Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 13; Rückenflossenweichstrahlen (insgesamt) : 10; Afterflossenstacheln: 7; Afterflossenweichstrahlen: 9; Wirbelzahl: 13. Body olive green or brown above, silvery below; fish frequently with a dark patch below origin of lateral line. Adults become mottled when frightened. Slender, pungent, venomous spines. Preopercular angle 89°-95°. Lower half to 2/3 of cheeks commonly covered with weak, scattered scales. Midline of thorax between pelvic ridges. Differs from S. argenteus in details of coloration and less deeply forked tail (Ref. 37816).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Inhabits algal and seagrass flats and shallow lagoon and coastal reefs (Ref. 9710, 11230). Forms schools. Mainly diurnal. Juveniles feed on filamentous algae, adults feed on leafy algae and seagrasses (Ref. 9710). Commercially cultured in Japan. Commonly found in large estuaries (Ref. 9002). Anterolateral glandular groove with venom gland (Ref. 57406).
Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven
In Belau, ripe individuals form prespawning congregations of 30-60 individuals in shoal areas of inner reef flats; spawning occurs on the 4th or 5th day of the new moon; spawning sites are near reef edge. About 300,000 eggs/female at a single spawning. Individuals that spawn in consecutive yrs. & that 2+ yr. class fish could spawn more than once in a single season. Aug (Ref 1754) in Belau.

Estimates based on models
Preferred temperature (Ref. 123201): 22.6 - 29, mean 27.9 °C (based on 760 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00820 - 0.02023), b=2.99 (2.86 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 2.0 ±0.1 se; based on diet studies.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
Nutrients (Ref. 124155): Calcium = 36.7 [18.1, 83.9] mg/100g; Iron = 0.709 [0.352, 1.481] mg/100g; Protein = 19.2 [17.9, 20.4] %; Omega3 = 0.145 [0.082, 0.262] g/100g; Selenium = 24.8 [10.9, 52.7] μg/100g; VitaminA = 34.4 [9.7, 114.8] μg/100g; Zinc = 1.8 [0.7, 3.5] mg/100g (wet weight); based on nutrient studies.
