<；P>；PROBLEM TO BE SOLVED: To provide a method for raising a crustacean on an individual basis in raising vessels, efficient in raising management, through keeping the ambient condition inside the raising vessels well. <；P>；SOLUTION: The method for raising a crustacean is provided, being characterized by the following: The crustacean is accommodated individually in meshy raising vessels installed in a water tank. The raising vessels are injected with fresh water without stagnation and aerated thoroughly throughout the vessels. Raising management in the raising vessels such as observing, taking-up, feeding, etc. of the crustacean is easy to conduct. The raising vessels are detachable from the water tank and exchangeable with other raising vessels differing in size or mesh size therefrom, and installed in the water tank so as to lie off above the bottom thereof. Excrements and feed residues passed outside of the raising vessels move near the bottom of the water tank and are brought to the drain port of the water tank by water current in a definite direction and then are discharged out of the water tank. <；P>；COPYRIGHT: (C)2009,JPO&INPIT
