Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03162 (0.02336 - 0.04281), b=2.99 (2.90 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.22 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (tm=7; tmax=28).

Fishing Vulnerability (Ref. 59153): High vulnerability (55 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 51 [19, 129] mg/100g; Iron = 1.42 [0.63, 3.27] mg/100g; Protein = 18.3 [16.2, 20.6] %; Omega3 = 0.314 [0.107, 0.926] g/100g; Selenium = 79 [26, 194] μg/100g; VitaminA = 17.7 [4.5, 71.6] μg/100g; Zinc = 1.59 [1.02, 2.56] mg/100g (wet weight);
