  • Method for predicting depth distribution of predetermined water temperature zone, method and system for delivering fishing ground prediction information of migratory fish
    Patent number: 7818280
    Abstract: A linear regression equation, ?1=?(?×h)+?, is obtained based on a depth h to a water zone of a predetermined water temperature, respective densities ?1 and ?2 of upper and lower layers above and below the water zone, and an absolute dynamic topography ?1 obtained based on data measured by satellite (?=(?2??1)/?2). Further, h? (depth of the water zone of the predetermined water temperature at each of a large number of spots) is determined according to this equation, ?2=?(??×h?)+?, based on ?? for each of the large number of spots calculated based on historical data, an absolute dynamic topography ?2 at each of the large number of spots based on data measured by satellite, and the values ? and ?.
