Description

本考案は、底曳き漁法用漁網に関し、特に稚魚の乱獲を抑制して水産資源の再生産を促進することを可能にする、選択的漁業の実現を可能にする底曳き漁法用漁網の改良に関する。   The present invention relates to fishing nets for bottom fishing, and more particularly to improvement of fishing nets for bottom fishing, which enables the realization of selective fishing, which can suppress overfishing of fish and promote reproduction of fishery resources. .

従来から、底曳き漁法を利用すれば、種々の魚介類を一括して漁獲してしまうために、目的としない魚類や稚魚までも混獲するほか、ゴミなども一緒に集めたのち、これらを船上に引き上げてから選別して、不要の漁獲物やゴミなどを再び水中に投棄することは、止むを得ない手段とされていた。しかしこのような漁法では、投棄量が漁獲量に比べて多くなりがちであるから、労力の割に収獲量が少なくて経済的でないばかりでなく、水中に戻した魚体の損傷が大きく、水産資源の保護育成に逆行すると考えられている。   Conventionally, bottom fishing has been used to collect various fish and shellfish at once. It was considered unavoidable means to sort out unnecessary catches and garbage again in the water after they were lifted. However, in such a fishing method, the amount of discarded fish tends to be larger than the amount of fish catched. Is thought to go against the protection and fostering of children.

このような状況の下で、近時に至り、主として成魚だけを捕獲して稚魚を逃がすようにする漁網、又は目的の魚種だけを選択的に漁獲できる漁網を用いることで、水産資源の減少防止に役立てるという考えが理解されはじめ、種々の形式の漁網が提案されるようになってきている。   Under such circumstances, the reduction of fisheries resources can be prevented by using fishing nets that have recently come to catch mainly adult fish and escape fry, or that can selectively catch only the target fish species. Various types of fishing nets have been proposed, as the idea of using them has been understood.

そこで本考案は、異種の魚類や稚魚の混獲を回避して、目的の魚介類を効率的に漁獲することができ、従って水系における生物の生態系を維持すると共に、漁業資源の枯渇を防止して、継続的な水産業の繁栄に寄与することができる、底曳き漁法に用いられる漁網の、新規な構造を提案しようとするものである。   Therefore, the present invention avoids by-catch of different species of fish and fry and can efficiently catch the target fish and shellfish, thus maintaining the biological ecosystem in the water system and preventing the depletion of fishery resources. Therefore, it aims to propose a new structure of fishing nets used for bottoming fishing that can contribute to the continued prosperity of the fishing industry.

上記の課題を解決することができる本考案の漁網は、水中又は水底に棲息する水産動物を漁獲するための底曳き漁法用漁網であって、その袖網部分に続く網袋部分の前部を中目網からなる筒状網体で、該網袋部分の中部を大目網からなる窓部が天井位置に設けられている小目網からなる漏斗状網体で、また該網袋部分の後部を小目網からなる魚介類用の筒状網袋体で、それぞれ構成したことを特徴とするものであり、特に、前記網袋部分の中部における底位置に、中目網からなる雑物用の筒状下側網袋体の前端と接続する開口を設けたものとすることが、より好ましい。   The fishing net of the present invention which can solve the above-mentioned problem is a fishing net for bottoming fishing for catching marine animals living in the water or the bottom of the water, and a front part of a net bag part following the sleeve net part is provided. A cylindrical mesh body made of a mesh net, a funnel net made of a small mesh in which a window part made of a large mesh is provided at a ceiling position in the middle part of the mesh bag part. The rear part is a tubular mesh bag for fish and shellfish consisting of a small mesh, each of which is characterized in that the miscellaneous material consisting of a mesh mesh is provided at the bottom position in the middle of the mesh bag portion. It is more preferable to provide an opening that is connected to the front end of the cylindrical lower mesh bag body.

