| description | The invention relates to a method, a device and equipment for calculating barycentric coordinates of a fishing ground, and a storage medium, and the method comprises the steps: obtaining the catch per unit drift (CPUE) of a plurality of fishing areas of the fishing ground, carrying out the kernel density estimation of the obtained CPUE, and generating a fishing ground resource density index distribution diagram. And calculating the barycentric coordinates of the fishery by extracting the kernel density estimated value of the fishery resource density index distribution map. According to the method, the numerical value distribution of the CPUE and the relation between the CPUE and the fish catch of other surrounding fishing areas are considered through nuclear density estimation, the fishing ground gravity center calculation mode is more scientific, and guidance can be provided for fishing operation so as to improve the fishing efficiency.
