The invention discloses a culture pond change detection method and device, and a computer readable storage medium. The method comprises the following steps: training by using a marked culture pond training sample set in advance to obtain a culture pond instance segmentation network model; respectively inputting an early-stage remote sensing image and a later-stage remote sensing image of a to-be-detected culture pond into the culture pond instance segmentation network model to obtain instance segmentation results corresponding to the front-stage remote sensing image and the later-stage remote sensing image; and based on an instance segmentation result, respectively extracting vector contours of the front-stage remote sensing image and the later-stage remote sensing image, and finally determining an amplification area of the to-be-detected culture pond in a time period corresponding to the acquisition moments of the remote sensing images in the front and back periods according to the vector contours of the ear