本考案の底曳き漁法用漁網は、袖網部分に続く網袋部分の前部が筒状になっていて、これに続く中部が漏斗状の小目網からなり、これに魚介類を捕捉する筒状網袋体が続いていることは、略従来の底曳き漁網と類似しているが、中部の漏斗状網の天井位置に、大目網からなる窓部を設けてなるものである。そのため、水底に沿って曳かれる漁網内に流入した水の多くは窓部から流出し、それと共に稚魚などの小型魚は、大きな網の目を潜って窓部から水と共に網の外に脱出できるのに対し、大きな網の目を潜れなかった成魚を中心とする大型魚は、後部の筒状網袋体内に入って捕獲されることになり、漁獲効率が高まると同時に、後日の漁獲量が減少に向かうことを予防することができる効果がある。   In the fishing net for bottom-trawl fishing of the present invention, the front part of the net bag part following the sleeve net part is cylindrical, and the middle part following this consists of a funnel-shaped small net, which catches fish and shellfish. The continuation of the tubular net bag is almost similar to the conventional bottom fishing net, but is provided with a window made of a large mesh at the ceiling position of the funnel net at the center. Therefore, much of the water that has flowed into the fishing net drawn along the bottom of the water flows out of the window, and at the same time small fish such as fry can escape out of the net along with the water from the window through a large mesh. On the other hand, large fish, mainly adult fish that could not dive through the large mesh, would be caught in the tubular net bag at the rear, increasing the catching efficiency and increasing the catch at a later date. There is an effect that it is possible to prevent the decrease.

更に、網袋部分の中部に設けた漏斗状網体の底位置に開口を設け、此処に雑物を収容するための下側網袋体の前端を接続すると、水底に生息する海老などの魚介類や、水底に散在している土砂、貝殻、ヒトデなどのゴミ類などの、漁網内に掬い取られものの内、転動するだけの雑物は上記の下側網袋体内に集められるが、自力で逃げようとする魚介類は下側網袋体には入らず、その上側に位置する魚介類用の網袋体内に入る。従って、魚介類と雑物との混獲が避けられて、網揚げや選別の際に魚介類の傷付きが起こらないから、漁獲物は高い活力を維持していて、商品価値が高いという利点もある。   Furthermore, an opening is provided at the bottom position of the funnel-shaped net provided in the middle of the net-sack, and the front end of the lower net-shaped net is connected thereto for accommodating miscellaneous materials. Among the things that are scooped into the fishing net, such as trash, sediment scattered on the bottom of the water, shells, starfish, etc., the miscellaneous that only rolls are collected in the lower net bag above, The fish and shellfishes that try to escape by themselves do not enter the lower net bag, but enter the fish net shell located above. Therefore, it is possible to avoid bycatch between fish and shellfish and miscellaneous materials, and the fish and shellfish will not be damaged during net-fishing and sorting. is there.

本考案の底曳き漁法用漁網を、図１に示す例によって説明する。
図１は、底曳き用漁網の海底で曳いているときの状態を示している。ここで１、１は一対の曳き綱(Trawl Warp)であり、その先端には漁網を拡開するためのオッターボード(Otter Board) ２、２が、それぞれ取り付けられている。そして、網袋部分(Cod) Ａとその前端左右位置から前方に延びる左右の袖網部分Ｂ、Ｂとの上縁及び下縁を、それぞれ補強しているヘッドロープ(Head Rope) ３及びグランドロープ(Ground Rope) ４の左右の前端が、上記のオッターボード２、２の後端の上部と下部とにそれぞれ結合されていて、網袋部分Ａが前端を左右に開いた状態で、曳き綱１によって曳かれながら前進するように構成されている。 The fishing net for bottoming fishing of the present invention will be described with reference to an example shown in FIG.
FIG. 1 shows a state in which a fishing net for bottom fishing is being pulled on the sea floor. Here, reference numerals 1 and 1 denote a pair of tow ropes (Trawl Warp), and Otter Boards 2 and 2 for expanding the fishing net are attached to the ends thereof, respectively. A head rope 3 and a ground rope which reinforce the upper edge and the lower edge of the net bag portion (Cod) A and the left and right sleeve net portions B, B extending forward from the front left and right positions thereof, respectively. The left and right front ends of the (Ground Rope) 4 are connected to the upper and lower portions of the rear ends of the otter boards 2 and 2, respectively. It is configured to move forward while being pulled by.

