The eggs are pelagic, and are typically found at depths of 50 to 90 m. Juvenile pollock move into the shallow littoral zone for the first two years of life (Steele 1963). Juvenile pollock often use macroalgae in the rocky intertidal zone as a source of refuge and forage during this period (Rangeley and Kramer 1995). Adults leave the shallow littoral zones and swim in large schools throughout the water column. Adults show no substrate preference, but temperature is an important factor. Adults may be found at depths ranging from 5 to 325 m, but more typically between 35 and 130 m (Cargnelli et al. 1999)
