Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00602 - 0.00955), b=2.91 (2.85 - 2.97), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.53 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23, assuming Fec > 10,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 48.6 [17.3, 139.4] mg/100g; Iron = 1.17 [0.61, 2.28] mg/100g; Protein = 17.6 [16.0, 19.3] %; Omega3 = 0.335 [0.106, 0.979] g/100g; Selenium = 118 [48, 267] μg/100g; VitaminA = 20.7 [4.7, 81.5] μg/100g; Zinc = 0.328 [0.203, 0.608] mg/100g (wet weight); based on nutrient studies.
