Estimates based on models

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

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.41 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 136 [82, 214] mg/100g; Iron = 1 [1, 2] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.142 [0.081, 0.236] g/100g; Selenium = 64.8 [36.3, 117.1] μg/100g; VitaminA = 16.4 [6.5, 40.4] μg/100g; Zinc = 1.12 [0.84, 1.52] mg/100g (wet weight);
