【考案の詳細な説明】
本考案は海中の適当な中間位置に浮かせて使用する浮魚
礁に関するものである。[Detailed Description of the Invention] The present invention relates to a floating fish reef that is used by floating it at a suitable intermediate position in the sea.
浮魚礁としては海面上に浮かせたシイラ漬け、或は一定
の水深をもって沈設した種々の形状の浮魚礁が知られて
いる。As floating fish reefs, there are known dolphin fish reefs floating on the sea surface, and floating fish reefs of various shapes that are submerged at a certain depth.
魚礁の目的は魚を集めることであるが、単に物影に隠れ
るだけではなく、魚礁に餌があることによってより一層
集魚効果が上るのである。The purpose of a fish reef is to attract fish, but rather than simply hiding in the shadows, the presence of food on the reef makes it even more effective at attracting fish.
従って、この餌は魚礁に発生する海藻に群がる小虫を餌
にする小魚、小魚を餌にする大きな魚と云うように魚礁
を設けることによって自然発生するのである。Therefore, this food is naturally generated by providing fish reefs, such as small fish feeding on the small insects that swarm around the seaweed that grows on the reef, and large fish feeding on the small fish.
しかしながら、従来の浮魚礁においては、餌の自然発生
の元になる海藻の発生が、例えば円筒形であるとか、傘
形である場合にはその周面にのみそれほどの変化もなく
平坦な状態でなされ、海藻の発生面積が小さいばかりで
なく、小魚の潜む場所も少なく集魚効果が小さい。However, in conventional floating fish reefs, when the seaweed that is the source of natural food growth is, for example, cylindrical or umbrella-shaped, only the peripheral surface remains flat without much change. Not only is the area where seaweed grows small, but there are also few places for small fish to hide, and the effect of attracting fish is small.
又潮流によっても海藻の発生の仕方が異なり、比較的平
面状を呈する円筒状もしくは傘形である場合には一方に
片寄った状態で海藻が発生し、そのために魚礁の大きさ
の割には餌の自然発生をもたらす条件が低下し集魚効果
が少ないと云う欠点もある。The way seaweed grows also varies depending on the current, and if the seaweed is relatively flat, cylindrical or umbrella-shaped, it will grow off to one side, making it difficult to feed fish considering the size of the reef. Another disadvantage is that the conditions for the natural occurrence of fish are reduced, making them less effective at attracting fish.
本考案はこのような実情に鑑みなされたものであって、
その目的は餌の自然発生条件を大巾に向上させると共に
小魚の潜む場所を多くして集魚効果を向上させた浮魚礁
を提供しようとするものである。This invention was created in view of these circumstances,
The purpose is to provide a floating fish reef that greatly improves the conditions under which food naturally occurs and increases the number of places where small fish can hide, thereby improving the fish-gathering effect.
この目的を達成するためになされた本考案は、ノング状
の枠体を適宜の間隔をもって上下に配し両者間を複数本
の連結ロープで連結して略円筒状になるように形威し、
該円筒状の内部に上面から見て全体的に星形を呈する筒
体になるよう網体を張設したことを特徴とする浮魚礁で
あって、上下の枠体間に張設された網体が星形を呈する
筒体であるため網体の表面積が多くなり、海藻発生量を
多くすると共に、星形の各辺の向きが区々であり、潮流
の影響によって海藻の発生が一方に片寄ることがなく全
体的に発生し、餌の自然発生条件が向上すると共に星形
によって小魚の潜む場所も多くなり集魚効果が向上する
のである。The present invention, which was made to achieve this purpose, consists of non-gang-shaped frames placed one above the other at appropriate intervals and connected by a plurality of connecting ropes to form a substantially cylindrical shape.
A floating fish reef characterized in that a net is stretched inside the cylindrical body so that the cylinder has a star shape as a whole when viewed from above, and the net is stretched between the upper and lower frames. Because the body is a cylinder with a star shape, the surface area of the net body is large, which increases the amount of seaweed generated.The sides of the star shape are oriented in different directions, so seaweed grows in one direction due to the influence of the tidal current. They occur all over the place without being concentrated, which improves the conditions for the natural occurrence of food, and the star shape increases the number of places where small fish can hide, improving the effect of attracting fish.
次に本考案を図示の実施例により更に詳しく説明すると
、1,2は樹脂で形成されたリング状の枠体であり、こ
れら枠体を上下に所定の間隔をもって配設し、両者間を
複数本の連結ロープ3により連結し、枠体と連結ロープ
とにより全体的に円筒状に形成する。Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numerals 1 and 2 are ring-shaped frames made of resin, and these frames are arranged vertically at a predetermined interval, with a plurality of They are connected by a book connecting rope 3, and the frame body and the connecting rope form a cylindrical shape as a whole.
これら連結ロープは望ましくは12本使用し、等間隔に
配置すると共に、1本おきに下方に延長し、延長した部
分を枝係留索3aとして利用し、該枝係留索の下端は一
纒めにして主係留索14に結着させである。Preferably, 12 of these connecting ropes are used, and they are arranged at equal intervals, and every other rope is extended downward, and the extended part is used as the branch mooring rope 3a, and the lower ends of the branch mooring ropes are tied together. It is tied to the main mooring rope 14.
上下の枠体1,2には夫々複数個の浮子4,5を取付け
て枠体自体に浮力を持たせ、浮子4,5の上部は個々の
浮子が首振りをしないよう浮子網6,7により連結させ
である。A plurality of floats 4 and 5 are attached to the upper and lower frames 1 and 2, respectively, to give the frames themselves buoyancy, and float nets 6 and 7 are installed above the floats 4 and 5 to prevent the individual floats from swinging. It is connected by.
このように枠体を連結させ、連結ロープ3により略円筒
状に形成された内部に上面から見て星形を呈し全体的に
星形を呈する筒体になるように綱体8を張設する。The frames are connected in this way, and the rope body 8 is stretched inside the approximately cylindrical interior formed by the connecting rope 3 so as to form a star-shaped cylinder as viewed from above. .
この場合、第3図に示したように、上下の枠体1,2に
予め星形になるような張網9.10を張設し、これら張

