て付くものと考えられている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pelagic fish reef and a fish gathering method using a pelagic fish reef.Fish are classified into demersal fish and migratory fish depending on where they breathe. Demersal fish live in rock ants on the ocean floor, and many of them spend most of their lives in the same sea area. On the other hand, migratory fish migrate through the upper and middle layers of the ocean, and some migrate hundreds to thousands of kilometers depending on the season. Fish migrating in the ocean like this also have the property of attracting driftwood, etc., floating on the sea surface. This dust elephant is called ``kitsuki,'' and it is believed that small fish are attracted to seaweed and owl attached to driftwood, so migratory fish attach to it in search of small fish. .
回遊魚、特に上層魚のこの様な性質を利、用して従来は
上層魚の回遊する海域にイカダを浮べておいてこれに上

。鉾通、回遊魚がせい息する海域は水深が1500〜2

置するためには、水深に見合つ九長い撃留ロープを必要
とするしイカダは潮流や風波の影畳に耐えるだけの堅牢
度と大きな浮力を備えていなければならない。Taking advantage of these properties of migratory fish, especially upper-layer fish, attempts have been made to float rafts in areas where upper-layer fish migrate and catch upper-layer fish when they are attached to the raft. Hokodori, the sea area where migratory fish live is at a depth of 1500~2.
(The distance is 100 meters, so in order to set up a raft in this area, you need nine long ropes that are commensurate with the depth of the water.The raft has enough sturdiness and great buoyancy to withstand the tides, wind, and waves. must be maintained.

もりも数トン乃至十数トンにも達する大きなものが使用
されることとなったのである。Moreover, most of the cost of installing a raft is spent on the holding rope, so in order to reduce the cost of installing a raft, it is necessary to make the raft large.
Conventional rafts are extremely strong and large, with a weight of 5 meters and 40,000 meters or more, and as a result, the rope used is over 30 mm thick and the weight is several tons. Large pieces weighing up to ten or more tons came to be used.

のでろる。It goes without saying that conventional rafts have the disadvantage of being expensive to install because of their overall large size, but especially when fishing for fish, the raft and mooring ropes get in the way of purse net operation. It would be a shame if a large number of fish were to be taken away because it would be impossible to trace back.

るる。The present invention solves the above-mentioned drawbacks of conventional rafts, and as mentioned earlier, upper layer fish attach to rafts because of algae and seaweed adhering to the rafts. Instead, a float is floated in the ocean, auxiliary ropes are connected to it, seedbeds are attached to the auxiliary ropes at appropriate intervals, and algae and seaweed are attached to these seedbeds to create fish reefs. By doing so, you can achieve the same fish-collecting effect as installing multiple rafts, and the cost of installing the rafts can be made much cheaper. At the same time, when fishing, the auxiliary rope can be untied from the float and the fish can be caught. By hoisting up the entire nursery, the efficiency of the purse seine is significantly increased, and the catch rate of fish is increased, which in turn increases the amount of fish caught.
以下本発明の一実施例を開部に基づいて具体的に説明す
る。EMBODIMENT OF THE INVENTION Hereinafter, one embodiment of the present invention will be specifically described based on the opening.
図中、符号■はフロート、■は撃留ロープ、■はアンカ
ーである。フロート■はイヵダの様にこれに礫などを付
着させて上層魚を付ける吃のではなく、後述する苗床■

のである。In the figure, the symbol ■ is a float, the symbol ■ is a locking rope, and the symbol ■ is an anchor. The float ■ is not used as a trap for attracting upper layer fish by attaching gravel etc. to it like a raft, but it is used as a seedbed ■ as described below.
There are no particular restrictions on its shape or size, as it is sufficient to keep it in one place on the sea surface and prevent it from being washed away! It is sufficient if it has the function of a 11Fi float. One or several auxiliary ropes (2) are attached to this, and seedbeds (2) are attached to the auxiliary ropes (2) at appropriate intervals. This nursery ■ is used to propagate grass, seaweed, etc. so that fish can attach to it.
そしてこのものは海面■上に突出する必要はなく、むし

