitat rooms were sectioned. Compared to the so-called fish apartment type, the movement of seawater in the gap 3 is better, and the creatures can move laterally (therefore, fish prefer this type of environment. It is suitable for established breeding.In addition, the bottom surface of each column 1 is particularly suitable for cultivating bags.

It is formed small. Therefore, the outer circumference of the upper surface of all the circular shelves l and the side surface of the circular outer circumference that follows it are well-hit, and the seaweed is established and grows thickly in the corresponding area.Especially, on the outer circumferential side of each column 1, Forming the Wandering Spirit 5,'
The □ also actively settles and grows in sufficient numbers on the circular outer circumferential side surface as uniformly as possible. As a result, these seaweeds and fish were attracted, and each gap 3 was not specified more than necessary.

It becomes a suitable place for fish to live, and the present invention has a great practical effect in this respect as well.
