The study is based on the structure of the fish identification system established in the year of 107. It integrates the design of a web cloud architecture system, Socket communication interface and fish identification system, so that the recognition speed of the cloud fish identification system can be better in the user's perception. The identification is completed. With this system, the user can quickly and easily identify the type of fish, and collect more fish-related photos through the user. In the future, the model of the training database can be increased to improve the recognition rate. Although the recognition rate is as high as 88%, there are still a few samples that need to be revised to make the overall system more complete. Finally, let the user experience the cloud fish identification platform, so that the system can enhance the awareness of fish in daily life.
