【０００６】
【作用】
本発明によれば、仕切板の張出板を水槽の幅方向の隣接する仕切板の側面に押し付けた状態で各仕切板を固定する固定手段を設けたから、隣接する仕切板同士を張出板の突設幅間隔に固定して循環する水流を受けても仕切板の揺動が少なくなり、貝類が張出板を介して仕切板間を容易に移動できるようになる。
【０００７】
【発明の実施の形態】
本発明の仕切板の配列方法としては、水槽の上端に複数本のハンガーを水の流れ方向と直交する方向に所定間隔おいて架設し、仕切板の両側上端に前記ハンガーに掛止する掛止片を形成し、同掛止片をハンガーに掛止して仕切板を水中に吊り下げできるようにしたものが脱着が容易に行えて好ましい。また、固定手段としては、水槽の壁面に面する仕切板の側面にボルトを水平に螺着し、同ボルトの先端を水槽の壁面に当ててボルトの螺着位置を変えることで仕切板の張出板を隣接する他の仕切板の側面へ押し付けて各仕切板を水槽に固定するようにしたものが、低コストで確実に仕切板同士を張出板の突設幅間隔に固定できる。
【０００８】
仕切板を構成する素材としては、繊維強化プラスチックに珪澡土及び必要に応じて所要の充填材を混入して構成したものが貝類の付着や育成が良好で且つ軽量で取り扱いが容易となり好ましい。また、張出板を上方から全部又は一部見えるようにずらして突設すると飼料の配置が容易に行える。さらに、仕切板の側面には開口を形成して通水と貝類の移動ができるようにしてもよい。
【０００９】
水槽の底隅部には気泡を放散する散気管を水の流れ方向に沿って配管すると、循環方向と直交する方向に対流を発生させてよりムラなく循環させることが可能となる。また、このとき仕切板の上端に邪魔板を部分的に突設すると、散気管で発生した対流の下降流が水槽の幅方向に均一に生じて好ましい。なお、仕切板の下方に貝類が通過できない網材を水槽の底面と所定間隔おいて敷設すると、貝類から排出された糞や落下した飼料を水底に沈澱させて水流で排出させることで水槽内を衛生に保持できる。
【００１０】
【実施例】
以下、本発明の実施例を図面に基づいて具体的に説明する。図１〜５に示す実施例はアワビを人工飼育する飼育装置に本発明を適用した例である。図１は実施例の仕切板の斜視図、図２は実施例の循環式飼育装置の平面図、図３は図２のＡ−Ａ断面図、図４は図２のＢ−Ｂ断面図、図５は実施例のアワビの配置を示す説明図である。図中、１は仕切板、１ａは掛止片、１ｂは邪魔板、２は張出板、３は開口、４は水槽、４ａは中仕切壁、４ｂは排水口、５はハンガー、６はボルト、７はネット、８は散気管、９はポンプ、Ａはアワビ、Ｓは飼料、Ｗは水である。
【００１１】
本実施例では、図１に示すように珪澡土及び充填材が混入された比重１．２のＦＲＰ（繊維強化プラスチック）からなる長さ６６０ｍｍ，高さ６００ｍｍの仕切板１の側面に断面Ｉ状の９５ｍｍ幅の張出板２を７箇ずらして突設し、上部及び中央部に通水及びアワビＡが行き来するための楕円状の開口３を４箇所形成している。仕切板１の両側上部にはハンガー５に掛止する掛止片１ａを形成するとともに、上端には対流の下降流を水槽４の幅方向に均一に生じさせる邪魔板１ｂを２箇所突設している。
【００１２】
図２〜４に示すように、前記仕切板１を中仕切壁４ａで仕切られた水槽４の両区画内に３体及び張出板２を省略した仕切板１を水の流れ方向に且つ水槽４の幅方向に沿って掛止片１ａをハンガー５に掛止して所定間隔に吊設し、水槽４の壁面に面する仕切板１の側面に螺着したボルト６の先端を水槽４の壁面に当ててボルト６の螺着位置を変えることで仕切板１の張出板２を隣接する他の仕切板１の側面へ押し付けて各仕切板１を水槽４に固定している。
【００１３】
仕切板１の下方にはアワビＡが通過できないネット７を水槽４の底面から所定間隔おいて敷設するとともに、水槽４両側の仕切板１下方に気泡を水中に放散させる散気管８を水の流れ方向に沿って配管し、図示しない空気供給装置で空気を給気するようにしている。
【００１４】
本実施例では、水槽４内に水Ｗを一方から給水するとともに他方でポンプ９により吸水して対向側に排水することで水槽４内を所定水速で時計廻りに循環させ、アワビＡの稚貝を各仕切板１の側面に付着させる。そして、図５に示すようにワムシやプランクトン類，藻類等の飼料Ｓを水槽４内に投下すると、飼料Ｓが水中を沈降して張出板２上に配置され、アワビＡが飼料Ｓを食して育成される。
【００１５】
アワビＡから排出された糞や張出板２に配置されなかった飼料Ｓの一部はネット７を通過して水槽４の水底に沈澱し、循環する水Ｗの流れとともに移動して排水口４ｂから外部に排出される。散気管８からは気泡が上方に放散され、その気泡で底面付近の水Ｗを上昇させて対流を生じさせるとともに、仕切板の上端に突設した邪魔板で対流の下降流が水槽の幅方向に均一に生じさせることで水槽内の水Ｗがムラなく循環される。
【００１６】
本実施例はこのように構成したから、仕切板１の張出板２を水槽４の幅方向の隣接する仕切板１の側面に押し付けた状態で各仕切板１を固定するボルト６を設けたことで、隣接する仕切板１同士を張出板２の突設幅間隔に固定して循環する水流を受けても仕切板１の揺動が低減できるとともに、アワビＡが張出板２を介して仕切板１間を自由に移動し易くなり、アワビＡの育成に貢献する。
【００１７】
【発明の効果】
以上説明したように、本発明によれば水槽に仕切板を列設後、循環する水流の力を受けても揺動を少なくするとともに貝類が仕切板間を移動し易くして貝類の育成に影響が出ないようにする貝類の循環式飼育装置を提供できる。

