Actinopterygii (ray-finned fishes) > Beloniformes
(Needle fishes) > Scomberesocidae
Etymology: Cololabis: Greek, kolos = short, truncated + Latin, labia = lips (Ref. 45335); saira: From the Japanese word 'saira' meaning spear (Ref. 6885).
Environment / Climate / Range
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 230 m (Ref. 9339). Subtropical, preferred 6°C (Ref. 107945); 67°N - 18°N, 137°E - 108°W (Ref. 54338)
North Pacific: Korea (Ref. 37630) and Japan eastward to Gulf of Alaska and southward to Mexico. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139).
Length at first maturity / Size / Weight / Age
Maturity: Lm 22.7, range 25 - 28 cm
Max length : 40.0 cm SL male/unsexed; (Ref. 39882); max. published weight: 180.00 g (Ref. 56527); max. reported age: 4 years (Ref. 72462)
soft rays: 12 - 15;
Vertebrae: 62 - 69. Caudal fin broadly and finely forked; pectorals small, truncate, first ray notably flattened (Ref. 6885). Dark green to blue on dorsal surface, silvery below, small bright blue blotches distributed haphazardly on sides; fins on lower part of body pale, others with darkened rays (Ref. 6885). Branchiostegal rays: 12-15 (Ref. 36573).
Adults are generally found offshore, usually near surface, in schools (Ref. 2850). Juveniles associate with drifting seaweed (Ref. 12114, 12115). Feed on small crustaceans, and eggs and larvae of fishes. May glide above the surface of the water when moving away from predators. Prey of Thunnus alalunga and other scombrids (Ref. 9339). Oviparous, with larvae neustonic (Ref. 36573). Eggs are attached to one another and to floating objects via filaments on the shell surface (Ref. 36573). Utilized dried or salted, canned and frozen; also used for fishmeal and pet food; can be pan-fried and broiled (Ref. 9988).

Phylogenetic diversity index (Ref. 82805
= 0.7812 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00240 (0.00122 - 0.00470), b=3.15 (2.97 - 3.33), based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.44 se; Based on food items.
Resilience (Ref. 69278
