To provide a symbiosis place of fishes and vegetable.SOLUTION: A symbiosis place of fishes and vegetable is configured so that: a rearing box 10 is provided on a lower face of a rack body 20； plant planting tanks 30 are provided on upper faces of the rack body； each of both sides of the plant planting tank 30 comprises each of a water entering tank 40 and water exiting tank 50； a filtration set 60 is provided in the vicinity of the water entering tank 40 on an uppermost layer and is connected to a withdrawal motor of the rearing box through a water feeding pipe 64； a water exiting seat 52 has a water exiting hole； a through hole is provided on a bottom part of a hood； the water exiting hole is downward connected to the water exiting pipe； a siphon pipe is provided in the water exiting pipe and a positioning ratchet is provided on an outer wall of the siphon pipe, for adjusting position height of the water exiting pipe, thereby controlling water level height in overflow stream. A pipe joint and drainage pipe are provided and are connected to the water entering tank 40 on a lower layer through the drainage pipe 556, water is sequentially circulated in the plant planting tanks 30 from the upper layer to the lower layer, so that the plant absorbs fertilizer in the water, and water after subjected to filtration and purification can be returned to the rearing box 10 again.SELECTED DRAWING: Figure 17【課題】魚類と野菜の共生場を提供する。【解決手段】魚類と野菜の共生場は、ラック体２０の下面に養殖箱１０が、その上面に植物植栽槽３０が設けられ、植物植栽槽３０の両側に入水タンク４０と、出水タンク５０とが設けられ、最上層の入水タンク４０近傍に濾過セット６０が設けられると共に、給水管６４を介して養殖箱の揚水モータと連結し、出水座５２に出水孔が設けられ、天蓋の底部に透孔が設けられ、出水孔が下向きに出水管に接続され、出水管内にサイホン管が設けられ、その外壁に位置決めラチェットが設けられることにより、出水管の位置高低を調整することで、溢水時の水位高低を制御するようにし、管ジョイントと排水管とが設けられ、排水管５５６を介して下層の入水タンク４０に連結され、水を上から下へと一層ずつ順次に植物植栽槽３０を流通させることで、植物は水中の肥料を吸収摂取し、濾過浄化後の水を再び養殖箱１０内に流れ戻すことができる。【選択図】図１７