に沿って網体8を張設すれば網体8自体が、第4図に示
したように、全体的に見て星形を呈する筒体となるので
ある。In this case, as shown in Fig. 3, star-shaped tension nets 9 and 10 are stretched in advance on the upper and lower frames 1 and 2, and the tension nets 9 and 10 are vertically connected to each other from each intersection of the star shapes on these tension ropes. Auxiliary connecting ropes 3b are connected to the corresponding intersection points, and when the net 8 is stretched along the outer circumferential surface of the star, the net 8 itself becomes as shown in FIG. This results in a star-shaped cylinder.
もちろん前記筒体の上下端は夫々開口させである。Of course, the upper and lower ends of the cylindrical body are respectively open.
そして網体8の張設に当っては、連結ロープ3と補助連
結ロープ3bとに別の結着紐をもって結着させればその
取付けが簡単であり、又網体の上下端も星形を形成する
張網9,10に同様の結着紐をもって結着させれば良い
。When tensioning the net 8, it is easy to attach it by tying it to the connecting rope 3 and the auxiliary connecting rope 3b using separate tie strings, and the upper and lower ends of the net are also star-shaped. It is sufficient to bind the tension nets 9 and 10 to be formed using similar binding cords.
尚、この場合使用される網体8は角目網が好ましい。Note that the mesh body 8 used in this case is preferably a square mesh mesh.
図中符号11は上部枠体1に張設した星形張網9の各交
点に取付けた浮子であi’)、12.13は枠体の変形
を防止するために設けられた補強用ステーである。In the figure, reference numerals 11 are floats attached to each intersection of the star-shaped tension net 9 stretched over the upper frame 1 (i'), and 12 and 13 are reinforcing stays provided to prevent deformation of the frame. It is.

均等にしかも変化した部分が多く海藻の発生率が高くな
り餌の自然発生条件を一層良好にしているのである。As shown in FIG. 5, the floating fish reef of the present invention having the above configuration has an anchor member 15, such as a concrete block or a sandbag filled with pebbles, attached to the lower end of the main mooring cable 14 to which the branch mooring cable 3a is connected. The net is installed by being submerged at a predetermined depth in the sea, and the net 8 is stretched over a star-shaped cylinder, which increases the area of the net where seaweed grows. Because the star-shaped sides of the net face all directions, it is possible to prevent seaweed from growing when it is biased to one side due to the current, and the areas that have changed are almost evenly spaced throughout. This increases the incidence of seaweed, making conditions for the natural occurrence of food even better.
更に網体が星形を呈して張設されているため小魚の潜む
場所が多く、小魚が多く集まり、それによって小魚を餌
にする大きな魚(回遊魚)も集まるのである。Furthermore, because the net is stretched out in a star shape, there are many places where small fish can hide, attracting many small fish, which in turn attracts large fish (migratory fish) that feed on small fish.

。As explained above, the floating fish reef according to the present invention has a net for seaweed generation, which is the source of natural food generation, stretched in a star-shaped cylinder shape to increase its area, and a seaweed generation surface This increases the number of areas where the seaweed is oriented in various directions and is less susceptible to the effects of tidal currents, increasing the rate of seaweed growth and increasing the number of places where small fish can hide, thereby increasing the natural conditions for the formation of food for the target large fish. It has excellent effects.
