Estimates based on models

Preferred temperature (Ref. 123201): 15.9 - 25.2, mean 20.8 °C (based on 20 cells).

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

Bayesian length-weight: a=0.00347 (0.00157 - 0.00767), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=2).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Preiskategorie (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 41 [7, 209] mg/100g; Iron = 0.753 [0.193, 2.177] mg/100g; Protein = 19.5 [17.4, 21.6] %; Omega3 = 0.127 [0.054, 0.310] g/100g; Selenium = 50.5 [12.3, 139.9] μg/100g; VitaminA = 11.9 [4.4, 30.6] μg/100g; Zinc = 0.739 [0.361, 1.345] mg/100g (wet weight);