DETAILED DESCRIPTION OF THE INVENTION
As a method of arranging the partition plates according to the present invention, a plurality of hangers are installed on the upper end of the water tank at a predetermined interval in a direction perpendicular to the water flow direction, and the latches are hooked on the hangers at both upper ends of the partition plate. It is preferable that a piece is formed and the latching piece is hooked on a hanger so that the partition plate can be suspended in water because it can be easily detached. Also, as a fixing means, a bolt is horizontally screwed to the side surface of the partition plate facing the wall surface of the aquarium, and the end of the bolt is applied to the wall surface of the water tank so as to change the screwing position of the bolt. A structure in which each partition plate is fixed to the water tank by pressing the output plate against the side surface of another adjacent partition plate can reliably fix the partition plates to the protruding width interval of the extension plate at low cost.
[0008]
The material constituting the partition plate is preferably a fiber reinforced plastic mixed with kieselguhr and a necessary filler as required, because the shells adhere well and grow well, are lightweight and easy to handle. Further, if the projecting plate is shifted so as to be seen from the whole or a part thereof, the feed can be easily arranged. Further, an opening may be formed on the side surface of the partition plate so that water can be passed and shellfish can be moved.

If a diffuser pipe for diffusing bubbles is provided along the water flow direction at the bottom corner of the water tank, convection can be generated in a direction perpendicular to the circulation direction to circulate more uniformly. Further, at this time, it is preferable that a baffle plate is partially provided at the upper end of the partition plate, so that the downward flow of the convection generated in the air diffuser is uniformly generated in the width direction of the water tank. In addition, if a netting material that shells cannot pass below the partition plate is laid at a predetermined distance from the bottom of the aquarium, the feces discharged from the shellfish and the fallen feed settle on the bottom of the aquarium and are discharged by the water flow. Can be kept hygienic.
