Pollock lives in cold waters (from +2 to +9 ° C), preferring depths from 200 to 300 meters, although it can migrate, dropping to depths of 500 - 700 meters and deeper. Pollock lives about 15 years. During spawning, the pollock approaches the coast, swimming in shallow waters 50 to 100 m deep. The pollock spawning grounds are very dense. Spawning itself in various parts of the Pacific Ocean begins at different times. So the pollock spawning in the Bering Sea happens in spring and summer (from March to September), off the coast of Korea - in winter and spring (from November to March), near Kamchatka - in spring. At the same time females can spawn even at low temperatures (-1.8 ° C). Caviar develops in the 50-meter surface layer.
