形，長方形等ではその転がりが防止できる。 In addition, although the illustrated example shows that the bottom part of the present invention is formed in a square shape, the present invention is not necessarily limited to this. However, if the anchoring surface of the seabed is sloped or there is a strong tidal current, conventional hemispherical structures may topple over and roll away from their designated locations, but square, rectangular, etc. This will prevent it from rolling.
第３図は本考案の他の実施例を示したものであ

２の斜材１０の互に相隣る一方との間にのみ取付
けられた構造のものである。 FIG. 3 shows another embodiment of the present invention (in FIG. 3, the same reference numerals as in FIGS. 1 and 2 indicate the same members), which is attached to the second diagonal member 10. The inclined steel plates 16 are connected to the adjacent second diagonal members 10.
1 and 10 2 , and between 10 3 and 10 4 , the second diagonal member 10 is installed only between adjacent ones of the second diagonal members 10 .
第３図の如く傾斜鋼板１６を第２の斜材１０に
交互に取付けたものは、本考案の内部を流れる海
流がさらに複雑な流れを形成できるからプランク
トンの発生の促進さらに魚類の蝟集活動を助長で
きる効果がある。 As shown in Fig. 3, the inclined steel plates 16 are attached alternately to the second diagonal members 10, so that the ocean current flowing inside the present invention can form a more complicated flow, which promotes the generation of plankton and the aggregation activity of fish. It has a supportive effect.
本考案は回遊魚、中層性魚、底生性魚等の魚類
に好適であるが、本考案は難洗掘構造であるた
め、海底が砂層でも安定しており、特にヒラメ等
の蝟集場所として好適のものである。 The present invention is suitable for fish such as migratory fish, mesophore fish, benthic fish, etc., but since the present invention has a hard-to-scour structure, it is stable even on the sandy seabed, and is particularly suitable as a gathering place for flounder and other species. belongs to.
即ち、ヒラメは夜行性で日没と共に遊泳行動を
開始し、魚礁から魚礁へと渡り歩き、日の出と共
に魚礁の近くに蝟集し、砂中に身をかくすように
しながら魚礁に対し頭部を向けて定位し、ヒラメ
自身は魚礁の内部に入ることはない。 In other words, flounder is nocturnal and begins swimming at sunset, migrating from reef to reef, congregates near the reef at sunrise, and orients itself with its head toward the reef while hiding in the sand. However, the flounder itself does not go inside the reef.
他方、ヒラメは砂中に定位するので、その魚礁
は砂中に洗掘しない構断であることと、またヒラ
メの捕獲は１本釣り又は網によるが、１本釣りの
場合降された釣針が魚礁にからみつくことなく、
また網であれば魚礁に引掛ることのない構造であ
ることが要求される。 On the other hand, since flounder settles in the sand, the reef must be structured so that it does not scour into the sand, and flounder can be caught by pole-and-line fishing or with a net; without getting entangled in fish reefs,
Additionally, nets must have a structure that prevents them from getting caught on fish reefs.
本考案は前述した如く天頂部がドーム状の天蓋
６に形成されているため、１本釣では釣針が天頂
部のドーム状天蓋６の表面を滑つて本考案の外側

状天蓋６表面があるためトラス構造を形成する鋼
材部分に引掛かるおそれもなく、魚礁の外側、即
ちヒラメの定位部分に確実に落下させることがで
きると云う著効がある。 As described above, the present invention has a dome-shaped canopy 6 at the top, so when fishing by pole and line, the fishing hook can slide on the surface of the dome-shaped canopy 6 at the top and fall toward the outside of the device, and the net Even in this case, because of the dome-shaped canopy 6 surface, there is no risk of it getting caught on the steel parts forming the truss structure, and it is extremely effective in that it can be reliably dropped to the outside of the fish reef, that is, to the area where the flounder is located. be.
以上の如く本考案は鋼材をトラス構造に組付け
ると共に、天頂部にドーム状天蓋を取付け、さら
に該ドーム状天蓋の下側に傾斜鋼板の１又は２以
上を取付けることによつて魚礁内を流れる海流に
よつて小過流，乱流等を促進でき、従つてプラン
クトンの発生が促進され、魚類の蝟集行動を従来
以上に助長できると云う著効がある。 As described above, the present invention assembles steel materials into a truss structure, attaches a dome-shaped canopy to the top, and further attaches one or more inclined steel plates to the underside of the dome-shaped canopy, thereby allowing the flow of water within the reef. Ocean currents can promote small overcurrents, turbulence, etc., which in turn promotes the generation of plankton, which has the remarkable effect of encouraging the aggregation behavior of fish more than ever before.
