簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 2; 背的軟條 (總數) : 5 - 7; 臀棘: 0. Diagnosis: second or third branched dorsal-fin ray longest (except in juveniles in which the first is the longest), but never filamentous; adipose fin small, its base shorter than or equal to dorsal-fin base; high number of branched pectoral-fin rays (usually 9, rarely 8); 12-16 (most often 13 or 14) stout and crenulate gill rakers on lower limb of first gill arch; there are important differences among the various populations of this species, and sexual dimorphism is noticeable between mature specimens in reproductive activity and immature individuals, more pronounced in males than in females and increasing with growth (Ref. 57126).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00439 - 0.01251), b=2.90 (2.76 - 3.04), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

回復力 (Ref. 120179):  中等的, 族群倍增時間最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (45 of 100).
Nutrients (Ref. 124155):  Calcium = 120 [71, 225] mg/100g; Iron = 1.39 [0.84, 2.30] mg/100g; Protein = 16.4 [15.4, 17.5] %; Omega3 = 0.254 [0.106, 0.603] g/100g; Selenium = 78.8 [36.0, 189.1] μg/100g; VitaminA = 26.7 [10.3, 63.9] μg/100g; Zinc = 1.73 [1.21, 2.46] mg/100g (wet weight);
