Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 8.0 cm TL mâle / non sexé; (Ref. 35388); common length : 4.0 cm TL mâle / non sexé; (Ref. 56527); âge max. reporté: 3.00 années (Ref. 56527)
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 9-11; Épines anales 0; Rayons mous anaux: 19 - 24. Silvery with a greenish-blue back (Ref. 4054).
Oceanic, found to depths of at least 1,524 m. Migrate in the water column at depths of 150-250 m during the day and to about 50 m at night (Ref. 57912, 107678). Mesopelagic (Ref. 5951); abundant near continental shelf-slope breaks and seamounts, rare in the open ocean (Ref. 107678). A cyclic selective feeder of copepods and euphausiids (Ref. 4739). They become sexually mature when 1 year old. Spawning takes place in March - September, producing 200-500 eggs, floating on the surface (Ref. 35388). Lipid content is 5.5 % in fresh body weight and wax ester is 15.3 % in total lipids (Ref. 8966).
Spawns at least twice in in a lifetime (Ref. 57912).