一方、上記のヘッドロープ３には、適宜の間隔で複数の浮子(Head Rope Floats)３ａが取り付けられ、またグランドロープ４には、適宜の間隔で複数の沈子(Sinkers) 又はグランドチェーン(Ground Chain)４aが結合してあり、前端上縁を上方に開いた網袋部分Ａが前端下縁を海底に接した状態で、引きずられて前進するようになっている。なお、海底に停留している魚介類を漁獲するために、長さがグランドロープ４より少し短く構成した、ビックリ用ロープ又は鎖(Tickler Chain) ４bなどを、網袋部分Ａの前端下縁より少し離れた前方の海底に接するように、設けることもできる。   On the other hand, a plurality of head ropes (Head Rope Floats) 3a are attached to the head rope 3 at appropriate intervals, and a plurality of sinkers or ground chains (Ground chains) are attached to the ground rope 4 at appropriate intervals. Chain) 4a is connected, and the mesh bag portion A having the front end upper edge opened upward is dragged forward with the front end lower edge in contact with the seabed. In addition, in order to catch the fish and shells which are anchored on the sea floor, a surprise rope or a chain (Tickler Chain) 4b having a length slightly shorter than the ground rope 4 is attached to the front end lower edge of the net bag portion A. It can also be provided so as to be in contact with the seabed slightly ahead of the sea.

本考案の漁網は、従来と略同様な上述の使用形態をとる底曳き漁法用の漁網であって、その網袋部分Ａが、大径で筒状の中目の網体からなる前部Ａ１と、漏斗状の小目の網体からなる中部Ａ２と、小径で筒状の小目の網袋体(Cod End) からなる後部Ａ３とを、直列に接続して構成されたものであるが、特に中部Ａ２の後部Ａ３に近い天井位置に、大目網からなる窓部(Window Net)５が設けられている点に特徴があるものである。   The fishing net according to the present invention is a fishing net for bottom-trawl fishing, which has the above-described usage form, which is substantially the same as the conventional one, and the net bag portion A is a front portion A1 formed of a large-diameter cylindrical mesh net. And a middle portion A2 composed of a funnel-shaped small mesh and a rear portion A3 composed of a small-diameter cylindrical small mesh bag (Cod End) connected in series. In particular, it is characterized in that a window (Window Net) 5 composed of a large mesh is provided at a ceiling position near the rear part A3 of the middle part A2.

このような構造を備えた本考案の底曳き漁法用漁網は、海水中に投入された後に曳き綱１、１によって曳かれると、グランドロープ４に取り付けられた沈子４ａ又はグランドチェーン４ｂが海底に達すると共に、ヘッドロープ３が、これに取り付けられた浮子３ａにより上方に引き上げられる。そして漁網が前方に進むと同時に、オッターボード２、２が水流の力を受けて左右の外方向に移動し、袖網部分Ｂ、Ｂを左右に押し拡げる結果、網袋部分Ａの前端が広く開いて網袋部分Ａの中に水が流れ込むようになる。   The fishing net for bottoming fishing method according to the present invention having such a structure, when put into seawater and pulled by the towing ropes 1, 1, causes the sediment 4 a or the ground chain 4 b attached to the ground rope 4 to be attached to the seabed. , The head rope 3 is lifted up by the float 3a attached thereto. At the same time as the fishing net moves forward, the otter boards 2 and 2 move outward in the left and right directions under the force of the water current, and push the sleeve net portions B and B right and left. As a result, the front end of the net bag portion A is widened. When opened, water flows into the net bag portion A.

