The present invention is directed to a multi-culture tank and drainage system. Due to the ecological characteristics of the sledgy cultured tank of the present invention, the water tank type tank and sludge that can be easily cleaned without entering the tank do not block the drain pipe through the drainage pipe or lose it to the outside because it moves and feeds the bottom and the wall. It consists of respective auxiliary tanks which consist of a sledge attachment prevention water supply pipe line 7 and a sledge attachment prevention prevention drain pipe tube. Aquaculture tanks are 90 cm to 100 cm wide and 30 m to 50 m long in length to facilitate easy cleaning and operation from the outside. Three culture tanks are numbered 1 and 2. No. 3 is connected to the tank culture water transfer pipe (10) to form a set. Each aquaculture tank consists of a water supply auxiliary tank and a drainage auxiliary tank, and the aquaculture water supplied to the aquaculture tank through the anti-slicing water supply pipe (7) flows out of the water tank and moves to the drainage auxiliary tank through the anti-slicing water drain pipe (8). Done. Aquaculture water supplied to the No. 1 tank water supply auxiliary tank 21 is returned to the No. 1 tank drainage auxiliary tank 22 and the No. 2 tank through the No. 1 tank No. 2 water tank feed water pipe (9). 2 to 3 tank culture water transfer pipe (10) through the 3 to the tank 3 flows through the water level control drain pipe 11 of FIG. Aquaculture tanks were maintained at the same level.Eating, Dementia, Sexual Lung, Loss, Drainage, Cultured Water, Mortality본 고안은 다슬기 양식 수조와 배수 시설에 관한 것이다. 본 고안의 다슬기 양식 수조는 다슬기의 생태 특성상 바닥과 벽면을 붙어서 이동하며 먹이활동을 하므로 수조에 들어가지 않고 쉽게 청소할 수 있는 수로형 수조와 다슬기가 배수 배관을 타고 배수관을 막거나 외부로 유실되지 않도록 다슬기 부착방지 급수관(7)과 다슬기 부착방지 배수관(8)으로 구성된 각각의 보조탱크로 이루어진다. 양식 수조는 외부에서 청소 및 작업이 용이하도록 양식 수조 넓이와 높이를 90cm~100cm로, 길이는 30m~50m의 수로 형태이며 3개의 양식 수조가 1번2번 수조 양식수 이송관(9), 2번3번 수조 양식수 이송관(10)으로 연결되어 하나의 셋트를 이룬다. 각각의 양식 수조에는 급수 보
