Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 150 cm TL Männchen/unbestimmt; (Ref. 9988); max. veröff. Gewicht: 40.0 kg (Ref. 9988)
Rückenflossenstacheln (insgesamt) : 6 - 7; Rückenflossenweichstrahlen (insgesamt) : 29 - 36; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 17 - 22; Wirbelzahl: 24. Scutes absent. Compared to S. lalandi, the species' dorsoposterior corner of upper jaw is angular (versus rounded) and the pectoral and pelvic fins are almost equal in length (versus pectoral shorter than pelvic fin).
Adults exhibit shoaling habit (Ref. 9988). They feed on plankton. Juveniles are found among floating seaweeds (Ref. 12114, 12115). Collection of young is the basis for prosperous aquaculture in Japan. Raised in captivity and marketed fresh for sashimi (Ref. 9988).

50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.65 se; based on food items.
Generation time: 3.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Widerstandsfähigkeit (Ref.
