Bayesian length-weight: a=0.00437 (0.00271 - 0.00704), b=3.07 (2.93 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

營養階層 (Ref. 69278): 3.8 ±0.63 se; based on food items.

回復力 (Ref. 120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

價格種類 (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 126 [54, 243] mg/100g; Iron = 1.55 [0.93, 2.46] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.275 [0.116, 0.669] g/100g; Selenium = 69.6 [31.2, 151.4] μg/100g; VitaminA = 33.5 [12.8, 91.3] μg/100g; Zinc = 1.26 [0.86, 1.81] mg/100g (wet weight);
