Biologi     Ordlista (t.ex. epibenthic)

A coastal pelagic species, to a lesser extent epipelagic to mesopelagic over the continental slope (Ref. 168). Are considered as straddling stock in the eastern central Pacific (Ref. 87829). Schooling by size is well developed and initiates at approximately 3 cm (Ref. 168); may also form schools with Sarda chiliensis, Trachurus symmetricus and Sardinops sagax (Ref. 9340). Adults stay near the bottom during the day; go up to the open water at night, (Ref. 5377) where they feed on copepods and other crustaceans, fishes and squids (Ref. 168). They spawn in batches (Ref. 51846). Eggs and larvae are pelagic (Ref. 6769). In Asian waters, they move to deeper water and remain inactive during the winter season (Ref. 4576). Commercially cultured in Japan. Marketed fresh, frozen, smoked, salted and occasionally canned (Ref. 9684). Eaten fried, broiled and baked (Ref. 9988). Used in Chinese medicine (Ref. 12166).

Livscykel och parningsbeteende Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver

Spawning most often occurs at water temperatures of 15° to 20°C. Spawn in several batches with 250 to 300 eggs per g of fish with the total number of eggs per female ranging from 100,000 to 400,000.
