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=0.00891 (0.00408 - 0.01946), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.4   ±0.4 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (14 of 100). 🛈
Price category
(Ref. 80766) 		Medium.
Nutrients
(Ref. 124155) 		Calcium = 558 [137, 1,851] mg/100g; Iron = 1.51 [0.54, 3.62] mg/100g; Protein = 18 [16, 20] %; Omega3 = 0.279 [0.121, 0.556] g/100g; Selenium = 100 [29, 309] μg/100g; VitaminA = 41.6 [14.2, 131.0] μg/100g; Zinc = 2.63 [1.21, 4.84] mg/100g (wet weight);
