Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.01177 - 0.03383), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

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

Preiskategorie (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 96.4 [51.8, 204.5] mg/100g; Iron = 1.47 [0.81, 3.03] mg/100g; Protein = 19.4 [17.8, 20.9] %; Omega3 = 0.492 [0.189, 1.440] g/100g; Selenium = 64 [27, 137] μg/100g; VitaminA = 55.2 [11.6, 208.0] μg/100g; Zinc = 1.14 [0.75, 1.80] mg/100g (wet weight);
