Results of the research indicate that the eggs of Atka mackerel are a part of forage for this speciesis from May to December. Captures of the Atka mackerel individuals spawning and feeding on the own eggs far from the coast indicate that a certain part of the stock spawns at the depths considerably lower than normal spawning grounds. Spawning individuals of Atka mackerel is were observed in research from June to December. Emergence of larvae from the eggs laid in November–December is expected in spring.
