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=0.00537 (0.00239 - 0.01205), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.2   ±0.2 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 (17 of 100). 🛈
Nutrients
(Ref. 124155) 		Calcium = 267 [100, 569] mg/100g; Iron = 1.51 [0.84, 2.58] mg/100g; Protein = 17.8 [15.5, 20.4] %; Omega3 = 0.43 [0.13, 1.56] g/100g; Selenium = 53 [18, 154] μg/100g; VitaminA = 126 [43, 335] μg/100g; Zinc = 3.11 [2.08, 4.58] mg/100g (wet weight);
