〔産業上の利用分野〕
本発明は、海中、淡水中に設置して魚を集める人工魚礁
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an artificial reef installed in the sea or fresh water to collect fish.
従来、人工魚礁としては、方形コンクリ−１・のブロッ
ク体や古いタイヤを組合わせたものや、廃パスを海中に
投棄するものがある。Conventional artificial reefs include those made by combining rectangular concrete blocks, old tires, and those made by dumping waste paths into the sea.
（発明が解決しようとする問題点〕
しかし、これら従来の魚礁は、重量が大きいので、−旦
設置すると移動が困難で、このため海域の環境条件の悪
化に対応できず最適な魚礁位置の選定ができないことが

これらの作業が大がかりなものとなり費用もかさむ。(Problems to be Solved by the Invention) However, these conventional fish reefs are heavy and difficult to move once installed, making it impossible to cope with deteriorating environmental conditions in the sea area, making it difficult to select the optimal reef location. In addition, it is difficult to quickly respond to aging fish reefs.Furthermore, large work boats are required for transportation and installation.
These operations become large-scale and cost-intensive.
さらに、古タイヤや廃パスを用いる場合はもちろんのこ

状が限定されるので、複雑に立体化した魚礁を得ること
がむずかしく大きな魚礁効果が期待できない。Furthermore, not only when old tires and waste passes are used, but even when rectangular concrete blocks are used, the shape is limited, so it is difficult to obtain a complex three-dimensional fish reef, and a large fish reef effect cannot be expected.
また、魚礁自体は魚を捕獲する手段を有しないので、捕
獲量には限界がある。Furthermore, since the fish reef itself does not have the means to catch fish, there is a limit to the amount of fish that can be caught.

該魚礁本体に重量調節装置と捕獲網とを設けることを要
旨とするものである。The purpose of the present invention is to eliminate the disadvantages of the conventional example, to reduce the weight of the fish reef, to make it easy to move and install, to increase the fish-building effect, to increase the amount of fish caught, and to make it possible to reduce the weight of the fish reef. The present invention aims to provide an artificial reef that can be used for research on fish reefs, such as determining the optimal reef shape, selecting a suitable site in a certain sea area, and investigating ecology. Therefore, the reef body is constructed by combining a frame made of lightweight materials such as plastic.
The gist is to provide the main body of the fish reef with a weight adjustment device and a capture net.
本発明によれば、プラスチック等の軽量材で魚礁本体を
構成したので、複雑な形状とすることができ魚類が集ま
りやす（、また、重量調節装置により沈設時には魚礁を
重くし、運搬や設置には軽くすることでこれらの作業が
容易になるとともに、最適な魚礁位置に簡単に移動でき
る。According to the present invention, since the reef body is made of lightweight material such as plastic, it can be made into a complex shape, making it easier for fish to gather (also, the weight adjustment device makes the reef heavier when it is sunk, making it easier to transport and install. By making it lighter, these tasks become easier and you can easily move it to the optimal reef location.
さらに、魚礁本体に付設した捕獲網を使用することで、
例えば魚礁を浮−にさ−υる時に一挙に捕獲できる。Furthermore, by using a capture net attached to the fish reef body,
For example, when floating on a reef, you can catch fish all at once.
以下、図面について本発明の実施例を詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

２に形成し°ζある重量調節室３に連通ずる。The lower end of the water supply and drainage pipe 4 is connected to the center of the top of the fish reef body which has a truss shape and is opened in the vertical direction, and the branch pipe 5 that branches from there is first run along the top surface of the upper wall 1. The weight adjustment chamber 3 is connected to one end of the weight adjustment chamber 3 formed in the upper connecting member 2. Further, a branch pipe 5 is connected to the lower end of this weight adjustment chamber 3,
After the ``-'' side of the lower wall 1 is inflated, it is formed in the lower connecting member 2 and communicates with a weight adjustment chamber 3 located at °ζ.
前記注排水管４の上α＋；１に給餌装置６を取付げ、注

の海面上に移動する。Next, to explain how to install such an artificial fish reef in the sea, as shown in FIG. 4(a) and FIG. υ1 of water is discharged to reduce the weight on the reef body, and the fish reef body is moved to the sea surface at the sinking site by the work boat 11 while floating on the sea surface.
この作業船１１は魚礁本体Ａが海上面を浮遊するから、
小型のもので足りる。This work boat 11 has a fish reef main body A floating on the sea surface, so
A small one will suffice.

カー１０を使用する。Then, a trap 1111B is laid on the seabed at the sinking location, and water is injected into the water injection pipe 4 to supply water into the branch pipe 4 and the weight adjustment chamber 3, increasing the weight of the reef body A and allowing it to sink naturally into the sea.
It is deposited on the trapping net 8. At this time, one end of the water supply pipe 4 is installed so that it is located on the second side of the sea, and an anchor 10 is used as necessary.
こうして海底に沈設された魚礁本体Ａば、海面上の給餌

海上に浮−卜し浮遊する。To pull up the reef body A, as shown in Fig. 4(c), water in the weight adjustment chamber 3 is drained using the water supply pipe 4 and the branch pipe 5, which reduces the weight of the reef body A. It floats on the sea due to buoyancy.
そして、前記と同様にして作業船１１で新たな沈設場所
に移動したり、あるいは新たなものと交換する。Then, in the same manner as described above, the work boat 11 is used to move it to a new location, or replace it with a new one.

) As shown in Figures 5(c) and 5(c), the end of one coop 12 suspended from the work boat 11 is attached to the end of the capture net 8 (=JS,
When pulling up to the reef body, the rope 12 is also lifted so that the fishing net 8 is wrapped around the reef body, and the fishing net 8 is pulled to the reef body together.
そして、引」−げが完了したところで、魚礁本体Ａを捕
獲網８から引出して別の場所に移動し、捕獲網８の開「

を一挙に全部捕獲できる。Then, when the pulling is completed, the reef body A is pulled out from the capture net 8 and moved to another location, and the capture net 8 is opened.
By closing J, you can capture all the fish, shellfish, and seaweed that lived on the reef itself at once.
なお、魚礁本体への形状は本実施例に限るものではなく
、魚種や魚令に最適な形状を適宜決定すればよい。Note that the shape of the reef body is not limited to this example, and the shape that is most suitable for the species and age of the fish may be determined as appropriate.
