Estimates based on models

Preferred temperature (Ref. 123201): 15.7 - 23.8, mean 19.7 °C (based on 7 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01288 (0.00664 - 0.02501), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.48 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.13; tmax=12).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 74.1 [39.8, 140.0] mg/100g; Iron = 1.05 [0.58, 1.86] mg/100g; Protein = 19.5 [18.6, 20.4] %; Omega3 = 0.322 [0.218, 0.500] g/100g; Selenium = 23.9 [11.5, 46.3] μg/100g; VitaminA = 12.1 [3.6, 36.6] μg/100g; Zinc = 0.826 [0.580, 1.170] mg/100g (wet weight);