ダの様に大形且つ堅牢なものではなく、例えば魚網を筒
状に巻いて形成した様な軟質のものが望ましいのである
。It is not necessary for this thing to protrude above the sea surface; rather, it is preferable for it to be suspended below the sea surface.Moreover, it is necessary for the person who carries out the purse seine to avoid getting entangled in the net and breaking it. It needs to be something that is not as large and sturdy as a raft, but rather something that is flexible, such as one made by winding a fishing net into a cylindrical shape.
また補助ロープ■はこれ自身が海面に浮かぶものでるる
ことが望ましいのであるが、このものが重い場合には適
所にブイのを取付けてこれが沈むのを防ぐものとする。It is also desirable that the auxiliary rope (2) floats on the sea surface, but if it is heavy, a buoy should be attached to the appropriate place to prevent it from sinking.
勿論、補助ロープ■としてはナイロン製ロープや麻縄が
用いらバるのであるが、何れも比較的軽くてその比重は
海水の比重に近似しているからブイのは小さなもので足
シることは云うまでもない。Of course, nylon rope or hemp rope can be used as the auxiliary rope, but both are relatively light and their specific gravity is close to that of seawater, so a small buoy can be used. Needless to say.
第二図は魚礁を立体的に構成した一例を示すものであっ

立体的にすれば一旦魚礁に付いた魚をのがすことが少な
くなるし、更には海洋の中層附近にまで垂らしておけば
、鮪などの中層魚も集めることができるようになり、魚
獲蓋を一段と向上させることができるのである。Figure 2 shows an example of a three-dimensional fish reef, in which branch ropes (2) are attached at appropriate intervals to the auxiliary rope (2), and seedbeds (2) are attached and swung to these. Normally, upper layer fish such as bonito do not always live near the sea surface, but sometimes move to depths of several tens of meters, so making a fish reef three-dimensional like this makes it easier to remove fish once attached to the reef. Furthermore, if you hang it near the middle layer of the ocean, you will be able to collect middle layer fish such as tuna, which will further improve your ability to catch fish.

ことが出来るのでおる。In addition, several auxiliary ropes ■ can be attached to one shogunate rope ■, and the branch ropes ■ can be attached to each auxiliary rope relatively densely, for example, at intervals of several meters, to create a forest of branch ropes. If this condition is maintained, it is possible to cultivate the bottomless fish that live on the relatively shallow seabed, and it is possible to catch fish from the bottomless fish itself. It is possible to reduce the amount of fish caught.
続いて上記した浮魚礁についた魚を漁獲する方法につい
て説明する。Next, a method for catching fish attached to the above-mentioned floating reef will be explained.

って巻上けるのである。First, when carrying out this fishing method, the auxiliary rope ■ should be attached to and detached from the shooting rope ■, and when there is a suitable amount of fish on the floating reef and the time is ripe to catch fish, the auxiliary rope ■ released from the rope. Then, the floating fish reef will float in the ocean with the fish attached to the seedbed, and the fish will be hoisted up together with the fish using a purse seine.

材料を用いて形成することが必要である。In this case, of course, the seedbed and buoy must be made of something that will not get entangled with or break the net, and must be made of logs or bamboo like a raft. Instead, it is necessary to use buoys without corners and to form seedbeds using flexible materials.

一層魚獲量が高められるのである。As detailed above, the present invention involves floating a float on the sea, connecting an auxiliary rope to it, and further attaching a large number of seedbeds to the auxiliary rope, and attaching gravel and seaweed to these to create a floating fish reef. The float and the mooring rope are used to confirm the position of the floating fish reef and also to prevent the auxiliary rope from being washed away, so the float is extremely small compared to a conventional raft, and the mooring rope is extremely small compared to a conventional raft. Since the robes only need to be thin, and the auxiliary ropes can be long enough, the number of seedbeds can be increased, so in the end, it will be comparable to dozens or more of the conventional rafts. (Compared to a raft, the installation cost is significantly cheaper and it is possible to collect a large amount of fish.In addition, when catching fish, the auxiliary rope must be untied from the shooting rope. The rope does not get in the way of the fish-catching work, and the fish are rolled up along with the nursery, so the work efficiency is extremely high.Furthermore, there is less chance of the fish escaping, which further increases the amount of fish caught. be.
