Biologi     Ordlista (t.ex. epibenthic)

Oceanic and epipelagic, found above the thermocline (Ref. 9308). Feeds on fishes, cephalopods and crustaceans. Also caught as a by-catch of long lines with hooks intended for tuna. Marketed frozen and prepared as fish cakes and sashimi in Japan (Ref. 9308). Also prepared as sausages.

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Spawning is believed to occur mainly during the winter months, especially in warm offshore currents with surface temperature of about 25°C.
