With the rapid rise of global ocean temperature, the living environment of mackerel and herring has changed and it forced them to move north. This phenomenon has seriously affected the future development of local small-scale fishery companies. In order to deal with this potential crisis, the paper build a Fish Temperature Spatial Migration model. In order to predict the migration routes of the two kinds of fish, we use the method of Stepwise Regression Prediction to predict the sea temperature changes in Scotland over the next 50 years. In addition, we use the method of Kriging Interpolation to establish a three-dimensional model of fish group and ocean temperature on the plane coordinate, and get the range of herring migration to 62-70N, 11.5-15W, and mackerel migration to 64-75N, and 12-16W in the next 50 years. All in all, the trend of fish migration to the north is realized.
