Aiming to develop the biological resources of the Okhotsk Sea shelf zone, a remote study of regional featuresof the ice processes dynamics in fishing areas is important. One of the main fishing areas of the OkhotskSea is the West Kamchatka subzone — the northeastern sector of the water area to the east of 153°30′ E,bounded from the south by latitude 54° N. Dynamics of seasonal changes in ice cover is inherent in everyregion of the sea, regardless of the total area of ice. Geophysical processes affect the ice cover through acomplicated mediated correlation that includes changes of the atmospheric circulation parameters. Critical,anomalous states of the ice cover in the West Kamchatka fishing subzone and also the cause-effect relationsof its formation are revealed during the pollock seasons in 2006–2017. The mechanism of influence ofthermobaric conditions, confirming the influence of the Okhotsk tropospheric cyclone (OTC) and thePacific tropospheric crest on the formation of abnormal ice conditions in the Okhotsk Sea both in generaland in certain local areas is presented
