PURPOSE: An aquarium fish shopping mall system using pattern recognition is provided to offer the species information, object information, and price of an aquarium fish selected by a user, thereby providing an experience similar to offline shopping. CONSTITUTION: A fish species pattern database (110) stores a pattern of each fish species. A fish species identifying unit (120) receives an image of an aquarium fish from a camera recording the inside of a water tank. The fish species identifying unit identifies the species of the aquarium fish. An image streaming unit (130) provides the image of the aquarium fish, which was recorded by using the camera, to a client connected through a network. A price information storage unit (160) collects or stores price information of each fish species.
