Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00427 - 0.01286), b=3.11 (2.96 - 3.26), 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.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Nutrients (Ref. 124155): Calcium = 59.1 [23.4, 127.3] mg/100g; Iron = 1.35 [0.70, 2.69] mg/100g; Protein = 17.6 [16.3, 19.1] %; Omega3 = 0.234 [0.093, 0.570] g/100g; Selenium = 99.9 [40.4, 227.8] μg/100g; VitaminA = 18.6 [6.3, 56.4] μg/100g; Zinc = 0.833 [0.553, 1.242] mg/100g (wet weight);
