Estimates based on models

Preferred temperature (Ref. 123201): 12.7 - 26.6, mean 19.3 °C (based on 438 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5029 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00279 - 0.01364), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.67 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 8.53 [3.49, 18.17] mg/100g; Iron = 0.194 [0.092, 0.404] mg/100g; Protein = 17.5 [16.2, 18.9] %; Omega3 = 0.18 [0.09, 0.37] g/100g; Selenium = 12.2 [4.4, 31.9] μg/100g; VitaminA = 51.5 [9.4, 295.6] μg/100g; Zinc = 0.431 [0.256, 0.685] mg/100g (wet weight);
