PROBLEM TO BE SOLVED: To provide an aquarium used for the growing and culturing of abalone and sea urchin by vertically successively installing aquariums installed successively with culturing cages, supplying water through a water spraying pipe, and supplying water to the downward aquariums by communicating an over-flow pipe with the insides of the aquariums, connecting it with a secondary water collecting pipe in its downward direction and with another water spraying pipe. SOLUTION: This multiple aquarium device for intermediate growth and culture is obtained by vertically successively installing aquariums 1 each having a rectangular shape and a horizontal upper surface, opened up only the upper surface, and installed successively with culturing cages 11. From a water spraying pipe 5 installed horizontally in longitudinal direction at the one side part of the upper side aquarium 1, water is supplied. Overflow pipes 7 are installed at the positions of a water level to be held at the side surface of the other end part of the aquarium 1 corresponding to the number and position of each of the culturing cages for communicating with the inside of the aquarium 1, and each of the over flow pipes 7 is introduced to the lower side at the outside of the aquariums 1. In the lower direction, the overflow pipes are connected to a secondary water collecting pipe 8 parallel to the longitudinal direction of the aquarium 1, which communicates with the water spraying pipe 5 at the lower side aquarium 1 and successively supplying water to the lower side aquarium 1.
