Estimates based on models

Preferred temperature (Ref. 123201): 15.6 - 20.8, mean 17.7 °C (based on 33 cells).

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

Bayesian length-weight: a=0.00813 (0.00407 - 0.01621), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

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

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 99.4 [60.2, 181.3] mg/100g; Iron = 0.975 [0.593, 1.618] mg/100g; Protein = 17.1 [14.9, 19.0] %; Omega3 = 0.155 [0.087, 0.266] g/100g; Selenium = 86.1 [42.3, 172.0] μg/100g; VitaminA = 27.3 [9.3, 78.7] μg/100g; Zinc = 0.974 [0.685, 1.375] mg/100g (wet weight);
