Abstract

PURPOSE:To provide an artificial alga reef capable of efficiently rearing natural seaweeds on the sea bottom of a sandy place. CONSTITUTION:Waste tire (1) is sunk to the bottom of the sea by concrete (3) packed in the hollow part (2) of the tire (1) and artificial seaweed group (4) is circularly planted on the wall face in the circumference and stones (14) on which spores of natural seaweeds (15) adheres are charged into a center hole (13) for rim attachment of the waste tire (1) and these natural seaweeds (15) are reared in an area surrounded by the artificial seaweed group (4).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial algal reef and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, as a method for creating a natural seaweed reef in the sea of sand bottom near the coast, spores on which spores have been set up, concrete blocks, etc. are set in the sea and germinated and grown. is doing.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned conventional method for forming a natural reef, spores and juveniles germinated from the spores are separated from the epiphytic surface by tidal currents and waves, and the yield of seaweeds is increased. bad. Therefore, it is difficult to create a seaweed reef that collects seafood.

In view of the above, the present invention collects fish and shellfish because the spores that have settled and the larvae that have sprouted from the spores are not separated from the settling surface by tidal currents and waves and can be firmly attached and grow. The purpose of the present invention is to provide a seaweed reef that can be efficiently created at low cost and a method of creating the seaweed reef.

[0005]

In order to achieve the above object, the present invention attaches artificial seaweed groups in an annular shape along the circumference of an old tire in which a concrete is filled in the hollow portion, and attaches the rim to the tire. A stone in which natural seaweed spores have been deposited is filled in the center hole for use, and natural seaweed is grown in the area surrounded by the artificial seaweed group to form an artificial algal reef.

[0006]

EXAMPLE The old tire (1) is not limited to its size, and can be appropriately used from large tires for trucks to small tires for passenger cars. The method of filling the hollow (2) used as an air chamber around the tire (1) with the concrete (3) is to close the opening surface of the hollow (2) with a mold (not shown). Fill with fresh concrete and let it harden naturally. This concrete (3) acts as a weight sufficient to sink to the tire (1) and the seabed.

The artificial seaweed (4) which is annularly attached around the tire (1) is preferably a large one, and the one shown in the drawing is a knuckle-shaped one. It may be simply a strip.
As a method for attaching the artificial seaweed (4) around the tire (1), a hole (6) is formed in the wall surface (5) of the tire,
The base (7) of the artificial seaweed (4) is passed through this hole and wound around a rod-shaped stopper (8), or the threaded portion (11) of the connecting member (10) having a ring-shaped head (9) is attached to the tire ( 1) is screwed into the wall surface (5) and is tied to the head portion (9) through the base portion (7) of the artificial seaweed (4), or the wire member (12) is wound around the tire (1). Tie the base (7) of the artificial seaweed (4) to 12). The artificial seaweed group (4) attached in this way works so as to make the movement of the waves gentle compared with the inside of the enclosed area outside the area.

A central hole (1) for mounting a rim of an old tire (1)
Stone (14) that is put into 3) is preferably rubble stone in terms of cost,
Before the addition, spores (not shown) of natural seaweed (15) are settled.

Various kinds of natural seaweed (15) are used for feeding seafood and microorganisms, and those used for fishing for seafood, but in FIGS. 1 and 2, wakame seaweed is used. Is shown. This natural seaweed (15) is a stone (14)
Until the spores that have settled on the spores germinate and grow large, they are protected by a group of artificial seaweeds (4) around them.

As described above, the artificial seaweed (4) and the natural seaweed (15) which is grown by being protected by the seaweed form a seaweed reef or an undersea forest, and serve as a feeding place for microorganisms and seafood and a place for living. Provide and as a result collect seafood. In this way
A rich fishing ground can be obtained even if the seabed is sandy.

The old tire (1) has a mortar layer on its outer peripheral surface.
When (16) is provided by spraying etc., the spores of the natural seaweed (15) are likely to grow on the rough and uneven surface of the mortar layer, and natural seaweed is also formed on the outer peripheral surface of this old tire (1). growing up. Therefore, a seaweed reef that can collect more seafood can be obtained.

[0012]

INDUSTRIAL APPLICABILITY The present invention, as described above, uses old tires (1).
The hollow part (2) is filled with concrete (3), and artificial seaweed groups (4) are annularly attached along the circumference of the old tire, and a central hole (13) for attaching the rim of the old tire is provided. ) Is filled with stones (14) on which spores of natural seaweed (15) have been settled, and natural seaweed (1
5) Natural seaweed because it is configured to grow
The spores of (15) and the larvae sprouted from them are not separated from the epiphytic surface due to tidal currents and waves and can be firmly settled and grown, and an alga reef that collects seafood is efficiently created at low cost. It It also solves the problem of disposing of old tires.