この状態では、海底で移動又は休止している魚介類や、海底付近で遊泳している魚類などが、前進してくる網袋部分Ａの中に取り込まれるが、水と共に前部Ａ１から中部Ａ２へと進んで漏斗状網体６の径が小さくなるに連れて、魚類が逃れようとする動きは激しくなる。そうすると、大目網で形成された窓部５は水が流れ出やすいこともあって、稚魚などの小魚は窓部５の大目網を潜って網袋部分Ａの外に逃れ、大目網を潜り抜け難いような、主に商品価値の高い成魚や大型海老などが、後部Ａ３の小目の網袋体７内に集められることになる。従って、窓部５の網目ばかりでなく漏斗状網体６や網袋体７の網目の大きさを、それぞれ漁獲しようとする魚種や、逃がそうとする稚魚の大きさなどに応じて、適切に選定することが必要である。   In this state, fish and shellfish moving or resting on the seabed and fish swimming near the seabed are taken into the net bag portion A which is moving forward. As the diameter of the funnel-shaped net 6 decreases, the movement of the fish to escape increases. Then, since the water easily flows out of the window portion 5 formed of the large mesh, small fish such as fry escape the mesh net portion A through the large mesh of the window portion 5, and the large mesh Adult fish and large prawns having high commercial value that are difficult to pass through are mainly collected in the small mesh bag 7 in the rear part A3. Therefore, the size of the mesh of the funnel-like net 6 and the mesh bag 7 as well as the size of the mesh of the window portion 5 and the size of the fry to be caught, Appropriate selection is necessary.

このように、適切に設計された本考案の底曳き漁法用漁網を用いて、目的とする魚介類を漁獲すれば、漁網を漁船上に引き揚げた後に、漁獲物を選別するための労力を、効果的に削減できるばかりでなく、後日の漁獲量に影響を及ぼす恐れのある、稚魚などに対する被害も、大幅に減らすことができ、漁業資源の育成を図りながら、漁業収益の増大を達成することが可能となる。   In this way, if the intended seafood is caught using the properly designed bottom fishing net of the present invention, the effort to select the catch after the fishing net is lifted on the fishing boat, Not only can it be effectively reduced, but it can also significantly reduce the damage to fry, etc., which may affect the catch at a later date, and achieve an increase in fishery earnings while fostering fishery resources. Becomes possible.

ところが、上記のようにして海底付近に生息する魚介類を漁獲する際には、海底にある土砂、貝殻、ヒトデ、イソギンチャク、その他水中ゴミなどを、魚介類と共に網袋体７の中に混獲することになる結果、漁獲物を傷つける危険が増えるほか、漁獲物を選別をする手数も増えるという問題がある。   However, when catching fish and shells that live near the seabed as described above, sediment, shells, starfish, sea anemones, and other underwater trash on the seabed are co-caught in the net bag 7 together with the fish and shellfish. As a result, there is a problem that the danger of damaging the catch increases, and that the number of steps for selecting the catch increases.

そこで本考案の漁網においては、図２の例に示すように、前記網袋部分Ａの中部Ａ２を構成する漏斗状網体６の底位置に開口８を設け、好ましくは中目の網で形成された下側網袋体(Lower Net) ９の前端を該開口８に接続して、漁網の前端部で掬い取られて網袋部分Ａに入り込んだゴミ等の雑物を、この下側網袋体９内に収容できるように構成することができる。   Therefore, in the fishing net of the present invention, as shown in the example of FIG. 2, an opening 8 is provided at the bottom position of the funnel-shaped net body 6 constituting the middle portion A2 of the net bag portion A, and is preferably formed by a mesh net. The front end of the lower net bag 9 (Lower Net) 9 is connected to the opening 8 so that foreign matter such as trash that has been scooped by the front end of the fishing net and has entered the net bag portion A can be removed from the lower net 9. It can be constituted so that it can be stored in the bag body 9.

