Estimates based on models

Preferred temperature (Ref. 123201): 9.8 - 19.6, mean 14.1 °C (based on 398 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00398 (0.00216 - 0.00732), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.34 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 32.6 [7.4, 143.2] mg/100g ; Iron = 0.422 [0.122, 1.414] mg/100g ; Protein = 2.7 [0.0, 6.6] % ; Omega3 = 0.172 [0.050, 0.603] g/100g ; Selenium = 8.15 [2.10, 32.85] μg/100g ; VitaminA = 41.5 [5.0, 331.0] μg/100g ; Zinc = 0.758 [0.337, 1.872] mg/100g (wet weight);
