<p>Provided is a drainage system of a two-storied aquaculture tank, consisting of: a tank body having constant height and length, where an upper direction is opened; a water distribution hole formed to be lower than a tank bottom surface on one side bottom part of both ends of the tank body; and a drain pipe connected with the water distribution hole and installed on the outside of the tank body. The drainage system forms a structure of a drainage hole on the outside of the tank unlike forming the same on the inside of the tank. Accordingly, the drainage hole of the two-storied tank can be simply assembled and disassembled so that working time and installation costs needed for maintenance can be reduced. Also, feed residues and pollutants formed in the tank can be simply discharged through the water distribution hole formed on one side in the tank.</p> |
