Estimates based on models

Preferred temperature (Ref. 123201): 13.9 - 23.5, mean 19.7 °C (based on 83 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00339 (0.00168 - 0.00685), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

營養階層 (Ref. 69278): 3.6 ±0.1 se; based on size and trophs of closest relatives

回復力 (Ref. 120179): 低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

價格種類 (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 28.4 [3.7, 536.4] mg/100g; Iron = 0.809 [0.075, 9.456] mg/100g; Protein = 15.7 [13.7, 17.7] %; Omega3 = 0.352 [0.141, 0.919] g/100g; Selenium = 57.8 [10.7, 304.1] μg/100g; VitaminA = 12.1 [0.9, 129.1] μg/100g; Zinc = 0.77 [0.04, 8.92] mg/100g (wet weight);