しかし該下側網袋体９は、雑物を収容した状態で海底を引きずられることになるため、余りに小さいゴミ類までを集めることは望ましくなく、該下側網袋体９を構成する網の目の大きさを、海底に散在する雑物の種類や分布の状況に応じて、適切に選定することが望ましい。また下側網袋体９の下側後半部には、例えば金網などの耐磨耗性の網体からなる補強材(Protection Wire Gauze) ９ａを設けておくのが良く、更に下側前半部には、海底から離れることがないように沈子９ｂなどを設けておくのが好ましい。   However, since the lower mesh bag 9 is dragged along the seabed in a state in which miscellaneous materials are stored, it is not desirable to collect too small garbage. It is desirable that the size of the eyes be appropriately selected according to the type and distribution of miscellaneous substances scattered on the sea floor. Further, a reinforcing material (Protection Wire Gauze) 9a made of an abrasion-resistant net such as a wire mesh is preferably provided in the lower rear half of the lower net bag 9, and further in the lower front half. It is preferable to provide a sediment 9b or the like so as not to leave the seabed.

このように、漁獲した魚介類を収容するための網袋体７に加えて、その下方に下側網袋体９を設けると、網袋部分Ａの前端部で掬い取られたゴミ等の雑物のうち、比較的に重く大型のものは、網袋部分Ａの底部を転がって下側網袋体９内に集まるが、移動する網の目を潜り抜けることができない魚類や海老などは、自力で動くから魚介類用の網袋体７内に入り込み、雑物と混じることが少ない状態で捕獲される。従って、曳き綱１、１を巻き取ることで、漁船上に引き揚げられた本考案の底曳き漁法用漁網では、稚魚や、商品価値の少ない小魚などの漁獲は少なく、商品価値の大きい大型の魚類や、網目を潜り難い海老などが、雑物とは分離されて多量に漁獲されることになる。   As described above, when the lower net bag 9 is provided below the net bag 7 for accommodating the caught fish and shellfish, miscellaneous matters such as trash scooped at the front end of the net bag portion A are provided. Of the objects, relatively heavy and large ones roll on the bottom of the net bag portion A and gather in the lower net bag body 9, but fish and shrimp that cannot pass through the mesh of the moving net, Since it moves on its own, it enters the fish bag 7 for fish and shellfish and is captured in a state where it is less likely to be mixed with foreign substances. Therefore, in the fishing net for bottom-trawl fishing of the present invention, which is pulled up on a fishing boat by winding the towing lines 1 and 1, the catch of fry and small fish with low commercial value is small, and the large and large commercial value. Fish and shrimp that are difficult to dive into the mesh are separated from miscellaneous materials and caught in large quantities.

そのため、本考案の底曳き漁法用漁網を利用することにより、漁業資源の枯渇を招きかねない稚魚の乱獲が避けられて、商品価値の大きい大型の成魚を中心とした効率的な漁労作業ができるうえ、選別作業が軽減できるほか漁獲物の傷みも少なく、従って鮮度のよい漁獲物を市場に供給できるという利益が得られる。   Therefore, by using the fishing net for bottom fishing method of the present invention, overfishing of juveniles which may lead to depletion of fishery resources can be avoided, and efficient fishing work can be performed mainly on large adult fish with high commercial value. In addition, there is an advantage that the sorting operation can be reduced and the damage of the catch is small, so that a fresh catch can be supplied to the market.

本考案の底曳き漁法用漁網は、海底付近に生息する魚類や海老などを、漁業資源の枯渇を防止しながら、効率的に漁獲するために考案されたものであるが、魚種については特に限定されるものではなく、底曳き漁法が利用できる海域又は水域であれば、特に制限無く漁業に利用することができる。   The fishing net for bottom-trawl fishing of the present invention is designed to efficiently catch fish and shrimp living near the seabed while preventing the depletion of fishery resources. There is no particular limitation, and any sea area or water area where bottom fishing can be used can be used for fishing without particular limitation.
