この発明は、網漁具としての建網類に相当する定置網に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixed net, which corresponds to set nets as net fishing gear.
定置網は、一般に陸岸から沖に向けて垣網を垣根状に張
設し、この垣網の先端部に囲網を設けて、来遊する魚群
を垣網に沿って囲網の内部に誘導させ、この囲網内の開

入り込んだ魚を漁獲するようにさせている。ところか、
この囲網は垣紘ｊとの接続部分を入口として広幅に開口

っており、せっかく囲網に入った魚群か内部の開場を適
当に遊泳したのち、そのほとんとか出て有終、壺網内に
は極僅少数の魚しか入り込まずに漁獲効率が極めて悪い
という難点がある。In fixed netting, a net is generally set up in the form of a hedge from the shore to the offshore, and a corral net is installed at the tip of the net to guide incoming schools of fish along the net into the inside of the net. The fish are allowed to swim in the open areas of the net, and the fish that enter the nets set in the corners of the net are caught. However,
This net has a wide opening with the connecting part with Kakihiro J as the entrance, so it is easy for fish to enter, but on the other hand it is drawn to be exhibited. The problem is that after swimming, most of the fish come out and only a very small number of fish enter the net, making the fishing efficiency extremely low.
本発明はかかる従来の問題点を解消せんとなされたもの
で、その目的とするところは、魚を囲網内の開場に誘い
込んだのちは魚の習性を利用して出にくくシ、できるだ
け多くの魚を開場内に閉し込めて歩留まりのよい漁獲が
できるようにした定置網を提供することにある。The present invention has been made to solve these conventional problems.The purpose of the present invention is to lure fish into the open area of the enclosure and then use the fish's habits to make it difficult for them to come out and to catch as many fish as possible. To provide a fixed net that can catch fish with a high yield by confining the fish in an open area.

することとした。That is, in order to achieve the objective 1), the fixed net of the present invention has a fence 1; a first fence 2 having a first opening 4 on the inside and a cover 5 on the outer periphery; A second opening 7 is provided, and a lid 8 is provided on the outer periphery, and a second river net 3 connected to the first surrounding net 2; -th lead which gradually became narrower] = 16
and insert the tip of the fence net 1 into the same first guide port 6, and open the second second opening 4 and the second opening 7.
Through a funnel-shaped opening 10° 10 that gradually tapers from the first opening 4 to the second opening 7, and a second guide opening 11 that gradually narrows from the first 1st Kawaba l [to the second opening 7]. In addition, the proximal opening width 10 of the second guide port 11 is made wider than the distal end I'' width 1) of the first guide port 6, and the second guide port 11 has a It was decided that a diagonal net (ln diagonal net) 2 would be stretched towards the opening 7.
以下、本発明の実施例を図面に示して説明する。Embodiments of the present invention will be described below with reference to the drawings.
図面は本発明の一実施例である定置網Ａを示している。The drawing shows a fixed network A that is an embodiment of the present invention.
図において、１は垣網、２は第一囲網、又、３は第二囲
網である。In the figure, 1 is a fence, 2 is a first fence, and 3 is a second fence.
上記垣網１は、岸から沖合に向けて海を垂直に遮断させ
るように垣根状に張設されている。The fence 1 is stretched in the form of a hedge so as to vertically block the sea from the shore to offshore.

垣網１の先端部を介入させている。The first enclosure 2 is formed into a substantially box shape with an elongated width in the left and right direction, has an opening 4 inside, and has a pot # on the corner of the outer periphery. 5 is provided, and a first guide port 6 whose width is gradually narrowed toward the inside is opened, and the tip of the fence 1 is inserted into the first guide port 6.

第二囲網３とに共通した網部材となる。The second enclosure 3 has a second opening 7 whose interior is wider than the first opening 4, has a lid 8 on its outer periphery, and is stretched in a state continuous to the first enclosure 2. There is. In this case, the partition nets 9, 9 in the continuous portions are common net members for the first enclosure net 2 and the second enclosure net 3.

ている。Next, 10.10 is a funnel-shaped opening, and by opening a circular hole in the middle part of the partition #34, hanging a rope around the hole and pulling it toward the inside of the second opening 7. It is formed into a tapered shape gradually from the opening 4 toward the second opening 7. Also, 11 is a second guide port, which is gradually formed between the partition nets 9 and 9 from the first opening 4 toward the second opening 7. The width h1 of the proximal end of the second guide port 11 is made wider than the width 11 of the distal end of the first guide port 6, and the second guide port 11 and the funnel-shaped Mouth 10,
10, the first opening 4 and the second opening 7 are communicated with each other.
１２は傾斜網で、上記第二誘導口１１の先端寄り部分に
おいて第−開場４から第二開場°７に向けて上り傾斜に
張設されている。Reference numeral 12 denotes a sloped net, which is stretched upwardly from the first opening 4 toward the second opening 7 at a portion near the tip of the second guide port 11 .

ように張設されている。The bottoms of the first encircling net 2 and the second enclosing net 3 are stretched in contact with the seabed G so that no gaps are formed between them, and the slanted net 12 is connected to the bottom of the slanted lower end. is in contact with the seabed G,
Moreover, the upper end of the thin needle is stretched so that it remains submerged under the sea surface even at low tide.

入り込んで捕獲されてしまうのである。Therefore, when the fixed net A configured as described above is set up in the sea, if a school of fish is blocked by the fence net 1, this school of fish will follow the fence net 1 to the first guiding port due to its habit. 6 into the ileum 4. The fish guided in this way migrated around the opening 4, and some of them moved to the pot #13.
5, and a part of it will exit the first guide port 6 in the opposite direction, but at this time, the tip opening width of the first guide port 6 is 1.
Since the proximal eye width I11 of the second guide port 11 is wider than that of the second guide port 11, there are few fish that exit from the first guide port 6, and the fish move from the second guide port 11 at the inclination a! 12 and enter the second opening 7. In addition, while moving around the first opening 4 along the net, some of it enters the second opening 7 through the funnel-shaped opening 10, and in this way, it enters the second opening 7 through the second guiding opening 11 and the funnel-shaped opening 1010. When entering the second opening 7, the funnel-shaped opening 10 exists as a tapered protrusion when viewed from the second opening 7, so it is unlikely that the fish will go back through the funnel-shaped opening 10 due to their habit. For fish trying to go out of the mouth 11 in the opposite direction, since the slanted net 12 exists as an obstacle moving toward the front, the fish will move through the slanted net 12 rather than going over the top of the ψ slanted net 12. It is easy for the fish to make a U-turn while being guided along the lower surface, and therefore the fish that entered this second opening 7 (i'' lost their place and moved around the first opening 7, eventually entering the pot net 8. They end up being captured.

きる。As explained above, according to the present invention, it is easy to guide the fish that entered the first opening to the second opening, and after entering the second opening, it is difficult to go back, making it easy to enter and difficult to exit. Because of this structure, the yield of fish is improved and the catch amount can be increased.
