PROBLEM TO BE SOLVED: To provide an aquatic life aquaculture tank for solving problems in which it is difficult to confirm a state of aquatic life in a water tank by visual observation in the wide water tank, and still further, when the water tank is installed in a building, natural light may not pass and it is dark and cannot be seen.SOLUTION: Partition walls are extensively combined in conformity to a water tank, substantially perpendicularly to a water surface in an aquaculture water tank, and a horizontal plate-like walking route is mounted on upper ends of the partition walls. People can walk on the walking route freely, so that an underwater situation can be seen and visually confirmed from the upper part in the water tank. When the water tank is in a building or the state in the water tank cannot be seen in the natural light even outdoors during nighttime, a lighting unit is installed in the water in the water tank. In that case, if the lighting unit of a plane light emission is used as the lighting unit, a shade is hard to be made in the water, and therefore it is more preferable.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 広い水槽では水槽内の水生生物の状態を目視・確認することは難しい。また更に、その水槽が建屋の中に設置されたでは自然光が通らず、暗くて見えない。【解決手段】 養殖用水槽内の水面に対しほぼ垂直に、水槽に合わせて縦横に仕切り壁を組み合わせ、仕切り壁の上端に、水平な板状の歩行路を取り付ける。歩行路は自由に歩行できるので、水槽内の上部から水中の状況を目視・確認する事ができる。 水槽が建屋の中にある場合や、野外でも夜間などで自然光では水槽内の様子が見えない場合は、水槽内の水中に照明装置を入れる。その場合照明装置は面発光の照明装置を用いると水中内に陰ができにくいのでより好ましい。【選択図】図2
