Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (89 of 100).
Nutrients (Ref. 124155): Calcium = 45 [19, 111] mg/100g; Iron = 1.41 [0.72, 3.77] mg/100g; Protein = 19.6 [17.4, 21.9] %; Omega3 = 0.448 [0.165, 1.278] g/100g; Selenium = 59.7 [23.4, 133.7] μg/100g; VitaminA = 40.6 [11.6, 141.4] μg/100g; Zinc = 1 [1, 2] mg/100g (wet weight);
