In this work we have attempted to mathematically describe chub mackerel (Scomber japonicus) and sardine (Sardinops sagax melanostricta) migrations, and construct a model and verify it by retrospective forecast. Three models are described. The first is constructed based on a linear migration model excluding any environmental factors. The second is constructed by taking into account the thermocline depth. The third model adds the additional characteristic of a temperature gradient in the thermocline. Positive results permit predicting migrations one month in advance for April-June and September-October for chub mackerel and for January-April and September-October for sardine.
