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=0.00490 (0.00323 - 0.00742), b=3.09 (2.97 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

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

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 123 [47, 262] mg/100g; Iron = 1.75 [0.91, 3.55] mg/100g; Protein = 16.9 [15.6, 18.2] %; Omega3 = 0.296 [0.122, 0.707] g/100g; Selenium = 92 [41, 225] μg/100g; VitaminA = 31.3 [11.3, 86.8] μg/100g; Zinc = 1.3 [0.9, 1.9] mg/100g (wet weight);
